Abstract: PROBLEM TO BE SOLVED: To provide a heater for speedily heating a beverage or food in a container kept at a temperature avoiding quality deterioration. SOLUTION: This heater is provided with a tank 1 for storing a liquid at a high temperature, a liquid flowing means 10 for making the liquid flow, a container holding means 3 for holding a container 2 housing a beverage or food and a rotation means 4 for rotationally moving the container 2 within the tank 1. Thus, the liquid at a high temperature being a heat source for heating the beverage or food can be made to flow within the tank and the container 2 can rotationally be moved in the direction of improving a relative speed between the flowing liquid and the container 2 in the flowing liquid at the high temperature being the heat source. Thus, a heat transfer coefficient between the liquid in the tank 1 and the wall surface of the container 2 can be improved and moving of heat from the liquid to the container wall is quickened.

Abstract: PROBLEM TO BE SOLVED: To obtain an operation controller for a refrigerator for setting a demagnetizing current protective value of a DC motor at each temperature condition of a place where the motor is installed, by providing a circuit for comparing a current value with a demagnetizing current protective value, a circuit for controlling an inverter, and an interface. SOLUTION: A comparator 4 compares a current value voltage-converted by a current detector 3 with a demagnetizing current reference value V1 set by an indirect type demagnetizing current setter 5. The setter 5 has resistors 5a to 5c and a thermistor 5d. Temperature condition of a place where the refrigerator is installed is detected by the thermistor 5d, which, in turn, sets a demagnetizing current set value V1 responsive to the detected temperature. A composite circuit 8 of a controller 6 combines a control signal output from a signal generator 7 with an output signal from an AND gate 8d. An interface 8 transmits the output signal of the controller 6 to semiconductor switches 2a to 2f of an inverter circuit 2.

Abstract: PROBLEM TO BE SOLVED: To enable an influence of failure of energization in the case that a load torque is high to be reduced by a method wherein a load torque of a DC electric motor at the time of energization is detected by a torque-up means in reference to a temperature at an upper part of a cooler device and the energization is carried out in response to an energization sequence pattern corresponding to the load torque from the beginning in operation. SOLUTION: When a refrigerator 30 is energized, an energization sequence control means 13 and a synthesizing means 21 are connected by an operation mode changing-over means 20, an energization sequence pattern A stored in an energization sequence pattern memory means 14 is outputted to the energization sequence control means 13 from the torque-up means 18 and then a compressor 5 is operated under an energization sequence pattern showing the most lowest output torque. Then, it is judged by a lock sensing means 17 whether or not the compressor 5 is locked and in the case that the locked state is found, the energization sequence pattern B stored in the memory means 15 is outputted to the energization sequence control means 13 by the torque-up means 18 and then the compressor 5 is operated under an energization sequence pattern having a larger output torque.

When it is equal, the pressure condition of the refrigerating cycle 2 is judged that it is stabilized and a compressor 5 is driven, however, when a pressure difference is big and the pressure condition is unstable, the ambient temperature T2 of a refrigerator is detected by an ambient temperature sensor 17, a period of time until the condition of high and low pressure of the refrigerating cycle becomes stable at the temperature T2 is determined by a start waiting time determining means 18 and the operation mode of the compressor is changed into a mode, in which the compressor 5 is not started. During this period, a waiting time lamp 20 is lighted by a timer count means 19 and the stabilized driving of the compressor is effected by a motor controller 7 for compressor after finishing the waiting time while these operations are repeated thereafter.
