Abstract: PURPOSE:To mitigate vibration and noise of a compressor in an air conditioner for an electric vehicle while it is at a stop. CONSTITUTION:This control device is provided with a car speed detecting switch 18 and a rotating speed limiting means 13a, controls a rotating speed control circuit 10 based on the output of the car speed detecting switch 18, and stopping an automobile when by setting the maximum rotating speed of a compressor 50 with an electric motor lower than that at running, noise and vibration of the compressor at stopping the automobile are reduced.

Abstract: PURPOSE:To prevent the generation of die flaws onto the surface of a rotor by supplying lubricant from outside constantly into the vane groove bottom part formed part of a billet during its extrusion process. CONSTITUTION:In the method of manufacturing a rotor by extrusion molding a billet made of an alluminum alloy, lubricant 8 is constantly supplied into the vane groove bottom part formed part of the billet 13 during its extrusion process by a die 2, from a hopper 9 through a lubricant supply part 3. Extrusion resistance can be thereby suppressed to a low degree during the whole extrusion process so as to prevent the generation of die flaws to the vane groove bottom part of the rotor.

Abstract: PURPOSE:To uniformly apply plating to the top surface and rear surface of the head section of a vane by arranging one or more of vane in plating liquid and forming a coated layer on the surface of the vane with plating liquid stirred such that hard particles are blowed up. CONSTITUTION:Hard particles 23 are contained in plating liquid 22 mainly comprising Ni-P at the specified content ratio. A plurality of vanes are arranged with the top surface 8c of the head section of each vane B being at upper position and the rear surface 8b facing upward in the plating liquid 22, In the next step, the plating liquid is stirred such that the hard particles 23 are blowed up to form the coated layer of plating covering the portion from the top surface 8c of the head section of each vane 8 to the rear surface 8b. In such manner plating can be applied uniformly on the vanes.
