Title: Method for driving liquid crystal display device
Inventor: WAKAI YOICHI
IPC: G09G3/36
Filed: 1991-10-09
Abstract: PURPOSE:To saturate a shift in I/V characteristics of a nonlinear element, to equalize write conditions of charges to a liquid crystal layer as to all picture elements on a screen, and to preclude an after-image phenomenon by applying a large voltage right before a selection period while its polarity is inverted plural times. CONSTITUTION:Column electrodes Xm and row electrodes Yn are formed on opposite substrates and a nonlinear element 116 and a liquid crystal layer 115 are arranged in series at each fulcrum. The shift register start signal DY of a Y driver 102 is shifted as a shift locking signal YSCL falls and a selective signal is transferred exactly according to its width. The DY is as wide as four clocks, so the selective signal also has the clock width (four selection periods) of the YSCL4. In this period, a voltage which is larger than that in a normal selection period is applied. Since FR performs one-line inversion driving which causes inversion at each selection period, so an AC inverted signal has the dummy signal of three selection periods before a signal is actually selected and the polarity is changed three times.

Title: Traveling controller of unmanned carriage
Inventor: ISHIDA HIDETOSHI
IPC: G05D1/02
Filed: 1992-09-04
Abstract: PURPOSE:To smoothly travel at a corner part and reduce the cost of a guide member by almost equalizing the radii of the corner parts of the guide member and driving a right and a left driving wheels at a speed ratio nearly equal to a travel distance ratio at the time of the corner part travelling. CONSTITUTION:The travel machine body of the unmanned carriage automatically travels along a reflecting tape 13 for guidance based on the detection of a photosensor 12. If the carriage is deviating from the reflecting tape 13, the right and left driving wheels are driven at a specific speed ratio to correct the direction. This speed ratio is nearly equalized to the travel distance ratio of the right and left driving wheels 4 at a corner part which is equalized in turning radius, so the driving wheels 4 are not driven and switched frequently during the corner part travel and the carriage automatically travel along the reflecting tape 13. Therefore, the corner part travel can be made extremely smooth. Further, the kinds of the reflecting tapes 13 for the corners are limited to one, so the cost is reducible and laying operation is facilitated.
