Publication number: 20220365279Abstract: A coating removal tool removes a resin coating positioned at a distal end portion of a coated optical fiber. The coating removal tool includes a first holding part holding the resin coating positioned at the distal end portion, a second holding part configured to hold a base end portion of the coated optical fiber adjacent to the distal end portion, and a pedestal part configured to support the first holding part and the second holding part. The first holding part includes a heater for heating the resin coating positioned at the distal end portion and a blade for making a notch in the resin coating, and is provided to be slidable relative to the pedestal part. The second holding part is fixed relative to the pedestal part.Type: ApplicationFiled: October 19, 2020Publication date: November 17, 2022Applicant: SUMITOMO ELECTRIC OPTIFRONTIER CO., LTD.Inventors: Yoshinobu TODA, Hiroshi NAKAMURA

Patent number: 9075204Abstract: There is provided an optical connector construction tool, which is constructed as a single component, and is compact in size and simple, wherein the construction tool allows an operation of withdrawing a wedge to be more reliably performed, and a manufacturing costs to be reduced. The optical connector construction tool comprises a base plate, a wedge provided to a bottom surface of the base plate and inserted into a mechanical splice part of an optical connector, a pair of arms extending from both sides of the base plate, and protrusions projecting from the arms toward the base plate, the protrusions engaging with the bottom of the base plate and deflecting the base plate upward as a result of the arms being laterally brought together.Type: GrantFiled: August 3, 2009Date of Patent: July 7, 2015Assignee: Sumitomo Electric Industries, Ltd.Inventors: Daizo Nishioka, Yukihiro Yokomachi, Yoshinobu Toda, Yoshio Ukita

Patent number: 8478100Abstract: An optical cable gripping member which prevents the kinds of splicing devices from being diversified, thereby enabling reduction of the labor of component management and lowering of the production cost to be realized is obtained. In a cable gripping member 5 which is to be attached to a splicing device 1 to hold an optical fiber cable 121 from its outer sheath, a spacer 17 which fills a gap between one inner wall surface 15a of a tubular space 15 through which the optical fiber cable 121 is to be passed, and the spacer 17 in the tubular space 15 is formed monolithically with one end of the one inner wall surface 15a in a manner that the spacer 17 is attachable to and detachable from the one inner wall surface 15a. The spacer 17 is attached to or detached from the one inner wall surface 15a, thereby enabling a plurality of optical fiber cables of different sizes to be held.Type: GrantFiled: October 15, 2009Date of Patent: July 2, 2013Assignees: Sumitomo Electric Industries, Ltd., Nippon Telegraph and Telephone CorporationInventors: Yoshinobu Toda, Daizo Nishioka, Takayasu Yamauchi, Yukihiro Yokomachi, Kenichiro Ohtsuka, Keiichiro Sugimoto, Shinichi Niwa

Patent number: 8401356Abstract: An optical connector assembling jig and an optical connector assembling method includes an optical connection. The optical connector assembling jig includes a base and a guide. The base is provided in a longitudinal direction with an accommodation groove for accommodating an optical fiber, and a rear pressing member for restraining a rear part of the optical fiber accommodated in the accommodation groove. The rear part is set apart from an embedded fiber. The guide has a front holding portion for holding a front part of the optical fiber accommodated in the accommodation groove. The front part is near the embedded fiber, and the guide is capable of moving in the longitudinal direction. Moving the base toward the optical connector causes the intermediate section of the optical fiber to separate from the accommodation groove and bend. By moving the base further toward the optical connector, a buffered fiber in the optical fiber can be connected to the embedded fiber.Type: GrantFiled: April 30, 2009Date of Patent: March 19, 2013Assignee: Sumitomo Electric Industries, Ltd.Inventors: Daizo Nishioka, Takayasu Yamauchi, Yukihiro Yokomachi, Yoshinobu Toda, Yoshio Ukita

Patent number: 8283134Abstract: A cassette for fixing, embedding and slicing biological tissues includes a base sheet and a lid sheet formed of an elongated plastic sheet which is sliceable and has not less than predetermined strength. The base sheet has grooves as biological tissue receiving portions. The base plate and the lid sheet are formed by folding the plastic sheet along a fold line so that the lid sheet can be selectively opened and closed. Biological tissues are pressed against the bottoms of the grooves with pressing/retaining sponge members secured to the lid sheet at its portions corresponding to the respective grooves. In this state, the biological tissues are fixed by a fixing agent, and the cassette is dehydrated, infiltrated with paraffin as an embedding agent to embed the cassette, thereby forming a block including an embedding frame. The block is then sliced with a microtome to provide good biological tissue specimens.Type: GrantFiled: December 25, 2006Date of Patent: October 9, 2012Assignee: Kyoto UniversityInventors: Shigeru Amano, Yoshinobu Toda
