Abstract: A remote supervisory and controlling system for remotely supervising and controlling loads in time-divisional multiplex transmission of control units and monitor data between a central control and terminal units each connected to the central control unit through a two-wire line. Supervision and control of the overall system can be carried out from a plurality of locations so that failure of a central or host computer will not render the overall system inoperative.

Abstract: An improvement of an information recording medium comprising a disc-shaped resin substrate having an inner-side non-recording zone and an outer-side non-recording zone, a laser-sensitive recording layer, and a flexible resin film (for protection of the recording layer, having protruded and depressed portions on at least the surface facing the recording layer is disclosed. The improvement comprises joining the substrate and the flexible resin to each other on the inner-side and outer-side non-recording zones through fusion by ultrasonic welding or thermal welding in such manner that at least one joining of the flexible resin film to the substrate on the outer-side non-recording zone and the inner-side non-recording zone is effected through a fused portion in the form of a discontinuous ring.

Abstract: A process for producing an information recording medium such as an optical disc comprises the steps: putting a disc-shaped flexible resin film having a hole at its central part upon a surface of the recording layer-side of a disc-shaped resin substrate; placing them on a ultrasonic welding machine between its applying horn and its receiving tool in such a manner that the resin film and the applying horn are opposed to each other, wherein the horn has a ring-shaped protrusion provided with a raised portion; and applying ultrasonic wave to them while pressing the resin film to weld the resin film to the substrate.

Abstract: An information recording medium has such a structure that a disc-shaped substrate is provided with a hole at its central part, an inner-side non-recording zone is provided around the periphery of said hole, an outer-side non-recording zone is provided inside the outer periphery of the substrate, a recording zone is provided between both non-recording zones on the substrate, and a flexible disc-shaped resin film having a hole at its central part is joined to each of the non-recording zones on the substrate in such a state that the resin film is substantially not in contact with the recording zone on the substrate to form a gas layer over the recording zone. A process for producing the recording the medium is also disclosed.

Abstract: A frame assembly for mounting an electric wiring device to a building panel comprises an exposing frame having a front plate to be disposed on a front face of the panel, and rearwardly extending side plates projecting through an aperture in the panel. The side plates carry projections arranged to underlie an edge of the aperture to retain the exposing frame to the panel. A supporting frame is provided for holding at least one of a plurality of modularized wiring devices. The supporting frame is disposed to the rear of the panel when the supporting frame is coupled to the exposing frame. The supporting frame includes tongues arranged to be positioned to the inside of the projections of the exposing frame to elastically support the projections from being uncoupled from the panel. The modular-dimensioned wiring devices are thereby allowed to be mounted to the panel easily without screws or the like.

Abstract: A remote supervisory and controlling system in which a central control unit generates a dummy transmission signal until receipt of an interruption signal from one of a plurality of input terminal units. In response to the interruption signal, the control limit accesses the input terminal generating the interruption signal, which returns its input data.

Abstract: A magnetic recording medium having a thin magnetic recording metal film formed on one surface of a non-magnetic base is disclosed. A thin cured epoxy resin film comprising an epoxy resin having an epoxy equivalent of from 400 to 3,000 and a curing agent made of an aliphatic amine having two or more amino groups and three or more amino active hydrogen atoms in the molecular chain is formed on either the thin magnetic metal film or the surface of the non-magnetic base opposite the thin magnetic metal film or both. A process for producing such magnetic recording medium is also disclosed.

Abstract: A time division multiplexing load control system having a central controller unit for controlling individual terminal units to connect and disconnect loads connected respectively thereto and manual switch means for directly controlling the loads without reverting to the central controller unit is disclosed. A plurality of terminal units are connected through a shared line to the central controller unit to be controlled thereby so as to turn on/off the loads connected to respective terminal units. Each terminal unit connecting the loads is provided with a load-switching circuit for actuating respective load driving relays incorporated therein to connect and disconnect the loads. The load-switching circuit includes switch means which responds to output data signal from the central controller unit to open and close the load-switching circuit for the ON/OFF drive of the load remote from the central controller unit.

Abstract: A system for controlling an electrical load having a magnetic latching relay operable in response to a change in the direction of current through said relay. A control circuit is provided having a switch with one contact connected to a contact of the relay. A first current path and second current path are supplied to a second contact of the switch. The current paths are enabled when the switch operating member connects the relay to the second contact. One of two current carrying paths are provided between the second contact and a source of electrical voltage. The current paths are enabled in response to the voltage stored on a capacitor connected to the first of said contacts. Depending upon the state of the relay, the proper current path is enabled, permitting a change in state of the relay.

Abstract: Seven symbol lamps are aligned, in addition to a six-digit numeral display for displaying time information, in order to indicate any one of the days of the week printed on a calendar panel. A mode panel is disposed, parallel to the calendar panel, on which labels representative of a month information correction mode, a date information correction mode, a day of the week information correction mode, an hour information correction mode, a minute information correction mode, and other operation modes such as a stop-watch mode are provided at positions corresponding to the seven symbol lamps. The symbol lamps are continuously enabled when they indicate the days of the week information printed on the calendar panel, and the symbol lamps are controlled to flicker when they indicate any one of the operation modes represented by the mode panel.

Abstract: A CMOS-LSI including a time information keeping circuit and a display driver circuit is mounted on a flexible film substrate. An upper plastic housing and a bottom plastic housing are provided for tightly supporting the flexible film substrate through screws. That is, the flexible film substrate is sandwiched between the two plastic housings at the periphery thereof, thereby minimizing the flexibility of the flexible film substrate.
