  • Comparator circuit for generating binarized data
    Patent number: 8044686
    Abstract: A comparator circuit according to an embodiment of the present invention includes a comparator configured to compare an input signal voltage with a reference voltage obtained by smoothing the input signal by use of a resistor and a capacitor, and output a result of the comparison, a discharge circuit configured to compare a first addition signal which is obtained by adding a positive first voltage to the input signal voltage, with the reference voltage, and discharge the capacitor when the first addition signal is lower than the reference voltage, and a charge circuit configured to compare a second addition signal which is obtained by adding a negative second voltage to the input signal voltage, with the reference voltage, and charge the capacitor when the second addition signal is higher than the reference voltage.

  • Metal coated fiber and electroconductive composition comprising the same and method for production thereof and use thereof
    Patent number: 7166354
    Abstract: The present invention provides a metal coated fiber with excellent coating strength and corrosion resistance, and a conductive resin composition with excellent conductivity. A feature of a metal coated fiber of the present invention is that following provision of a metal coating on the surface of the fiber, heat treatment is conducted at a temperature greater than the crystallization temperature but less than the melting temperature of the fiber. Gradual cooling is preferably performed following the heat treatment. Furthermore, a conductive metal coating may be provided as the metal coating, and an additional corrosion resistant metal coating then laminated onto the surface of the conductive metal coating. In addition, a feature of a conductive resin composition of the present invention is that metal coated short fibers, formed by providing a conductive metal coating on the surface of a substrate fiber formed from a synthetic resin and then conducting heat treatment, are mixed into a substrate resin.
