Title: Disc brake protector device
Inventor: WATANABE SHOEI
IPC: B62J23/00
Filed: 1989-04-14
Abstract: PURPOSE:To improve removing performance by forming the periphery of a plate like protector fixed at a caliper bracket slightly more protrusive in the radial direction than a brake disc, thereby unnecessitating the removal of the protector at the time of removing a wheel. CONSTITUTION:The hub 14 of a rear wheel is rotatably held at an axle 12 pierced in a rear arm 10 as well as the collar 18 of a caliper bracket 16 is mounted thereon. A plate like protector 36 is fixed at the caliper bracket 16 by a bolt in such a way as to face the outer surface of a brake dic 30 with a narrow space in the axial direction, and its periphery is formed to be slightly more protrusive in the radial direction than the lower edge of the brake disc 30. Accordingly, even if there is an obstacle on the road surface during running, the obstacle hits against the protector 36 more protrusive than the brake disc 30, so that the brake disc 30 is prevented from being damaged. In addition, the brake disc 30 does not interfere with the protector 36 at the time of removing the rear wheel as it is not radially covered by the protector 36, thereby facilitating the removal of the rear wheel.

Title: Prosess of molding base plate of optical disk
Inventor: INOTSUKA AKIHIRO
IPC: B29C45/17
Filed: 1986-04-24
Abstract: PURPOSE:To obtain a base plate of optical disk having a high CN ratio, by molding a resin by means of injection molding while an ultrasonic wave is being applied to the resin in a molding cavity. CONSTITUTION:An ultrasonic wave oscillator 2 is operated just after a resin is injected in a molding cavity 13 and is stopped when the resin substantially solidifies. As the resin, all the resins showing refractive index anisotropy can be used, but polycarbonate resin is effective because of the balance of its other characteristics. In general, an ultrasonic wave vibration is applied to a polymeric substance in its molten state, i.e. above its glass transition temp., sliding diffusion and segmental movement of the molecular chains and dispersion of the side chains are induced. By giving activation energies to be necessary for these molecular relaxations by means of the ultrasonic wave vibration and by relaxing the molecular orientation which has occurred when the resin is poured at an ultrahigh speed into a flat cavity by means of injection, the double refraction can be reduced and the CN ratio can be improved.

Title: Nonshort break amplifying circuit
Inventor: SAKUYAMA ISAO
IPC: H03F1/34
Filed: 1979-07-23
Abstract: PURPOSE:To stabilize the level by absorbing the amplification component of the main feedback which increases when the single connection of the amplifying part shifts to the parallel connection by securing formation of the local feedback loop when the parallel connection is given among the amplifiers. CONSTITUTION:The nonshort break circuit which gives the switching between two amplifying parts 3 and 3' via input coupling circuit 2 and output coupling circuit 4. In such circuit, local feedback circuit 8 is provided to secure the local feedback from the output side of part 3 to the input side of part 3' only in case the parallel connection is given to both parts 3 and 3'. Thus the gain increment component can be absorbed when the parallel connection is given between parts 3 and 3' by setting properly feedback circuit 8. As a result, the amplifying circuit can be used in a steady condition with both the parallel connection and the single connection.

Title: Automatic pressure regulating valve
Inventor: MORITA HIROSHI
IPC: G05D16/16
Filed: 1978-07-31
Abstract: PURPOSE: To prevent leakage of water from pipings of waterworks or other, by connecting a plurality of pilot valves having different set pressure to a pressure regulating valve arranged in a water supplying conduit and switching use of these pilot valves selectively depending on the amount of water being supplied through the conduit.  
     CONSTITUTION: Pilot valves P 1 , P 2  having different set pressure are connected respectively in parallel conduits 11, 12, 20 and 11, 13, 20 extended from valve chamber 6 to the secondary side 3 of valve body 1. When amount of water used is reduced, pressure in conduit 10 is increased, whereby diaphragm (d) of switching pilot valve C is pushed upward and the valve opening is closed by valve element (e). Resultantly, pilot valve P 1  having a higher set pressure than pilot valve P 2  becomes inoperative, whereas another pilot valve P 2  having a lower set pressure is set into operation, so that pressure at the secondary side 3 is maintained at a low level. Therefore, reducion in the amount of water used does not cause pressure rise of water supplied through the main water supplying pipe, so that leakage of water can be prevented. When amount of water used is increased, on the other hand, pilot valve P 1  is in turn set into operation, and water pressure corresponding to the increase in the amount of used water can be maintained in the pipe.
