Title: Production of optical fiber coupler
Inventor: NAKAMURA MASASHI
IPC: G02B6/28
Filed: 1990-11-30
Abstract: PURPOSE:To prevent drop of production yield due to crosstalk by bringing the terminal faces of both optical fibers held by an optical fiber coupling evice into contact with each other, to couple with each other by melting both, and then, melting parallelled coupled fibers and stretching them to fix a bundle of the plural fibers into one body, and thus to form a coupled, stretched, and bundle-united optical fiber. CONSTITUTION:Each optical fiber is rotated by a rotating member Y and correcting the polarizing axis of each fiber with each terminal face brought into contact with each other and the relation of the polarizing axes between this and parallelled fibers are set. Each fiber bundle 11, 12 is fixed and each terminal end face is melted and coupled by coupling means 17a, 17b. The melted part is stretched by enlarging a distance of first and second bundle holding stages 13, 14, thus permitting the plural fibers to be united into a single fiber and stretched in the melt-coupled part having a taper form, and accordingly, drop of the production yield due to deterioration of cross-talk is prevented.

Title: Double bearing reel
Inventor: KATAGIRI NAOHISA
IPC: A01K89/033
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a double bearing reel provided with a brake mechanism for making brake force act on free rotation in the fishing line delivery rotation of a spool and inhibiting the brake force from acting on the fishing line winding rotation of the spool rotated by the rotation of a handle. SOLUTION: A contact amount to a main shaft 4 is increased and decreased by compressing and restoring a coil spring A2 wound around a tapered surface formed at a spool shaft 4 in a contact state and resistance force is made to act on the spool shaft 4 and the brake force is imparted to the rotation of the spool 3 by the reduction of the winding diameter of the coil spring A2 accompanying the fishing line delivery rotation of the main shaft 4. Also, for the fishing line winding rotation of the main shaft 4, since the winding diameter of the coil spring A2 is widened, the resistance force does not act on the main shaft 4.

Title: Travel amount measuring device
Inventor: TOYOKAWA MITSUMASA
IPC: G06F17/40
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To measure travel amount of sheetlike medium to be measured accurately by measuring at which position of read-out picture element of a CCD camera the center of horizontal rule of the medium to be measured is and moving the medium to be measured by one pitch. SOLUTION: A horizontal rule is recorded on paper 8 by a printer 4, and the paper is conveyed until this record reaches a paper guide face 7A and is stopped. Next, a CCD camera 17 is moved together with a length measuring machine 12 by driving a motor 13 to a position where horizontal rule of the paper 8 can be visually checked through an ocular lens 18 of the CCD camera 17. When horizontal rule can be visually checked on the paper 8, the motor 13 is stopped, the horizontal rule on the paper 8 is photographed by the camera 17, and the horizontal rule which is photographed is image-processed by a control means 24. Then, the paper is conveyed by one pitch to photograph the horizontal rule again.  Consequently, since two coordinates of the horizontal rule before and after the paper 8 is conveyed by one pitch are detected, it is possible to calculate the actual conveyance amount of the paper 8 by subtracting it by the control means 24.
