Abstract: PURPOSE:To generate ozone with maximum efficiency, to prevent accidents and to control the deterioration of an electrode by electrolyzing water with the PbO2-coated electrode, continuously measuring the temp. of an electrolyte and holding the electrolyte in a specified set temp. range. CONSTITUTION:An electrolytic cell 1 is separated into an anode chamber 5 and a cathode chamber 6 by coating the anode surface of a diaphragm 4 with PbO2 and the cathode surface with Pt 3. Pure water is charged into the cell 1, and a current is applied to electrolyze water. Consequently, an gaseous O2 and O3 mixture is generated from the anode chamber and recovered. A sensor 7 is set in the anode chamber 5 in this electrolysis reaction to continuously measure the temp. of an anolyte. When the temp. of anolyte deviates from the preset temp. of 20-35 deg.C or preferably 23-30 deg.C, the temp. is returned within the range. As a means for returning the temp., the electrolyte, especially the anolyte, is passed through a circulating line 9 by a circulating pump 8 and circulated to the outside of the cell 1 and cooled, if necessary, or the current is reduced. O3 is generated with maximum efficiency in this way, the occurrence of accidents resulting from the fluctuation of the liq. temp. is supervised, and the deterioration of PbO2 at high temp. is obviated.

Title: Circulating type noise reducer circuit
Inventor: KITAURA MASAHIRO
IPC: H04B1/10
Filed: 1988-02-13
Abstract: PURPOSE:To reduce the noise without damaging signal components as soon as possible by multiplying signal components by optimum coefficients of 0-1 correspondingly to plural frequency band areas. CONSTITUTION:A signal Y circulated once during one frame is inputted to an input terminal 1. With respect to the operation to signal components of the signal Y, the output obtained by subtracting the input signal from the signal of one frame before as the output of a one-frame memory 3 by a first subtractor 4 is a differential value in one frame. This differential value in one frame is a noise component free from correlations.
