Title: Liquid crystal display device
Inventor: YAMADA KENICHIRO
IPC: G02F1/1368
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To suppress the alignment abnormality which arises in the overlap portions to pixel electrodes and to suppress the protrusion of an alignment abnormality region to a pixel display area by forming the inclined parts on the source electrode side of auxiliary capacitance electrodes to the width larger than the width in the inclined parts on such a pixel electrode side. SOLUTION: The inclined parts on the source wiring 2 side of the auxiliary capacitance electrodes 5 formed via an insulating film 12 on the lower layer of the pixel electrodes 4 are formed so as not to be made extremely larger than those on the pixel electrode 4 side. The control of the direction of electric fields is made possible and the pretilt angle of the overlap portions of the auxiliary capacitance electrodes 5 and the pixel electrodes 4 is made larger than within the display area by largely forming the inclined parts on the source wiring 2 side, by which the alignment abnormality arising in the overlap portions of the auxiliary capacitance electrodes 5 and the pixel electrodes 4 is suppressed and the protrusion of the alignment abnormality region to the display area part may be suppressed.  Then, display reliability may be maintained even if the degradation in the pretilt angle in the display area occurs.

Abstract: PROBLEM TO BE SOLVED: To prevent a gate electrode from peeling off due to stress for improved mechanical strength, by forming a side etching part at an opening part comprising a multi-layer structure of SiO2 and SiN layer, for incorporation of the gate electrode. SOLUTION: With a wet processing with buffered hydrofluoric acid, only an SiO2 layer 7 is selectively etched in horizontal direction to form a side etching part 14. Then by a CVD method wherein particle's sticking factor is very small wile excellent in creeping characteristics, a film-formation for a gate electrode is performed, so that Wsi and W may infiltrate inside the side etching part 14, thereby filling up an opening part. Further, a gate electrode 10 is shaped by reactive dry etching. With this method, the gate electrode 10 infiltrates in the side etching part 14, so peeling-off caused by stress is prevented, thus degradation in element characteristics is avoided.

Title: Detecting method for uneven rotation of polygon mirror

IPC: G01M11/00
Filed: 1988-01-18
Abstract: PURPOSE:To detect an uneven rotation without being influenced by the output fluctuation of a laser oscillator and the reflection factor of the mirror surface by allowing the positions of a start pulse and a stop pulse to coincide with the center position of a photodetector output. CONSTITUTION:A laser light beam is made incident from a laser oscillator 3 toward a polygon mirror 2 for rotating around an axis 1. A reflected light beam l scans a prescribed angle range at every mirror surface, and made incident successively on a pair of photodetectors 4a, 4b. Outputs of the photodetectors 4a, 4b pass through amplifiers 5a, 5b and inputted to comparators 6a, 6b and converted to square waves Ga, Gb which rise and fall in a prescribed threshold level of the photodetector output. The first circuit of a counter 7 counts the time extending from the leading edge of the square wave Ga to the trailing edge of the square wave Gb, and the second circuit counts the time extending from the trailing edge of Ga to the leading edge of Gb. When outputs of both the circuits are averaged by an operation processor 8, it seems virtually to be a fact that the time between the center positions (peak positions) of outputs of the photodetectors 4a, 4b is counted.

Abstract: PURPOSE:To perform venting in dies surely by injecting molten metal in the state that the spool valve of a gas exhaust passage is held open, and, upon ending of exhausting of the gas in the cavity, moving the valve onto the axial line with the melt to be injected having entered the cavity thereby shutting off the gas exhaust passage. CONSTITUTION:There is a spool valve 14 at the end part of the venting groove 10 led from the cavity 7 at the releasing plane part of dies 3, 4. This valve 14 moves in its axial line direction. Here, if the valve 14 is opened and molten metal is injected into the cavity 7 through a pouring hole 8, the gas in the cavity 7 is exhausted to the outside of the dies 3, 4 through a vent way 9, a by-pass 15 and a gas exhaust passage 12. Further, when the injection progresses, the molten metal ascends in the venting groove 10, and collides against the under surface of the valve 14, thereby lifting the valve in its axial line direction. At the same time, part of the molten metal enters the by-pass 15, and in due course of time, the ascending of the valve 14 is stopped by a stopper 18, by which the part between the by-pass 15 and the gas exhaust passage 12 is closed and the molten metal is dammed up. During this time, the gas in the by-pass 15 is exhausted as well.
