摘要： PROBLEM TO BE SOLVED: To miniaturize a member to be machined member(s) and a resin material, in a laser machining structure in which welding is performed by irradiating the surface of the members with a laser beam, and to prevent the resin material from eroding through a reflected laser light beam generated from the surface of the members when welding, wherein the resin material for covering the member is arranged near the surface of the members. SOLUTION: Welding is performed by irradiating the surface of two members 1, 2 with a laser beam 4. In the laser beam machining structure of the two members, the resin material covering the members 1, 2 is arranged at a position that receives the reflected laser light beam when the machining zone 6 surface is irradiated with the laser beam 4. For the resin material 5 so arranged at the position receiving the reflected laser light beam 3, there are used resin materials 5a, 5b that transmit the reflected laser light beam. As a result, the resin material 5 is prevented from eroding by absorbing the reflected laser light beam 3 from the machining zone 6 surface when the laser beam 4 is emitted thereto for the two members 1, 2.

摘要： PROBLEM TO BE SOLVED: To reduce man-hours for fabrication and realize uniform organization using a phosphor-copper brazing material as a bonding material and providing an annular groove to place the phosphor copper brazing material at the end part of the end ring. SOLUTION: A plurality of rotor conductors 2 are inserted and arranged in the same pitch into a laminated rotor core 1 and an end ring 3 having the slot grooves in the same pitch as the rotor core 1 is inserted and arranged to the end part of the rotor conductor 2 projected from the end part. The end part of the rotor conductor and the end ring 3 are joined by the brazing with the phosphor-copper brazing material, but the end ring 3 is provided with an end face annular groove to place the ring type phosphor-copper brazing material. When it is heated by a high frequency power supply, it is fused for the brazing. All rotor conductors 2 make a continuity. Thereby, a cage of the cage type rotor is formed and a shaft 4 is inserted and fixed at the center of rotation to form the rotor. Thereby, all slots of the single side end ring are formed simultaneously with fluxless method, realizing reduction in man-hours and uniform organization of the junction area.

摘要： PROBLEM TO BE SOLVED: To obtain a highly reliable coupling structure, having a stable coupling force between a bundling terminal and lead-out coils of a lead-out coil set, by joining the lead-out coils with the bundling terminal, in such a state that partial periphery of each lead-out coil is brought into contact with the terminal. SOLUTION: Neutral point lead-out coils 2N are alternately arranged in two stases in a staggered state, with three rows being arranged in the lower stage and four rows being arranged, including a neutral point output terminal N in the upper stage, so that the coils 2N in the upper stage cannot overlap the coils 2N in the lower stage. The arranged coils 2N are bundled by means of a bundling terminal 12, made of a copper-based material in a state where the coils 2N are electrically and mechanically coupled with the terminal 12 through a brazing material and, in addition, the coils 2N are press-contacted with each other. The coils 2N are composed of enameled conductors, namely, AIW wires and a copper alloy terminal which leads to good results, when the AIW wires jointing to the terminal by electric heating is used as the terminal 12. Therefore, a highly reliable coupling structure, having a stable coupling force, can be obtained between the bundling terminal an the lead-out coils.

摘要： PURPOSE:To make it possible to detect the state of an air fuel ratio in a broad range and to improve heat resistance and durability, by forming a thin film layer that is formed on a surface of a plasma flame coating layer by a PVD (Physical Vapor Deposition) method so that the thin film layer is finer than the plasma flame coating layer. CONSTITUTION:A detector is formed by the following way: porous electrodes 2 and 3 having catalytic property are arranged on the upper and lower surfaces of a solid state electrolyte element 1 having oxygen-ion conducting property; and a gas-diffusion resistance layer 4 for determining the rate of passing gas is applied on the surface of the electrode 2 of said electrodes 2 and 3 which is arranged on the side of a gas atmosphere to be measured. In the resistance layer 4, at least one layer is a plasma flame coating layer 4a using an electricity insulating metal oxide having an adequate grain size and the other layer is a thin film layer 4b which is formed on the plasma flame coating layer 4a by a PVD method. The thin film layer 4b is a layer that is finer than the flame coating layer 4a. In this way, thermal stress due to the difference between the thermal expansion coefficients of the resistance layer 4 and the element 1 is decreased, and the occurrence of cracks can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a connecting structure and a connecting method of a terminal wherein another terminal can be joined surely to the terminal extending in the longitudinal direction while pressurized.
SOLUTION: A convex part inclined in a short side direction across both ends of the short side of the terminal extending in the longitudinal direction is press molded, and another terminal is connected to this convex part by electric resistance welding or the like while pressurizing. At this time, since the convex part is inclined to the short side direction of the terminal, the convex part is not deformed to be smashed, and a contact area between the terminals can be secured sufficiently.
