Patent JP-H02138543-A (JP)
Title: Chain tensioner
Inventor: YAMADA SEIICHIRO
IPC: F16H7/08
Filed: 1988-11-18
Abstract: PURPOSE:To positively prevent a rod from retreating by providing a fine gap halfway the distance to the ratchet teeth of the rod in proximity to the ratchet teeth of a cam. CONSTITUTION:A fine gap delta is provided halfway the distance to the ratchet teeth 5 of a rod 4 on the upstream side of a ratchet teeth 9 in proximity to the ratchet teeth 9 of a cam 7, that is, toward the energizing direction of the cam 7 (direction (b) as indicated by an arrow head) so that a circular arc section 7a is formed. Which causes the circular arc section 7a to come in contact with the ratchet teeth 5 so as to minimize the rotation of the rod 4 around a shaft center. The situation permits the respective ratchet teeth 5 and 9 to be positively engaged with each other while covering the whole width at all times even when the respective ratchet teeth 5 and 9 of the rod 4 and the cam 7 are engaged with each other only at their apexes, thereby positively preventing the rod 4 from retreating (movement against the energizing direction).

Title: Amorphous silicon solar cell
Inventor: MORIUCHI SOTA
IPC: H01L31/04
Filed: 1989-11-08
Abstract: PURPOSE:To assure a high photoelectric conversion efficiency, preventing characteristics from being deteriorated owing to accumulated light irradiation by depositing a plurality of amorphous silicon layers forming a PIN junction or the surface of a columnar Si crystal grown vertically spaced away from each other in the form of corrugation. CONSTITUTION:A title cell comprises a 0.01mum-1mum diameter columnar Si crystal 3 grown on a substrate 1 vertically to a substrate 1 surface, and spaced away at a distance of 1mum or less on the surface, and a plurality of amorphous silicon layers 5, 6, 7 deposited on the surfaces of the substrate 1 and on a surface of the columnar Si crystal 3 and corrugated in their vertical sections, the layers 5, 6, 7 forming a PIN junction. In this case, light vertically incident on the substrate or parallel incident on the columnar Si crystal is absorbed in a big volume by an I-type layer 6 thick in the direction of the columnar Si crystal to produce many carriers. Additionally, since the I-type layer is thinner in the radial direction, a distance which the carriers require for their travelling is reduced and an internal field is less weakened. Hereby, a photoelectric conversion efficiency and a filling factor are increased, and any deterioration by the light is reduced.
