  • Method of manufacturing hot formed object, and device and method for continous high-frequency heating
    Publication number: 20050098926
    Abstract: Raw materials are portioned in a plurality of molds, which are continuously moved and transferred to a heating area by a conveyer. The heating area is divided into a plurality of sub-areas, each of which has power source means and power feeding means. The raw materials are heated and molded by applying high frequency to the molds from the power feeding means. Even if the heating apparatus is large, it is possible to restrain or prevent concentration of high-frequency energy since the heating area is divided into sub-areas.

  • Low electrostatic capacity wire-wound type ignition cable
    Patent number: 4435692
    Abstract: An ignition cable for supplying voltage to the spark plugs of an internal combustion engine, the cable having a low electrostatic capacity such that it does not produce noise in an FM radio frequency band. A central reinforcing string made of aramido-type fibers is covered by a ferrite core. A resistance wire having 8,000-14,000 turns/meter is wound onto the core. The assembly is then coated with a polyolefin insulation layer, a crossed-fiber reinforcement layer, and a silicon sheath, respectively.
