Title: Liquid crystal display device
Inventor: HORI YOICHI
IPC: G09G3/36
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which suppresses display defects, such as crosstalks and writing deficiency. SOLUTION: A timing controller 12 outputs a start pulse and clock signal and scanning lines are successively selected in a scanning drive circuit section 4. This timing controller 12 outputs the start pulse and the clock signal of an anti-phase, successively shifts shift registers and outputs a gate signal to an analog switch section. The analog switch section writes data in data lines in accordance with the gate signal outputted from the shift register section and the data of a digital/analog converter 13. If the output pulse is bold, the phase of the clock signal of the anti-phase with respect to the clock signal is shifted forward and the pulse width is fine, by which the crosstalks are prevented. When the output pulse is fine, the clock signal is shifted backward and the pulse width is increased, by which the display defect by the writing inconsistency is suppressed.

The ingot is subjected to >=1 times of a temp. decrease to the Ar3 point or below and is then recuperated to the Ac3 point or above during or after the above-mentioned process. The recuperated ingot is then passed through drawing rolls. The steel ingot obtd. in the above-mentioned manner is free from cracks and flaws and can be therefore subjected to direct hot working without reheating prior to the succeeding hot working.

Filed: 1990-06-29
Abstract: PURPOSE:To obtain the inexpensive high-speed video camera by composing signals obtained from first and second scanning mechanisms where objects are mutually and equally projected on one screen. CONSTITUTION:By a solid-state image pickup element 3a, a vertical clock pulse is inputted to a vertical shift register as far as the upper part area of an image pickup surface, that means, as far as scanning lines 1 - 120 and they are scanned at a speed corresponding to the normal scanning time of a field, for example. By a solid-state image pickup element 3b, a horizontal clock pulse is inputted to the vertical shift register at timing corresponding to the scanning line 1 as far as the scanning lines 1 - 120. By inputting the vertical clock pulse to the vertical shift register when the timing corresponding to a scanning line 121 is attained, the lower part area of the image pickup surface, that means, the scanning lines 121 - 240 are scanned at the scanning speed of a standard television. Both signals are adjusted to a proper signal level by extraction, amplifier and processing circuits 4a and 4b and composed by a composition circuit 5 which is used for composing them to be one picture and which includes a recording function. Thus, the inexpensive high-speed video camera is obtained.
