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: Each of right and left attaching units of a front loader of a working vehicle has a pair of side plates extending vertically, and a connecting member interconnecting the side plates in positions intermediate in a fore and aft direction, As a result, each of the right and left attaching units has an H-shaped cross section.

Abstract: A synchronism detection and demodulating circuit includes: a circuit for frequency dividing the regenerative clock in an irregular manner, a circuit for reading out the input data in a special manner based on the clock and producing data that provides information about the readout data, and a circuit for deleting unnecessary data from the readout data based on the data providing the information.

Abstract: A digital VTR which is able to record a band-compressed signal having a bit-rate of 17 to 60 Mbps of a program while creating a low-bit-rate signal (1.5 to 5 Mbps) having the same program content as well as utilizing the low-bit-rate signal as a signal for the special playback. Variable speed playback data for a certain speed, which is recorded in the limited recording areas for variable-speed playback mode, is adapted to be used for playback at another speed in the variable-speed playback mode. The data structure of variable-speed playback data is adapted to change depending on the image areas on the image frame. Either of these embodiments or the combination of them, improves the quality of a reproduced picture during variable-speed playback mode in which a less amount of data is available than that of data read out at the time of a normal playback mode.

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.

Abstract: An alarm system in a plant for outputting a plurality of alarms with respect to devices constituting the plant and monitor information with respect to the devices. In the system, there is provided a unit for storing a table for correspondingly relating a plurality of alarm items to suppression reason items indicating that the display of the alarms can be suppressed. A generated alarm item and a generated event are specified by receiving the plurality of alarms and monitor information. A decision is made by reference to the table as to whether the generated alarm suppression reason item exists in the monitor information, the kind of generated alarm, and the generated event for each generated alarm item. An instruction is given to a display unit to suppress the display of alarms in which a decision is made that the suppression reason item exists.
