Abstract: PROBLEM TO BE SOLVED: To provide a damping body which effectively uses rubber as a waste material at low cost, has no limit in size of the product, and is less deteriorated by crushing the rubber or forming it into chips, by aggregating them, and by wrapping the aggregate with a rubber layer. SOLUTION: Upper/lower metal molds are closed so as to form a hemispherical cavity, which is filled with mixed compound, the metal mold is heated to a set vulcanized temperature, the pressure is held as it is, and after the lapse of a prescribed time, a rubber hemisphere 28 as a vulcanized product is taken out from the metal mold. Secondly, a used tire is roughly crushed by a grinding mill and finely crushed by a refiner, so as to be waste rubber 32, which is conveyed by a belt conveyer and put in the rubber hemisphere 28. Two rubber hemispheres 28 are prepared, thin unvulcanized rubber is applied on the rubber hemisphere 28 edge, and left/right rubber hemisphere 28 are stacked together. The joint part is heated and completely joined together so as to be formed into a rubber spherical body 34.  There is no limit in the working size of the rubber spherical body 34 product and the used tire as a waste material can be effectively used so as to be a product eco-friendly to the global environment.

Title: Tracking servo controller
Inventor: ONUKI NOBUTAKA
IPC: G11B7/09
Filed: 1985-12-13
Abstract: PURPOSE:To speedily execute lead-in after 'out of track' and to stabilize tracking by inhibiting an optical beam from moving when the optical beam lies between tracks and when a tracking servo is inoperable. CONSTITUTION:A tracking error signal from a terminal 1 is supplied through a phase compensator 2, a loop switch 3 and an amplifier 5, and a tracking drive device coil 6 executes the tracking servo.

Title: Volume holograph diffuser
Inventor: TOMATSU PII JIYANSON
IPC: G02B5/32
Filed: 1991-10-01
Abstract: PURPOSE: To obtain a volume holograph diffusion body based on the speckle theory applicable to many applications. CONSTITUTION: This diffusion body 30 consists of a pure phase volume holograph medium. Diffusion boundaries smoothly changed in the refractive index are recorded on the medium. The optical path length of the light passing the medium is increased. The diffusion boundaries within the thick volume holograph medium have no boundaries or lines where the directions and intensity of the light passing the medium change drastically. The medium is acted like a GRIN medium by the smoothly changing boundaries or areas of the diffusion body 30 segmented by the smooth changes of the refractive index. Such effect of the medium is explained by using a GRIN model. The pure phase GRIN type medium diffuses all of the light projected to the medium and the projected light is eventually not sufficiently reflected.  Then, the light passing the volume holograph diffusion body 30 eventually traces the irregularly curved long optical passages and the diffusion characteristics are greatly improved.

Filed: 1989-10-28
Abstract: PURPOSE:To enable the amount of washing water in an outer tank accurately detectable even at the time of washing action with an inner tank rotated by sensing fluctuation of upper air pressure in a pressure generating pipe by fluctuation of its internal water level through a pressure sensor to detect the water level while arranging an outer tank side opening of the pressure generating pipe on a vertical surface or in its vicinity of passing through the center of rotation of the inner tank. CONSTITUTION:During washing action, pressure in an outer tank 15 is always detected by a pressure detecting device 106, but when washing water is absorbed by a excessive amount of wash and washing water becomes deficient, the pressure is decreased causing a pressure sensor 108 of the pressure detecting device 106 to be actuated, with washing water supplied. Now since an opening in a side of the outer tank 15 of a pressure generating pipe 107 is arranged in a vertical surface or in its vicinity of passing through the center of rotation X-X of an inner tank 30, even when it is rotated by an inner tank drive-rotating means 76 at the time of the washing action, the pressure can be almost accurately detected by the pressure generating pipe 107 because of minimum fluctuation of a water level Wn of the washing water.
