摘要： The output of a first bridge circuit including as one component element a thermistor for detecting the temperature of a pan is compared with a preset value in a first operational amplifier. The first operational amplifier provides a low level output when the detected temperature is below a predetermined temperature. When this low level output is supplied to a second operational amplifier, the output thereof goes to a high level to turn on a transistor so as to energize a relay for passing current to a cooking heater. When a cooking end temperature is reached, the internal resistance of the thermistor is reduced, and as a result the output of the first operational amplifier goes to a high level, causing the output of the second operational amplifier to go to a low level. Thus, a warming heater is energized while the cooking heater is de-energized.

摘要： An electric apparatus involves a temperature sensor and a controlled circuit connected to an A.C. source to be sequentially controlled in accordance with the output from the temperature sensor. The control device comprises an auxiliary power source, a first control circuit for controlling the controlled circuit, and a second control circuit for supplying first control signals to the first control circuit, each being connected between control lines. The second control circuit involves an oscillator for producing clock pulses, a generator for generating reset pulses synchronized with the frequency of the A.C. source, a counter which counts the clock pulses and is reset upon receipt of the reset pulses, a control signal generator which processes an output signal from the temperature sensor to produce the first control signals, and circuit arrangements which, when a momentary power failure takes place in the A.C. source, impress the voltage of the auxiliary power source only on the second control circuit, thereby suppressing the initialization of the second control circuit and preventing the first control signal from being delivered to the first control circuit.

摘要： An electric rice cooker is disclosed which performs auxiliary cooking such as "twice cooking" by changing the operating time of auxiliary cooking in accordance with the actual cooking amount, immediately after the main cooking is completed. The actual temperature of a kettle which contains rice and water and which is detachably mounted in a thermal insulating frame is measured by a thermistor. Upon deenergization of an electric heater after main cooking is completed, the actual kettle temperature decreases. A time interval for the kettle temperature to go from a first temperature at the completion of main cooking to a second temperature is closely related to the actual cooking amount. The auxiliary cooking time interval is determined by a control circuit arranged in a case in accordance with the time interval described above.
