摘要： The present invention is a sliding contact material having a composition of Cu of 6.0% by mass or more and 9.0% by mass or less, Ni of 0.1% by mass or more and 2.0% by mass or less, an additive element M of 0.1% by mass or more and 0.8% by mass or less, and the balance being Ag. The additive element M is at least one element selected from the group consisting of Sm, La and Zr. The present sliding contact material has a material structure in which dispersion particles containing an intermetallic compound containing at least both Ni and an additive element M are dispersed in an Ag alloy matrix. It is required that the ratio of a Ni content (% by mass) and a content of an additive element M (% by mass) (KNi/KM) in the dispersion particles falls within a predetermined range. The present invention is an Ag alloy-based sliding contact material more excellent also in abrasion resistance than conventional ones, and a material adaptable to higher rotation numbers of micromotors.

摘要： A carbonaceous material is fabricated by kneading of carbon powder and a binder. The carbonaceous material is granulated such that an average particle diameter of the carbonaceous material is 0.3 mm or more. A brush material is fabricated by mixing of the granulated carbonaceous material and metallic powder. A ratio of the metallic powder to a total weight of the brush material is adjusted to 1% by weight or more and 30% by weight or less. Pressure molding is performed on the fabricated brush material, and thermal processing is further performed on the brush material at a temperature at which a resin in the brush material is not carbonized.

摘要： A canted coil spring made from multi-metallic wire to achieve combinations of desired material characteristics of different metals is discussed. Wire to be used in canted coil springs can have two or more metals oriented co-axially along such wire, such as an outer layer of one metal having one set of properties, and a core of a different metal having a different set of properties, that will achieve a single solid, multi-metallic wire with enhanced performance over a single material canted coil spring. Such features may be found advantageous in electrical applications, such as where both high electrical conductivity and high strength properties are desired.

摘要： A rotating electrical machine, which is a direct current motor, includes carbon brushes. Each carbon brush contains graphite grains, metal particles, and solid lubricant, which are sintered in a dispersed state. The graphite grains are each formed of granulated substance of raw graphite particles, and the particle diameters of the graphite grains are within a range of 60 to 280 μm. The surface of the granulated substance is coated with amorphous carbon made of carbides of organic binder. A plurality of holes are formed in each carbon brush. The dimension (maximum dimension) of the holes is less than half the average particle diameter of the raw graphite particles.

摘要： In the present invention, by selecting an optimum combination of plating layer materials or materials, not only the manufacturing cost of motor brush is reduced but also a plating layer having excellent characteristics is formed in a narrow width on the surface of brush base material so as to have a predetermined thickness. The present invention is formed by a brush sliding portion that slides on a motor commutator and a plate-shaped brush base material that is slender as a whole and supports the brush sliding portion. This brush sliding portion is formed by Pd plating portion formed over a predetermined length on a part in the lengthwise direction of the brush base material that supports the brush sliding portion. This Pd plating is applied on the brush base material via backing Ni plating.
