Patents by Inventor Fumihiko Nakano

Fumihiko Nakano 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: 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.
    Type: Grant

  • Publication number: 20100183040
    Abstract: A laser source device includes an optical amplifier having an optical amplifying medium that is configured to amplify a seed beam when the seed beam and an exciting beam are entered, a seed beam source for emitting a laser beam as the seed beam, and an exciting beam source for emitting an exciting beam. The seed beam source emits a pulse beam as the seed beam during a predetermined principal irradiation period. The seed beam source emits a substantially continuous beam as the seed beam, having a smaller power than a peak power of the pulse beam during a supplemental irradiation period different from the principal irradiation period. The exciting beam source emits the exciting beam such that the power of the exciting beam is smaller during the supplemental irradiation period than the power of the exciting beam during the principal irradiation period.

  • Patent number: 4851266
    Abstract: A method of halogenating the outer and inner surfaces of a latex article such as a glove or girdle to different degrees thereby providing different slippery coefficient surfaces on the outside and the inside of the article within the need of powders, resins or exterior finishes and which results in less free chlorine atoms being released into the atmosphere.
