Title: Picture binarizing method
Inventor: FUJIKURA SHUICHI
IPC: G06T5/00
Filed: 1990-07-30
Abstract: PURPOSE:To exactly prevent the occurrence of moire at dots by selecting and outputting a prescribed density in the case of matching between the form of edges of a prescribed pattern but selecting and outputting the binarization result in the other case. CONSTITUTION:An edge detecting part 14 detects edges in accordance with the density difference between a noticed picture element and its peripheral picture elements (for example, eight peripheral picture elements) based on an output signal S10 of an input part 10 and outputs detection signals S141 to S148 to a pattern matching part 15. This part 15 collates the form of edges with prescribed patterns by detection signals S141 to S148 and performs the pattern matching processing to discriminate whether the form of edges is matched to a prescribed pattern or not, and the processing result is given to a selector 13 as a control signal S15. The selector 13 selects a black signal S12 from a density setting part 12 when it is matched to the pattern; but otherwise, a binarized signal S11 of the noticed picture element outputted from a binarizing part 11 is selected.

Title: Liquid crystal display device
Inventor: ICHIOKA SUSUMU
IPC: G02F1/133
Filed: 1983-10-28
Abstract: PURPOSE:To minimize the difference in visibility in each part with respect to the observer's viewing point by subjecting a base plate to nonlinear orientation slitting to provide a distribution which makes twist angle increasingly smaller or larger toward the upper part of a display image plane. CONSTITUTION:One or both of the base plates of a liquid crystal display device 1 sandwiching a nematic liquid crystal between two sheets of the base plates having electrodes are subjected to nonlinear orientation slitting to have the distribution which makes the twist angle increasingly smaller or larger toward the upper part of the display image screen thereby increasing the display contrast ratio on the low visual angle side toward the upper part of the display image screen or decreasing said ratio by the main visually recognizing direction 3. The increase or decrease in the twist angle is resulted in the vertical direction of the image screen by such slitting but at the same time the central direction of the twist angle, i.e., the preferential visual angle direction shifts to the center of the image screen in the lateral direction. The display device has consequently the tendency that the lateral part of the display image screen is preferentially visually recognized in the visual point direction of the observer, that is, at the front-downward center, by which all the peripheral parts of the image screen are made satisfactorily visible for the observer's viewing point.

Title: Picture freezing device
Inventor: MATSUMOTO SEIJI
IPC: A61B1/04
Filed: 1990-08-01
Abstract: PURPOSE:To acquire a sharp picture by detecting the presence of movement of an object with a movement detection means so as to set an operating timing of a switch means, controlling freezing and detecting an image pickup timing of a frozen picture automatically. CONSTITUTION:When a freeze operating means 8 is operated, R, G picture data are fetched from a pre-stage of a color encoder 15 to a differential arithmetic circuit 23. Then the R, G signals are given to the differential arithmetic circuit 23, in which a signal R-G is generated and it is compared with a prescribed reference value at a comparator circuit 24 to extract only a negative component and it is integrated. Then the comparison is implemented every time the R and G picture data are outputted from a CCD 5 and before it is discriminated that no movement exists, the picture is not frozen via an analog switch 20. Thus, in the case of picking up the frozen picture, a sharp frozen picture is surely acquired by one operation without color slurring.

Abstract: PURPOSE:To avoid the contamination of a wafer by a residual gaseous component. CONSTITUTION:A thin film having the same compsn. as a target 5 is formed on a wafer 4 in a vacuum vessel 1, a thin film of a compd. is further formed on the wafer 4 by reactive sputtering and then the concn. of a reactive gas remaining in the vessel 1 is measured with an analysis tube 9.

Abstract: PURPOSE:To satisfactory sustain the durability of a frictionally engaging device, by increasing the line pressure of a hydraulic control device only during an engine exhaust brake device being operated so that fuel consumption and gear shift feeling during normal travel are sustained. CONSTITUTION:A basic hydraulic pressure generated by an oil pump 12 is regulated by a primary regulator valve 14 to generate a line pressure in accordance with the opening degree of a throttle valve. Accordingly, when exhaust brake is effected, a switch 26 is turned on, and therefore, a solenoid valve 38 open a drain oil passage 38A to discharge hydraulic pressure in a throttle valve pressure oil passage 50(52). Therefore, throttle valve pressure applied to lands 18B, 18C in a throttle valve 18 is released to adjust a throttle pressure Pth and therefore the line pressure to be high. Accordingly, hydraulic pressure acting upon a frictional engaging device 34 becomes higher so that the engagement of the latter is completed in a short time. As a result it is possible to shorten a period during which frictionally engaging elements slides on each other, and to enhance the durability thereof, correspondingly.
