No. 144: Bioresin without food materials from NEC (August 26, 2010)

NEC, one of Japan’s electronics giants, developed bioresin that does not contain food materials. More than 70% of the newly-developed resin is the material made from rice straw and cashew nut husk. The company successfully developed the new resin by synthesizing chemically cellulose made of plant haulm like rice straw and oily material extracted from cashew nut, and secured enough strength, heat resistance, and water resistance to be used for PCs. A bioresin usually needs petroleum components to increase strength, but the new bioresin reduced the ratio of petroleum components to less than 30%. And it is totally free from food materials. Actually, it is the first bioresin of this kind. The existing bioresin uses corn-derived materials. This bioresin can enjoy stable supply of raw materials because more than two billion tons of materials for cellulose and more than one million tons of cashew nut husks are disposed annually. The company is working on mass production technology to use this resin for its PCs toward 2013.

No. 143: Chip to reduce the power consumption of an LSI considerably (August 25, 2010)

Tokyo University, Pioneer, and Toshiba successfully developed the next-generation chip that reduces LSI’s power consumption to one ten thousandth of the current level. The new technology trades data by light instead of electrons because light has less power attenuation. They built the key component that processes optical data moving inside the element at high speed on trial. An LSI that processes data only by light can be built by combining the newly-developed amplifying element with wiring. Because light has extremely smaller resistance than an electron when it runs in wiring, it can reduce energy loss considerably. This is the achievement of a project conducted by NEDO. The project succeeded in the experiment to create special light called near-field light inside the element by irradiating the element with light that flashes 80 million times per second and gate the light’s passage in accordance with the flash of the light. The technology is scheduled to be put into practical use around 2020.
