Inventor: UNISHI MASAKI
IPC: G03G15/08
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To reduce the consumption of a black coloring material without deteriorating the printing quality, by printing a place without a deterioration in the pointing quality with a black of color mixture and the other place with a black of single color. SOLUTION: Even if the amount of black toner is smaller than a specified amount and a black of color mixture is substituted for a black of single color, the place without the deterioration in the printing quality is printed with the black of color mixture, so that the consumption of the black toner as the black coloring material can be suppressed without deteriorating the printing quality and printing can be executed longer. In other words, a character of a size smaller than a fixed size is printed by the black of color mixture instead of the black of single color. Therefore, also the reduction of the black toner can be suppressed without deteriorating the printing quality. Further, when yellow, magenta and cyan toners as the black coloring material of the color mixture and the black toner as the black coloring material of the single color make one set, the consumption of the black coloring material of the single color is reduced to make effective use of the black coloring material of the color mixture.

Title: Methacrylic resin as material for optical disc
Inventor: UCHIDA HIROYUKI
IPC: G02B1/04
Filed: 1988-03-11
Abstract: PURPOSE:To inhibit generation of minute foams after the formation of a base plate of an optical disc comprising methacrylic resin by carrying out suspension polymn. of a reaction mixture consisting of a monomeric methyl methacrylate, and ethyl or methyl acrylate contg. a specified amt. of polymn. stabilizing additive comprising sodium sulfate or sodium phosphate. CONSTITUTION:In a polymn. stage carried out for obtg. polymethyl methacrylate (PMMA) by a suspension polymn. process, a reaction mixture consisting of 100pts.wt. monomeric methyl methacrylate and ethyl or methyl acrylate and 0.15-0.25pts.wt. sodium sulfate or sodium phosphate as polymn. stabilizing additive, is subjected to suspension polymn. Minute foams in a base plate are reduced remarkably if the amt. of the polymn. stabilizing additive is reduced to <=0.25pts.wt., but sufficient suspension polymn. reaction is not attained if the added amt. is too little. Therefore, the lower limit of the added amt. is necessary to be >=0.15pts.wt. The base plate comprising the PMMA obtd. by this method is quite suitable for a material of an optical disc because minute foams which cause color flash are reduced remarkably.

Abstract: PROBLEM TO BE SOLVED: To interpolate a chrominance signal for a video excess input signal by using a frame memory so as to detect the chrominance signal based on a difference between the video excess signal and its spatially and timewise adjacent signal. SOLUTION: Output signals from CCDs 2-4 are respectively amplified by amplifiers 5-7 and given to peak clip circuits 11-13 and stored in a frame memory 9. Excess signal parts among the stored video signals are detected by a peak detection circuit 10 for each frame. A CPU 8 divides adjacent signals of the video excess signals received from the frame memory 9 into plural stages and obtains a difference between the video excess signal and the adjacent signal to obtain a chrominance signal from the result of the difference. Furthermore, the CPU 8 obtains a chrominance signal based on a difference of video signals due to a timewise change of video excess signals over several frames. Either of the chrominance signals as above is used for a chrominance signal to interpolate the video excess signal and the chrominance signal is superimposed on the video excess signal by amplifiers 14-16.
