A New Rolling process for Manufacture of AZ31 Magnesium Alloy by AIST
Magnesium alloys are inherently light weight structural materials, all due to their high specific strength, high specific stiffness, and not to forget their abundance of resources. Their utilization is expanding into areas of automobiles and consumer electronics industries such as laptop PC and mobile phones, however, rolled magnesium alloy sheets exhibit poor room temperature formability, forcing the press-forming process to be carried out at an elevated temperature above 250 degrees Celsius, where installation of additional equipment for heating the magnesium sheet and dies are required, resulting in significant cost increase in manufacturing. In response to lowering manufacturing cost of magnesium alloy sheet, AIST (Advanced Industrial Science and Technology) in Japan has developed a new rolling process for commercial magnesium alloy sheet with high room temperature formability.

Development of 16:3-aspect, 19.2-inch Color TFT LCD Module by Mitsubishi Electric
Mitsubishi Electric made an announcement on development of 19.2-inch TFT-LCD module with 16:3-aspect, designed to enable a broad range of display and design solution for wider-format module such as kiosk display, information monitors, gaming and other entertainment applications. The new model, AA192AA01 comes in a form factor of 496.5mm (W) x 109.2mm (H) for the display of 16:3 ratio images (1920 x 360) pixels. Furthermore, the incorporation of white LEDs has allowed the newly developed module to achieve a minimum backlight lifespan of 60,000 hours at the room temperature (25 degrees Celsius). Read more
Development of Industry’s First 0.9V Drive MOSFETs for Mobile Devices by ROHM
Rohm made an announcement on development of industry’s first 0.9V type MOSFETs as part of expanding company’s ECOMOS series of low voltage drive. The newly developed drive is targeted for mobile devices such as portable audio, IC recorders, electronic dictionaries, portable radios as well as electronic toys to name a few. Rohm through development of this MOSFET has succeeded to control current leakage by optimizing the MOSFET gate layer and the channel profile making the 0.9V drive with a stable OFF state, enabling operation using only a single dry-cell (1.2V, termination voltage 0.9V) without requiring a step-up circuit, resulting in smaller, lighter sets with fewer external parts.

Development of New Optical Transmission Devices in Compliance with IEEE 100GbE standard by Mitsubishi Electric
Today Mitsubishi Electric unveiled two new optical transmission devices capable of multiplexing four wavelength channels of 25 Gbps speed optical signals in parallel. The transmitter module responsible for sending optical signals comes with a high speed direct modulation distributed feed back (DFB) laser diode and it features modulated waveforms of 25 Gbps. The receiver module has been incorporated with photo diode array, has a leading-edge responsivity of 0.88 amperes per watt (A/W). In spite of strong demand for 25 Gbps DFB laser diode capable of operating directly by modulating signals without any requirement for external modulation devices, however, development of such device faces some difficulty due to decrease in mask margin ,an index that shows the quality of modulation waveform (eye diagram). To overcome this issue, Mitsubishi’s newly developed laser diode active layer, where laser beams are made, has been incorporated with buried active layer structure using AlGalnAs. Furthermore, the laser diode has an active layer with a short cavity, and by keeping down the density of the operational current plus by inhabiting the electrons in the active layer, Mitsubishi Electric has successfully achieved low energy consumption and high level of quality in eye diagrams.

Development of Diamond based LED with Improved Output Power for Sterilization of Viruses by AIST
With increase in epidemic diseases caused by viruses such as H1N1 at a global level sterilization is becoming a critical necessity for society in their daily life. Up to now, sterilization has been carried out using heat, chemicals and UV light, where UV light posses many advantages such as being effective against thermotolerent bacteria, while not having any adverse chemical effects, and at the same time it directly acts on the bacterial DNA to inhibit the viruses proliferation. In this case, light with wavelength of around 260nm at which DNA absorbs light is capable of significantly sterilizing bacterial. Currently, mercury lamps that emits 254 nm UV light are being used to fulfill this task, however use of mercury in these lamps make them environmentally unfriendly, leaving researchers and manufacturers alike to develop semiconductor LEDs in achieving this task. So far, the development of UV LEDs has been focused in using LEDs that are composed of widely used gallium nitride, but the use of this material will make it difficult to fabricate LEDs capable of emitting light of shorter wavelengths. For this reason LEDs that emit light of wavelength 350 nm or shorter are not available commercially. Read more
Development of 2-Wavelength Laser Diodes with Significantly Lower Operating Current by ROHM
Laser guides are typically come in to types, one is the Loss Guides and the other is Real Index Guides. In spite of being simple and inexpensive, the Loss Guides have a tendency to absorb light within the device during laser oscillation besides showing unstable at high temperatures. On the other hand, Real Index Guides provide a stable operation with no light absorption, but their manufacturing process is complex and the production cost is high, limiting them to be only utilized as high output lasers. In response to this limitation, Rohm has succeeded in developing a highly reliable 2-wavelength laser targeted for low output applications such as DVD/CD playback by using an optimized, highly efficient Real Index Guide with no light absorption loss.
