摘要： A zinc alloy containing Al, Bi and In is reduced to particles by gas atomization and sieved to prepare a zinc alloy powder. A polyacrylic acid powder and a magnesium hydroxide powder are added to the zinc alloy powder and the ingredients are mixed to make an anode composition. Zinc oxide is added to an aqueous KOH solution to prepare a liquid electrolyte which is mixed with the anode composition under stirring to make a gelled anode composition that has improved performance in pulsed discharge to get large current without increasing the evolution of hydrogen gas.

摘要： A paste of brazing material of AgnullCunullTinullTiO2 system is printed to both sides of an AlN substrate; a copper sheet is then placed on both sides and heated in vacuum to be joined to the substrate. A resist having a desired-circuit pattern is coated on the surface of each copper sheet and etching is performed. A solution containing a mixture of EDTA, ammonia and aqueous hydrogen peroxide is then applied to dissolve away the unwanted brazing material and the like from between the circuit patterns without corroding the ceramic substrate and the metal sheet.

摘要： A sliding member having excellent seizure resistance comprising a metallic member provided with a sulfide-based solid lubricating layer on the sliding surface thereof is provided, characterized in that the interface of the metallic member in contact with said solid lubricating layer is provided with a surface roughness Rmax of 1 nullm or higher. The sliding member above is obtained by preparing an aqueous solution dissolved therein one or two types or more of thiocyanates or thiosulfates of alkali metals or alkaline earth metals, and by performing electrolytic treatment in which a steel member the surface roughness thereof is controlled is used as the anode. In this manner, an iron sulfide based layer is formed on the surface of the steel member by using the Fe component derived from the steel and the S component from the solution as the reacting agents.

摘要： In one method, a zinc concentrate is leached as elemental sulfur and other by-products are stripped from the surfaces of the particles in the concentrate by means of a grinding machine such as a ball mill. The ferric ion consumed by leaching is regenerated for recycled use by introducing oxygen into the post-leaching solution flowing through feed pipes. This method can shorten the leach time by a substantial degree. In another leaching method, a solution containing free sulfuric acid and ferrous ions and a zinc concentrate are charged into an autoclave having a pressurized atmosphere and as oxygen gas is supplied, the internal temperature is adjusted between 90 null C. and 120 null C., whereby the ferrous ion in the solution is oxidized to increase the ferric ion concentration to 2-60 g/L whereas pressurized leaching of the zinc concentrate is performed simultaneously. Following this one-step oxidative leaching process, the resulting slurry is subjected to a grinding/leaching step in which by-product elemental sulfur is stripped from the surfaces of the particles in the leached zinc concentrate and, thereafter, the slurry from the grinding/leaching step is subjected to another pressurized leaching step.

摘要： Copper alloy having the basic composition CunullZnnullSn contains 23-28 wt % Zn and 0.3-1.8 wt % Sn and satisfies the relation 6.0null0.25XnullYnull8.5 (where X is the addition of Zn in wt % and Y is the addition of Sn in wt %). The alloy is cast into an ingot by melting and cooling over the range from the liquidus line to 600null C. at a rate of at least 50null C./min; the ingot is hot rolled at a temperature not higher than 900null C. and then subjected to repeated cycles of cold rolling and annealing at 300-650null C. to control the size of crystal grains, thereby producing a rolled strip having a 0.2% yield strength of at least 600 N/mm2, a tensile strength of at least 650 N/mm2, an electrical conductivity of at least 20% IACS, a Young's modulus of no more than 120 kN/mm2 and a percent stress relaxation of no more than 20%.
