Patent JP-2002026405-A (JP)
Title: Thermoelectric material, and method and device for manufacturing it
Inventor: NAKAHARA YASUO
IPC: H01L35/18
Filed: 2000-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoelectric material having high performance index. SOLUTION: A material is sealed up in a vessel (process S10), the sealed-up material is melted to form a BiTe alloy molten liquid (process S12), and the BiTe alloy molten liquid is rotated while cooled (process S14) to manufacture a thermoelectric material. Since the BiTe alloy molten liquid is cooled while shaken, the molten liquid coagulates with no stable liquid surface, thus crystal growth is suppressed. So average crystal grain size of the manufactured thermoelectric material is smaller. As a result, a phonon heat conductivity becomes lower, leading to a lower heat conductivity κ while smaller gap between crystal particles keeps electric conductivity σ high. As a result, a thermoelectric material of high performance index is manufactured.

Title: Method and system for optical transmission
Inventor: INOUE YASUSHI
IPC: H04B10/516
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To transmit a signal light by an optical polarization modulation system without requiring polarization control on a receiving side. SOLUTION: Signal light is obtained by performing optical polarization modulation for making polarization orthogonal to the polarizing state of light preceding by one bit when a transmission signal is '0' and making the same polarization as the polarizing state of light preceding just before by one bit when a transmission signal is '1' and is transmitted, and a received signal light is synthesized with the signal light preceding by one bit. In the case of mutually orthogonal polarization, they are outputted to two output ports without interference and when they are in the same polarizing state, they are outputted to one of the two output ports by interference. Then, the signals of the respective output ports are transduced to electric signals and the difference signals of both of them are outputted as a demodulation signal with respect to a transmission signal.
