Title: Printed circuit board and connecting pin
Inventor: ASARI SHIGEATSU
IPC: H05K1/11
Filed: 1990-04-18
Abstract: PURPOSE:To increase the mounting density on a printed circuit board and facilitate manufacture by suching molten solder along the inner surface of a through hole and a connecting pin by means of capillary phenomenon, and connecting the wiring pattern on the board electrically through the molten solder. CONSTITUTION:When a printed circuit board 11 with a connection pin 15 inserted is dipped in a solder bath, the molten solder 16 is sucked up through the action of surface tension into the hollow 15c of the connection pin 15 from the undersurface of the circuit board 11 and leaks out onto the wiring pattern 12 from the folding part 15b of the connection pin 15. The leak solder 16 flows around along the periphery of the pin 15 and permeates the wiring pattern 12. Thereby the patterns 12, 13 are put in electrical connection through the molten solder 16 and connection pin 15. Thereby electrical connection can be made on both sides of a printed circuit board not having undergone a through hole processing, which permits mass-production of circuit boards at a low cost, and also the mounting density can be increased.

IPC: F15B11/00
Filed: 1988-04-27
Abstract: PURPOSE:To improve responsiveness and to prevent the generation of cavitation by flowing a part of pump discharge oil to a bypass selector valve through a flow control valve. CONSTITUTION:A part of fluid from a pump 10 is discharged into a tank 23 through a flow control valve 14, a bypass selector valve 16, and a pressure generating apparatus 17. When a selector valve 12 is located in the neutral position, the aperture surface area of the bypass selector valve 16 becomes large, a pilot signal pressure rises, and the discharge rate of the pump 10 becomes minimum. Also, a surge pressure is absorbed in a bypass passage and responsiveness is improved. Further, in the case of heavy loading, a flow amount of the bypass is decreased and a discharge amount of the pump is increased so as to prevent cavitation from being caused.

IPC: F16D13/71
Filed: 1987-04-27
Abstract: PURPOSE:To enable an initial set load to be maintained, by heightening automatically the supporting points in correspondence to the amount of abrasion of a facing. CONSTITUTION:When some amount of abrasion w is caused on the facing 6, such an inclination as the outer circumferential end part inclines toward the pressure plate 7 side is caused on a diaphragm spring 8, so that a clearance is produced between the supporting point 23 of a first fulcrum ring 14 and the diaphragm spring 8. And, when the clutch is brought back to the connected condition, the clearance corresponding to the amount of abrasion w of the facing 6 is removed. In other words, the fulcrum rings 14, 15 are heightened as much as the height corresponding to the clearance. Thus, since the supporting points 23, 24 are automatically heightened in correspondence to the amount of abrasion of the facing 6, the set load during use can be always kept at a constant value.
