Planned merger of Applied Materials and Tokyo Electron failed

The announced eighteen months ago merger of the two companies from the USA and Japan has met with opposition from the US antitrust authorities. The promise of more competition does not suffice to competition watchdogs.

The cartel investigations in the US Department of Justice issued the merger plans drawn up by Applied Materials and Tokyo Electronics clearly rejected. The recent concessions of the two companies to provide for the merger to more competition, not enough auditors. Applied Materials wants to buy back its own action worth about three billion dollars (about 2.77 billion euros) in the market.

In September 2013, the California service and manufacturing companies and the Japanese producer of flat screens and machines for the semiconductor industry had announced their plans for a merger. The merger should arise a new heavyweight for equipment, software and services in the semiconductor industry and the production of chips and displays, such as for smartphones.

Had the merger of Applied Materials and Tokyo Electron been completed, a market value $ 29 billion was for the emerged from the merger company with a planned new headquarters in the Netherlands worden.Die predicts shareholders of Applied Materials should with 68 percent of the majority of shares hold in the new company. From the merger, the two companies promised not only to accelerate the development of new technologies for semiconductors and displays, but also a savings of 500 million euros annually.

Enables remote measurements of diode power sensor

Previously, power meters are grouped together by the power meter external power sensors and a host via a cable connection. In the radio-frequency power sensor signal is converted into a voltage signal, amplified, after digitization, is displayed in the host. This has the advantage that you can choose the appropriate power sensor for the current task, without the need to replace the power of the host, the downside is that the power sensor can not work independently, it can not be used without a host.

Now, with advances in semiconductor technology, power meter can be made into a small, integrated unit, and can be via a standard USB interface to connect directly to a PC or a power meter host. Rohde & Schwarz has recently released a new R & S NRPxxS and R & S NRPxxSN USB interface three-channel diode power sensor. The new three-channel diode power sensor products with greater flexibility, in addition to the existing USB interface probe, there is a new LAN interface, so you can easily achieve the long-distance power measurements.

The new diode power sensor has about features:

A wider range of frequencies

Both models have three selectable power sensor frequency range: 10 MHz to 8 GHz or 18 GHz or 33 GHz

Superior measurement speed

10,000 times per second, to be completed by the measurement trigger, trigger a minimum resolution of 100μs. Probes specific models can even be completed per second over 50,000 such interval measurement. Improved design allows three-channel diode power sensor can measure lowering the minimum -70dBm. New models with up to 93dB of dynamic range. At low power measurement speed improvement is particularly evident.

Through the LAN interface and a web browser control

The new LAN interface enables remote power measurement distance. For example, in a satellite system or a particle accelerator system in place certain position some power sensors can be completed on the computer control and monitoring control center. Power sensor can be easily controlled through a web browser, a graphical user interface, without having to install additional software.

Diverse and versatile measurement mode

Can help mobile communication users GSM, 3GPP, LTE and LTE-A signal power measurement. Can also be used to measure the 33GHz automotive collision avoidance radar development and production. In addition, new models can still measure the continuous average power, average burst power, average power slot, the average power gating and power curves.

Metering pump detects pressure variations without external sensors

The magnetic sensor as
On the way to increasingly high-quality chemical products the exact dosage is becoming increasingly important. For the dosing affects not only on the reproducibility of the quality of products produced from, but can also increase the profit margin by a security surcharges are metered. If the metering pumps used then also monitor nor even, also increases the availability of the production process.

These and other requirements were the focus of development efforts for the new dosing pump gamma / X Prominent - the successor model of the proven series gamma / L. First comes a controlled magnetic drive is used, which has been so designed that it can also monitor the hydraulic conditions.

In conventional dosing pressure sensors are integrated to detect pressure in the liquid. The electronic components and connectors are exposed to the metered, often aggressive chemicals that can be attacked and corroded. The necessary components and additional sealing surfaces also increase, depending on the model, the price of around 15 to 20 percent. The new pumps do not require such sensors. Their magnetic control covers all variations in pressure and protects the system from overpressure. So unnecessary sources of error are excluded.

Trouble-free dosing even with effervescent media
An example of typical problems in the use of metering pumps in practice are effervescent media. Thus, gas bubbles can completely block the dosage of chlorine bleach. This may in waterworks, where the operator is not always on site, result in impairment inserts. This not only causes loss of production, but additional costs.

