Patents by Inventor Hidemitsu Sugawara

Hidemitsu Sugawara 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 axis adjusting method, optical module producing method, optical axis adjusting apparatus, and optical module
    Patent number: 7614801
    Abstract: An optical axis adjusting method for adjusting a tilt angle of an optical axis in two regions optically coupled in a holding member includes the steps of: roughly adjusting the optical axis by irradiating a first region on the holding member with a laser beam; and finely adjusting the optical axis by irradiating a second region on the holding member with a laser beam. One of the two regions is set as a reference point. The first region is located closer to the reference point, while the second region is located further from the reference point.
    Type: Grant
    Filed: November 21, 2007
    Date of Patent: November 10, 2009
    Assignee: Eudyna Devices Inc.
    Inventors: Haruyoshi Ono, Hidemitsu Sugawara
