Patents by Inventor Mitsuo Hatada

Mitsuo Hatada 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).

  • Sensor device with coated electric wire shielding
    Patent number: 7145348
    Abstract: A coated electric wire is wound around a detection circuit in a planar manner for the purpose of electrostatic shield. This winding is performed, for example, spirally in a single layer. In the case where there are further provided a detection circuit board including a detection circuit and a cylindrical case, the coated electric wire is wound around the detection circuit board in a planar manner, wherein the direction of the axis of the cylindrical surface accords with the direction of the axis of the case. Consequently, there can be provided a sensor device in which the detection circuit can be electrostatically shielded with ease.

  • Proximity sensor with improved positioning accuracy for detection coil peripheral members
    Patent number: 6801113
    Abstract: A proximity sensor according to the present invention includes protrusions that are provided on a wire-winding drum of a coil spool around which a lead wire of a detection coil is wound, that protrude toward the center from not less than three points distributed in the range exceeding a semi-circle on the circumference of the wire-winding drum and that are elastically brought into contact with the shaft of the core, respectively, thereby coaxially positioning the coil spool and the shaft of the core.
