摘要： A method for producing a rare earth element sintered magnet which comprises applying a metal plating onto a Sm2Co17 type or R2Fe14B type magnet and then subjecting the resultant product to a heat treatment, or which comprises forming a metal oxide or nitride layer on the above metal plating layer or directly on the magnet. The method allows the production of a rare earth element sintered magnet being free from hydrogen embrittlement.

摘要： The disclosed cemented carbide base outer blade cutting wheel comprises a base in the form of an annular thin disc of cemented carbide, and a blade section on the outer periphery of the base. The blade section contains: diamond and/or CBN abrasive grains pre-coated with a magnetic material; a metal or alloy bond formed by electroplating or electroless plating for bonding abrasive grains together and to the base; a resin infiltrated between abrasive grains and between abrasive grains and the base, said resin being a thermoplastic resin having a melting point of up to 350ø C. or a thermoset resin obtained by curing a liquid thermosetting resin composition having a curing temperature of up to 350ø C. The method for manufacturing said outer blade cutting wheel is also disclosed.

摘要： Provided is an alloy powder having a narrow particle size distribution centering about a desired particle diameter and containing small amounts of finer and coarser particles, whereby the variation in characteristics resulting from differences in alloy particle size is eliminated and, moreover, the problems arising from cracking and particle size reduction induced in the alloy by the absorption and release of hydrogen are solved. More specifically, provided is an AB5 type hydrogen absorbing alloy powder obtained by quenching a melt of a hydrogen absorbing alloy rapidly and subjecting the resulting hydrogen absorbing alloy to fracturing by absorbing hydrogen, wherein the particle size distribution of the hydrogen absorbing alloy powder is such that, when the frequencies of detection of various particle diameters are cumulatively added from smaller-diameter to larger-diameter particles, and the particle diameters corresponding to 10%, 50% and 90% of all particles are represented by D10, D50 and D90, respectively, the values of D10, D50 and D90 fall within the respective ranges defined by 4 mu m

摘要： A sintered magnet sawing apparatus is provided comprising a cylindrical work carrier mounted on a horizontal rotating spindle and having a regular polygonal shape in a perpendicular cross section, and a plurality of endless belts adapted to force a work of sintered magnet against the carrier surface to secure the work thereto and adapted to travel synchronously with and counter to the rotation of the carrier in a circulatory manner. In accordance with rotation of the carrier, the work is delivered to the peripheral surface of the carrier, secured thereto by the elastic belts, moved further forward and cutoff machined by an outer cutoff blade. The divided work is moved further forward, released and discharged from the carrier.
