摘要： PROBLEM TO BE SOLVED: To provide a stator for a dynamo-electric machine and a manufacturing method thereof, a jointing conductor and a manufacturing method thereof, capable of decreasing heat gain during a jointing process and ensuring high insulation performance by restraining damage to an insulating coating for reduction in the sectional area of the end of the conductor by plastic deformation to the end of the conductor, and realizing productivity improvement and cost reduction by preventing generation of short-circuit between jointed sections in structure and omitting a short-circuit repairing process by manual work which was required conventionally. SOLUTION: In a jointing conductor 1, the cross-sectional area of the conductor of an end 11 ranging from a tip to a prescribed boundary in the longitudinal direction is formed to be smaller than that of a main part 10. The main part 10 and part of the end 11 in the vicinity of the main part 10 are evenly covered with the insulating coating 2. Two jointing conductors 1 are jointed with the ends 11 aligned to each other.

摘要： PURPOSE:To improve the accuracy of assembly by generating oil seal performance for separating a low pressure chamber from a high pressure chamber via the application of light shrinkage coupling between a frame and a center shell using a shrinkage coupling tolerance approximately equal to or less than a half of the conventional tolerance, and applying spot weld for fixing the frame to the center shell. CONSTITUTION:As a crankshaft 6 is driven and rotated with an electric motor made of a rotor 8 and a stator 9, an oscillation scroll 2 oscillates to form a compression chamber with a fixed scroll 1. As a result, refrigerant gas drawn into a low pressure chamber 40 is compressed and delivered to a high pressure chamber 41. A sealing vessel is internally divided into the low pressure chamber 40 and the high pressure chamber 41 via the boundary of the shrinkage coupled section of a frame 7c and a center shell 23a. In this case, the shrinkage coupling tolerance of the frame 7c and the center shell 23a is approximately equal to or less than a half of the conventional case for providing light coupling state, thereby generating oil seal performance for separating the chambers 40 and 41 from each other. On the other hand, spot weld 51 is applied for fixing the frame 7c to the center shell 23a.

摘要： PROBLEM TO BE SOLVED: To improve the strength of a weld zone by flitting end faces of a pair of cylindrical members to each other, and forming a second weld zone extending to an outer circumferential surface of the cylindrical members across a fully fillet welded part between the outer circumferential surfaces. SOLUTION: A pair of cylindrical members 10, 11 are press flitted to each other with a margin at an end part, and the MAG welding is achieved so that the whole circumference between an end face of the cylindrical member 10 and an outer circumferential surface of the cylindrical member 11 is deposited by a fillet welded zone 12, and a second welded zone 13 is extended between the outer circumferential surfaces of the cylindrical members 10, 11 across the fillet welded zone 12. Because the second welded zone 13 is contracted and deformed, and the diameter of a fitted part of the cylindrical member 10 is reduced, the fitted part of the cylindrical member 11 is tightened, generation of the bending moment produced between the flitted parts due to the internal pressure is suppressed, and the strength is improved. The second welded zone 13 is arranged on the symmetrical position on the circumference. The strength of the welded zone is thus improved.

摘要： PURPOSE:To eliminate the need for a complicated correction polishing and to easily perform the highly accurate processing of the material difficult to be cut, by forming a layer having an equal polishing efficiency and a free-cutting property on the prework face of the material difficult to be cut and removing the layer by an equal polishing, after its working in a highly accurate face by cutting. CONSTITUTION:On the prework face of the material 1 difficult to be cut the layer 3 of a easily cut material having the polishing efficiency equal thereto is formed. The layer 3 of the easily cut material is then removed just as maintaining the shape thereof by the equal polishing with a diamond abrasive grains 5, after working this layer 3 by cutting with a diamond bite 4 in a highly accurate shape. Consequently, a highly accurate shape can be obtained without the need for a correction polishing.
