摘要： A positive temperature coefficient thermistor is prepared from a sintered body of a ceramic material composition which has as a substrate BaTi0₃ with metallic oxide and has, in a predetermined voltage range, a voltage-current characteristic defined by the following equation: Vx + Iy = a ̲ wherein a is a constant value, Vx is a voltage on an axis of abscissa and Iy is a current on an axis of ordinate in a cartesian coordinate, said voltage range extending from a predetermined value to a value at least twice as much as the predetermined value so that when a voltage in said voltage range is applied to the sintered body, the sintered body provides heat at a substantially constant value. Thus, when the present invention is used in countries or areas in which commercial voltages of 110 V and 220 V are used, almost certain temperature can be obtained without changing voltage by a transformer.

摘要： A device body is equipped with a heater unit (3) and a thermal evaporating agent (9) is filled in a tank (6), and a leading end of a core (8) for sucking up the thermal evaporating agent which is inserted is the tank (6) is inserted into the heater unit (3). The heater unit (3) is in an annular shape and is incorporated with a transformerless exothermic body (10). The transformerless exothermic body (10) is a positive temperature thermistor and the voltage-current characteristic thereof has a region, over the range of at least 100V to 240V of applied voltage, which satisfies the conditions of Vx + Iy = a (a is constant) in orthogonal coordinates in which a longitudinal axis is a voltage Vx and a lateral axis is a current Iy. Therefore, even though the applied voltages are 100 V and 240 V, the change of consumed current, P=VI is small and there causes no difference in their exothermic temperatures in the range of the applied voltages of 100 V to 240 V. Thus, even though the applied voltage is 100 V or 240 V, there causes no difference in consuming time of the thermal evaporating agent.
