Title: Earthquake-force reducing device
Inventor: KONDO HIROBUMI
IPC: F16F3/10
Filed: 1985-12-16
Abstract: PURPOSE:To reduce the earthquake force acting on a structure, by placing friction plates one over another and in parallel with a laminated rubber so that the friction plates adjoining to each other act as friction surfaces. CONSTITUTION:A laminated rubber 1, in which rubber plates 2 and metal plates 3 are adhered to each other in an alternate manner, has the soft property in the horizontal direction and the rigid property in the vertical direction. A lower flange 4 is directly fixed to the bottom end of this laminated rubber 1, while an upper flange 6 is fixed to the top end of the rubber 1. The laminated rubber 1 is provided with a through-hole, which is normal to the laminate surface. Inside the laminated rubber 1 are placed friction plates 7 one over another in such a manner that the friction plates 7 are parallel with the laminated rubber 1 and that the height of both becomes almost equal to each other. With this contrivance, when the earthquake reducing device is deformed by the earthquake force, the rubber plates 2 cause the shear deformation in the horizontal direction. At the same time, the friction plates 7 also move in the horizontal direction in correspondence to the deformation of the laminated rubber 1. Thus, a slip takes place at the contact surface between respective friction plates, thereby reducing the earthquake force.

Title: Compressor
Inventor: TAKEI YUJI
IPC: F04C21/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To attain miniaturization, weight reduction and high performance with high compression efficiency and little noise and vibration by oscillating a disc-like oscillating piston in a fluid sealed chamber formed of a cylinder liner, a pair of cylinder heads and a vane. SOLUTION: An oscillating piston 5 is laterally oscillated. In order to rotate crank pins 4, 4, while conical faces 600, 610 of cylinder heads and a disc face 500 of the oscillating piston 5 are always in line contact in one place on a circumference, a line contact part gradually moves along the conical faces of the cylinder heads like a waving phenomenon to perform intake-compression action. The oscillating piston 5 is only oscillated without being rotated, but since the line contact part appears as if it were moving, the oscillating piston 5 appears as if it were rolling. Suction-discharge action is performed in the same way on the opposite side of the oscillating piston 5. Since intake- compression action is performed without interruption, pulsation is reduced.
