Patent number: 10001604Abstract: A connector-incorporating plug contains a connector to be inserted into and connected to an adapter in a receptacle and is connected to the receptacle. The connector-incorporating plug includes a housing that is located at a back-end side of the connector in a direction of insertion, to hold the connector, a spring pressing the housing in the direction of insertion, a holder that is located in front of a flange portion formed on the housing and that is mounted to the housing, and a shell member. The holder is pressed by the spring through the flange portion to butt against a projection formed on the inner wall of the shell member, and is kept there. The housing is movable with respect to the holder only along a first axis orthogonal to the direction of insertion. The holder is movable with respect to the shell member only along a crossing axis.Type: GrantFiled: May 20, 2015Date of Patent: June 19, 2018Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Yuichi Koreeda, Hideto Shimazu, Osamu Imaki, Hideo Sugimoto, Naoki Katagiyama, Masaki Ishiguro, Yasutaka Hiroki

Patent number: 9904019Abstract: In an optical-connector-incorporating plug accommodating and holding an optical connector in a barrel at a front end thereof and accommodating, in the barrel, an extra length portion of an optical fiber extending from an optical cable to the optical connector, the extra length portion bends as the optical connector is moved toward a back end of the barrel when the optical connector is connected to a mating receptacle; the distance from the position where the optical connector is held to the outer wall of the barrel depends on the direction, among the directions orthogonal to the direction in which the optical connector is moved; and a guide portion guiding the bend of the extra length portion in a direction other than the direction where the distance to the outer wall of the barrel is the shortest is formed in the barrel. The optical-connector-incorporating plug can be reduced in size.Type: GrantFiled: May 29, 2015Date of Patent: February 27, 2018Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Yuichi Koreeda, Hideto Shimazu, Osamu Imaki, Hideo Sugimoto, Naoki Katagiyama, Masaki Ishiguro, Yasutaka Hiroki

Patent number: 9470848Abstract: A receptacle has a backward-movable floating mechanism and includes a receptacle-side slider, a first lock mechanism (first ball) functioning to couple and fix the receptacle to a plug, and a second lock mechanism (second ball, indentation) that prevents the backward movement. The plug includes a plug-side slider and an indentation. When the plug is inserted into the receptacle, the plug-side slider is prevented from moving forward by the first ball and only the housing of the plug moves forward. When connection between male and female members is complete, the first ball fits into the indentation and the plug-side slider moves forward to lock the first ball. The receptacle-side slider is pushed backward by the plug-side slider, the second lock mechanism is unlocked and the housing of the receptacle is moved backward by the floating mechanism.Type: GrantFiled: October 18, 2013Date of Patent: October 18, 2016Assignee: JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Osamu Imaki, Hideto Shimazu

Patent number: 8956057Abstract: An optical fiber connector comprises a ferrule having a rear end, a chuck located rearward of the ferrule, a ring having a front end, and a coil spring. The ring is attached to the chuck so as to surround the chuck. The optical fiber connector holds an optical fiber which is inserted from a rear end of the optical fiber connector. In detail, when the optical fiber is inserted into the optical fiber connector, an end of the optical fiber passes through the chuck to be accommodated in the ferrule. The coil spring presses the ring forward (toward the ferrule) so that the chuck is squeezed to hold the inserted optical fiber. When the ring is moved rearward by a stopper inserted between the rear end of the ferrule and the front end of the ring, the chuck is released to release the optical fiber.Type: GrantFiled: November 29, 2012Date of Patent: February 17, 2015Assignees: Japan Aviation Electronics Industry, Limited, Asahi Glass Company, LimitedInventors: Osamu Imaki, Hideto Shimazu, Yuji Watanabe, Minoru Sekine

Patent number: 7582497Abstract: A micro-optic device including a complicate structure and a movable mirror is made to be manufactured in a reduced length of time. A silicon substrate and a single crystal silicon device layer with an intermediate layer of silicon dioxide interposed therebetween defines a substrate on which a layer of mask material is formed and is patterned to form a mask having the same pattern as the configuration of the intended optical device as viewed in plan view. A surface which is to be constricted as a mirror surface is chosen to be in a plane of the silicon crystal. Using the mask, the device layer is vertically etched by a reactive ion dry etching until the intermediate layer is exposed. Subsequently, using KOH solution, a wet etching which is anisotropic to the crystallographic orientation is performed with an etching rate which is on the order of 0.1 ?m/min for a time interval on the order of ten minutes is performed to convert the sidewall surface of the mirror into a smooth crystallographic surface.Type: GrantFiled: February 22, 2008Date of Patent: September 1, 2009Assignee: Japan Aviation Electroncis Industry LimitedInventors: Yoshichika Kato, Satoshi Yoshida, Keiichi Mori, Kenji Kondou, Yoshihiko Hamada, Osamu Imaki
