IPC: H04N17/02
Filed: 1988-12-02
Abstract: PURPOSE:To evaluate the reproduction of a TV signal by using a composite signal or Y, C component signal having a color difference signal corresponding to a coordinate on the screen as a test pattern. CONSTITUTION:The R-Y and B-Y orthogonal axes are determined by selecting the center of the screen as the origin. A color difference signal is decided as specified on each coordinate (x, y). A color difference signal is subject to orthogonal biphase modulation and a decoded video signal or Y, C component signals are used as test pattern. A luminance signal is made constant. Colors A, B before modulation are placed and shown in figure. The reproduced position of the colors A, B is moved depending on the difference from the demodulation angle of the receiver. The reproduced position of the color is moved respectively depending on the difference (c) from hue or the difference (d) from the blanking level of the color difference signal. Since the color difference signal is determined corresponding to the coordinate on the screen, the color reproduction is easily and simply evaluated visually.

Title: Cellulose ester solution and production of molding
Inventor: TAKEMOTO HIROYUKI
IPC: C08L1/00
Filed: 1994-11-16
Abstract: PURPOSE: To make it possible to use a halogen-free solvent as the poor solvent, to heighten the efficiency of solvent removal and to obtain a molding at good efficiency by using a cellulose ester solution containing a cellulose ester and a cyclic diether as a good solvent therefor. CONSTITUTION: The average degree of substitution of the cellulose ester is 1-3, and the average degree of polymerization is 200-800. A desirable example of the ester is an aliphatic organic acid ester especially cellulose acetate. The degree of acetylation of this ester is 43-62%. Desirable examples of the cyclic diethers include four-membered to seven-membered cyclic compounds such as 1,3-dioxolane and 1,4-dioxane. The boiling point of the cyclic diether is 110 deg.C or below desirably below 100 deg.C because the solvent can be removed at good efficiency and the efficiency of production of a molding can be heightened. As the poor solvent, a halogen-free solvent having a boiling point of 80 deg.C or below (e.g. an alcohol, a ketone or an ester) is used. The ratio of the good solvent to the poor solvent is 30/70 to 90/10 by weight.

Title: Bump for wiring board and its formation method
Inventor: OGASAWARA SHUICHI
IPC: H05K1/00
Filed: 1991-10-29
Abstract: PURPOSE:To provide a very small bump that has good adhesion with a substrate and a method of forming it. CONSTITUTION:After forming a metal layer on one side or a part of an insulation layer, an insulation resist layer is formed on the opposite side of the insulation layer to the side on which the insulation resist layer. After patterning, the insulation layer is dissolved to form holes so that the opening area of the insulation layer that makes contact with the metal layer is of the same order of the opening area of the insulation resist layer. By electroplating with exposed metal surface as a negative electrode or by electroless plating, the holes are filled in. Thus bumps of truncated cone shape are formed. Each bump consists of a truncated cone and a column. The area of the top of the column is nearly the same as the area of the top of the trancated cone. The top of the trancated cone is joined to the metal layer. The top of the column is a little higher than the surface of the insulation resist layer. Then are very small and have good adhesion to the substrate. Such bumps have been difficult to form before. Electronic components of higher performance as FPC, TAB, etc., can be provided with higher reliability.
