Abstract: PROBLEM TO BE SOLVED: To provide a motor-driven type door releasing apparatus in which a consumption power and noise are restricted and its low cost is attained. SOLUTION: A predetermined voltage is applied only for a predetermined time after starting a motor 57 to open a door through an output shaft 56. After this applying operation, the voltage is lowered to a lower value than the predetermined voltage and when the output shaft 56 is retracted after stopping of operation of the motor 57, the value is further lowered to a lower value, so that the maximum requisite output is generated only at the time of the largest load in operation with the result that a surplus consumption power can be reduced and noise at the time of operation of the motor 57 can be restricted.

Abstract: PURPOSE:To simplify the structure of the title device and permit the coping with the control of a chamber by a method wherein an inlet part of a housing and a plurality of outlet ports, which are communicated with the inlet part of a housing, are opened and closed by a rotor driven by single driving source. CONSTITUTION:When a signal enters from a control circuit, a motor 16 is driven and the rotation of the motor 16 is transmitted from the final output stage 18a to a rotor 19 through a reduction gears group 18 whereby the rotor 19 is turned in the annular recess 12 of a housing 10. In this case, the original point of the rotating position of the rotor 10 is detected by a method wherein a lead switch 12, embedded into the housing 10, is put ON when the damper unit 19b of the rotor 10 has closed the inlet unit 14 of the housing 10 whereby an external control circuit is inputted. An outlet port 15a is communicated with a first chamber and another outlet port 15b is communicated with a second chamber. When only the temperature of the second chamber is increased and the temperature of the first chamber is low, for example, the motor 16 is electrified for a given period of time so that the rotor 19 is turned by 90 deg. from this condition by the external control circuit whereby the outlet port 15a is closed. According to this method, cold air may be ventilated into the second chamber through a discharging port whereby cooling may be effected.

Abstract: PURPOSE:To obtain a high reliability damper opening/closing device by mounting a shape storage alloy coiled spring on an opening/closing plate and a substrate through a holder including a hold part for holding a connection part between a heater of the coiled spring and a lead wire. CONSTITUTION:A linear heater 15 having an insulating coating is wrapped around a shape storage alloy coiled spring 14. A coil storage end is inserted through four or more holes 16a formed in a flaty holder 16 and is rotatably engaged with the opening/closing plate 12 and a substrate 10 via a hook part 16b. When temperature in the cooling chamber is higher than a set value, the heater 15 is supplied with power, whereby the shape storage alloy coiled spring 14 is contracted to rotate the opening/closing plate 12 in an opening direction for permitting cool air to flow into the refrigerator from the open part 11. Reversely, once it is lower than the set value, the power supply to the heater 15 is stopped, whereby the temperature of the shape storage alloy coiled spring 14 is lowered to reduce an output therefrom, so that the opening/closing plate 12 is rotated in an closing direction by the spring 13 to close the opening part 11 of the substrate 10 for interrupting the flow of the cold air onto the refrigera tor. Thus, reliability is improved.

Abstract: PURPOSE:To reduce an energy loss and accurately maintain a temperature in a casing by embedding heating wires in the circumference of housing openings, which are provided between a cold air inlet part and its outlet part and which are opened and closed by the vanes of a rotor, and disposing a detecting switch for supplying power to heaters when the rotor closes the openings. CONSTITUTION:A drive signal is sent to a motor 34 to allow a rotor 38 to rotate via a reduction gear 35, and the vaned 38b, 38c of the rotor 38 rotate in the direction in which two openings 25a, 25b provided in the annular recess 20a of a housing 20 are closed. In this case, pressure-sensitive, electrically-conductive rubber members 29 provided at the openings 25a, 25b are brought into contact with metal pieces 40 provided at the vanes 38b, 38c of the rotor 38, and when the rubber members are pressed under substantial pressure, the pressure-sensitive, electrically-conductive rubber members 29 conduct to cause the electric current of a signal to flow between two electrodes 28, thereby supplying power to heaters 27 and heating the outer frames 26 of the openings 25a, 25b. By this method wherein power is supplied to heating wires only when the rotor, which is most susceptible to freezing, continues the state of closing the openings, an energy loss can be made less than that in the case of the constant supply of power to the heaters.
