Title: Enclosed alkaline storage battery
Inventor: NAKATANI KENSUKE
IPC: H01M10/52
Filed: 1986-06-06
Abstract: PURPOSE:To make the built-up of cell charging voltage at the time of full charging as well as to detect a voltage variation at the time of the full charging so easily and accurately, by constituting the uncharged capacity of an anode in a discharged state to be smaller that the uncharged capacity of a cathode. CONSTITUTION:The uncharged capacity of an anode at a discharged state is constituted to be smaller in substance than the uncharged capacity of a cathode, and at the time of charging, the anode is full charged earlier than the cathode. Therefore, a variation in cell charging voltage at the time of full charging is made larger by the large build-up of the anode to hydrogen generating potentional. With this constitution, such charging control as utilizing the voltage variation is made performable easily and accurately so that constant current-constant voltage charging can be done.

Filed: 1979-10-17
Abstract: PURPOSE: To ppt. and to remove algae effectively, by controlling the injection ratio of a flocculant in accordance with the measurement of alkalinity of raw water in control unit for the injection of chemicals of water treatment plant.  
     CONSTITUTION: The injection ratio of flocculant is increased in accordance with the measurement of the increase in alkalinity of raw water due to the multiplication of algae. The turbidity 7 of raw water in a water reservoir 1 is fed to an arithmetic unit 10 for injection ratio of flocculant in order to obtain the injection ratio α 1  of the flocculant. When algae are multiplicated, the alkalinity 11 of raw water is compared with a prescribed value to find the difference, which is fed to an arithmetic unit 13. The arithmetic unit 13 calculates the output α 2  of the arithmetic unit according to the prescribed formula. The α 1  and the α 2  are added by an adder 14 thereby obtaining the injection ratio α of flocculant. The α is multiplied with the raw water flow rate 2 by a multiplier 9, hereby injection ratio of flocculant is obtained and the flocculant is injected from a flocculant injection machine 8. Hereby raw water deteriorated by the multiplication of algae is treated effectively.
