Abstract: PURPOSE:To lower voltage and to enhance current efficiency and to simplify a production process by utilizing an anion exchange resin membrane for a diaphragm of an anolyte and a catholyte in the case of electrolytically producing ammonium peroxydisulfate. CONSTITUTION:In a method for electrolyzing the aq. soln. of sulfate ion accompanied with protons or ammonium ions to produce ammonium peroxydisulfate, the interval between an anode and a cathode is comparted by an anion exchange membrane. As the anion exchange membrane, the various-type membranes are utilized but the membrane is especially preferably utilized wherein it has quaternary ammonium group and a main chain consists of a perfluorocarbon polymer. The need for withdrawal and replenishment of a catholyte, return to an anode chamber, liquid regulation correspondent thereto and concentration of excess water brought into the anode chamber is eliminated by this method. Ammonium peroxydisulfate is produced at high current efficiency. Further, diaphragm resistance is low and even when an electrode is closely stuck to the diaphragm, current efficiency is not deteriorated.

Abstract: PROBLEM TO BE SOLVED: To provide a video reproducing device capable of increasing apparent variation of a video without increasing the number of videos themselves. SOLUTION: Video information selected as a specification order 1 is outputted as it is without video processing since a color flag D3 and a brightness flag D4 are zero also.
