Disclosed is an electric apparatus comprising a housing with a door, a turntable arranged in the housing for rotating an object, a synchronous motor for driving the turntable, and a control portion for controllling the driving of the synchronous motor, the control portion having apparatus for storing the time required for the turntable to rotate once, apparatus for determining whether or not a time period which is approximately a natural number multiple of the time required for the turntable to rotate once, has elapsed since initiation of turntable rotation, and apparatus for stopping an operation for the rotation of the turntable on the basis of the determination that time, which is approximately a natural number multiple of the time required for one rotation of the turntable, has elapsed. When the synchronous motor is energized during only the time which is approximately a natural number multiple of the time required for the turntable to rotate once, the turntable stops after it rotates approximately a natural number of times. Accordingly, the object placed on the turntable is stopped in the same position within the housing as that at the time when the rotation of the turntable was initiated, so that the object can be easily taken out.

Electric apparatus with a controlled turntable

An electric cooking oven for use a normal cooking mode and defrost mode is provided which comprises a detector for detecting a temperature of a food body during cooking thereof, the detector comprising a thermistor which detachably attached to the food body to sense the temperature thereof. A circuit is provided for compensating the gradient of the output characteristics of the temperature detector to increase the gradient of the output characteristic curve of the resistance of the thermistor as a function of temperature in when the thermistor is operating in a temperature range in which it has a low accuracy of temperature sensing.
