Abstract: To fasten an auxiliary crank for prevention of autorotation of an orbiting scroll to a compressor-casing side bearing in a scroll compressor, a tool must access from a motor side to a compressor casing so as to fasten the auxiliary crank to the compressor-casing side bearing. Therefore, fastening between the auxiliary crank and the bearing cannot be made after a motor section and a compressor body are fastened together. This necessitates the steps of: separating the compressor body from the motor section; fastening the auxiliary crank to the compressor casing; and then fastening the compressor body and the motor section together. A compressor-motor integrated scroll compressor cannot be assembled in sequential steps, entailing increased assembly costs and lowered maintenability. A plurality of notches or holes is formed on a motor housing or the compressor casing.

Abstract: When a laser beam is irradiated onto a semiconductor film, a steep temperature gradient is produced between a substrate and the semiconductor film. For this reason, the semiconductor film contracts, so that a warp in the film occurs. Therefore, the quality of a resulting crystalline semiconductor film sometimes deteriorates. According to the present invention, it is characterized in that, after laser beam crystallization on the semiconductor film, heat treatment is carried out so as to reduce the warp in the film. Since the substrate contracts by the heat treatment, the warp in the semiconductor film is lessened, so that the physical properties of the semiconductor film can be improved.

Abstract: A microwave enhanced chemical vapor deposition method is provided for coating plastic articles with crystalline carbon films. First, a reactive gas including hydrogen gas and a carbon containing raw material gas is introduced into a reaction chamber. Next, a magnetic field is established in the reaction chamber. Microwaves are next introduced into the chamber to create a cyclotron resonance in order to form a plasma of carbon and hydrogen containing gas. The carbon containing plasma deposits a coating of a crystalline and amorphous carbon on a substrate placed within the reaction chamber, while the hydrogen plasma simultaneously etches away the amorphous carbon, thereby leaving only crystalline carbon. The method is particularly adapted for the deposition of crystalline carbon films on plastic materials, as the substrate is not required to be heated in order to receive a layer of crystalline carbon.
