Title: Manufacture of alkaline battery
Inventor: NAGAMINE AKIO
IPC: H01M4/06
Filed: 1981-09-28
Abstract: PURPOSE:To prevent any overflow of electrolyte during the assembly of an alkaline battery, and enhance the preservation and the battery characteristics by improving the manufacturing process of a negative zinc electrode. CONSTITUTION:After a positive mixture 2 is packed on the bottom of a positive case 1, a separator 3 is stacked over the mixture 2. Next, the opening 1a of the case 1 is sealed with a negative case 5 which is packed with a negative zinc electrode 4. The negative electrode 4 is made by satisfactorily mixing a mixture containing zinc powder, a gelling agent and water by stirring, and humidifying the mixture, being followed by drying the mixture under a reduced pressure so as to form a film of the gelling agent over the surface of the zinc powder. When a filler powder which is insoluble in an alkaline electrolyte and doesn't produce any hydrogen gas when it becomes in contact with zinc is mixed into the above mixture, the gelling speed is further increased, and the reaction surface area of the zinc particles is increased. When a surfactant is added to the above mixture in addition to the filler powder, any overflow of the electrolyte can be prevented due to the increased speed of the gelling of the negative electrode 4 which is caused by addition of the electrolyte after the electrode 4 is packed into the case 5.

Abstract: PURPOSE:To prevent the damage of a corner part in a substrate edge part and to obtain a stable magnetic characteristic by giving a chamfering part for a substrate edge surface and specifying an angle which the surface of the chamfering part and the surface of the substrate make. CONSTITUTION:The substrate 1 consists of an information recording part 2 and a hole part 3 and the corner part of the edge part 4 is chamfered. Here, the angle theta formed by the surface 20 of the chamfering part and the surface 22 of the substrate is set to be 120-150 deg.. When the angle theta is below 120 deg., a width remained as the edge part 4 is narrowed and there is a fear that the edge part 4 is damaged by the holding means of an automatic device. When the angle theta exceeds 150 deg., an effect by chamfering is not given and the corner part of the edge part 4 is damaged by the holding means of the automatic device. Thus, the damage of the corner part of the substrate edge part 4 owing to carry and maintenance can be prevented, and the stable magnetic characteristic is obtained.
