Title: Pneumatic pressure control valve for air clutch
Inventor: MURAKAMI KIYOJI
IPC: F16D25/08
Filed: 1987-03-02
Abstract: PURPOSE:To facilitate clutch operation, by constructing a pneumatic pressure control valve for an air clutch such that an air pressure characteristic for clutch control is obtained at a piston position slidable through hydraulic pressure fed from a clutch master cylinder interlocked with a clutch pedal, thereby making the control valve mountable onto a vehicle having a normal master cylinder. CONSTITUTION:When the hydraulic force functioning onto a piston 72 increases through stepping operation of a clutch pedal 57, energizing force of first rod 75 with respect to a second valve body 63 weakens to lower the pneumatic pressure for an air clutch gradually and an air pressure characteristic proper for control of air clutch can be obtained. Consequently, a pneumatic control valve for air clutch can be mounted as it is onto a vehicle having a normal master cylinder 58 without requiring conventional connection with a clutch pedal 57 through the rod. Furthermore, abrupt connection/disconnection of clutch through slight stroke of clutch pedal 57 can be prevented, resulting in facilitation of clutch operation.

Title: Side impact air bag device for motor vehicle
Inventor: KURATA HIDENORI
IPC: B60R21/20
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To degrade the material specification and to improve the expansion speed of a breast protecting part by providing, within the breast protecting part of an air bag, an auxiliary air bag of a form substantially similar figure to the breast protecting part and smaller than the breast protecting part, having a gas outlet port on the heat protecting part side. SOLUTION: A gas G blown out by operating an inflator by the side impact of a vehicle first expands an auxiliary air bag 9. Its volume is smaller than a breast protecting part 7 with a higher expanding speed, and the breast protecting part 7 of an air bag 3 is also expanded at a high speed in interlocking therewith and developed in a narrow space between an occupant breast and the vehicle body side wall. The gas G is blown out to a head protecting part 8 through an outlet port 12 at the tip of the auxiliary air bag 9 to expand the head protecting part 8 upward and finally expand the breast protecting part 8 around the auxiliary air bag 9.  Since the thermal and pressure load of the blown gas G is once received by the auxiliary air bag 9 and moderated, a heat resisting and pressure resisting material is required only for the auxiliary air bag 9, and the specification of the large air bag can be degraded, and the expanding speed of the breast protecting part 8 interlocked with the auxiliary air bag 9 can also be improved.

Title: Adhesive composition used in sticking thin sliced veneer
Inventor: HASEGAWA MASANOBU
IPC: C09J11/04
Filed: 1979-04-19
Abstract: PURPOSE: To obtain an adhesive used in sticking thin sliced veneer, which is free from problems of exudation and reduction in productivity, by adding inorganic fine powder to a mixed paste obtained by adding a filler to an aqueous resin adhesive.  
     CONSTITUTION: To a mixed paste prepared by adding a filler, such as wheat flour or soybean powder, to an aqueous resin adhesive such as a urea resin, a melamine resin, a vinyl acetate emulsion, or an SBR latex, is added 0.1W10% of inorganic fine powder, particle diameter ≤0.1μ, such as fine silicic acid powder, light calcium carbonate, clay or magnesium carbonate. As said inorganic fine powder, fine silicic acid powder, particle diameter ≤0.05μ, which, in a small amount, shows a thickening effect, is particularly preferred. The amount of the inorganic fine powder added depends on the particle diameter, oil absorptivity, etc. When the fine silicic acid powder, particle diameter ≤0.05μ, is used, the amount added is preferably 0.1W 10%, based on the mixed paste, and the addition of more than 10% does not bring about an additional effect, but adversely effects the adhesiveness.

Title: Device for feeding coil spring in line
Inventor: YOSHIKAWA TOYOJI
IPC: B65G47/14
Filed: 1988-03-01
Abstract: PURPOSE:To make it possible to automatically feed each coil spring in line, which is thin in wire diameter with a wide, by forming the bowl bottom surface of an electromagnetic oscillation type part feeder into a conical surface with a steep slant in such a way that selected or excluded coil springs are directly returned back to a separation feeding means. CONSTITUTION:The bowl 4 of an electromagnetic oscillation type part feeder 5 is formed into a conical surface with a steep slant at the bottom surface 4a of it, and the terminal end section of it is connected with a track 4b. When a coil spring falls down, it stands automatically in the track carrying direction so as to be lined up over the track. There will hardly be any chance therefore for the coil spring to come in contact with each other while getting entangled so that each coil spring is lined up on the track. In the second place, coil springs excluded from the surface of the track by means of both a selection gate 4c and over-flow fall down into a housing section 4d provided for the upper outer side of the bowl 4 so as to be returned back to the spring accelerating means 2 of a spring separation feeding means 1 by a returning means 6. There will never be any chance therefore for the abovesaid springs to be entangled with the coil spring within the bowl, the coil spring which is thin in wire diameter with a wide pitch is thereby also automatically fed while being lined up.
