Title: Check valve
Inventor: SHIMIZU YASUO
IPC: F16K15/02
Filed: 1982-03-11
Abstract: PURPOSE:To enhance operating characteristics of the titled valve and prevent chattering, by a construction wherein the area of a pressure-receiving surface is enlarged when a valve body is slightly spaced from a sealing surface. CONSTITUTION:An elastic packing 7 provided with an annular peripheral wall 7a having a diameter smaller than that of a piston 6 is fixed to an upper end surface of the piston 6. When a fluid at an inflow hole 3 exerts a pressure on the interior of the peripheral wall 7a of the packing 7 and the pressure overcomes the force of a spring 8, the piston 6 is slightly moved downwards, and at the  moment when the packing 7 is separated from a cap body 4, the fluid pressure  is exerted on the entire body of the piston 6, so that the piston 6 is rapidly  brought into close contact with a lower surface part of a cylinder, thereby setting the check valve 1 to the opened condition.

Title: Rotary electric machine
Inventor: NAGAYAMA TAKASHI
IPC: H02K5/06
Filed: 1985-02-28
Abstract: PURPOSE:To reduce the size and weight of a rotary electric machine by deleting an unnecessary portion of a large frame for coating the entire outer periphery. CONSTITUTION:Since holes A are formed at the peripheral surfaces of outer end frames 32a, 32b extended from both end core retainers 30 of a stator core 1, a worker can bind a coil end 5a through a binding ring 7 by an insulating string 8 by extending his hands from the hole A at the state that the hole A is not blocked by a cover 34. Accordingly, the binding fixing work of the end 5a can be readily and simply performed. After this work, the cover 34 is mounted to open the hole A. Then, a stator core assembly can be obtained. If a rotary electric machine is thus assembled, the size and the weight can be reduced, the characteristics and speed can be improved to contribute to an energy-saving due to reduction in the weight.

Title: Lockup device of torque converter
Inventor: MATSUOKA YOSHIHIRO
IPC: F16H45/02
Filed: 1992-02-26
Abstract: PURPOSE:To maintain a stable characteristic by installing a disk-like piston capable of pressure contact with a front cover lying between a turbine and this front cover and a viscous damper mechanism connecting the piston and the turbine through a working fluid. CONSTITUTION:When a front cover 3 is rotated, this rotation is transmitted to a turbine 5 via working fluid. When torque variation is transmitted at the time of lockup operation and a piston 12 and a case 14 are twisted to some extent, a branch chamber 14c is compressed and another branch chamber 14c is extended wide, whereby operating oil in the branch chamber 14b passes through a passage 19, flowing into the branch chamber 14c, and viscous damping force is produced in this passage 19, thereby absorbing torque variation. The working fluid in the branch chamber 14b passes through an engaged plate 17b from an oil passage 14d, flowing into a working fluid chamber of a torque converter 1, so the viscous damping force is also produced in this oil passage 14d. In succession, the working fluid flows into the branch chamber 14c via a notch 17b and the oil passage 14d. Since a viscous damper mechanism 13 holds the working fluid of the operating oil chamber jointly, it is able to cool the working fluid in a cooling part, thus the deterioration is checkable, and a viscous damping function is maintainable for a long period of time.

Title: Electrophotographic photoreceptor
Inventor: MISHIMA NAOSHI
IPC: G03G5/147
Filed: 1993-02-03
Abstract: PURPOSE:To improve the lubricity of a surface layer and to improve the cleanability and wear resistance by adding a diamond fine particle to the surfae layer. CONSTITUTION:An org. photoconductive layer is provided on a substrate directly or through an intermediate layer, and further an org. protective layer is provided, if necessary, to constitute an electrophotographic photoreceptor. A diamond fine particle is dispersedly incorporated into the surface layer part of the outermost surface. When the conductive diamond fine particle is added into a protective layer, the particle acts as a lubricant and an electric resistance regulating agent. Since even a trace amt. of the diamond particle improves lubricity, the particle can be used in the charge transfer layer of a laminated photoreceptor without any protective layer, the lubricity is increased as the average diameter of the particles decreases. Besides, the fine particle is obtained by exploding trinitrotoluene in an inert gas atmosphere.
