Development of a Breakthrough Technology for Achieving Low Voltage Operation in System LSI by TOSHIBA
System LSI constitute the core components of digital products, where their operation voltage has a major impact on an overall power consumption of a product. However, up to now, voltage scaling of cutting edge system LSI has presented a big technological challenge due to loss of stability in memory function of its embedded SRAM which occurs at low voltage. The smaller size of the memory cell transistor of SRAM makes SRAM susceptible to transistor variability at low voltage in comparison to other logic circuits. In order to overcome this issue, Toshiba has developed a SRAM circuit technique which results in a low voltage operation in system LSI, paving the way in reduced power consumption in digital products.

Development of Millimeter-Wave Intra-connection Wireless Technology by SONY
Millimeter waves are electromagnetic waves with a frequency range of between 30GHz to 300GHz, and wavelength between 1mm to 10mm. With their inherent high frequency, millimeter waves are best suited for ultra high speed data transfer. Their advantage goes further through their ability of transferring data in such high speed with use of very small antennas. With today’s multi-functional electronic equipments there is an increasing amount of internal data transfer which wired connected approach will soon its limit in data capacity, requiring an additional circuitry to accommodate a larger data transfers, however this approach will result in increasingly complex IC packages, intricately printed circuit boards not to mention a larger IC sizes. Millimeter wireless technology offers a promising choice in fulfilling this need. Base on this technology and in the face of coming shortage in data capacity, Sony made an announcement on development of millimeter wave wireless intra-connection technology capable of high speed wireless data transfer inside electronic products such as television sets.

Development of a Method for High Purity Separation of SWCNT by AIST
Carbon nanotubes (CNTs) come in two main forms,one being the single-walled carbon nanotubes (SWCNT) and the other is the multi-walled nanotubes (MWCNT). The structure of a SWCNT is a one-atom-thick layer of graphite which is called graphene, wrapped into a seamless cylinder with open or closed ends. Depending on the arrangement of the carbon atoms, SWCNT exhibits metallic or semiconducting properties. Normally, the synthesis of SWCNTs yields a mixture of these two types. However, if the these two types can be separated in high purity, they can be utilized in many potential applications. For instance, metallic SWCNTs can be used as transparent electrodes in production of liquid crystal displays or solar cells instead of the transparent conductive materials which is prepared using rare metals, also the metallic SWCNTs can be used in wiring ,in development of high-integration high-speed SWCNT computers. On the other hand semiconducting SWCNT can be employed as transparent and flexible transistors. Read more

Thermoelectric Power Generation Based on Waste Heat
Conversion of heat energy into electricity is based on electric potential difference which is caused by temperature differences at both sides of thermoelectric elements. Around 70% of total energy provided in Japan is wasted through its emission into the atmosphere, making thermoelectric power generation a viable method for utilization of this vast untapped energy coming form different sources, including incinerators, automobiles, ships and industrial equipment, while at the same time it will contribute in reduction of CO2 emission. Up to now, development of thermoelectric power generation has been done on the low temperature range between 100 to 300 degrees Celsius involving hot springs and diesel engines. Based on this, Showa Denko (SDK) and Plantec have made an announcement on full scale demonstration of thermoelectric power generation based on waste heat using SDK thermoelectric conversion modules in a waste incinerator built by Plantec.

Achievement of World’s Highest Areal Density on Linear Magnetic Tap
An increase in worldwide data storage volume, forcing the manufacturers in producing larger capacity data storage media. But in order to increase the storage volume of magnetic tape storage media, it is necessary to micrify the particle size and increase the recording density. However, this procedure is extremely cumbersome using metal particle as one of the most popular material among the magnetic tape media market, all due to keeping the high coercivity for high density recording. Based on this challenge, Fujifilm has developed BaFe (Barium Ferrite) particles in achieving the world’s highest areal density of 29.5 billion bits per square inch on linear magnetic tape ,paving the way in manufacturing a 35 terabytes of data capacity per cartridge , 44 times the data capacity of today’s industry magnetic tape product.

Development of Highly Sensitive Fluorescent Based Stree Assessment System by ASIT
In spite of mental stress being a major issue in today’s social environment, there is yet an established system for assessing stress objectively. One approach in measuring individual’ stress level is through measurement of levels of stress related substances. One such substances that is closely related to stress is catecholamines ,which is present in blood and urine. Based on this fact AIST has successfully developed a highly sensitive fluorescent based detection of catecholamines as stress markers. Through this development AIST has chemically modified the surface of the glass substrate with probe molecules which bonds chemically with catecholamines to form a fluorescent complex. Read more
