IPC: G02F1/133
Filed: 1991-06-14
Abstract: PURPOSE:To uniformize a display picture by preventing the lower part of the screen from becoming whitish in an active matrix liquid crystal display. CONSTITUTION:A fourth gate line is selected in the stage (a). It is regarded that applied voltage to a pixel in the line is inverted positive. Although a first gate line is selected in the stage (b), it is regarded that the polarity of applied voltage remains positive equal to the former frame. Thereafter, in the stages (c) to (f), a second to the fourth gate lines are selected, and voltage applied to the pixel is inverted successively in proportion to that the first gate line is selected succeedingly. In the stage (g), voltage to the pixel on the second gate line is fixed, and voltage on other gate line is inverted successively. In such a manner, the gate line fixed to voltage polarity of the former frame is moved successively.

Title: Method and apparatus for fixation of semiconductor wafer to backplate
Inventor: SATO TSUTOMU
IPC: H01L21/304
Filed: 1989-06-30
Abstract: PURPOSE:To fix semiconductor wafers so as to be brought into contact in an accurate posture by a method wherein the semiconductor wafers where an impurity non-diffusion layer is formed in the central part and impurity diffusion layers are formed on both faces are arranged in parallel at the same intervals as backplates and are lowered onto the backplates and peripheraledge lower parts of the semiconductor wafers are pressurecontacted and fixed to the backplates by an own weight of the semiconductor wafers. CONSTITUTION:The surface of backplates P which have been arranged in a row and regulated is coated with an adhesive C; semiconductor wafers W are lowered onto the backplates P; the surface of the backplates P is brought into contact with the peripheral-edge lower part of the semiconductor wafers W via the adhesive C; the wafers are pressure-contacted and fixed to the backplates P by an own weight of the semiconductor wafers W. The semiconductor wafers W are brought into contact and fixed in an accurate posture in such a way that the backplates P are not moved, tilted and upset, dislocated or the like. As a result, when a fixation process has been finished, a shortage of a fixation strength and an error in a dimensional accuracy are not caused by a movement, a tilt and an upset, a dislocation or the like. Since the semiconductor wafers W are arranged on the backplates P, it is possible to prevent the adhesive C from flowing down to the side of the backplates P and the semiconductor wafers W from being contaminated even when the adhesive C flows out by a cause of its excess or the like.

Filed: 1979-12-26
Abstract: PURPOSE: To avoid large area for each element, by connecting the part between the output terminal of the 2nd inverter and the input terminal of the 1st inverter via a gate in which at the on period of the output gate it is off and it shows usually high resistance.  
     CONSTITUTION: An MOS transistor Q 3  inserted in the feedback path FB between the output terminal N 2  of an inverter INV 2  to the input terminal N 1  of an inverter INV 1 , is made for gate control with a clock ϕ 2 , which is H when the input strobe signal STi is H (the period where the transistor Q 1  is on), and it is L when other cases, especially when the output strobe signal ST o  is H (the period when the transistor Q 2  is on). THus, the MOS transistor Q 3  operated as a high resistance is on/off. Since the feedback path FB is interrupted, the potential at point N 2  is not fed back to the point N 1 . Thus, since the potential at point N 1  is not changed for the data stored, the processing to lower the potential at point N 2 , that is, the increase in the area of transistor Q 2  is not required.

Title: Control method for winding tension of sheetform object
Inventor: HASEGAWA KATSUMI
IPC: B65H23/195
Filed: 1982-09-30
Abstract: PURPOSE:To perform reliable control of total winding tension through a simple system, by a method wherein, out of a plurality og sheetform objects cut in the direction of width, the winding tension of a typical sheet is detected to control all wind-up rolls to the number of revolutions by which the result is approached to a desired value. CONSTITUTION:The number of revolutions of a typical wind-up roll 3a is detected, and control is effected so that the number of revolutions of another wind- up roll 3 coincides with the detected number of revolutions, whereby the winding size of the wind-up roll 3 is naturally controlled so that it always becomes about equal to that of the typical wind-up roll 3a during winding even if there is a difference in thickness between films 1 to be wound. Said control of the winding size causes controlling of a difference in peripheral velocity between each wind-up roll 3 and a sheet feed roller 2 so that the difference becomes about equal to that between the typical wind-up roll 3a and the sheet feed roller 2, whereby the winding tension of each film 1 approaches that of the typical film 1. The typical film 1 is controlled so that its winding tension approaches the desired value of winding tension, whereby control of winding tension to the desired value is made on all wind-up rolls.

Abstract: PURPOSE:To produce a homogeneous and high-purity metal continuously by reducing a metal halide on the surfaces of metal particles in a suspended state by a reducing agent metal to fix and grow the metal in a reaction vessel in which the temp. below the m.p. of the metal and an adequate pressure are maintained. CONSTITUTION:The metal particles of Ti, etc., for forming nuclei as reaction nuclei are charged from a hopper 11 into the reaction vessel 10. On the other hand, the metal halide such as TiCl4 is heated to evaporate in an evaporator 3 and is supplied to the reaction vessel 10 from the lower part thereof. The reducing agent metal such as Mg is simultaneously evaporated in an evaporator 7 and is supplied into the reaction vessel 10. These two vapors are blown up from below the above-mentioned metal particle groups and are suspended to form a suspension bed. The temp. in the reaction vessel 10 is kept below the m.p. of the formed metal and the pressure therein is maintained below the vapor pressure of the reducing agent metal and metal halide at said temp. The reduction reaction of the metal halide is thereby progressed on the surfaces of the metal particles as the reaction nuclei to fix and grow the formed metal such as Ti. The metal particles fixed with this formed metal are continuously withdrawn from an overflow pipe 12.
