摘要： A resistor element has a ceramic body with a first outer electrode and a second outer electrode formed on its mutually opposite externally facing end surfaces and a plurality of mutually oppositely facing pairs of inner electrodes inside the ceramic body. Each of these pairs has a first inner electrode extending horizontally from the first outer electrode and a second inner electrode extending horizontally from the second outer electrode towards the first outer electrode and having a front end opposite and separated from the first inner electrode by a gap of a specified width, these plurality of pairs forming layers in a vertical direction. The gap of at least one of these plurality of pairs of inner electrodes is horizontally displaced from but overlapping with the gaps between the other pairs of inner electrodes. For producing such a resistor element, the distance of displacement is set according to a given target resistance value intended to be had by the resistor element. Alternatively, the thickness of those portions of the ceramic body between at least one of mutually adjacent pairs of the inner electrodes is different from the thickness of the portions of the ceramic body between the other mutually adjacent pairs of the inner electrodes.

摘要： A chip thermistor has a pair of outer electrodes opposite each other with a specified distance in between on one of the surfaces of a thermistor element and an inner electrode extending inside the thermistor element so as to overlap these outer electrodes in the direction perpendicular to the surface on which the outer electrodes are formed. An electrically insulating layer is preferably formed on the same surface as and between the pair of outer electrodes. Each of the outer electrodes may be formed with two or more layers, the outermost of the layers being of gold. The resistance value of such a chip thermistor can be adjusted by abrading at least a portion of the edges of the thermistor element together with portions of the outer electrodes.

摘要： A charge completion detector comprises a thermoelectric detecting element outputting a thermally generated electromotive force in correspondence with the rise of temperature incidental to the completion of charging a secondary cell, and detecting means electrically connected to the thermoelectric detecting element for detecting the thermally generated electromotive force generated in the thermoelectric detecting element. The thermoelectric detecting element comprises a base material of semiconductive ceramics and a plurality of pairs of electrodes formed spaced apart from each other by a prescribed distance on the base material for forming hot junctions and cold junctions. A heat radiating member is thermally coupled to the cold junctions of the base material. The temperature of the hot junction side thermally coupled to the secondary cell will be approximately the same as that of the secondary cell while the temperature of the cold junction side is kept at an environmental temperature. The rise of temperature is detected based on the change of the thermally generated electromotive force based on the difference between the temperatures of the hot junctions and cold junctions.
