    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.

    摘要： An electrical resistor having a resistance value and capable of withstanding high power surges, utilizing a thick film deposited on a substrate and trimmed with one or more cuts configured to maintain a level of current crowding while increasing the resistance value of the resistor. A surge resistor can be modified in a similar fashion.

    摘要： This patent discloses apparatus for altering the electrical characteristics of electrical and electronic components by trimming or abrading, the rate of abrading being variable and is responsive to changes in the electrical characteristics of the components during the abrading operation. Electrical components that have electrical characteristics that may be altered by the abrading apparatus include resistors, capacitors, inductors, semiconductive devices, and photocells. The apparatus includes electrical circuitry for both accurate control of the rate of abrasion and enabling production of electrical and electronic components to predetermined characteristics with unusually close manufacturing tolerances. The circuitry includes a highly sensitive Kelvin bridge at each abrading station, the circuitry being programmable for trim pretesting, control of the rate of abrading, and post-testing. The circuitry may also be programmed to abrade a discrete component to predetermined tolerances, and/or abrade one of a pair of components to a predetermined ratio of the electrical characteristic of one component to the electrical characteristic of the other of the pair. Additionally, the circuitry may be programmed to abrade one component in a connected closed loop of components to predetermined tolerances, for example ''''in circuit'''' abrading. The mechanical arrangement of the apparatus provides for sequentially abrading multiple electrical and electronic components which may be positioned on both the upper and lower surfaces of single insulating members such as ceramic substrates. The apparatus is fully mechanized for rapid processing of a high production product through sequential abrading stations and includes stations for rejecting out-of-tolerance components.
