    摘要: A circuit unit is used in an electronic instrument having a key-pad arrangement, such as a portable telephone, and comprises a printed circuit board, a flexible switch circuit sheet attached to the printed circuit board and having a plurality of switch pads arranged thereon, and at least one circuit pattern formed in the flexible switch circuit sheet so as to construct a switch circuit together with the switch pads. The circuit pattern includes a plurality of line sections extended between the switch pads, and a plurality of terminals provided along a peripheral edge of the flexible switch circuit sheet for establishing an electrical connection between the printed circuit board and the flexible switch circuit sheet.

    摘要: A swash-plate type compressor comprises a plurality of cylinder chambers parallel to each other, a shaft, a swash plate connected to the shaft for rotation therewith and for wobbling motion due to the rotation, and a plurality of pistons subject to wobbling motion of the swash plate for reciprocation within the respective cylinder chambers. The shaft and the swash plate are connected to each other through a slot formed in one of them and a pin provided on the other, so the swash plate can wobble. A position of a center of rotation of the swash plate is supported by a spool device movable in coaxial relation to the shaft. Displacement of the spool device causes the position of the center of rotation of the swash plate and an inclination thereof to be varied to vary a reciprocative stroke of each piston, thereby controlling discharge capacity of the compressor. The engaging slot has a section thereof between positions corresponding respectively to a maximum discharge capacity and an intermediate discharge capacity of the compressor, which section is formed into a nonlinear configuration in such a manner that an angle between a normal line of the slot and an axis of the shaft decreases at a position corresponding to a large discharge capacity of the compressor, thereby restraining an increase in inclined moment acting upon the swash plate due to a dead volume occurring in the working chamber on one side of the piston at a large capacity of the compressor.

    摘要: A rotary compressor formed with an unloading port maintaining a working space in communication with a suction chamber and opened and closed by a valve, to vary the capacity of the compressor. The internal pressure of the working space is sensed in a compression stroke or this pressure and the pressure of a fluid drawn by suction are both sensed, so as to open and close the valve based on the sensed internal pressure of the working space or the pressure differential between the internal pressure of the working space and the pressure of the fluid drawn by suction, to give suitable hysteresis to the operation characteristics of the on-off valve to stabilize the operation of the on-off valve.

    摘要: A heating apparatus for a vehicle includes a pump for circulating cooling water in a cooling water circuit, a heating heat exchanger for heating air blown into a passenger compartment of the vehicle using cooling water as a heating source, and a throttle valve disposed at a discharge side of the pump. In the heating apparatus, when the temperature of cooling water is low and heating capacity for heating the passenger compartment is insufficient, an opening degree of the throttle valve is reduced by a control unit. Therefore, heat is generated from the throttle valve and the pump so that the temperature of cooling water is increased. Thus, heating capacity of the heating apparatus can be improved without using a manual operation.
