Abstract: A display apparatus includes circuitry to display a display screen based on a video signal input from an information terminal, acquire a change in an image indicating a position on the display screen based on the video signal, and receive an operation with respect to the display screen, based on the change in the image.

Abstract: A network control system includes a network controller, and an information processor connected to the network controller via a first communication path complying with a first standard. The network controller is connected to an external device via an another communication path complying with the first standard. In response to receiving a packet from a transmission source that is registered in advance, the network controller transfers the packet to the information processor via the first communication path. When the packet transferred from the network controller is a special packet that is registered in advance, the information processor notifies the network controller of a content of an instruction indicated by the special packet via a second communication path. The network controller generates a special packet including the content of the instruction notified from the information processor, and transmits the generated special packet to the external device via the another communication path.

Abstract: An apparatus communicable with an external apparatus using serial communication includes a communication interface connectable with the external apparatus, a first controller connectable with the communication interface, a second controller connectable with the communication interface, and a switching device to connect the communication interface with one of the first controller and the second controller depending on an operation mode of the apparatus. When a transition request to an energy-saving mode is detected while the first controller is connected with the communication interface, and the communication interface is connected with the external apparatus, the switching device switches a connection partner of the communication interface from the first controller to the second controller.

Abstract: A network management system which can easily rebuild the system even when a switch in the configuration of cars occurs. A monitor apparatus including monitor cameras (1-1˜1-4, . . . ) and recording devices (1-5, . . . ) in each car (21a, 21b, . . . ) is networked. Each intra-car network is constructed as a LAN, a router (1-10 (RT1), . . . ) is connected to the LAN in each car, and an inter-car network is constructed as a WAN. The same apparatus in each car and apparatuses provided at the same positions are connected to a port of the same port number and the same LAN address is allocated to such an apparatus. As for an access from a WAN side, which apparatus is accessed is defined only by a difference in port number. Network information of the car switched car can be set merely by switching the setting of the WAN address of the router, . . . .

Abstract: A computer-aided design apparatus improves operability in CAD and includes a view function which automatically enlarges a view frame or automatically modifies the display scale factor if a drawing element that exceeds the view frame is input. The computer-aided design apparatus performs design work by setting a plurality of views of different origins and coordinate systems on a screen.

Abstract: A plurality of character train primitives existing on a CAD picture plane can be simultaneously inputted and edited on a document picture plane and character trains are inputted and edited. A character train converting module converts the character train primitives on the CAD picture plane into the character train on the document picture plane and displays. On the contrary, the character train converting module converts the character train on the document picture plane into the character train primitives on the CAD picture plane and displays. While the character train converted and displayed from the character train primitives on the CAD picture plane is being edited on the document picture plane, a CAD reflection processing module reflects the edition contents on the document picture plane to the character train primitives on the CAD picture plane.

Abstract: A switch-equipped connector device, comprises: a case having an opening; a cover to be removably mounted on the case so as to cover the opening; a first connection terminal on the side of load and a second connection terminal on the side of a power supply, a connection portion between which is exposed from the opening, and which are held in the case; a short-circuiting terminal attached to the cover; a switch connector located in said opening, the switch connector to be electrically connected to the short-circuiting terminal in the opening, the short-circuiting terminal being disconnected from said switch connector when the cover is removed from the case; and a switching device connected to the second connection terminal through the power supply, the switching device interrupting power supply to the second connection terminal when the cover is removed from the case.

Abstract: A hybrid vehicle has a clutch between the engine and the rotational electrodynamic unit. A driving energy transmission mechanism is provided between the clutch and the rotational electrodynamic unit for transmitting driving energy to an appliance such as an alternator. When driving the engine, the clutch is closed by a clutch controlling unit, and the engine makes the rotational electrodynamic unit function as a generator to operate the appliances. When the engine is stopped, the clutch is opened by the clutch controlling means, and the rotational electrodynamic unit is caused to operate as a motor to operate the appliances. In the system where the appliances are driven by the engine, the appliances are kept being operated even after the engine stops. This structure is applicable to both a series hybrid vehicle and a parallel hybrid vehicle.

Abstract: A drive apparatus for a hybrid vehicle equipped with an engine and a motor, heats the engine or a catalytic converter using the regenerated electricity of the motor. As the temperature of the engine or the catalyst thus rises, air polluting components in an exhaust gas discharged via the motor or the catalyst converter are reduced. Typical air polluting components are NC, NOx and CO.

Abstract: A wire cutting type electrical discharge machining system for removing metal by utilizing of an electrical discharge energy between an electrically conductive workpiece and a wire electrode which is continuously fed lengthwise relative to the workpiece, including a frame, a wire guide conduit, and a flexible tube inserted in the wire guide conduit. The wire guide conduit is disposed fixedly with respect to the frame, so that the wire electrode is passed through the conduit. The flexible tube is axially slidably moved in the wire guide conduit in a telescopic fashion such that an outer end of the flexible tube is movable outwardly away from a corresponding end of the wire guide conduit, to an access position at which one end of the wire electrode may be easily inserted into the flexible tube through the outer end thereof and guided by the flexible tube into the wire guide conduit.
