    • A thermistor element with positive temperature characteristic (PTC) has a planar ceramic member with a positive temperature characteristic of which the thickness is greater at its peripheral part than at the center part, decreasing either gradually or in a stepwise manner. Protrusions may be formed along its periphery. A PTC thermistor is formed with electrodes formed on both main surfaces of such a PTC thermistor, each electrode having a lower-layer electrode all over a main surface and an upper-layer electrode on the lower-layer electrode. The upper-layer electrode has a smaller surface area than the lower-layer electrode such that a portion of the lower-surface electrode is exposed at the periphery. The upper-layer electrodes may be formed at the center parts of the main surfaces, exclusive of the peripheral parts or where the protrusions are formed. The lower-layer electrodes may be mostly of Ni and the upper-layer electrodes mainly of Ag.
    • 具有正温度特性(PTC)的热敏电阻元件具有正温度特性的平面陶瓷构件,其周边部分的厚度大于中心部分的厚度,逐渐减小或逐步减小。 突起可沿其周边形成。 PTC热敏电阻器形成有形成在这种PTC热敏电阻的两个主表面上的电极,每个电极在整个主表面上具有下层电极,在下层电极上具有上层电极。 上层电极具有比下层电极更小的表面积,使得下表面电极的一部分在周边露出。 上层电极可以形成在主表面的中心部分,不包括周边部分或形成突起的位置。 下层电极大部分为Ni,上层电极主要为Ag。

    • A voltage control apparatus which is robust against disturbances such as variations in solar radiation amount around a solar cell, and has quick response, has a voltage detection unit (4) for detecting the voltage value of a battery power supply (1), a power conversion unit (2) for performing predetermined conversion of electric power supplied from the battery power supply, and supplying the converted electric power to a load or a commercial AC system (3), an output setting unit (5) for setting the output value of the power conversion unit on the basis of the voltage detection value, and a control unit (6) for controlling the power conversion unit on the basis of the output setting value. The output setting unit is constituted by a target voltage setting unit (51) for setting the target voltage value of the battery power supply, and an output calculation unit (52) for calculating the output setting value on the basis of the deviation between the voltage detection value and the target voltage value.
