    摘要: A variable resistor having a multi-layer resistive/conductive element is provided. The resistor has three electrodes, a resistive element connecting two of the electrodes and a sliding contact between the resistive element and the third electrode. The base of the resistor is provided with test areas. Each of the test areas contains a strip of the material used to form an individual layer in the multi-layer element. The test areas provide a convenient means for measuring the thickness of the individual layers in the multi-layer element without having to destroy the resistor.

    摘要: A tilt sensor for a vehicle steering shaft includes a base resistive element layer formed in an opposed contact with a base plate surface. A plural layer structure is provided with a protective resistive element layer constructed by at least one layer formed on the base resistive element layer and an uppermost layer of the volume inherent reistance of the protective resistive element layer is higher than the volume inherent resistance of the base resistive element layer. The volume inherent resistance of the protective resistive element layer is from 2 to 500 times the volume inherent resistance of the base resistive element layer.

    摘要: A variable resistor having a switching function includes a base plate, a first electrode formed on the base plate, a second electrode formed on the base plate, a third electrode formed on the base plate, and a fourth electrode formed on the base plate simultaneously with the formation of the second electrode. A resistive element connects electrically the first and the second electrodes, a first switching element is provided and includes two brushes which slide on the surfaces of the third electrode and the resistive element, respectively. A second switching element is movable together with the first switching element and includes two brushes which slide on the surfaces of the first electrode and the fourth electrode, respectively.
