    摘要: A heating element comprises a resistor comprising a plurality of fine particles (1) or thin films (4) having a negative temperature coefficient of electrical resistance, and highly resistant region layers (2) interposed between the fine particles or thin films, at least two separate electrodes (3) arranged in contact with different particles or layers of the resistor, and means (5) for applying across said electrodes which are not lower than a frequency corresponding to point B of the complex impedance characteristic of the resistor when graphed in the manner shown in Figure 4 hereof. This heating element has the following merits: that it can be formed into an optional shape, is low in the power consumption, can be rapidly heated, has temperature self-adjusting performance and temperature detecting performance and is excellent in the durability.

    摘要: The disclosed oxygen concentration detector includes at least one oxygen concentration cell (10, 12, 13) and at least one oxygen-ion-conducting solid electrolyte (10, 11), means (15) for applying an alternating current of a specific frequency to the oxygen concentration cell so as to raise the temperature thereof, and means (18) for applying a direct current to the oxygen-ion-conducting solid electrolyte (11) so as to control the oxygen partial pressure at one or two electrodes (13) of the oxygen concentration cell. Each body (10, 11) consists of a plurality of fine grains having negative resistance properties and high resistance layers separating the grains. The AC source (15) is operated in a frequency range such that the impedance of the bodies is largely independent of the interface capacitance between the bodies and their electrodes.

    摘要: The disclosed oxygen concentration detector includes at least one resistive body (10) and at least one semiconductor (9) whose resistance varies with oxygen partial pressure, and means (13) for applying via electrodes (3. 4) an alternating current of a specific frequency to the resistive body (10) so as to raise the temperature thereof, which resistive body (10) is adapted to heat the semiconductor (9). The means (12) is openable at frequencies suffi- cientiy high that the impedance of said resistive body (10) is largely independent of the interface capacitance between the electrodes (3. 4) and the body (10). Means (16. 17. 18) are provided to measure the resistance of the semiconductor (9).
