Title: Manufacture of alkaline battery
Inventor: NAGAMINE AKIO
IPC: H01M4/62
Filed: 1979-10-09
Abstract: PURPOSE:To facilitate the mixing of the positive components and equalize the mixed distribution of the positive electrode of an alkaline battery by allowing silver ions and an alkali solution to react and obtaining a moist silver oxide, mixing the moist silver oxide with the binder of a cross- linked acrylic-resin solution, and followed by drying the mixture to obtain the positive electrode. CONSTITUTION:A silver-ion solution and an alkali solution are allowed to react to obtain a moist silver oxide containing water. The moist silver oxide is added with the binder of a cross-linked acrylic-resin solution, and these two components are mixed, before the mixture is dried and crushed to obtain a positive-mixture powder. A sodium acrylate is preferred as the cross-linked acrylic-resin, and the ratio of the sodium acrylate to the silver oxide which is expressed in percentage should be 0.2-2.0wt%. For instance, a water solution containing 10kg silver nitrate, and a water solution containing 2.5kg sodium hydroxide are allowed to react to precipitate silver oxide. The precipitated silver oxide is washed with water and filtrated, before the filtrated silver oxide is mixed with a cross-linked sodium acrylate and a flake-graphite powder. The thus obtained mixture is dried at 85 deg.C in a carbon-dioxide-free air before it is crushed to prepare a positive- mixture powder 2. Thus, a positive-mixture powder with an equalized mixed distribution can be easily obtained.

Title: Method of evaluating edge cracking property of metallic sheet
Inventor: MURAYAMA RIICHI
IPC: G01N29/07
Filed: 1988-05-30
Abstract: PURPOSE:To evaluate the edge cracking property of a metallic sheet with high accuracy by determining the intra-surface orientation difference of a plastic strain ratio by a non-destructive measurement by a regression equation using two expansion coeffts. CONSTITUTION:The ultrasonic plate waves of an So mode are propagated at a specified distance in the rolled metallic sheet in the three directions, the rolling direction, the direction inclined by 45 deg. with the rolling direction and the direction orthogonal with the rolling direction and the times of the respective propagations are measured. The main crystal orientation components of the metallic sheet are derived by using the measured values, by which the intra-surface orientation difference DELTAgamma of the plastic strain ratio is determined from the equation. The plastic strain ratio is determined by propagating the ultrasonic waves directly in the metallic sheet without drawing a test piece and sample from the metallic sheet and, therefore, the evaluation by the adequate non-destructive measurement is enabled as an online evaluation method. Since the value of the intra-surface orientation difference DELTAgamma can be estimated by the regression equation of the two expansion coeffts., the intra-surface orientation difference DELTAgamma is determined with the good accuracy.
