    摘要： Ceramics material are not resistant to tensile force, though they are resistant to compression force. Therefore, ceramics materials, when used as the material of a commutator of an electric rotary machine, tends to be cracked and broken due to tensile stress generated in the inner peripheral portion of the commutator when the latter is press-fitted on the rotor shaft of the machine. The invention is aimed at obviating the above-described problem, so as to make it possible to produce a sliding current collector of an electric rotary machine from a ceramics material. To this end, according to the invention, an annular gap is formed between the inner peripheral surface of the ceramics commutator and the other peripheral surface of the rotary shaft and the gap is filled with a resin such as a thermosetting resin which is then thermally set to form a resin layer by which the commutator is bonded to the rotor shaft. The resin layer effectively absorbs any tensile stress which may otherwise be caused in the inner peripheral portion of the commutator due to, for example, thermal expansion of the rotor shaft. It is thus possible to securely fix the commutator to the rotor shaft without risk of cracking or damaging of the commutator.

    摘要： A commutator has a central support supporting a plurality of conductive segments separated by a plurality of insulative segments. In addition to providing an insulative function between the conductive segments, the dielectric constant, the area, and the thickness of the insulative segments are chosen so that they provide a capacitive effect, which capacitive effect suppresses current peaks during operation of the commutator. Preferably, the dielectric constant is greater than 10. The central support may include a metal shaft and an insulating ring, which insulating ring is preferably of material with a lower dielectric constant thereby to suppress-shorting between the shaft and the conductive segments. It is particularly advantageous if the conductive and insulative segments are of ceramics material since this provides good wear resistance. In further alternatives, capacitors are formed between the conductive segments by rings or other bodies of insulative materials of a suitably high dielectric constant.

    摘要： A sliding current collector comprises a pair of sliding members which are slidable relative to each other for supply and reception of current through sliding surfaces of the paired sliding members wherein the two sliding members are made of conductive ceramics, and the sliding surface of each of the sliding members has a film surface made of a soft conductive material which is softer than the conductive ceramics so that the sliding current collector can suppress variations in contact voltage drop across the sliding surfaces.

    摘要： A vibration isolation mechanism for a coil spring, according to the invention, includes a spring retainer 24 that supports a return spring 20. The spring retainer 24 comprises a pedestal retainer 25 and a holding retainer 26. A seat winding portion 20a of the return spring 20 is elastically and firmly held between a holding portion 30a of the pedestal retainer 25 and holding portions 31a of the holding retainer 26. Accordingly, vibrations of the return spring 20 are forcedly damped, so that the generation of an abnormal noise caused by vibrations of the return spring 20 is suppressed even when a minute clearance is present between the seat winding portion 20a and a second turn portion of the return spring 20.
