Title: Scroll compressor
Inventor: LIFSON ALEXANDER
IPC: F04C18/02
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To reduce a component of separation force applied between scroll laps by connecting pressure between one of a low pressure chamber and a top end of at least one of the scroll lap, on a position of one scroll lap side in order to reduce all separation force between scroll laps. SOLUTION: Since shallow recesses 42 formed on the top end of a fixed scroll lap extend an inner wall 44 adjacent to a high pressure side of a scroll lap 41 and a low pressure rim 46 of the scroll lap 41, a low pressure fluid from the low pressure rim 46 is moved to the inside of the recess 42 and the inner wall 44. When a scroll compressor is moved by either one of scroll lap 41 of a fixed or turning scroll, high pressure is extended to a high pressure rim 45, and low pressure is extended inward to the inner wall 44 through the scroll lap 41. Since inclining from high pressure to low pressure is generated between the inner wall 44 and the high pressure rim 45, a range on which high pressure is acted is reduced, and thereby, it is possible to reduce separation force.

IPC: H01S5/00
Filed: 1987-11-27
Abstract: PURPOSE:To obtain a planar type semiconductor laser having high yield, low cost and high reliability by specifying the width of a clad layer of the laser by an ion implantation, and further specifying a current path of narrower width than that of the clad layer. CONSTITUTION:A clad layer of a semiconductor laser is partly or all formed of a superlattice crystal, ions are implanted to the superlattice layer except a section which becomes an optical guide layer, and then heat treated to disorder the superlattice. Thus, the superlattice crystal position which is not disordered is operated as the optical guide layer. Then, the clad layer is ion implanted except the top of the optical guide layer to form it semi-insulating, thereby forming a current block layer. Thus, since a laser can be formed by a simple photolithography and an ion implantation, the steps can be simplified and the yield can be improved.
