Tadamasa YOKOI 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: 12109831
    Abstract: A laser processing device includes a setting device that sets an irradiation condition of laser light, and a first storage that stores the set irradiation condition. The setting device sets different irradiation conditions respectively for cells included in test cells. A verification device captures an image of the processing pattern and calculates luminance values for the cells respectively. The setting device sets at least one of the irradiation conditions for main processing, based on information on luminance values of the test cells extracted from the luminance values for the cells and based on the irradiation conditions set for the test cells.
    Type: Grant

  • Patent number: 10038296
    Abstract: A light amplifier according to an aspect of the present invention includes: a seed light source configured to generate a pulsing seed light; an excitation light source configured to generate excitation light; a light amplifying fiber configured to amplify the seed light by the excitation light and output the amplified light; and a control unit configured to control the seed light source and the excitation light source. The control unit has a mode to control the excitation light's power such that as a set value of a pulse width of the amplified light increases, the amplified light's peak energy increases within a threshold value at a minimum set value of the pulse width.

  • Patent number: 8837895
    Abstract: A fiber holder which can wind an optical fiber easily and accurately, and hold an optical fiber in a wound state is provided. The optical fiber is accommodated in the groove (introduction portion) formed on the fiber bobbin, after that, the bobbin cover is rotated in the rotational direction of the helical groove while the optical fiber is kept in contact with the cutout formed in the bobbin cover. With this, the optical fiber can be accommodated in the groove. Thus, the optical fiber can be wound easily and accurately, and the optical fiber can be held on the fiber bobbin.
