  • Casting apparatus and method therefor
    Patent number: 7210516
    Abstract: A casting apparatus including a die that contains a molten metal that is poured via an opening section disposed above the die. The casting apparatus also includes a heater disposed above the die, and a gas supplying structure for supplying an inter gas to a surface of the molten metal. The casting apparatus further includes a lid disposed between the surface of the molten metal and the heater, and a lid moving structure for moving the lid to the die relatively so as to control the opening amount of the opening section above the die.

  • 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.
