  • Patent number: 6539660
    Abstract: A handgun rest suitable for field use includes a shooting platform on which the shooter rests the butt of the handgun grip and both hands. The platform connects to an adjustable extension member or assembly projecting forward from the platform, angling upwards to provide both the required amount of upward rise and forward extension to come under, and provide the rest for, the forearm or barrel of the handgun. Thus the weight of the handgun is supported fore and aft, including the shooter's wrists and arms. The forward extension is folded when not in use, creating a compact and easily transported package. A leg assembly coupled beneath the platform permits both swiveling and canting. The leg assembly includes a pair of movable legs coupled about an axle which engages a bracket movably mounted under the platform. The bracket engages a pivot about which the bracket may rotate, within constraints, relative to the platform.

  • Patent number: 6058183
    Abstract: An advanced telephone dialler has been described, incorporating a fast retrieval and dial telephone directory. The system simplifies the use of the telephone directory by using a single sliding or rotary key for scanning and selection of the name and number to be dialled and one button for speed dialling of the selected number. The name and telephone number of the selected person are simultaneously displayed on a character display and a normal telephone keypad has been used for entering both letters for the name and digits for the number into telephone directory's memory. A short cut dialling has been also provided by simply using the sequential order number of the person to be dialled from the telephone directory's memory. An option has been provided for checking the incoming calls numbers with the telephone directory of the system and not only displaying the name of the calling person and its number if they have been found in directory.

  • Patent number: 6023257
    Abstract: A driver circuit for driving an active matrix liquid crystal display without producing flicker. The inversion frequency of the voltage applied to the liquid crystal panel of the display is examined, the frequency being intrinsic to the display. The difference between voltages applied to opposite sides of the liquid crystal panel is found from the transmissivity of the liquid crystal material, by making use of an image sensor. The found value is converted into digital form by an analog-to-digital converter and stored in a correcting value storage device. When the active matrix display is in use, the difference signal which is found for each pixel and stored in the storage device is added to an image signal applied to the active matrix display, thus preventing flicker intrinsic to the liquid crystal panel.

  • Patent number: 5956008
    Abstract: A driver circuit for use with an active matrix display. The driver circuit has a shift register circuit of a redundant configuration and consists of a main circuit and a preliminary circuit. When the main circuit becomes defective, the operating circuit is automatically switched from the main circuit to the preliminary circuit without physically cutting the circuitry by a laser beam or the like. The driver circuit is composed of a main shift register circuit and a preliminary shift register circuit connected in parallel with the main shift register circuit. The output from the final stage of flip-flop circuit of the flip-flop circuits forming the main shift register circuit is compared with the output from a monitoring flip-flop circuit connected with the output of the final stage of flip-flop circuit. Thus, the output signals from the flip-flop circuits of the main shift register circuit are switched respectively to the output signals from the flip-flop circuits of the preliminary shift register circuit.

  • Patent number: 5941967
    Abstract: In a multiprocessor system with shared resources, which several processors access via a system bus by presenting bus access requests to an arbitration unit and receiving from the latter access grant signals and in which the busy state of a resource or a conflict of consistency determine the generation of a RETRY signal and compel the processor, which has obtained access to the bus, to execute an access RETRY attempt, consecutive repeated access RETRY attempts of the same processor activate logic of the arbitration unit which temporarily mask, for a varying duration, the access requests of the same processor for the execution of further consecutive RETRY attempts, the varying duration first increasing as a function of the number of further RETRY attempts and then varying in a random manner.

  • Patent number: 5942356
    Abstract: A half tone type phase shift mask as well as a phase shift mask blank for the mask is formed with a thin film light translucent portion made of essentially, nitrogen, metal, and silicon. The containing rate of each element and ratio in the thin film is specified in a certain range to improve film characteristics, such as acid resistance, photo resistance, conductivity, refractive index rate (film thickness), light transmission rate, etching selectivity, etc. of the light translucent portion. The phase shift mask satisfies optical characteristics (i.e., light transmitting rate and phase shift amount) with high precision, as well as reduces defects in the thin film.

  • Patent number: 5920300
    Abstract: It is intended to increase the display speed in an active matrix liquid crystal display device. In displaying a moving picture, different voltages are applied in two steps to each pixel, i.e., each liquid crystal cell. More specifically, after a high voltage is applied first, and then a low voltage is applied at a prescribed timing, so that the rising characteristic of the liquid crystal is improved. In a specific configuration, thin-film transistors are provided on both sides of a pair of electrodes between which the liquid crystal is interposed. A voltage for accelerating the liquid crystal operation is applied from one of the two thin-film transistors, and the same voltage as in the case of displaying a still picture is applied from the other thin-film transistor.

  • Patent number: 5903249
    Abstract: The object of the invention is to design for reduction of the effects of thin-film transistor OFF current and to improve image quality in an active matrix display device in which polysilicon thin-film transistors are used.Plural serially connected thin-film transistors are provided for one pixel electrode, different signals are imposed on the gate terminals of respective thin-film transistors, and a signal is written into the pixel when all the serially connected thin-film transistors are in an on state.Further, since the thin-film transistors are connected in series, the voltage imposed on the source and drain electrodes when they are all in an off state is divided, and consequently the voltage across the source and drain electrodes of the thin-film transistor that drives the pixel is smaller and the OFF current is reduced.
