  • Printing apparatus and method for printing the inner surface of a cylindrical object
    Patent number: 5829350
    Abstract: The printing apparatus has a holding cylinder in which communication holes for communicating an external portion and an internal portion are made and a transfer pad which covers the outer surface of the holding cylinder at ordinary times in a detachable manner, expands upon pressure being applied via the above communication holes when the interior of the holding cylinder is pressurized, and contracts and returns to its original state when the pressure is released. Ink is adhered to the outer surface of the expandable/contractable transfer pad. The transfer pad is inserted in the contracted state into a cylindrical hole of an object to be printed. Pressure is applied from the inside of the transfer pad to cause it to expand and cause the outer surface of the transfer pad to press against the inner surface of the cylindrical hole and thereby transfer the ink adhered to the outer surface of the pad to the inner surface of the cylindrical hole.

  • Structure of a flat-type brushless DC motor
    Patent number: 4851731
    Abstract: A flat type DC motor applicable for disc drive of an electronic still camera in which vibrations of the rotor axle are prevented without increasing manufacturing costs by providing the magnetic field between the stator and rotor to by asymmetrical so that the magnetic attracting force of the rotor to the stator is also asymmetrical. The asymmetrical attracting force causes the axle of the rotor to be urged in the same radial direction relative to the axle bearing in the stator, thus, movements of the axle in radial directions in the clearance between the axle and bearing of the stator are eliminated and the rotor rotates without vibrating.
