  • Patent number: 11110664
    Abstract: According to a method of the present invention for treating a terminal portion of an interior part for a vehicle, the terminal portion is stably maintained in a folded state by being welded firmly and deformation is constrained. In a heating step, in a state where distal end edges of heat shield panels 30A and 30B are abutted against a boundary between a terminal portion 4 and an adjacent portion 5 of a peripheral edge portion 3 of an opening of a roof trim 1 for a sunroof, hot-air is provided toward a back surface of the terminal portion 4 from hot-air nozzles 40A and 40B, thereby softening the terminal portion 4 and melting the back surface of the terminal portion 4. In a folding-back step, the terminal portion 4 is folded back by pressing members 50A and 50B at the distal end edges of the heat shield panels 30A and 30B and then pressed against the adjacent portion 5, thereby welding the back surface of the terminal portion 4 to a back surface of the adjacent portion 5.

  • Patent number: 10879751
    Abstract: A rotating electric machine has a drive control part and a motor having a stator and a rotor. The drive control part has an external disturbance voltage instruction generation part, a switching signal generation part, first and second drive circuits, a current acquisition part detecting an external disturbance current flowing in three phase winding in each of a first coil and a second coil of the stator, and a phase angle estimation part detecting a phase angle of the rotor of the motor based on the detected external disturbance current. The drive control part adjusts turn-on/turn-off timings of switching signals so as to reduce a timing difference between corresponding line external disturbance voltages in the three phase windings more than the time difference without performing the timing adjustment while maintaining a duty ratio of these line external disturbance voltages to that when the timing adjustment is not performed.
