  • Patent number: 10658904
    Abstract: A rotating electrical machine includes: a rotor; a stator; a high voltage bushing; power lines connecting the stator coil to the bushing; a support insulator that supports the power lines; a rotating electrical machine outer casing that contains at least the rotor, the stator and a connection portion between the stator coil and the power lines, and is filled with hydrogen gas; and a terminal box which communicates with the outer casing and is attached to a lower portion of the outer casing, the insulator installed in the terminal box, and terminal box containing at least the power lines supported by the insulator and a part of the bushing connected to the supported power lines. The insulator is installed vertically on a bottom face of the terminal box, and the vertically installed insulator and a portion of the bushing in the terminal box are disposed in parallel with each other.

  • Patent number: 6583773
    Abstract: A display drive mechanism for vehicle slidingly moves a display assembly between a stored position and a projected position by the drive force of a motor. The display drive mechanism comprises a rotating body which is rotationally driven by the motor. A projecting portion for example projects from the rotating body at a position eccentric to its axis of rotation. A long slot in the display assembly is engaged with the projecting portion. The display assembly is driven to and fro in both directions between the stored position and the projected position, as the rotating body rotates.
