    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 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: In a method of making a poly-V grooved pulley from a circular flat plate of sheet metal of a predetermined thickness, the central portion of the parent flat plate is pressed to form a cup-shaped blank integral with a circular flat peripheral flange of the same thickness as that of the parent flat plate, the cup-shaped blank having a predetermined thickness thinner than that of the parent flat plate. The cup-shaped blank is pressed to form a hub wall, and the circular flat peripheral flange is drawn to form a cylindrical pulley flange wall. At the final stage, the cylindrical pulley flange wall is formed in its exterior periphery with a plurality of V-shaped grooves for a poly-V belt.

    摘要: A variable resistor with a switching function includes arcuate resistive layers and arcuate electrodes arranged alternately on a base plate. A protective layer is formed on the base plate adjacent to a first electrode and between the arcuate resistive layers. A gap separates the protective layer from the first electrode in order to electrically isolate the protective layer. A movable portion has brushes fixed thereto which slidably contact the resistive layers, the electrodes, and the protective layer. The protective layer serves as a lubricating layer to reduce the wear on the brush.
