Abstract: PURPOSE:To improve the specific resistance of the panel and to obtain the liquid crystal panel having a high grade without having unequal display by dispersing or disposing scattering materials consisting of a material having ion adsorptivity or having the material having the ion adsorptivity on the surface into the cell. CONSTITUTION:The particulate or fibrous scattering materials 8, etc., which consist of the material such as ion exchange resin, chelate resin, cellulose or cellulose deriv. having the ion adsorptivity and having the grain size or diameter smaller than the gap thickness are dispersed or disposed into the cell 2 of the panel.

Abstract: PURPOSE:To prevent deterioration of ion control characteristic from being generated by formation of a surface charge due to adhesion of ion to an inside surface of an aperture of an insulator substrate by a method wherein the aperture of the insulator substrate is made larger than, at least one side aperture of two electrode boards. CONSTITUTION:A size of an aperture 5A of an insulator substrate 2 of an ion flow control board 1A is made larger than aperture 6 of electrode board 3, 4.

For manufacture of the ion flow control board 1A, metallic layers 3, 4 are formed on both surfaces of the insulator substrate 2, are etched by using a first etching liquid, and the aperture 6 is formed to the metallic layers 3, 4. Etching is performed through the aperture 6 by using a second etching liquid which does not act on the metal lic layer 3, 4 and dissolves only the insulator substrate 2, and the aperture 5 is formed to the insulator substrate 2. In that case, a diameter of the aperture 5A is made larger than a diameter of the aperture 6 by using enough etching time.

These two direct currents are passed through regulators 6, 7 respectively and are adjusted so that the two direct current voltages of the phases of ripple voltages differing by 30° become equal, after which both voltages are synthesized in a synthesis circuit 8. Thereby, ripples may be suppressed to about 1/4 and filter circuits may be miniaturized or made unnecessary, thus high detection accuracy may be provided with less detection time delay

Abstract: PURPOSE:To measure real chromaticity, real turbidity and apparent chromaticity by applying operational processing to a chromaticity signal or a signal of light within a wavelength band changing by chromaticity and turbid matter and a turbidity signal or a signal of light within a wavelength band changing by turbid matter. CONSTITUTION:Both of chromaticity and turbidity are simultaneously measured to obtain a chromaticity signal or a signal (absorbancy signal) of light, for example, within a wavelength band of 390nm receiving attenuation by chromaticity and turbid matter, that is, changing by chromaticity and the turbid matter from a means A. A turbidity signal or a signal (absorbancy) of light, for example, within a wavelength band of 660nm receiving attenuation only by the turbid matter, that is, changing by the turbid matter is obtained from a means B. These two signals are received by an operational processing means C to be subjected to operational processing to obtain real chromaticity CT, real turbidity T and apparent chromaticity CS. At this time, the chromaticity CS is calculated by an operation formula SC=f(CT,T). Further, a table composed of a combination of the respective data of the turbidity T and the chromaticity CT is preliminarily obtained by experiment and the chromaticity CS may be calculated from the data of the corresponding position of the table on the basis of the input signals from the means A, B.
