Title: Penetration type hermetic terminal for optical fiber
Inventor: NAKASEKO MASARU
IPC: H02G15/013
Filed: 1991-08-05
Abstract: PURPOSE:To eliminate the need for optical axis adjustment without generating a light transmission loss in a hermetic terminal part by removing the double coating layers provided on the outer side of an optical fiber and adhering and fixing the exposed optical fiber by an epoxy resin in the metallic pipe. CONSTITUTION:The optical fiber 2 exposed by removing the primary coating layer 3 and the outside coating layer 4 in the intermediate part of the optical fiber cord 1 is housed in the metallic pipe 5 consisting of a stainless steel, etc. The epoxy resin 6 is packed into the spacing between this metallic pipe 5 and the optical fiber 2 to adhere and fix the optical fiber 2. The metallic pipe 5 and the end of the outside coating layer 4 of the optical fiber cord 1 are adhered and fixed by the epoxy resin 10. The hermetic terminal formed in such a manner is held by the epoxy resin packed in the metallic pipe. The hermeticity between the outside coating layer and the metallic pipe is maintained by the epoxy resin applied on the outer side thereof and the hermeticity between a body flange and a housing is maintained by an O-ring to be inserted into a packing groove.

Title: Cleaning device
Inventor: SENBA HISAAKI

Filed: 1984-10-23
Abstract: PURPOSE:To prevent the balance of an image from being lost and to obtain stable images over a long period by sequentially changing the thickness of a toner layer adhered to a sliding roller in the axial direction of the sliding roller. CONSTITUTION:The end edge 5c of a scraper member 5b fitted to one side of a supporting member 5b which is abutted upon the sliding roller is formed like a center-recessed shape so that the width of the member 5a is gradually reduced from both the ends to the center, i.e. from l1 to l2 (l1>l2). When the formed end edge is abutted upon the sliding roller 4, the member 5b is deeply pressed against the sliding roller near both the end parts and softly pressed against it at the center. Consequently, the scraping state of toner from the surface of the sliding roller is different in the center and both the end parts, so that the quantity of toner on the part passing through the scraper 5 and advancing again to the surface of the photosensitive body is much on the center part than that on both the end parts and the toner layer can be made thick. Consequently, the toner layer can be ground as uniform as possible over the whole width of the photosensitive body.

IPC: H02P29/00
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide an electrically-driven reel for fishing, capable of winding up a fishline at a fixed reeling speed without changing the set reeling speed even if load to the fishline is changed in winding up the fishline and not stopping the winding by a motor even if a reeling operation by a handle is added. SOLUTION: This electrically-driven reel for fishing has a spool which is rotatably held between a right and a left frames and which is rotated by a motor or by the motor and manually by a handle. A DC voltage to be applied to the motor is controller by a digital control means so as to make the difference between the number of revolutions of the spool to be changed by the variability of load applied to a fishline wound on the spool and the number of revolutions of the spool corresponding to a preset reeling speed zero. Consequently, the revolution speed of the spool is controlled to be constant. When an operation by a handle is added, a digital control is interrupted, the driving stage of the motor in the operation is maintained and the motor continues the revolution. When the operation by the handle is finished, the digital control is resumed.
