Patents by Inventor Kyoichi Hasegawa

Kyoichi Hasegawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7527516
    Abstract: A portable electronic device includes an electronic component, a spring terminal extending from the electronic component to supply power to the electronic component, a circuit component having a power supply section contacting the spring terminal, and a stopper for restricting a movement of the electronic component. The spring terminal has a reversible deformation limit of elastic deformation. The stopper restricts the movement of the electronic component within the reversible deformation limit of the spring terminal. This portable electronic device prevents a spring pressure of the spring terminal from decreasing, hence supplying power to the electronic component stably.

  • Patent number: 5364253
    Abstract: A magnetic circuit component molding device for integrally molding a compound a center yoke with a ring-shaped magnet includes top and bottom press vertically arranged at opposed positions. A ring-shaped magnet is place on a bottom die between top and bottom press. The top and bottom press compress the compound against the ring-shaped magnet ring with a vertical pressure. A holder unit, separated in plural segments, having tapered outer circumferences is provided around the ring-shaped. A holder presser having a tapered inner circumference is mounted on the holder unit as tapered portions thereof are engaged together. A portion of the vertical pressure, when the top press compresses the compound, is transferred by springs 10 to the holder presser, and is amplified by the tapered portions and applied to the outer circumference surface of the ring-shaped magnet by the holder unit.
