Title: Hydraulic shock absorber
Inventor: TOIYAMA YOSHIRO
IPC: F16F9/32
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To realize a simple processing and to solve a bad influence to a piston ring by constituting a by-path communicating both upper and lower oil chambers partitioned by a piston by a concave portion communicating both upper and lower apertures provided on a cylinder and a cylinder press-fitted to an outer periphery of the cylinder so as to hide the concave portion. SOLUTION: A by-path L is constituted by both upper and lower apertures 12, 13 provided on a cylinder 1; a concave portion 14 communicating them; and a cylinder 4 hiding the concave portion 14. In the case where a hydraulic shock absorber exceeds a ride-on stopping state and is expanded and shrunk when a motor-bicycle travels on a bad road, both upper and lower apertures 12, 13 are set such that a piston 2 sliding in the cylinder 1 does not interfere. Accordingly, a piston ring 23 at an outer periphery of the piston 2 is positioned between both upper and lower apertures 12, 13 so long as the motor-bicycle travels on a good road. As a result, since the piston ring 23 does not contact with both upper and lower apertures 12, 13, it can be avoided that a deviation abrasion and an abnormal abrasion are generated on the piston ring 23.

Title: Optical information recording medium and its production
Inventor: KOMORI TETSUO
IPC: G11B7/24033
Filed: 1987-12-23
Abstract: PURPOSE:To obtain a recording medium which allows recording of optical information of a laser, etc., and is usable as a master plate of an optical card by providing fine ruggedness to the surface of patterned electrodes and an electrolytic polymer layer of pyrrole formed on the electrode surface. CONSTITUTION:A nonaq. electrolyte contg. pyrrole is brought into contact with the patterned electrodes to coat the electrodes with the polypyrrole of the roughened surface state by anodic oxidation. Transparent electrodes consisting of ITO films or metallic electrodes consisting of platinum, etc., are preferably used for the electrodes. The surfaces of the electrodes may be patterned by photoetching or screen printing at need before said surfaces are electrolyzed. The electrolytic stage can be executed by immersing the electrodes into the electrolyte and impressing a voltage between the electrodes, thereby effecting the constant potential or constant current electrolysis of the electrolyte. This optical information recording medium records the optical information of the laser, etc., and serves as the master plate of the optical card; in addition, the medium is usable as a photoelectric transducer as well. The surface roughening in this production process is automatically executed in a stage for forming the high-polymer film, by which the production process is simplified.
