  • Resistor excellent in micro-linearity characteristic and variable resistor using the same
    Patent number: 6507271
    Abstract: A resistor is provided that is made by laminating at least two resistive layers, where these resistors have conductive particles held in a binder resin. The resistors are laminated such that a top resistor covers a bottom resistor, and a surface of the top resistor is exposed. The resistivity of the top resistor is made smaller than that of the bottom resistor. The top resistor contains carbon fiber and carbon black, where the central particle size of the carbon fiber ranges from 3.5 to 9.0 &mgr;m. The resistor has excellent durability and micro-linearity characteristics. The resistor may also be used as a variable resistor.

  • Resistor excellent in micro-linearity characteristic and variable resistor using the same
    Publication number: 20020075130
    Abstract: The invention provides a resistor excellent in micro-linearity and further, the durability to sliding as well as a high-precision variable resistor using the resistor and having a long life. A lower layer and an upper layer of the resistor are laminated, the surface of a resistor on which a slider is slid is formed of the upper layer and resistivity of the upper layer is smaller than that of the lower layer.
