CONSTITUTION:In a positive electrode for a flat type cell in which a positive electrode active material 3 is carried by a positive electrode core member 2, the positive electrode core member 2 is made up out of a me...

PURPOSE:To prevent voltage from being lowered by interposing a hold ring for electrolyte at the upper section of a positive electrode. CONSTITUTION:A positive electrode 3 which is formed while the mixture of manganese dioxides and grapgite are molded with pressure, is inserted into the inside of a positive electrode case 2 which is a drawn can made of stainless steel, so as to be pressed with pres...

PURPOSE:To keep internal resistance low as well as to reduce scatter in said resistance by interposing a metallic positive electrode ring in a L-shape provided with a specified surface roughness between a positive electrode and a cell case in such a way that the bottom surface of it comes in contact with the cell case. CONSTITUTION:The bottom surface 6a of the brim section of a positive electrode ...

PURPOSE:To realize a long service life and a high reliability by changing the structure of a positive electrode lid making an aluminum clad member contacted to a positive electrode active substance. CONSTITUTION:The battery is composed not to contact directly a positive electrode active substance 7 (sodiumpolysulfide and sulphur vapor) and the core member 4' of a positive electrode lid 4. And as t...

PURPOSE:To avoid the generation of an imperfect discharge by connecting discharge resistance units responding to the battery stacks by using multipole connector devices. CONSTITUTION:By connecting multipole connectors (CN) 72 and 78, exclusive discharge resistance units 74a, 74b,...74n-1 are connected to battery stacks 64a, 64b,...64n-1 respectively, and the stacks 64 and the resistance units 74 a...

PURPOSE:To prevent the generation of a reverse charging by converting plural battery stacks to the parallel connection condition to a discharge resistance with a switching relay in a perfect discharge time. CONSTITUTION:In a perfect discharge time to remove the separated zinc, a terminal 68 is converted to a terminal 83 side, a load resistor 72 for perfect discharge and a power source 74 for switc...

PURPOSE:To surely forecast the degradation in operating efficiency with the anaerobic fermentation apparatus with a high sensitivity by keeping measuring the adenosine triphosphate quantity in anaerobic fermentation treated water and occasionally adjusting various fermentation conditions in accordance with the results thereof. CONSTITUTION:The concn. of the adenosine triphosphate(ATP) is measured ...
