Abstract: A mirror device includes a mirror (153) which is supported to be pivotable with respect to a mirror substrate (151), a driving electrode (103-1-103-4) which is formed on an electrode substrate (101) facing the mirror substrate, and an antistatic structure (106) which is arranged in a space between the mirror and the electrode substrate. This structure can fix the potential of the lower surface of the mirror and suppress drift of the mirror by applying a second potential to the antistatic structure.

Abstract: An optical connector has a ferrule comprises of a cylindrical body for supporting an optical fiber, and a flange member having an end portion connected to a first end of the cylindrical body and a flange part projecting from the end portion. A holding member supports the ferrule and has an engaging part. A rotation positioning part is formed in the flange part of the flange member for positioning the flange part relative to the holding member to provide a first clearance between the rotation positioning part and the engaging part of the holding member for restricting rotation of the ferrule about the fiber optical axis relative to the holding member. A rotation allowing part is formed in the flange part of the flange member and spaced from the engaging part of the holding member to provide a second clearance therebetween greater than the first clearance for allowing rotational movement of the ferrule so as to permit the ferrule to incline in a direction transverse to an axis of the optical connector.

Abstract: The object of the present invention is to provide a highly reliable optical fixed attenuator and the manufacturing process thereof being free of the conventional cumbersome processes including the process for inserting the optical fiber into the ferrule and fixing thereto. In the present invention, the surface of an optical fiber is metalized to serve as an electrode of the electroforming process so that a metal layer to serve as the ferrule 11 is directly formed over the outside surface of the optical fiber 10, and, as a result, a long ferrule, wherein the optical fiber 10 and the metal layer are fully integrated, is made available, whereby an optical device to constitute the desired optical fixed attenuator can be obtained by simply cutting such a long ferrule to any desired length.

Abstract: LAN device and tools can be connected only by optical fiber cables without providing a space for additional LAN devices and tools and changing an electric connector interface of the LAN devices and tools already established.

Abstract: Provided is a PC connector to be removed of useless stress during attached/detached thus being stably attached/detached. A flange part is provided in a polygonal or disk form circumferentially projecting on the flange member at a tip side thereof. In a holding part holding the flange member, an engaging part is formed axially of the optical fiber and in a predetermined engaging width. The flange part has a predetermined clearance to the engaging part at an axial tip side thereof. A rotation positioning part restricts a movement in rotational direction of the flange part. A rotation allowing part is provided to form, on a rear-end side of the rotation positioning part, a clearance greater than the clearance of between the rotation positioning part and the engaging part.

Abstract: LAN devices and tools can be connected by only optical fiber cables without providing a space for additional LAN devices and tools and changing an electric connector interface of the LAN devices and tools already established. Heat radiation produced in a connector can be effectively discharged and electromagnetic wave can be prevented from radiating to an exterior of the connector.

Abstract: In a pin-board matrix switch X- and Y-direction patterns are arranged in the X and Y directions to constitute a matrix. Crosspoint holes are formed at the crosspoints between the X- and Y-direction patterns. Each crosspoint hole has contacts formed therein. The contacts are connected to the patterns. A connecting pin has contact springs. The connecting pin is selectively inserted into the crosspoint holes to electrically connecting the contacts of the X-direction patterns and the Y-direction patterns which are adjacent to each other in the Z direction. Insulating members are arranged between the X- and Y-direction patterns. At least one pair of the X-direction patterns and the Y-direction patterns is constituted by first and second wiring layers arranged in the Z direction via insulating members.

Abstract: A matrix switching device includes a matrix board and a connecting pin. X-conductor patterns are arranged in parallel with each other on one surface of the matrix board, and Y-conductor patterns are arranged in parallel with each other on the other surface. Both the patterns are arranged in a matrix form. At each crossing point of the both patterns, a through hole having conductive portions respectively connected to the X- and Y-conductor patterns and an intermediate isolation portion for interrupting conduction between the conductive portions is formed in the matrix board. The connecting pin includes conductive portions respectively electrically connected to the X- and Y-conductor patterns through the conductive portions of the through hole upon insertion of the connecting pin into the through hole.

Abstract: An optical connector includes a plug and an adaptor to which the plug is to be connected. The adaptor is formed with a plug body fitting portion and a holder fitting portion. The plug has a plug body to which a optical fiber cable is fixed. A floating holder is arranged in the plug body to be movable in any direction with respect to the plug body. An end of the optical fiber of the cable is attached to a ferrule which is supported by the holder. When the plug is connected to the adaptor, the plug body is fitted to the plug body fitting portion and the holder to the holder fitting portion. At this time, the plug body is locked to the plug body fitting portion by a lock mechanism, and the holder is locked to the holder fitting portion by engaging projections on the holder and engaging holes which are formed in the holder fitting portion and engaged with the projections.
