Title: Variable displacement type swash plate compressor
Inventor: OKUDA KIYOMI
IPC: F04B27/14
Filed: 1992-06-18
Abstract: PURPOSE:To smooth a variation in discharge quantity by preventing a control piston in a variable displacement type swash plate compressor from being tilted and locked in a control cylinder. CONSTITUTION:A disklike control piston 70 is inserted into a control cylinder 18 of a housing slidably in the axial direction, and in the peripheral edge, there is provided a clearance in order to allow its free slide motion and an O-ring 72 is sealed therein. When a compressor is operated, a small diametral part 68b of a sleeve presses the control piston 70, but in such a case as filling up a refrigerant, if air in a system is exhausted by a vacuum pump in advance, the control piston 70 is shifted to the right by dint of decompression in a control pressure chamber 74, while since the small diametral part 68b of the sleeve will not follow it, it has separated, thus the control piston 70 is tilted and locked. Therefore, a control piston supporting part 80 and a guide cylinder 82 both are installed, guiding and supporting it in the axial direction.

Title: Power supply
Inventor: CHIISAGATA MASAAKI
IPC: H02M3/155
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown of transistors by connecting a variable resistor circuit to a control electrode, and suppressing rush current by varying a resistance value. SOLUTION: When power is applied to the DC/DC converter, input voltage VIN is applied between the emitter and collector of a first transistor Q1 because output voltage VO is a ground voltage. Since output voltage VO is a ground voltage, a third transistor Q3 is turned off, and a control circuit 3 turns on a second transistor Q2 because the output voltage VO is at low level. For the current flowing to the output side through the transistor Q1 in this state, the base current is small because of the high resistance of a first resistor R1, and the voltage of a capacitor C2 is gradually increased by the small current. When the output voltage VO becomes high to some extent, the third transistor Q3 is turned on. As a result, rush current can be suppressed at power application or at short-circuiting on the output side, and breakdown of the transistors can be prevented.
