Abstract: In this driving force transmission apparatus, with a simple constitution employing a one-way clutch 20 instead of an electromagnetic clutch, the driving force derived from the motor 33 can be transmitted to the rotating shaft 1 during engine stops, and the driving force of the engine can be transmitted to the rotating shaft 1 during engine operations. Also, the pulley 3 is held against the connecting portion 11 and the fixed-side member 26 by means of first and second two ball bearings 21, 30 disposed axially adjacent to first and second inner cylinder portions 6, 7, respectively, between which the opening portion 5 of the pulley 2 is interposed. This simple driving force transmission apparatus can switch between transmission and non-transmission of driving force from pulley to rotating shaft, and transmits the driving force of a motor directly to the rotating shaft in the non-transmission state.

Abstract: An air conditioner for air conditioning the interior of a compartment having a compressor, an electric motor, a detection device, a rotation speed sensor, and a controller is provided. The compressor compresses refrigerant gas and changes the displacement. The electric motor drives the compressor, and is capable of rotating at a constant reference rotation speed. The detection device detects information related to the thermal load on the air conditioner. The rotation speed sensor detects the rotation speed of the motor. The controller computes a target torque of the compressor at the reference rotation speed of the motor based on the thermal load information detected by the detection device, and computes an input current value to be supplied to the motor. The input current value corresponds to the target torque.

Abstract: A piston-type compressor has gaskets located between a cylinder blocks and front and rear housings mated to the cylinder blocks. The front and rear housings are made of magnesium alloy, and cylinder blocks are made of aluminum. The gaskets are constituted of resilient material and contain white carbon or a mixture of white carbon and black carbon to provide a superior electrical non-conductivity. The gaskets electrically isolate the housings and cylinder blocks so as to prevent a galvanic corrosion at surfaces where the two different metals of the compressor components are jointed.
