Abstract: A chimney lattice is arranged in a reactor pressure vessel. Thermocouple extension wire pulling conduits inserting a temperature detection thermocouple and a cable connected to the thermocouple are mounted to the upper end of the chimney lattice. By mounting the thermocouple extension wire pulling conduit on the upper end of the chimney lattice, the thermocouple extension wire pulling conduit does not become an obstacle when the fuel assembly is taken out from the chimney. Because the thermocouple extension wire pulling conduit is installed at the upper end of the chimney, the replacement of the thermocouple damaged is easy.

Abstract: Using a network in which one master station modem 105 and multiple slave station modem 106, 107, 108 are physically connected by rudder connection or bus connection with a telecommunication line 121, the measurement result of the S/N ratio between the master station and slave stations is once collected in the master station at the initialization stage, pairs of the modulation method, by which all modems can demodulate at high probability, and transmission voltage are calculated based on this data, and the calculation is transmitted to all slave stations; and at a normal transmission stage, information regarding the coordination and control of the network is transmitted in accordance with this setting. Thus, one-to-multi communication is realized, guaranteeing an access right.

Abstract: An information service system in which information is collected, on a public communication network, from viewers who watch television programs and points are awarded to the viewers in accordance with the collected information, and which is constituted by an interest information generating portion for inputting individual audience result information generated as a result of the viewed television programs into information supply terminals existing on the public communication network to thereby generate individual interest information on the basis of the individual audience result information, an interest information input portion for receiving the individual interest information generated as a result of the viewed television programs from the information supply terminals, a file managing portion for managing an individual interest information file, and a point awarding portion for awarding points to the viewers in according to supply of the individual audience result information, and so on, from the viewers.

Abstract: A pointer remotely points a display screen of a large screen display device. The display screen is picked up by a monitor camera. An image processing unit extracts a feature of the pointer used for pointing based on the resulting image signal to identify the position of the pointing point and the pointer based on the feature. A computer generates information on an object to be displayed at a position pointed by the pointer. The generated information is displayed on a display device (CRT display device or large screen display device) assigned to the pointer. Even when a plurality of pointers are used, the information on the object to be displayed pointed by the pointer is properly displayed.

Abstract: In an apparatus for operating and monitoring a plant, a manipulating device provides the plant with manipulation signals for operating the plant. In response to information supplied from the plant and a manipulating signal of the manipulating device, a first display data producing device produces first display data needed for the operation of the plant changing every moment. On the basis of data supplied from the first display data producing device, a first display device displays information relating to the operation of the plant. In response to information supplied from the plant and a manipulating signal of the manipulating device, a second display data producing device produces data needed for monitoring the plant. On the basis of data supplied from the second display data producing device, a second display device displays information relating to the monitoring of the plant on a larger display screen than that of the first display device.

Abstract: Disclosed is an information processing system having a neural processing unit, an expert system for executing an inference using a rule, and an information selection unit. The neural processing unit and the expert system being arranged in parallel to each other. The information selection unit selects and outputs necessary information from the information outputted from the neural processing unit and the expert system. Since necessary information is selected and outputted from the information obtained from the neural processing unit and the expert system as a result of processing executed by the neural processing unit and the expert system in the parallelly different points of view, the certainty of the information to be selected is improved.

Abstract: Each character string information obtained based on each information inputted by the CRT touch input device and the speech input device respectively is integrated by the input control unit and the memory. The input information analyzing unit analyses the integrated character string information. The output information generating unit generates presentation information corresponding to the demand information obtained by the analysis and outputs this presentation information to the display device. Since the input information from each input device is converted into character string information and it is integrated together and is then analyzed, input information is not restricted by each input device and each input device can be used in a free combination when information is inputted.