An automatic venting of the metering pump prevents outgassing media disturb the dosage by gas bubbles and optimize the dosing. In addition, the new solenoid diaphragm detects varying pressure conditions and adjusts their dosing automatically to the currently prevailing conditions - even with highly viscous media. Viscosity changes caused by temperature variations are automatically compensated. The control automatically ensures trouble-free dosing. The new legislation also increases the accuracy of ± 5% to ± 2% or better. As a result, product quality and productivity can be increased.

The magnetic control detects selbstätig hydraulic deviations that interfere with the metering considerably. Overpressure, broken pressure lines or vacuum and gas in the liquid can be registered without sensors and processed. This pressure is indicated on the display. When exceeding or falling below a preset limit values ​​on the display, an alarm is displayed and transmitted via relay or bus interface. The timely detection and switching off the system and pump help to prevent damage. The integrated pressure monitoring is a reliable backup system to the existing pressure gauge and pressure relief valve. The pressure in the display simplifies commissioning, monitoring and troubleshooting, and thus reduces downtimes considerably.

High accuracy and intuitive operating concept
The pump is used for the dosage of 1 ml to 45 l / h at a back pressure of 25 to 2 bar. Your control range is 1: 2,000, reproducible accuracy within ± 2%. Other features of the new pump series also includes the installation and intuitive operating concept. In a fortified with standard tool mounting plate, the new solenoid is simply connected. For installation and positioning almost no restrictions must be observed, the status LED will be readily apparent from every angle. The unique pin assignment prevents incorrect assignments. Simple and front-access controls and clear messages from the large display simplify maintenance.

The pump is equipped with a large, illuminated graphic display with plain text in many languages. Use the Click Wheel newly developed is possible a rapid adjustment of the parameters. The Quick Access is via four buttons without cumbersome long scrolling in various operating levels. The feed rate is adjusted directly in liters per hour. Stroke, frequency and dosing profile can be parameterized. By a pressure gauge gives a short glance at the display information about the existing pressures. The three-stage LED status indicator, which is attached to the upper front panel displays from all sides visible from the current operating status.

The stroke length can be adjusted electronically in the range from 0 to 100 percent. If a pulsation or continuous dosing is required, it allows the controlled magnetic drive, execute the print stroke slowly. In the volume-proportional dosing of a chemical in a main stream continuous dosing characteristic is obtained in the form of an elongated metering stroke. Since both media are already well mixed in this way, is mixing elements can be saved in the main stream.

Static mixer unnecessary
For applications for pH regulation, for example in water levels, may as "chemicals clouds" are avoided. The slow pressure stroke the pH-regulating chemical is added to the water flow evenly. The water then has a nearly constant pH and arrives without pH variation to the consumer. The cost for an additional static mixer and its installation can be saved.

In the case of rigid dosing also can smoothest flow metering characteristic be necessary to prevent pipeline or pump will be damaged by strong pulsations of the incompressible dosing liquid. This requirement is mastered by the new pump.

Conclusion: The new solenoid diaphragm gamma / X-wear, overload and energy saving. As a first metering pump in its class, it is driven by a regulated magnet. In addition to high dosing accuracy and high efficiency, it can help to improve process safety through automatic monitoring of hydraulic conditions and sensorless pressure monitoring.

E-Facts
For operators
The more precise the control of a metering pump, the better the dosing.
The solenoid gamma / X is equipped with a low-wear, controlled magnetic drive.
Together with an automatic air vent and the detection incorrectly sized suction / discharge lines makes the new drive for high reliability.
The magnetic regime embraces Durckabweichungen and protects the network without additional (error-prone) sensors against overpressure.

Sharp plans to sell its headquarters and close Mihara LED factory

Various possible applications of wireless optical communication has slowly emerge

Optics in the semiconductor, electronics, using a wide range of ICT industries, such as optoelectronic semiconductors can be used as LED lights, lighting; Opto Semiconductors CCD, CMOS image sensors do digital cameras, digital surveillance, micro-electromechanical systems do DMD projector; Phototransistor, couplers for automatic control.

Or optical storage, such as Blu-ray Disc BD-chip; or optical communication, such as FTTH FTTH broadband, and optical communications is actually divided into wired and wireless, wireline, such as fiber to the House, that xPON various passive optical network; or large enterprise IT room, storage area network SAN within the data centers used; consumer electronics field, as in the past Sony MD with optical S / PDIF audio transmission line; or in the professional video editing regard, Apple Mac optical version Thunderbolt (referred TBT) transmission line.

