CONSTITUTION:The horizontal deflecting current is integrated by a resistance Rl and a capacitor C3 to undergo the DC reproduction via resistances R3 and R4 and supplied to a differential amplifier A. So is with the vertical deflecting current. The amplifier A amplifies the differential signal between both signals. The output of the amplifier A is amplified by a CR coupling amplifier circuit having four steps between (c and d), (d end e), (e and f) and (f and g) respectively. The DC component of the output waveform of the amplifier A is cut at the lst step by a capacitor C7 and undergoes the DC reproduction via resistances R7 and R8 and then amplified by a transistor Q1.

Filed: 1983-05-06
Abstract: PURPOSE:To obtain a display having a good color, and to reduce a noise by superposing at least two colors of three primary colors of red, green and blue, and shading a gap of each picture element. CONSTITUTION:A blue mosaic 15, a green mosaic 16 and a red mosaic 17 have areas 18, 19 and 20 superposed on an adjacent color mosaic, respectively, and by superposition of this color mosaic, a gap of a conventional color filter is filled up and shaded from a light. As for a spectral luminous intensity distribution of blue 12, green 13 and red 14, a part where a wavelength distribution of each color is superposed is a very small wavelength area, and its transmittivity is small. Accordingly, the greater part of a light can be shaded by superposing two colors among three primary colors and executing a subtractive color mixture. In case of the subtractive color mixture of blue-green, and the subtractive color mixture of green-red, a weak light transmits, if so much, in the vicinity of 500 nm and in the vicinity of 580nm, respectively, and in case of the subtractive color mixture of red-blue, the light can be shaded almost completely.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that the pH of the alkaline water and acidic water varies with the current strength to an electrolytic cell due to the variation of the conductivity of the water to be electrolyzed by utilizing only the power charge in an accumulating means. SOLUTION: When city water is introduced into an electrolytic water generator by a user, a flow pulse corresponding to the flow rate is outputted to a relay switching part 49 by a flow sensor 12. The flow rate is measured herein, and, when the measured value exceeds a specified flow rate, the switch of the output of an energization signal to the relays 45 and 46 to the output stop is repeated every specified time. Consequently, the power accumulated in a capacitor 47 or 48 is supplied to an electrolytic cell 8, and the city water is electrolyzed. At this time, the electrolysis of the city water continues over a long time when the conductivity of the city water is low, the power supplied to the cell 8 is kept constant for a specified time, and hence the pH is fixed at all times.
