  • Patent number: 5761340
    Abstract: When data to be copied is enclosed on the screen of an input/display device by a figure image represented by an enclosing figure (a circle with an open part), the data is stored together with the figure image. When the same figure image is drawn in a slightly larger size in an unwritten area, a target copy area is automatically set inside the figure image and the stored data is enlarged and displayed in the target copy area according to the dimension of the set area.

  • Patent number: 5757346
    Abstract: A technique for inspecting a liquid-crystal display module which includes a liquid-crystal panel and a liquid-crystal display driving device, wherein the liquid-crystal display driving device is provided with a selecting section for selectively switching between (i) outputting of various data items stored in a memory section to an inspection device and (ii) outputting of the stored data to a driving section to drive a liquid-crystal panel, on the basis of execution instruction data from the inspection device. The inspection device selectively writes and reads character data into and from a DDRAM, a CGROM, and a CGRAM in the memory section of the liquid-crystal display driving device one after another and inspects the display in sequence.

  • Patent number: 5757448
    Abstract: A pair of substrates both having electrodes are arranged to oppose each other and bonded via a sealing member. A liquid crystal/polymer composite film is formed inside this structure, and color filters of red, green, and blue are formed on one of the two substrates. This liquid crystal/polymer composite film consists of liquid crystal domains and a polymer. The liquid crystal domains are so formed that regions corresponding to the color filters of different colors have an essentially equal optical effect on light components having the respective transmission wavelength bends of these color filters. The polymer is formed by polymerizing a photosetting polymeric material.

  • Patent number: 5757028
    Abstract: A thin film transistor which can reduce production of leakage current between the source and drain electrodes and a fabricating method therefor, are disclosed. In the thin film transistor, an insulating film is formed on at least a portion of each side, corresponding to the region between the source and drain electrodes, of the peripheral side surface of the intrinsic semiconductor film, so that no metal silicide is formed thereon.

  • Patent number: 5758332
    Abstract: An information service providing system using a network comprises a terminal group, an information processing center, and various types of databases. When a portable terminal transmits the category of information service and the retrieval condition data to the information processing center, the center selects the necessary database on the basis of the category of service and searches the databases selected in a chain reaction manner using a retrieval result as the next retrieval condition so as to fulfill the retrieval conditions. Then, the center outputs the retrieval results of the databases to the terminal.

  • Patent number: 5755504
    Abstract: A screen device include a screen unit, onto which an image is projected and an infrared ray transmitting unit provided in the vicinity of the screen unit, for allowing infrared rays to pass therethrough. Since the infrared rays are allowed to pass through the infrared ray transmitting unit, the infrared rays emitted from a remote controller are guided from one side of the screen unit to other side thereof. Therefore, even though an apparatus to be controlled by the remote controller is installed behind the screen unit, the apparatus can be controlled by means of infrared rays emitted from the remote controller.

  • Patent number: 5753937
    Abstract: A color liquid crystal display device includes a front substrate having a surface on which a plurality of pixel electrodes are arranged in the form of a matrix, and two-terminal nonlinear resistor elements are arranged to correspond to the pixel electrodes. An aligning film covers the pixel electrodes and the nonlinear resistor elements. A rear substrate opposes the front substrate and has an inner surface on which counter electrodes are arranged to oppose the pixel electrodes, for forming a plurality of pixels. An aligning film covers the pixel and counter electrodes. A liquid crystal layer is sandwiched between the front and rear substrates and has an initial aligned state in which liquid crystal molecules are aligned in a predetermined direction by the aligning films.

  • Patent number: 5754160
    Abstract: The present invention relates to a liquid crystal display device in which a liquid crystal display panel is divided into a plurality of areas and the number of common lines scanned at once is changed for each of the areas. More specifically, the liquid crystal display panel is divided into a 2.alpha. drive area and a 1.alpha. drive area. Based on a CDB signal, a scanning circuit selects and scans two common lines at once in the 2.alpha. drive area and shifts the selected two lines one by one. The scanning circuit selects and scans one common line in the 1.alpha. drive area and shifts the selected line one by one.

  • Patent number: 5741082
    Abstract: In a tape printer which prints text data including characters/symbols on a tape, there is a fixed distance between a position where a thermal head is provided and a position where a cutter cuts a printed tape portion. For first text data to be printed, a margin is set and then the data is printed on the tape. Thereafter, the next text data is input with a margin being set and printed on the tape. When the printing of the first text data ends, the operation of the printer stops. When the printing is continued after the next data is input with a margin being set, the tape is conveyed by a length equal to the sum of the margins and set for the respective first and second text data and the input next data is printed. When the boundary between the margins arrives at the position of the cutter during the printing of the next text data, the printing of the next text data is interrupted and a tape portion on which the previous text data has been printed is cut by the cutter from the remaining tape.