Cable transmission of light has been used a lot, but rarely use wireless transmission, especially in the field of consumer end, almost all stay in the IR infrared remote control stage, and then the last few years people began to advocate the visible wireless communications VLC, estimated future a few years there will be a new development.

Why wireless optical communications to start showing off? Because the existing Wi-Fi in 2.4GHz spectrum resources have been squeezed almost to the limit, you want a faster rate, almost all to consider the 5GHz band, IEEE 802.11ac is the case, LTE-U is true, but not the global access 5GHz The band, some countries can not be used, or only partially used, conditional use (not for outdoor use, or may not exceed the number of transmit power).

In addition to 2.4GHz, another global access is available band 60GHz, but because the band is too high, the relevant design are highly difficult, is still developing. Plus LED popularity, people began to consider the use of wireless communication to accelerate the transmission of light in the region.

About this, the most representative of the technology for Li-Fi, has demonstrated over the 2014 CES, the fastest way transmission 150Mbps, two-way down to 110Mbps, in fact only a single antenna 11n Wi-Fi is almost, but the future There greatly enhance the potential of up to 1Gbps, 10Gbps than standard lights and colors currently available to improve the rate of increase, and the other is a channel such as a red LED, green LED is also a channel and so on.

Two other advantages of wireless optical communications, one from electromagnetic interference, although the current flight regulations allow passengers to use electronic products, and medical equipment in hospitals is important to use the room on the plane, are buried in the walls of the copper network in order to avoid interference from mobile phones, but there is still cause interference, in these sensitive sites use optical wireless communication, you can avoid interference.

Another is the power, the drive to pass the signal LED light off, more power than the RF radio frequency signal transmission mode, the handheld device battery power cable, optical wireless transmission would be more favorable. But optical wireless communication has its drawbacks, such as once shading can not receive, such as people walking, can not communicate through the wall, unless the wall can light.

Li-Fi direct vision combined with daylight plate LED bulbs, we can provide in-room wireless Internet HotSpot hot spots, while the phone more than a LED flash and CMOS camera lens, equivalent to already have the ability to close out of one, the future of inter-phone can easily pass information.

In addition to Li-Fi, the Japanese also developed indoor positioning IPS (Indoor Positioning System) with lighting, similar to Bluetooth Low Energy's Beacon indoor location, so you can be more energy-efficient.

Galaxy S6 Edge: Samsung released its own bending test

Samsung Electronics has provided an estimate for the first quarter of fiscal 2015 and contradicted a report on bent S6 smartphones. It is based on a continued decline in operating profit of 30 percent over the previous year - from 8.49 trillion won (7.17 billion euros) to 5.9 trillion won (5.0 billion euros). Consolidated sales decreased from 53.7 trillion won, up 12 percent to 47 trillion won. The final figures will report in late April.

Compared to the fourth quarter of 2014 with an operating profit of only 5.29 trillion won (4.47 billion euros) but an increase is visible, even though it is not possible Samsung to catch its decline from last year. For fiscal year 2014 had reported nearly a third less operating profit - due to the divisions Mobile and IT, with around 40 percent less profit for the year.

The only profitable division of Samsung was the semiconductor business, the profit is increased to 1.89 trillion won to 8.78 trillion won and its sales over the previous year increased by 6 percent to 39.73 trillion won last year. Its main customers were smartphone rival Apple, German Telekom, Ingram Micro, Sprint and Verizon, the relation of Samsung processors and components.

The success of Apple's iPhone models 6 and 6 Plus, the Samsung semiconductor manufacturing has, of course, also contributed significantly to the decline in Samsung's mobile division. Just last month it has with Galaxy S6 and S6 Edge introduced new devices.

These top models are viewing just like Apple's iPhone exposed 6 Plus at the start reproaches, they are easy to bend. The mobile insurer SquareTrade recently showed in a video that the Edge unlike other smartphones is bent at a force of 110 lbf (489 Newton) and his display breaks.

Samsung has now taken a position about this: A force of 110 lbf kick in practice hardly. In the back pocket of pressure lies much closer to 66 lbf (294 Newtons). In addition, internal tests had revealed that the Galaxy S6 and S6 Edge is not verbögen even at 79 lbf (351 Newtons). "This is so much pressure as you need to break five pencils at the same time."

In addition SquareTrade've only tested the stability of the front, criticized Samsung. Unlike many competitors, the new Samsung flagship models were equally stable backs. Its internal testing confirms that Samsung also with a video.
