摘要： A cleaning tool for cleaning optical fiber connectors exposes a cleaning sheet in a window of the case. A winding pulley is operable to wind the cleaning sheet upon rotation at a constant pitch. A rotation mechanism, that is operated by a lever, rotates the winding pulley. The case is constructed of a first front plate and a second front plate which are closed off by a perimeter wall along their outer circumference. The case has an open portion in a part of the perimeter wall, and the lever is disposed in the open portion in an inclined orientation.

摘要： A ferrule for optical fibers transmitting linearly polarized light capable of preventing deterioration and fluctuation of the extinction ratio. The ferrule incorporates at least two paths connecting a region in a vicinity of an end of a puncture for an optical fiber inside the flange portion with outside of the ferrule. These paths effectively enable the removal of air in such a region which could have caused an extraneous stress on the optical fiber resulting in deterioration of the extinction ratio. An optical fiber connector using this ferrule is also disclosed.

摘要： In the production of a hollow cast article having a slit, the release of a hollow cast product from a mold is carried out while opening the hollow cast product. In one embodiment, a core provided with recessed parts (or projected parts) formed in a slit forming part (or an outer peripheral part) is used and the drawing out of the core from the hollow cast product is carried out while opening the hollow cast product by means of the recessed parts (or projected parts) mentioned above. By such a method, a hollow cast article having a slit and projected parts (or recessed parts) formed in a slit part or/and an inner peripheral part thereof is obtained. In the case of the use of a core having a slit forming part of a taper-shaped ridge of which width gradually decreasing from a large width at one end to a small width at the other end, the core is drawn out from the hollow cast product in the direction to the other end of small width to open the hollow cast product by means of the slit forming part of the taper-shaped ridge.

摘要： In a plug-in connector for connecting elements mounted on a backage board to other elements arranged on a back wiring board disposed perpendicular to the package board, the guide pin and the connector housing fixing screw are formed integral with each other to realize a floating connector coupling structure which is high in mounting efficiency and precision and small in size. Further, the plug-in connector can connect two different, optical and electrical connectors. Further, there is disclosed a novel optical connector plug whose radial eccentricity direction can be matched with that of a mated optical connector jack with an optical fiber aligning jig to minimize the optical fiber coupling power loss.

摘要： A conversion adapter to be used for connecting opposed optical connector ferrules having different diameters is formed of an amorphous alloy possessing at least a glass transition region, preferably a glass transition region of not less than 30 K in temperature width. Particularly, the amorphous alloy of M1—M2 system or M1—M2—La system (M1: Zr and/or Hf, M2: Ni, Cu, Fe, Co, Mn, Nb, Ti, V, Cr, Zn, Al, and/or Ga, La: rare earth element) possesses a wide range of &Dgr;Tx and thus can be advantageously used as a material for the conversion adapter. Such a conversion adapter can be manufactured with high mass-productivity by a mold casting method or molding method.

摘要： To microscopically clean the ferrule end surface of an optical connector simply, uniformly and securely, the optical connector cleaner comprises a cleaning cloth woven with ultrafine fiber less than 0.1 denier; a casing formed with at least one opening for protecting the cleaning cloth from dust; and a mechanism for shifting the cleaning cloth exposed in the opening for cloth renewing, after the ferrule end surface has been rubbed with the cleaning cloth for cleaning. Further, it is preferable to provide an elastic member under the cleaning cloth for applying a constant cleaning pressure against the cloth and a guide member over the cleaning cloth for securely cleaning the ferrule end surface. The cloth shift mechanism is operated manually by the user or automatically by a motor. A holder jig holds the optical connector to facilitate cleaning of the ferrule end surface. The holder jig supports the optical connector such that the ferrule projects from the holder jig.
