摘要： PROBLEM TO BE SOLVED: To eliminate the stopping of heating on the way of cooking even while securing safety against overheating. SOLUTION: A stove is provided with a gas amount regulating lever position detecting unit 23 for detecting the position of a gas amount regulating lever for regulating the amount of fuel gas supplied to a gas burner. The amount of gas for supplying to the gas burner is detected in two stages based on the position of the gas amount regulating lever position detecting unit 23 and when the amount of gas is large, a timer 31a having a short time limit is employed to count a limited time while another timer 31b having a long time limit is employed to count the limited time when the amount of gas is small. When the limit time of either one of the timers 31a, 31b is finished, a safety valve 11 is closed to extinguish the fire of the gas burner.

摘要： PROBLEM TO BE SOLVED: To provide a display device having a battery as its power source, capable of restraining flickering of a light emitting element, irrespective of the type of the battery when the voltage of a power source consisting of the battery changes rapidly. SOLUTION: When an appliance plug switch SW is turned on, a control part 3 turns on/off a solenoid valve 5 for temperature control, and compares the voltage difference between both detected voltages of a power source 1 by a voltage detecting circuit 4 under respective conditions with a prescribed threshold voltage to discriminate the type of a battery. First and second control signals, associated with the on/off operation of the solenoid valve 5 for temperature control, are determined so that current flowing through a light-emitting diode, LED 6 may be almost constant, irrespective of whether the solenoid valve 5 for temperature control is turned on or off according to the type of a battery. An LED drive circuit 7 is controlled by the second control signal to light the light-emitting diode 6. In turning on the solenoid valve 5 for temperature control, the first control signal starts controlling of the LED drive circuit 7, while in turning off the solenoid valve 5 for temperature control, the second control signal starts controlling of the LED drive circuit 7.
