Abstract: A unit is connected to both devices to be controlled and the other unit. The unit includes a control unit connected to the devices to be controlled, and a shared memory to be capable of storing therein information. The control unit allocates control data related to the devices to be controlled to the shared memory of its own unit and the shared memory of the other unit so as to be stored respectively in the shared memories.

Abstract: A movement mechanism includes: a guide member; an installation base that is movably provided on the guide member; and a removable cover base that is removably disposed, next to the installation base, on the guide member.

Abstract: A fixing member for fixing a blindfold plate to a support post where a fixing hole is formed, the fixing member includes: a deformation portion that is attached to the blindfold plate, and is inserted in to the fixing hole while being deformed and stays in the fixing hole in a deformed condition when the blindfold plate is fixed to the support post.

Abstract: A first linearly polarized bundle of rays of incident rays is converted by optical modulation with an input video signal into a second linearly polarized bundle of rays orthogonal to the first rays in polarization. The first rays pass through a polarizer before optically modulated. A second linearly polarized bundle of rays originally involved in the incident rays is reflected by the polarizer in a first direction. The second rays obtained by the optical modulation are reflected by the polarizer in a second direction. The second rays reflected in the second direction pass through another polarizer. A first linearly polarized bundle of rays involved in the reflected second rays is reflected by the other polarizer. The reflected first rays is detected by an optical sensor that is positioned outside an optical path of the second rays originally involved in the incident rays and reflected in the first direction.

Abstract: An electronic device is composed of a reflector provided so as to cover a plug of a cabinet (sub-rack) into which a plug-in unit is plugged, and reflecting an electromagnetic wave which leaks from the plug; and a cable support supporting a cable connected to the plug-in unit and taken out of the plug, and forming an absorber which absorbs the electromagnetic wave reflected by the reflector.

Abstract: In a structure in which racks back-to-back with each other are placed on a floor, a bottom of at least one of the racks is pressed against the floor by a connecting bar crossing the bottom. In a structure in which a cover is mounted on a rack, a cover has a first shaft movable in a direction parallel to the first shaft and the cover is mounted on the rack by using the first shaft. In a structure in which a cable rack is mounted on a top surface of a rack, a plurality of engagement screws provided on the cable rack are driven into holes formed on the top surface of the rack so that the cable rack is mounted on the top surface of the rack.

Abstract: A shelf assembly which has realized an easy mounting of a back wiring board to a shelf. The shelf assembly comprises a shelf including a cross beam connecting a pair of side walls on a rear side thereof; and a back-board mounting frame including a pair of side plates each having a vertical guide groove, a first upper connection member and a second upper connection member for connecting the side plates, a first intermediate connection member and a second intermediate connection member for connecting the side plates, and a lower connection member for connecting the side plates. The shelf assembly further comprises a back wiring board inserted into the back-board mounting frame from above along the guide grooves formed in the side plates; and fixing means for fixing the back-board mounting frame to the shelf.

Abstract: A shelf assembly in an electronic switching system in which storability of a cable and coolability of the assembly are enhanced. The shelf assembly comprises an upper stationary rail firmly secured to an upper member of the shelf, an upper slide rail slidably mounted on the upper stationary rail, a lower stationary rail firmly secured to a bottom member of the shelf, and a slide rail slidably mounted on the lower stationary rail. The shelf assembly further comprises a cable box firmly secured to the upper and lower slide rails, the cable box having a plate spreading vertically, an area for receiving the cable being defined in one side surface of the vertical plate; and a drawer unit removably inserted in the cable box along the other side surface of the vertical plate, the drawer unit having a plurality of per-line packages which are withdrawably inserted in the drawer unit, the per-line packages each storing the contents of service per subscriber.
