Title: Amorphous silicon solar battery
Inventor: MIYADO TOSHIO
IPC: H01L31/04
Filed: 1983-04-08
Abstract: PURPOSE:To enable to obtain a large short circuit current and a high conversion efficiency by making the surface of a transparent conductive film in uneven form, and the thickness of an I-layer within a fixed range. CONSTITUTION:The transparent conductive film constructed on the side of light incident of an amorphous Si semiconductor layer is formed of crystals of the average grain diameter 0.1-0.9mum. Then, said semiconductor layer whose thickness of the I-layer is 0.2-0.4mum is formed on said film. Such formation produces the uneven form of said film. Accordingly, the light wherewith the solar battery is irradiated vertically is refracted on each layer and obliquely advances through the I-layer. It causes to lengthen the light path in the I-layer, making the light absorbable even in a long wavelength. Further, the light reflected on the back surface electrode is reflected again on the unevenness of the surface of said film and turned back to the semiconductor layer and absorbed thereto. This manner enables to make the I-layer thin, by making said layer thin, not only the conversion efficency increases, but the deterioration of light can be inhibited.

Title: Method for winding tape to optical fiber core
Inventor: GOMYO HIROSHI
IPC: G02B6/44
Filed: 1987-03-17
Abstract: PURPOSE:To increase a taping speed and to satisfactorily maintain transmission characteristics by previously twisting an optical fiber core in a tape winding direction, winding the tape to the core in this twisted state and untwisting the core. CONSTITUTION:The twist-rotating speed of an endless track type take off 4 for forward rotation and an endless track type take off 5 for backward rotation provided between endless track type take off machines 2 and 3 are so adjusted that the max. twist strain of the optical fiber core 1 between the take off machines 4 and 5 is kept below the permissible twist strain of the core. The core 1 is untwisted and the helix angle thereof is decreased to zero during the time when the taped core 1 passes the take off 5 at the time of winding the tape 61 at a high speed on the core 1 in the same direction as the twist direction of the core 1. The side pressure by the tape winding is thereby sufficiently lowered in spite of the high speed taping under high tension. The taped optical fiber core is thus produced at a high speed while the transmission characteristic of the optical fiber is maintained.

Title: Angular velocity sensor
Inventor: YOSHINO SHIYOUGO
IPC: G01C19/5769
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a capacitance type angular velocity sensor having a high detection accuracy and a little sensitivity variation. SOLUTION: An angular velocity sensor 1 has a sensor element 10 and a support board 2. The board 2 has four through-grooves 6 around the sensor element 10 mounted on the board 2 surface so as to surround this element 10 in square. The grooves 6 function as means for preventing a deformation stress such as bending and twist of the support board 2 due to the working environment change or external forces such as shocks and vibrations exerted on the angular velocity sensor 1 from propagating to the mounted part of the sensor element 10. When the support board 2 is deformed, the deformation such as bending is approximately completely absorbed by portions where the grooves 6 exist because of the through-grooves 6, resulting in a structure wherein the deformation stress never propagates to the mounted part of the sensor element 10.
