This modulation device controls the phase of light by using light based on a new principle. Read more
Development of High-Speed Anonymous Authentication Circuit System by NEC
Secure authentication using digital signature is conducted throughout a wide variety of network equipment, including terminals and servers by ensuring each individual is identified in every transaction. However, use of this technology in a cloud environment, requires logging and storage of large amount of personal information on the cloud servers, with potential treat to privacy of users. Implementing a technology that posses a high processing speed to hand a large number of authentication request in a cloud environment without identifying individuals is a daunting task. In response to this challenge, NEC has developed a circuit system capable of processing large amounts of anonymous authentication transactions at a high speed while consuming a low amount of power by protecting both security and privacy of individuals.

World’s first Multi-Touch Controller for Resistive Type Touchscreens
Increasing number of screens panels in various consumer electronics are touchscreen panels, which has been driven with increasing functionality and sophistication of electronic devices, where operation of touch panels is increasing shifting toward pinch, spread and other intuitive finger gestures. UP to now, the only way to make this happen was through use of more expensive electrostatic capacitance type touchscreens which require certain input devices. Now, in order to give the same type of multi-touch (two-point) capabilities and intuitive gesture control, including pinching, spreading and rotating to resistive-type touchscreen due to their low cost, Rohm has developed industry’s first multi-touch controller for resistive touchscreens.

High-Speed Optical-Fiber Transmission Employing Uncooled Directly-Modulated Laser by Fujitsu
Fujitsu has recently announced the successful 40 Gbps optical fiber transmission using directly-modulated laser which does not require any cooling. This achievement was as a result of using combination of structure that is specifically configured to high-speed operation and a newly developed structure capable of lowering operating current as well as high-temperature operation. The new technology achieves a power consumption that is half that of commercialized 40-Gbps optical transmitters. Read more
Development of High-Speed Multi-Channel Transceiver Circuit, Capable of Extending In-Server Data Transmission Distances by Fujitsu
Fujitsu has successfully developed a high speed multi-channel transceiver circuit which operates at 10 Gbps. The new transceiver would help in extending the in-server data transmission distances by a factor of 1.7 times in comparison to commercially available technologies. The new transceiver would be used as backplane serving as communication channel within multi-process servers that combines multiple CPUs for achieving higher performance. This new technology would compensate for data signal distortion which is evident when the channels are extended. The new technology would extend the current distance from 70 cm to 120 cm, contributing to form large scale high performance server systems which connects far more processors that was previously possible.

Development of New Gear Cutting Machine by Mitsubishi Heavy Industry
Demand for high efficiency and accuracy equipment for machining of various gears including transmission gears, at low cost has been increasing in the automobile industry. Mitsubishi Heavy Industry (MHI) with its world’s first dry cutting gear production system using no cutting fluid back in 1997, has led the industry with diverse gear cutting machines and cutting tools. IN response to market demand, MHI has introduced a new gear grinding machines suitable for volume production of gears for up to 150 mm in diameter. The new ZE15B gear grinding machine is equipped with a newly developed workpiece changer resulting in shorter amount of time required for changeover, plus the twin tailstock model is capable of reducing non-operational time to just five seconds. The shorter high efficiency grinding has been achieved through an increase in machine rigidity and by adopting a 30 percent faster grinding wheel with the speed of maximum 6000rpm. Read more
Release of Large Capacity, High Speed, Low Power Consumption and Low Latency DRAM by RENESAS Electronics
