Title: Method for compensating nonuniformity of display by change in primary color of color monitor
Inventor: ON SEIHATSU
IPC: H04N9/30
Filed: 2000-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for compensating the nonuniformity of display by a change in primary colors of a color monitor by using a virtual primary color method. SOLUTION: The chromaticity coordinates and maximum luminance of the primary colors of respective pixels in the monitor are measured and one set of virtual primary colors are selected from the measured values of all the primary colors. The tristimulus values of the respective virtual primary colors are generated from the respective pixels in the monitor. The characteristics of the virtual primary colors are displayed by the chromaticity coordinates and the maximum luminance and may be substituted for the virtual primary colors selected of the primary colors and therefore all the pixels have the same virtual primary colors and the color display of the monitor is made uniform.  When the differences between the primary colors and the tristimulus values of the virtual primary colors are small, the relations between input video signals and light source modulation signals are searched in order to make the tristimulus values of the primary colors in the pixels and the tristimulus values of the virtual primary colors identical or analogous. The tristimulus values of the primary colors and the tristimulus values of the virtual primary colors are so set as to coincide or resemble. Further, conversion coefficients are calculated and the input video signals are changed to the light source modulation signals and the drive signals of the primary colors in the monitor are generated by the light source modulation signals.

Title: Manufacturing method for piston for compressor
Inventor: KATO TAKAYUKI
IPC: B23K15/00
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To improve joint strength between a head body part and blocking members manufactured by die casting. SOLUTION: A material for manufacturing a single head piston is provided with a body member 162 and the blocking members 164. The body member 162 and blocking members 164 are cast by a pore-free method, and the gas quantity in material is made 5 cc/100 g or less. Each blocking member 164 is fitted into the opening of the body member 162. Both members are rotated while irradiating electron beams on a weld line with an end face 180 of the body member 162 and a shoulder face 194 of the blocking member 164, as welded faces, and a part near the welded faces is fused to joint both members. Since the gas quantity in the material of the body member 162 and blocking member 164 is suppressed low, a welded bead with few blowholes can be obtained. The electron beams are bifurcated halfway, and the irradiation point of each electron beam moves describing a spiral locus.  Consequently, even if blowholes are once formed in the welded bead during welding, the blowholes are fused being irradiated again with electron beams.

Abstract: PROBLEM TO BE SOLVED: To provide a method for the caustic reduction of polyester fibers having a relatively simple constitution and capable of easily determining the end point of the caustic reduction, and an apparatus for carrying out this method. SOLUTION: Hydrolysis of polyester fibers is carried out through the processes in which the temperature of an aqueous solution of caustic soda for dipping a woven-and-knitted fabric including the polyester fibers is controlled as follows: the temperature is elevated to a specified treating temperature in the period of 0-ta; the specified treating temperature is kept throughout the period of ta-tb; the aqueous solution is cooled in the period of tb-tc. In the hydrolysis, the weight reduction rates are measured in the period of 0-ta, and thereby the course of weight reduction rates, which change roughly along a trapezoid, can be estimated, and accordingly, the point tb when the cooling is started can be calculated so that a specified weight reduction rate is obtained.
