Kimiko Kawazoe 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).

  • Optical mirror and optical scanner and laser machining apparatus using the same
    Patent number: 6633422
    Abstract: A reliable galvano-mirror employed for laser machining is disclosed. The mirror is far reduced its weight for getting a higher rotation. On the rear surface of the mirror, a lightweight rib-structure, which is formed from a mirror support beam centered across the surface and some ribs extending from the beam, holds the mirror. Against a distortion occurred in rotating at high speed, the mirror is provided with a high rigidity. And the mirror is structured integrally with the motor shaft holder. Besides, a slit is formed between the rib disposed close to the holder and the support beam centered across the rear surface of the mirror. Providing slit enables to minimize a local distortion caused by a stress from fastening screws to attach the mirror to the motor shaft.
