  • 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.

  • Patent number: 5742358
    Abstract: A projection type displaying apparatus with a movable built-in screen has an image display, an image projector and a position detector for detecting a position where the built-in screen is installed. When the position detector determines that the built-in screen is in an image projection pass, the focus of the image projector is adjusted on the built-in screen and the image projector projects the image onto the built-in screen. When the position detector determines that the built-in screen is out of the image projection pass, the focus of the image projector is adjusted on an external screen and the image projector automatically projects the image onto the external screen.

  • Patent number: 5740518
    Abstract: An FM broadcasting signal carrying multiplex character data transmitted from a radio broadcasting station is automatically preset in an FM receiving apparatus. An FM broadcasting signal is received, and a frequency information of the received FM broadcasting signal is temporarily memorized in a memory. It is judged whether a PLL lock signal is produced by a clock signal reproducing circuit during a demodulation process of the FM broadcasting signal whose frequency information is memorized in the memory. When it is determined that the PLL lock signal is produced by the clock signal reproducing circuit, it is determined that the FM broadcasting signal carries multiplex character data, and the frequency information of said FM broadcasting signal is preset to the FM receiving apparatus.

  • Patent number: 5739823
    Abstract: A graph display device which includes an expression input section for inputting functional expression data, an expression color setting for setting a display color for the functional expression data input by the expression input section, and an expression display section for displaying the input functional expression data in the display color set by the expression color setting section. A graph producing section produces a graph for the functional expression data input by the expression input section based on the input functional expression data, and a graph display section display the graph produced by the graph producing section in the same display color as that set for the functional expression data.

  • Patent number: 5736436
    Abstract: A gate electrode, a semiconductor thin film, a channel protecting film and a photoresist are accumulated on the overall surface of a transparent substrate on which a gate electrode and a gate line are formed. Ultraviolet rays are irradiated through the substrate so that the photoresist and the channel protecting film are self-aligned with respect to the gate electrode and the gate line. A mask is formed on the channel protecting film so as to extend in a direction perpendicular to the channel protecting film. The channel protecting film and the semiconductor thin film are etched using the mask. As a result, the semiconductor thin film and the channel protecting film are patterned without positional deviation so as to have the same width W. Therefore, it is possible to reduce the thin film transistor forming region and the number of steps of the manufacturing process.
