Title: Liquid crystal display device
Inventor: TSUMURA MAKOTO
IPC: G02F1/1343
Filed: 1990-08-08
Abstract: PURPOSE:To prevent regular light-shade stripes from being formed by arranging an area where light is not transmitted in the center of a rectangular area which varies in light transmissivity, dividing the area longitudinally and laterally at constant intervals, and nearly equalizing the divided areas in area. CONSTITUTION:Opening parts 504 and 505 which are nearly equal in area are arranged in one display dots at a distance 503 which is about a half as long as the longitudinal pitch 317 of display dots, and lateral intervals of all opening parts are equal to the lateral pitch 316 of the display dots. the spatial frequency of the display dots is prescribed laterally by the reciprocal of the lateral pitch 316 and longitudinally by the reciprocal of the distance 503 at which the two opening parts 504 and 505 are arranged at equal intervals. Consequently, the spatial frequency of the display dots is prescribed by the reciprocal of the longitudinal pitch 317 and the quantity of transmitted light becomes constant, so that the light-shade stripes are never generated on alternate lines.

Inventor: KAMEDA HIROKAZU
IPC: B32B17/06
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a composite laminate having no open voids though it is porous. SOLUTION: A green laminate equipped with a first sheet layer 2 containing an anorthite type crystallized glass powder and a first powder like an alumina powder and the second sheet layers 3, 4 provided in contact with both surfaces of the first sheet layer 2 and containing a second powder like an alumina powder not sintered at the softening point of the anorthite type crystallized glass being a part of the first powder is prepared to be baked at temp. higher than the softening point of anorthite type crystallized glass. By this baking, anorthite type crystallized glass is melted before the first powder is densified by sintering and diffused or fluidized throughout the second sheet layers 3, 4 so as to fill the gaps of the second powder. By this method, a composite laminate 1 wherein the first sheet layer 2 is porous and the second sheet layers 3, 4 have no open voids is obtained.

Title: Ball sliding machine
Inventor: ISOKAWA NOBUHIRO
IPC: B24B9/14
Filed: 1986-09-06
Abstract: PURPOSE:To improve the machining accuracy of a lens, by turning an arm around a crossing point of a second plane which is in parallel with a first plane containing a lens rotary shaft of a carriage and a grinding wheel rotary shaft and further contains the rolling shaft of the carriage and a third plane which is approximately perpendicular with said first plane thereby lifting/ lowering a mold receiver. CONSTITUTION:When a guide rail 61 is lifted/lowered by a motor, an arm OA having a turning axis which is a cross point of a second plane S2 and a third plane S3 is rotated around said axis OA through a roller 50. At the same time, a mold receiver 20 fixed at the tip of a support 21 is lifted/lowered and the center of curvature OK of a template contacting face 20a of the mold receiver 20 moves on an arc having said axis OA as a center. Normally, the turning range of the arm 30 is within a micro angle, thereby the center of the curvature OK can be considered to move on the first plane S1. Consequently, the contacting point of the template T with said contacting face 20a and the grinding point of a lens come on an approximately same line, resulting in the improvement of grinding accuracy of the lens.

Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To improve the responding speed by reducing the number of switching elements and a stray capacitance due to the number of the elements by differentiating an address input signal, and forming an address transition signal from the differential signal. SOLUTION: An address input signal Ai is input to a differentiator 50 having a capacitor C1 and a ground resistor R1 , and differentiated by a transfer function of the constitution to obtain a pulse signal.

Abstract: PURPOSE: To detect an inter-electrode reactive current or a reactive current between an electrode and an equipment body to precisely control ion generation by providing an external ground part and an external grounding resistor, and entirely gently increasing and decreasing the high voltage imparted to each discharge electrode. CONSTITUTION: A positive side effective static eliminating current I1+ carried form a positive side discharge electrode 1 to the outer part of a static eliminator is reflexed from an external ground part 10 to the electrode 1 through an external grounding resistor 11, a discharge current detecting resistor 8 and the secondary side coil of a positive side transformer 5. The negative side effective static eliminating current I1- carried from the outer part of the static eliminating device to a negative side discharge electrode 2 is refluxed to the part 10 through the resistor 11. While the overall time change of both high voltages V+ , V- imparted to each electrode 1, 2 are made relatively gentle, the voltages V+ , V- are controlled so that either one of the voltages V+ , V- is minutely fluctuated by a minute time.  Thus, the positive and negative side effective static eliminating currents I1+ , I1- and the positive and negative side electrode-cage body reactive currents I2+ , I2- can be detected by a prescribed expression, and ion generation can be precisely controlled.
