  • Publication number: 20240132147
    Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

  • Patent number: 8118522
    Abstract: A working apparatus, provided with a base stage, work hold and rotation device for holding and rotating a work, working device movable toward and away from the work via slider mechanism and having a working tool, press structure for pressing the working tool toward the work via the working device, and trace device pressed toward the work together with the working tool by the press structure and in contact with the work and moving the working device as a whole in forward and rearward directions according to outer shape of the work. By pressing of the pressing structure, the working tool deburrs and chamfers under control of working volume by the trace device. The work hold and rotation device has work rotation axis angle adjustment mechanism, for adjusting angle of rotation axis of the work by holding the work. The working apparatus can precisely deburr and chamfer complicated shape of work such as worm gear.

  • Patent number: 5603880
    Abstract: It is an object of the present invention to realize a method and an apparatus for efficiently mass-producing tablets of high mechanical strength, accuracy and quality which are so excellent in solubility and collapsibility that they can be easily taken by persons of advanced ages and infants. By using a turn table and endless belt means to which a number of dies are connected, a part of which turn table contacts with the endless belt means, the turn table and the endless belt means being adapted to relatively move with respect to each other, receptacles are formed by pressing plastic polymer film in mold cavities of the dies. Moist powder supplied from a hopper into filling holes of the turn table is pressurizingly filled in the receptacles by means of a filling and pressurizing device in the region where the turn table is laid above the endless belt means.
