Abstract: PURPOSE:To eliminate unevenness in defreezing operation and enable a defreezing to be carried out within a short period of time by a method wherein a refrigerator has a defreezing control device in which during a defreezing operation in which a defreezing chamber temperature sensing means detects a higher temperature than a set temperature, an efficiency of electrical energization for a far infrared ray heater and a heater is decreased to control an electrical energization and in turn during a non-defreezing time, the defreezing chamber is kept at the third temperature range between the refrigeration temperature and a freezing temperature. CONSTITUTION:During a normal defreezing operation, a direct radiation is carried out by a far infrared ray heater 34 from an upper surface and a side surface of a defreezed food 45, a transmitted heating from a heating heater 42 at a bottom surface is carried out to perform a thermal absorption. Concurrently, during a defreezing operation, a damper thermostat 20 is opened, a cooling blower 18 is continuously operated, a clod air is uniformly supplied to a defreezed food through a passage in an upper spacing so as to restrict an increasing in temperature at the surface of the food. In the event that a temperature in the defreezing chamber is increased higher than a predetermined temperature during a defreezing operation, a thermal radiation amount of the far infra-red ray heater and a transmittance amount of the heating heater are decreased to restrict a food surface temperature from being increased. In addition, upon completion of the defreezing operation, the food temperature is automatically kept at the third temperature range between a refrigeration temperature and a freezing temperature under a temperature adjusting operation of the damper thermostat and its cold state is kept.

Abstract: PURPOSE:To attain speed control for an optical head requiring no mechanical part by performing the speed control after detecting speed electrically from the both-terminal voltage of a voice coil and the current flowing ot the voice coil. CONSTITUTION:A speed detecting means consists of a voltage sense circuit 3 which detects the both-terminal voltage of a voice coil 2 of a voice coil motor, a current sense circuit 5 which detects the current flowing to the coil 2, and a computing element 6 which inputs the outputs of both circuits 3 and 5 and outputs a speed signal to control the speed of an optical head. A speed signal 7 is obtained by choosing properly the gains of the stages of the circuits 3 and 5 and the element 6 respectively. The signal 7 is compared with a reference speed signal 8 and fed back to a power amplifier 1 to control the speed of the coil 2. Thus it is possible to perform the speed control of the optical head without using any external speed detector which requires a mechanical part.
