Abstract: A rotor for a vehicular alternating current generator has a relief space portion formed between axial holes of a pair of pole cores and a shaft for receiving therein a plastically deformed portion produced when the shaft is press-fitted in the axial holes of the pole cores. The relief space portion is located adjacent to a pair of closely contacting inner end faces of the pole cores so that the plastically deformed portion is let to move into a radially outward direction rather than further continuing movement in an axial direction within the relief space portion. The plastically deformed portion is thus prevented from entering between the inner end faces of the pole cores.

Abstract: A method of manufacturing a winding includes steps of twisting U-shaped conductor segments, inserting straight portions of the twisted conductor segments in slots of a stator core, bending ends of the straight portions in a circumferential direction of the stator core and joining the ends. The method further includes a step of pressing turn portions of the U-shaped conductor segments by a turn portion twisting apparatus such that widths of the turn portions reduce in radial directions. The pressing step is performed simultaneously with the twisting step. Alternatively, the pressing step is performed after the twisting step.

Abstract: A car shock absorber is positioned on a pit floor car between a car guide rail and the pit floor and/or between the car or counterweight and the pit floor. The car shock absorber has a shock absorbing body made of a deformable material in which a recess is formed. A pressing body is continuously engaged in the recess. When a shock load is input to a top part of the pressing body, the load is distributed in a direction perpendicular to inclined pressure and pressure-receiving surfaces, which are the contact surfaces between the pressing body and the shock absorbing body, thereby reducing the shock stress produced in the pit floor.

Abstract: Is disclosed an inclination sensor for detecting a tilted state of a case by detecting by a magnetic sensor a magnetized portion of a pendulum type movement mounted rotatably on a shaft in accordance with inclination of the case, wherein the shaft fitted with a clearance in a rotation shaft hole of the movement is further provided at both ends with loosely fitted thereon spacers and mounted in the case. This realizes non-restricted state of both the movement and the shaft. Thus, the movement obtains an improved response characteristic and an increased stability since no oscillation of a running vehicle is transmitted through the shaft to the movement.

Abstract: A method of manufacturing a rotary electric machine stator includes inserting straight portions of conductor segments into a plurality of slots of a stator core. The conductor segments are then bent so that connection ends of the conductor segments that are disposed adjacent to each other in a radial direction can incline in opposite circumferential directions to cross one another. Pairs of the connection ends crossing each other are then welded.
