摘要： A bearing steel having long rolling life comprising, by weight, 0.65 to 0.90% of C, 0.15 to 0.50% of Si, 0.15 to 1.0% of Mn and 2.0 to 5.0% of Cr, and the balance of Fe. Austenite grain size can be prevented from becoming coarser to make hardening in high temperature possible by further adding 0.0090 to 0.0200% of N, one or more of 0.010 to 0.050% of Al, and 0.005 to 0.500% of Nb as optional elements to the steel. Further, rolling fatigue life can be improved by further adding one or more of 0.20 to 0.50% of Ni, 0.10 to 2.00% of Mo and 0.05 to 1.00% of V as optional elements, and machinability can be improved by further adding one or more of 0.02 to 0.05% of S, 0.005 to 0.10% of rare earth elements, 0.02 to 0.30% of Pb, 0.0005 to 0.0100% of Ca, 0.001 to 0.200% of Bi, 0.005 to 0.20% of Se and 0.005 to 0.100% of Te in the steel as optional elements.

摘要： A denture attachment is planted in a denture base in such a manner as to oppose a keeper (103) made of a soft magnetic substance, and clamped by the keeper (103) through magnetic attraction. The attachment comprises at least plate-like three yokes made of a soft magnetic substance and at least two plate-like magnets the N and S poles are oriented in the direction of the thickness of the attachment. In the drawing, the attachment comprises a center yoke (10), a first magnet (1), a second magnet (2), a first side yoke (11) and a second side yoke (12). The magnetic poles of the first and second magnet (1, 2) on both sides of the center yoke (10) are characteristically opposed to one another. Therefore, an independent magnetic loop is formed for each magnet. Because of this novel structure, the magnetic force is about twice stronger than conventional while the denture has a compactness required generally. Spacers (21 and 22) made of a non-magnetic substance may cover the surfaces of both magnets (1 and 2) in contact with the keeper (103), and a casing (3) made of a non-magnetic substance may cover the entire portion other than the surfaces in contact with the keeper so as to improve both corrosion resistance and wear resistance.

摘要： In the treatment of rare-earth magnetic powder by exothermic hydrogenation and then endothermic dehydrogenation the heat gain or loss is compensated for by treating a separate material to absorb or emit an equivalent amount of heat to that occurring in the reaction (e.g. by dehydrogenation or hydrogenation of a similar rare-earth magnetic material, in order to stabilize the treatment temperature of the powder.

摘要： The present invention offers a production method for anisotropic resin-bonded magnets with precise dimensions in high productivity. It comprises the aligning step in which the preform is preliminary compression-molded in the preforming molding die 22 in the preforming press 20 with an applied magnetic field to align the magnetization direction of the magnet powder at a temperature in which the thermosetting resin in the compound becomes liquid state, the transferring step in which said preform is transferred from preforming press 20 to densifying molding die 32 in a densifying press 30, and densifying step in which said partly cured preform is compression-molded by applying pressure in a densifying press 30 to obtain desired shape of magnet.

摘要： A mixture of an anisotropic magnetic powder and a temperature setting resin are loaded into a press tool that has upper and lower movable dies to compress the compound in a sleeve 17 while heating is being applied 11. The required orientation of the magnetic particles 16 during the heating and hardening process is determined by a magnetic field applied by coils 12 around the tooling. The maximum magnetic field is applied when the resin has reached the fluid state and is maintained until hardening occurs.
