摘要： A turntable-integrated spindle motor according to the present invention is constituted by a stator and a rotor. The rotor is constituted by a shaft 4 supported in a bearing in a cantilever support manner, a metallic rotor case 1 fixed to the shaft 4 by a boss 3, and a magnet 10 fixed to an inner circumferential surface of the rotor case 1. A plurality of projections 2 are formed integrally with the metallic rotor case so as to project from the side surface of the metallic rotor case, the projections being arranged along one circumferential line. The projections 2 perform a coming-off-prevention function by engaging with an engaging portion of a chassis 15. The rotor case 1 also functions as a turntable. In the present invention, the motor and the turntable are combined integrally with each other to obtain improved characteristics as well as to reduce the overall height. Also, projections for preventing coming off are formed integrally with the metallic rotor case to ensure high strength of the projections.

摘要： A tool driving section of a friction stir spot welding device is configured to cause each of a pin member and a shoulder member to advance and retract, and is controlled by a tool driving control section. A press-fit reference point setting section sets a position where the pin member or the shoulder member contacts an object to be welded as a press-fit reference point, and the tool driving control section controls the position of the pin member with respect to the shoulder member on the basis of the press-fit reference point, thereby controlling the press-fit depth of a rotating tool press-fitted from the surface of the object to be welded. This achieves the excellent welding quality at suitable precision according to welding conditions especially in a double-acting friction stir spot welding method.

摘要： A dissimilar material joint is formed by arranging a plurality of joint segments consecutively in a longitudinal direction. Each joint segment is formed by joining and integrating together a first member, an intermediate member, and a second member by explosive welding. A groove is formed in a joint end face of each joint segment, the joint end face being joined to another one of the segments, the groove spacing apart an end face of the first member and an end face of the second member from each other in a stacking direction. In the dissimilar material joint, the end faces of the respective first members of the joint segments that are adjacent to each other are joined together by welding, and the end faces of the respective second members of the joint segments that are adjacent to each other are joined together by welding.
