Abstract: A defrost heater, in which the strength of an insertion force needed for inserting a second glass tube in a plug is specified to be smaller than that needed for inserting a first glass tube in a plug. Thereby, dispersion in the insertion force needed for attaching the plug with a double glass tube can be reduced, and the assembling efficiency is improved.

Abstract: PROBLEM TO BE SOLVED: To control opening/closing of two flaps without providing a position detection means, in a damper device for opening/closing the two flaps. SOLUTION: When a motor is rotated by a first predetermined amount in one direction, both of the first flap 105 and the second flap 106 are opened. When the motor is rotated by the first predetermined amount in the one direction and then rotated in the other direction by a second predetermined amount which is smaller than the first predetermined amount, the first flap 105 is closed and the second flap 106 is opened. When the motor is rotated by the first predetermined amount in the other direction, both of the first flap 105 and the second flap 106 are closed. When the motor is rotated by the first predetermined amount in the other direction and then rotated in the one direction by the second predetermined amount which is smaller than the first predetermined amount, the first flap 105 is opened and the second flap 106 is closed.

Abstract: PROBLEM TO BE SOLVED: To provide a defrosting heater which prevents inflammable refrigerant from catching fire even in the case that defrosting operation is carried out under an environment where leakage of the refrigerant occurs. SOLUTION: The defrosting heater is constituted of first glass tube 53, second glass tube 54 installed so as to cover the outer circumference of the tube 53, a heater wire 52 comprised of a metal resistive element which is installed inside the first glass tube 53, a stopper 58 blocking up openings of both ends of the first glass tube 53 and the second glass tube 54, and a lead wire 55 penetrating the stopper 58 and being connected to an end of the heater wire 52. A connection part of the heater wire 52 and a code 55 is provided with a positioning plate 57 which is held by the stopper 58 and which prevents the connection part from deviating. The size of clearances 58b formed by the stopper 58 and the positioning plate 57 is arranged in accordance with an amount of the trapped inflammable refrigerant and a surface temperature of the heater wire 52 during current-carrying to the heater wire 52. Therefore, since flame is not propagated, safety is kept at all times.

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: PROBLEM TO BE SOLVED: To provide an ice making pan, wherein even when small and light weight ice with a small volume, hard ice can be made, and the ice is easily separated, and an automated ice making apparatus or a freezing refrigerator with the pan. SOLUTION: Water is frozen in one direction from an upper section opening 10a of a recessed portion toward a lower portion 10c of the recessed portion, and when ice is expanded in the neighborhood of the recessed portion lower section 10c, extruding force against an inner wall of the lower section 10c of the recessed section 10 is applied in the direction where the ice is pushed out upward of an ice making pan 9. The upward force is not suppressed because the upper surface opening 10a of the recessed section 10 is spread, and hence the ice is separated from an inner wall of the recessed section 10 just-after ice is made without suppressing the force extruded upward.

Abstract: PROBLEM TO BE SOLVED: To simplify a water supply device and to reduce the generation of noise through suppression of displacement in a position between a drive part for the water supply device and a water supply pump, and to stabilize transmission of a rotation force. SOLUTION: The water supply device comprises a water supply pump 14 consisting of a rotary member 18 rotated in a tank 12 and exerting movement energy; and a drive part 15 installed at the tank 12 and making contact with the rotary member 18 and transmitting a rotation force. A conduction plate 36 for receiving a power is exposed to the drive part 15, and a conduction plate 36 for feeding a power source is exposed in a spot where the tank 12 is installed. When the tank 12 is installed by bringing the conduction plate 26 of the drive plate 15 and the conduction plate 36 into contact with each other in a state to be positioned opposite to each other, the drive part 145 and the tank 12 can be formed integrally with each other to simplify a device, and further a contact position between the drive part 15 and the water supply pump 12 is stabilized, resulting in stabilization of transmission of a rotation force. The generation of noise can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To purify water in a tank by operating a water feeding pump arranged in the tank. SOLUTION: In the tank 112 which stores water, the water feeding pump 113 is arranged. In this case, the water feeding pump 113 is constituted of a hollow cylindrical section 117, an impeller 119, a suction port 120, a discharge port 121, and a discharging pipe 115. The outer periphery of the hollow cylindrical section 117 is covered with a water-purifying filter 118. The impeller 119 is arranged in the hollow cylindrical section 117. The suction port 120 is provided on the side wall of the hollow cylindrical section 117. The discharge port 121 is provided on the hollow cylindrical section. One end of the discharging pipe 115 is connected to the discharge port 121, and the other end of the discharging pipe 115 is projected to the outside of the tank 112. Then, the impeller 119 is rotated in the opposite direction from the rotation by which water is discharged. Thus, the water in the tank 112 circulates in the water purifying filter 118 and the tank 112, and is purified.
