Abstract: PROBLEM TO BE SOLVED: To heat a drink in a container to a suitable temperature even if the temperature of a liquid serving as a heating source is lowered. SOLUTION: In this heater, a container having drink in it is moved in a hot water having a temperature higher than a target heating temperature of the drink in a container for a predetermined heating time to heat the drink in the container. A thermistor 15 is provided with a heating time setting means 20 for setting the heating time according to the measured temperature of hot water so that the lower the measured temperature of hot water is, the longer the heating time is, and a heating temperature select means 24 for selecting a target heating temperature of the packed drink. The heating time setting means 20 is adapted to set the heating time longer than that in the case of the ordinary target heating temperature when the target heating temperature selected by the heating temperature select means 24 is higher than the ordinary target heating temperature, and set the heating time shorter than that in the case of the ordinary target heating temperature when the target heating temperature selected by the heating temperature select means 24 is lower than the ordinary target heating temperature, whereby even if the temperature of hot water is lowered, heating can be accomplished to reach the selected target temperature.

Abstract: PROBLEM TO BE SOLVED: To prevent the failure in the starting of a refrigerating cycle device by detecting the load torque of a DC motor in the switching by the DC voltage of an inverter circuit, and executing the switching with a duty value corresponding to the load torque. SOLUTION: An operation mode switching means 20 connects a start sequence control means 13 to a composite means 21 in the starting, a torque-up means A 18 outputs the start sequence pattern A stored in a start sequence pattern storing means A 14 to a start sequence control means 13 to start the operation. Then a value of the DC voltage from a DC voltage detecting means 26 is detected and the torque-up means A 18 converts the optimum duty value on-load on the basis of a value of the DC voltage. That is, by using the torque-up means A 18, the load torque of the DC motor can be easily detected in the switching by the DC voltage of the inverter circuit, to execute the switching with the duty value corresponding to the load torque, whereby the failure in the starting of the refrigerating cycle device can be reduced.

Abstract: PROBLEM TO BE SOLVED: To minimize a circuit loss while a sufficient harmonic current suppression effect is maintained even if an input voltage fluctuates, by a method wherein the output voltage of an active filter is set at a voltage higher than the peak value of a power supply voltage by a certain level. SOLUTION: An AF drive circuit 35 controls ON/OFF of a semiconductor switching device 15 and consistently sets the output voltage of an active filter 12 at a voltage higher than the peak value of an input voltage set by a 1st voltage setting circuit by a certain voltage. With this constitution, even if the input voltage fluctuates, a circuit loss can be minimized and, further, a harmonic current can be sufficiently suppressed.

Abstract: PROBLEM TO BE SOLVED: To curb effervescence of liquid refrigerant at the outlet header of an evaporator and make a sudden liquid back less possible to occur by a method wherein for a preliminarily set time at the start a minimum value is set for the number of revolutions of the compressor and subsequently the operation is controlled at an optimal number of revolutions for the control of the storage temperature. SOLUTION: A freeze chamber temperature differential-calculating means 24 calculates the temperature differential between the freeze chamber temperature detected by a freeze chamber temperature detective means 21 and the set temperature for the freeze chamber 8 detected by a freeze chamber temperature-setting means 23 and from the temperature differential a revolution speed-calculating means 25 decides the revolution speed of the compressor 17 and an inverter circuit 26 operates the compressor 17 at the decided number of revolutions. The compressor is operated at the minimum revolution speed according to a minimum revolution speed command- transmitting means 43, at a preset time a timer 42 stops transmitting a revolution speed command, and the number of revolutions of the compressor 17, decided by a revolution speed-calculating means 25, is transmitted. This method makes a sudden liquid back less possible to occur.
