  • Cooling device
    Patent number: 11421676
    Abstract: Provided is a cooling device capable of surely stopping the operation of a compressor when stopping the operation of the compressor is required. A cooling device comprises: a motor for driving a compressor that constitutes a refrigerant circuit for cooling a cooling room (R); and a first relay and a second relay that are arranged in series on an electric circuit for supplying electric power to the motor.
    Type: Grant

  • Optical disc drive and optical disc discriminating method
    Patent number: 6956801
    Abstract: In an optical disc drive capable of recording and playing back different kinds of optical discs, an actuator driving means brings an objective lens close to the optical disc, focus error signals are generated in front of and behind a position where leaser beam comes into focus on a signal surface of the optical disc, optical disc discriminating means discriminates a thickness of the optical disc from a difference in waveform of the focus error signal which is generated by focus deviation between leaser beam which passes through an outer periphery of the objective lens and leaser beam which passes through an inner periphery of the objective lens, and discriminates a kind of the optical disc from the thickness of the optical disc.
