摘要： The moving slip ring surface of electrical machinery transfers electrical current by contact thereof with liquid metal directly or through the tips of a plurality of closely spaced brushes positioned along the bottom of a housing under pressure within which the liquid metal is contained. The brush tips are respectively connected to lower ends of fibers electrically interconnected within the housing and exposed to the liquefied metal received and retained within the housing. According to one embodiment, the liquefied metal is retained within containment material filling the housing for contact exposure of the fibers therewith. According to another embodiment, exposure of the fibers to the liquefied metal within the housing is effected by entry of the liquefied metal into hollow brush tubes connected to and extending from the bottom of the housing, through which stem portions of the fibers extend to the brush tips.

摘要： Molybdenum disulfide, tungsten disulfide or the like as a solid lubricant and any of alumina, silica, silicon carbide or the like as an abrasive are added to filter graphite. A metal of good electric conductor is coated over the whole surface of a carbon brush material except a part of the carbon brush material to be contacted with a commutator. When the commutator rotates clockwise, a metal coating of the good electric conductor is removed mechanically from at least a part of at least either of a left side surface or a right side surface.

摘要： In an ordinary DC motor in a windshield wiper, operating speed tends to increase as the motor brushes become seated. The invention counteracts this tendency by providing a brush geometry which causes the effective angular position of a brush to change during seating. The change is in a direction which tends to reduce speed.

摘要： A vibration-damping device for miniature motor brushgear comprising brush arms having sliding parts at the tips of a plurality of fork-like prongs, terminals and brush bases; the brush bases are supported by a motor case cover and the brush arm sliding parts make sliding contact with a motor commutator by the resiliency of the brush arm in which a soft photo-setting resin is applied on areas at the tips of the brush arms, other than the sliding parts, in such a manner that the fork-like prongs and/or gaps between the prongs are covered by the soft photo-setting resin. The fork-like prongs are individually and separately movable by controlling the flexibility of the soft photo-setting resin, by setting the coating weight or hardness after cure of the soft photo-setting resin to a predetermined value, or by applying soft photo-setting resin having different hardness values in multiple layers.
