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 New Slide Switch Enabling Design of More Compact Electronic Devices by ALPS Electric
Market Demand for thinner and smaller form factor portable electronic devices has forced components manufacturers to come up with thinner components occupying a smaller footprint. This pressure has been felt more by manufacture of compact slide switches, components that are normally placed on the side of a device responsible for performing the ON/OFF power or performing hold (Pause) function. At the same time, overwhelming number of electronic devices such as smartphones with touch panel operation functionality have begun incorporating slide switches allowing easier visual confirmation from the mobile phone’s pause function. In response to this need Alps Electric has developed a 0.7mm-high slide switch in helping the mobile product manufacturers to design more compact electronic devices such as mobile phones, digital cameras and compact music players.

Development of New TACT Switch for Automobiles by ALPS Electric
Automobile manufacturers have increasing incorporated a variety of switching components on to the steering wheel of the vehicle rather than on the hard to reach instrument panels. This sort of design previously was primarily targeted at luxury automobiles, allowing the driver to directly operate on-board devices such as audio equipment and air-conditioning system. However, implementing switches into the steering wheel of a vehicle require a high operation force in order to prevent unintentional operation while driving, necessitating a need for a more define clicking sensation in such switching components. Based on this need, Alps Electric has developed new SKPR Series TACT Switch for automobiles, providing a more definite clicking sensation, due to its operating force of five newtons, plus an operating life of 100,000 cycles, capable of withstanding frequent usage over a long period of time.

Development of New Automobile Driving Simulator by HONDA Motor
Honda unveiled its all new and enhanced automobile driving simulator designed to help driver trainees to recognize and understand potential driving risks. The new enhancement in this newly developed driving simulator provides an easy to understand graphics and/or written descriptions of conditions where the driver must take caution. In addition to this, the new driving simulator offers advice on how to ensure safe driving in potentially dangerous situations which has a high probability of occurring in the real life. Read more
Development of New Bending Loss Insensitive Single Mode Optical Fiber by Sumitomo Electric
Sumitomo Electric made an announcement on development of PureAccess-R5, a bending loss insensitive single mode optical fiber that is fully compliant with the new ITU-T G.657.B3, a recommended standard for macrobend at a 5mm radius capable of efficiently routing optical drop cables as well as other applications inside the home and Multiple Dwelling Units (MDUs).

Development of New Photovoltaic Inverter Technology By MITSUBISHI ELECTRIC
The current photovoltaic (PV) system output power as well as other characteristics is increasingly influenced by the amount of sunlight plus temperature. In a conventional PV arrays, groups of PV modules are connected either in series or parallel, which utilize maximum power-point tracking (MPPT) system for assisting the PV systems to achieve their maximum output power points. However, in this system if part of a PV array is covered in shadow, while the rest of the array is still in sunlight would result in multiple peak points where conventional MPPT system has difficulty in tracking the maximum point. This could be a natural occurrence in urban areas where PV systems are likely to be installed near buildings or other sunlight obstructing objects, where shadow can greatly decrease output power of PV systems. In response to overcome this shortcoming by MPPT system, Mitsubishi Electric has developed a world’s first new photovoltaic inverter technology which is capable of maximizing output power in PV systems through incorporation of new MPPT system in PV inverters.

Development of New Nanostructure Fabric for Advanced Firefighting Suits
The two basic features in fire fighting suits are their flame and heat barrier properties and comfort to alleviate fatigue and heatstroke. Up to now, combining these at a high level has been technically challenging. In respond to meet this challenge, the New Energy and Industrial Technology Development Organization (NEDO), Teijin Techno Products Limited and Hosokawa Micron Corporation made a joint announcement on development of a new fabric incorporating nanostructure fiber targeted to be used in advanced firefighting suits which are expected to be 40% more effective in preventing burns in comparison to fabric with no nanostructure fiber, and 15% lighter than conventional heat-barrier linings. The nanostructure fiber is made through kneading of nanosized carbon particles into Technora Fiber, a Teijin Techno Products’ high performance para-aramid fiber offering high strength, heat resistance with dimensional stability and chemical resistance.

Development of New AZ91 Magnesium Alloy Sheet by SUMITOMO Electric Industries
Magnesium, among the metal in use is the lightest, with specific gravity lower than quarter of iron and around two third of aluminum. Furthermore, it features an outstanding strength and rigidity per weight in comparison to iron and aluminum contributing in manufacturing strong and light products. Adding to this, the magnesium is considered to be an environmentally friendly metal due to its high energy efficiency and recyclable properties, not to forget its abundance in nature. Based on these properties , Sumitomo Electric has developed AZ91 magnesium alloy sheet and its commercial production through a unique continuous casting process for the first time in the world.
