Title: Production of hard alloy by electroless plating
Inventor: FUKUHARA MIKIO
IPC: B22F1/08
Filed: 1981-06-18
Abstract: PURPOSE:To obtain an alloy of high strength without addition of lubricants and half sintering stages by coating a metal or an alloy on the surface of hard powder particles by electroless plating then molding the particles and sintering the moldings. CONSTITUTION:A coating layer consisting of a metal or an alloy is formed by electroless plating on the surfaces of hard powder particles consisting of >=1 kind of carbides, nitrides, borides, sulfides, silicides and oxides. After such powder is dried, it is molded by pressing and if necessary, the moldings are sintered after the molding. Since the resultant hard alloy is not added with any lubricant, it has no cavities that may be produced on account of the irregular dispersion of the lubricants. In addition, there is no need for half sintering stages and therefore the variances in the amts. of carbon and oxygen in the hard alloy that may occur in said stages are eliminated. These result in the improved strength of the alloy and the reduced variances in alloy characteristics, thus the reliable hard alloy is obtained. The coating layer makes low temp. sintering possible and improves the mechanical properties of the hard alloy.

Title: Lead storage battery comprising cell having electrolyte uniforming device
Inventor: YONEZU KUNIO
IPC: H01M2/38
Filed: 1981-06-17
Abstract: PURPOSE:An electrolyte stirring device of a lead acid battery, often used in deep discharge state, such as for an electric car or a forklift. CONSTITUTION:Figure 1 shows a container, 2 an electrolyte, 3 a porous tube, whose lower end 4 is closed and upper end 5 is connected in airtightness to a guide tube 6 which is connected in airtightness with a gas path 7 outside a cell. The pore size of the porous tube 3 should be selected in such a way that the electrolyte or air can transmit but the resistance of air transmission through the pore is larger than that of air supply inside the tube. When air is supplied from the gas path 7, the air is pushed out from the whole surfaces of the porous tube 3 in a form of fine bubble, and rises up slowly within the electrolyte. If the upper part of the electrolyte becomes low specific gravity and the lower part of it becomes high specific gravity, a great number of fine bubbles rise up with thin layer of the high specific gravity electrolyte of their surroundings. Therefore, the concentration difference of the electrolyte can be effectively elminiated.
