摘要:
A display apparatus of the invention which detects an obstacle put on a display unit, and modifies a place or manner of a display to be performed, comprising the display unit having a display surface; a detecting unit for detecting a display-obstructed area on the display surface where a display-obstructing factor is present; a shifting unit for shifting the area of displayed contents to a displayable area other than the display-obstructed area, when the display-obstructed area is detected; and a display control unit for displaying the displayed contents shifted by the shifting unit in the area other than the display-obstructed area.

A data retrieval system with a keyboard for entering data retrieval conditions. The system includes a first memory for storing subject data to be searched, a second memory for storing data required for searching the subject data, a comparator unit capable of determining whether or not the selected data is greater than, less than or equal to a preset data, and third memory for storing retrieval conditions. The contents of the first, second and third memories is placed into the comparator unit in synchronism with each other.

A data transfer method transfers data to an information-side driver for driving a display apparatus. Wherein, driver circuits each comprise chip address/video data discrimination circuit and a unit driver are mounted around the display apparatus. A unique chip address is set for each of the unit drivers by a hardware pattern. Data exchange with the driver circuits is performed so that chip address information and video data information are time-divisionally transferred to the target unit driver using a chip address/video data common bus line and a chip address/video data discrimination control signal.
摘要:
Display drive of a ferroelectric liquid crystal (FLC) display device is controlled in accordance with temperature and the number of lines to be displayed and updated. An interlace or non-interlace mode for driving the display device is selected on the basis of the number of scanning lines to be updated and/or the temperature. A table is provided for changing the interlace mode on the basis of various conditions.

An information readout apparatus reduces an effective wait time and shortens access time when information recorded on a magnetic disc is read out by effectively utilizing a wait time of a disc rotation. When a sector on the magnetic disc on which a magnetic head is currently positioned is between a start address and an end address, information behind the current sector is buffered and the sequence of the buffered information is rearranged as required and read out so that overlapped readout of the previously read information from the magnetic disc is prevented to shorten the access time. The current sector address is compared with the start address and the end address to process the information.
摘要:
An information processing system processes identification of a track address and a sector address, control of timing, control of reading and writing of data and error checking with reduced intervention of a CPU to a magnetic disc unit so that the throughput of the CPU is increased and performance for data processing is improved. A predetermined number of sectors are processed in sequence, and a greater number of sectors than the number of sectors in one track can be processed by hardware implementation. This system can also control magnetic disc units having different formats.

摘要:
There is a composite image filing system in which optical discs and microfilms are organically combined and integrally managed. This system comprises optical discs and microfilms in which image files are recorded and a work station to register, search, and process the image files. The work station has a memory to store search information of a format integrated between the optical disc and the microfilm. The search information which specifies the image files includes information indicative of the kind of medium (microfilm and optical disc), information to specify the medium number of the optical disc and the physical address in the optical disc in the case of a optical disc file or to specify the cartridge number and frame number in the case of a microfilm file, and the file name. The work station manages the image files by the search information and controls the optical disc so as to back up the search information corresponding to the image files recorded in the optical discs. Since the search information of the image files is stored into a backup dedicated memory such as optical disc or floppy disc nearest to the operation unit, the security of the search information is assured and the search information can be easily managed and reconstructed from the backup dedicated memory.
摘要:
A preserving performance of a display state of a display having a ferroelectric liquid crystal (FLC) as a display device is effectively used, thereby realizing a long life of the display. For this purpose, access monitor device is provided. The access of a video memory by display data supply device is monitored. When there is no access for a predetermined time or more, that is, when there is no change in the present display content, display drive control device controls display driving device so as to stop the driving of an FLC panel.
