Title: Method for restoring function of light guide for device for detecting oil leakage
Inventor: KOJIMA TAKESHI
IPC: G01M3/18
Filed: 1983-03-23
Abstract: PURPOSE:To remove oil permeating the inside of the clad of a light guide without cutting off the part of the guide swollen with the oil by immersing the swollen part in an org. solvent having compatibility with oil to be detected and high volatility for a prescribed time. CONSTITUTION:An org. solvent having compatibility with oil to be detected and high volatility and not swelling the clad of a light guide is used. When the clad is made of silicone resin and oil to be detected is synthetic insulating oil such as alkylbenzene applied usually to an OF cable, alcohol or acetone is suitably used. A light guide is preferably immersed in said org. solvent for 1-2hr, yet when the guide is repeatedly immersed in the solvent and allowed to stand in the air to evaporate the solvent several times, immersion for <1hr can produce a sufficient effect. It is not necessarily required to immerse the whole light guide, and when the part of the clad swollen with oil is detected, only the part may be immersed.

Filed: 1994-03-18
Abstract: PURPOSE:To obtain a Fresnel optical element which can prevent a ghost image from being formed and is easily manufactured by forming plural beltlike prisms and making the beltlike prisms different in the tilt angle of step surfaces to a reference surface from one another. CONSTITUTION:The Fresnel lens 10 is constituted by forming annular lenses 11A-11E concentrically with one another and connecting the annular lenses 11A and 11B, 11B and 11C, 11C and 11D, and 11D and 11E by step surfaces 12A-12C and 12D.

Title: Oil hydraulic buffer
Inventor: SUKA TEIJI
IPC: F16F9/348
Filed: 1979-04-23
Abstract: PURPOSE:To prevent generation of abnormal sound in an oil hydraulic buffer for the suspension of a vehicle such as an motorbicycle by providing a disc valve which is opened and closed in accordance with the direction of movement of a piston with oil holes and providing the valve with a close contact prevention serration. CONSTITUTION:A valve sheat 13 is provided with a number of radially spaced peripheral notches 21. When the compression stroke of this oil hydraulic buffer is changed to the extension stroke, a negative pressure is produced within the inner cylinder 2, so that a check valve 16 and a disc valve 14 are upwardly displaced in the Figure against the spring force of a spring 20 to open an oil port 8. At this time, if the valve 14 and seat 13 are brought into contact over a wide area, even very fine gaps between the two surfaces in close contact are filled with oil, so that they will not be readily separated. Since the area of close contact is reduced by the provision of the serration, the attracting force is reduced, and thus with an increase of the negative pressure within the inner cylinder 2 beyond the spring force of the spring 20 the valve 14 is immediately separated from the seat 13 and raised at a slow speed by compressing the spring 20. Thus, it is prevented from striking a stepped portion 23 with a great momentum. In this way, abnormal sound can be prevented.
