Abstract: PURPOSE:To discriminate a specific body, by comparing light and shade distribution states of the flashing of a light emitter having a light emitting axis parallel to the light receiving axis of the optical system of an image sensor and emitting light in an ON/OFF state. CONSTITUTION:For example, a specific body is assumed to be a reflecting body. The light and shade distribution obtained when a light emitter 5 irradiates the visual field of an optical system 2 along the light emitting axis thereof parallel to the light receiving axis of the optical system 2 and that obtained when the light emitter 5 does not irradiate the optical system 2 are received by a sensor (CCD row) 8 and binarized to be detected and compared by a built-in control circuit part 16. The brightness of the light emitter 5 is weak under the sunlight but only the specific body reflects the light emitted from the light emitter 5 and the brightness thereof changes between at the time of light emission and at the time of light non-emission. Therefore, the specific body present at a part located in an unchanged environment can be easily discriminated.

Abstract: PROBLEM TO BE SOLVED: To provide a driving method for liquid crystal display device minimizing the change of the pixel potential of liquid crystal and canceling flicker and the difference of luminance between pixels even if the delay time of the gate bus line of the liquid crystal display device is long. SOLUTION: Gate-off improving potential for making the timing of gate-off of TFT(thin film transistor) constant is applied after application of the gate potential Vgh for turning on TFT and before the application of modulated signal potential composed of two voltage levels for compensating the punch- through potential induced on a pixel electrode and a leakage current between a drain and a source of TFT is made equal and small. By adopting the lower value of the modulated signal potential or the farther low value as the gate-off improving potential, the delay time of TFT gate-off is decreased. A gate driving signal of a horizontal period is issued during the application periods of Vgh and the gate-off improving potential. The application of the gate signal to the next stage is started after the lapse of this horizontal period.

This compound is reacted with a polyisocyanate compound (e.g., tolylene diisocyanate) in the presence of a blowing agent based on water to obtain a synthetic resin foam. Because the active hydrogen compound contains the aminated polyol, a drawback otherwise encountered in water blowing, i.e., the delay of the start-up of reaction can be solved.
