Yuuji Koganezawa 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).

  • Coil winder and wire winding method
    Patent number: 6622954
    Abstract: This invention provides a coil winder which can shorten the time required to wind coils. The coil winder has a nozzle for feeding out a wire, a stator support base, a head for supporting the nozzle free to move radially relative to the rotation axis of the stator support base, a head support shaft which supports the head and extends axially, a head support shaft displacement mechanism for moving the head support shaft to and fro axially, a head support shaft rotating mechanism for rotating the head support shaft around the axis, a traverse shaft which passes through the head support shaft, a traverse shaft rotating mechanism for rotating the traverse shaft, and a nozzle displacement device for displacing the nozzle radially relative to the axis due to the relative rotation of the traverse shaft with respect to the head support shaft. Motors provided for the head support shaft rotating mechanism and the traverse shaft rotating mechanism are supported by a frame.
