Filed: 1983-03-15
Abstract: PURPOSE:To make it possible to improve the sealing property of the titled device by setting a correct angular positional relationship between both seroll members and then determining correct angular positions of all mechanism, when assembling a compressor. CONSTITUTION:Since the pocket of a movable ring 51 and the pocket of a stationary ring 61 assume a state where the pockets of the rings pinch a ball 200 without any gap therebetween, the ball 200 moves in the driving direction responsive to the rotational movement of the movable ring 51, and further the stationary ring 61 is moved. Accordingly, all the mechanisms of a compressor 1 assume a state at the time of compression. For the last place, a front end plate 70 and a casing are fixed in the stationary hole by means of a bolt, and a locating rod 80 is pulled out. As a result, angular distortions of a crank mechanism, a movable scroll member 40, a stationary scroll member 30, a ball coupling mechanism and the casing, is eliminated, and the sealing property of the device is improved.

Abstract: PURPOSE:To make it possible to decrease the resistance of a diffusion layer by a method wherein the reaction of the diffusion layer with a metal is reduced, and metal silicide is formed to react a gas consisting of Si with a metal so as to form a thick, metal silicide film on a thin diffusion film. CONSTITUTION:A Pt-layer 7 is formed on a diffusion layer 2 that has been formed on a Si substrate 1. While a gas of SiH4 etc. is flown, the layer 7 undergoes heat-treatment to form a Pt silicide film 8. By adjusting the temperature of the substrate to 25 deg.C when the Pt film is evaporated, the reduction in the thickness of the diffusion layer Si is suppressed to 1/4 in comparison with the conventional method since the reacting speed of the Pt silicide by means of the reaction of Pt and SiH4 gas is about 3 times faster than that of the diffusion layer silicon. Moreover, by increasing the temperature of the substrate when the Pt film is evaporated, the reduction in the thickness of the diffusion layer can be further reduced since the reacting speed of Pt and Si for the diffusion layer will be further decreased.
