Title: Method for electrolysis of alkali metal salt solution
Inventor: KURUMAYA MASAAKI
IPC: C25B1/46
Filed: 1979-05-14
Abstract: PURPOSE:To prevent the rapid rise of cell voltage and the decrease of current efficiency when crudely purified solution is used in electrolysis of the alkali metal salt solution using an ion exchange membrane by a method wherein liquid in anode chamber is maintained at a specific pH and current is passed intermittently. CONSTITUTION:The alkali metal salt solution is roughly treated by a single filter or by settlement using sodium hydroxide or sodium carbonate and therefore contains 3 ppm or more Ca ions. Such solution is introduced into the anode chamber of the ion-exchange membrane type alkali metal salt electrolysis tank, and is subject to electrolysis by intermittently passing current. In this process, the current is halted until Ca ions are dissolved into the anode chamber and reached to sufficient equilibrium, meanwhile solution supply is contained at least in quantity equivalent to the volume of the anode chamber so that the liquid in the chamber is maintained pH 4 or more. The method remorkably relaxes the cell voltage rise and prevents the decrease in current efficiency.

Title: Operation of reheat steam turbine plant
Inventor: OTOME TOSHIOMI
IPC: F01K7/24
Filed: 1984-03-27
Abstract: PURPOSE:To keep the thermal stress of the rotor of high-pressure exhaust stage and the strength of blades at a sufficiently safe level by increasing the flow rate of main steam beyond that of reheat steam during the no-load or low-load period of a reheat steam turine. CONSTITUTION:The error signal DELTAN of set revolving numers 30 and actual revolving number 31 is multiplied by an intercept valve constant 32, a lower limit valve constant 33, and a main steam stop valve constant 34. By a function generator 38, the flow rate ratio between the main steam and the reheat steam is obtained from the main steam temperature 36 and the reheat steam pressure 37. The flow rate of the main steam is increased beyond that of the reheat steam during the no-load or low-load period of the reheat steam turbine, and as the reheat steam turbine becomes of high loads, the flow rate of the reheat steam is allowed to approach that of the main steam. The thermal stress of the rotor in high-pressure exhaust portion can thus be reduced, and the strength of the blades, etc., of high-pressure exhaust stage can be sufficiently kept.

Filed: 1978-05-17
Abstract: PURPOSE: To enable a simple circuit with space filter effect to separate a composite color TV video signal into a luminance component and chromaticity component.  
     CONSTITUTION: A composite video signal from input terminal 10 is inputted to delay line 11 with delay time (τ) for one horizontal period of a TV signal and its output is inputted to delay line 12 with the same delay time. Then, adder 13 obtains a wave of e jωt +e -jωt =2cosωt, which is applied to the 2nd adders 14 and 15; the output of adder 14 is expressed by 1+cosωt while that of adder 15 is by 1- cosωt with output characteristics (a) and (b) upside-down each other, and (a) and (b) represent the chromaticity and filter characteristics for color signals respectively. Since the color signal component has a fixed band while characteristic (a) has no low-frequency component, the low-frequency component of characteristic (b) is extracted by filter 16 and varied by coefficient unit 17 so as to vary the vertical resolution, so that a luminance signal component with the space filter effect improved will be obtained from adder 18.
