摘要:
An electric rotary machine (for example, a dynamoelectric machine) having a superconducting rotor is disclosed in which an outer shielding member for protecting a superconducting field winding from the influence of the magnetic flux from the stator side and for interrupting heat radiated from the normal temperature side is made of a nickel alloy containing not more than 0.3% carbon, not more than 1% silicon, not more than 2% manganese, not more than 1.5% titanium, from 2 to 8% aluminum, from 8 to 40% copper, and not less than 55% nickel for the balance by weight. The nickel alloy has a structure that a .gamma.'-phase precipitation is formed by aging in an austenitic matrix, and is non-magnetic at 20.degree. C.

A gas turbine combustor defines a combustion chamber for combustion of injected fuel and for introduction of the resultant hot combustion gas to nozzles of a gas turbine. The combustor has parts subjected to hot combustion gas during operation of the turbine, such as a cap connected to a fuel injection nozzle, a liner connected to the cap, and a transition piece connected to the liner. These parts subjected to the hot combustion gas are made from an alloy having a composition consisting essentially of 0.02 to 0.2 wt % of C, 15 to 30 wt % of Cr and 10 to 25 wt % of W.

A shape memory alloy pipe coupling in the present invention for joining two pipes, the pipe coupling comprising a tube of a shape memory alloy, and a cover of stainless steel having a sufficient thickness and having high corrosion resistance for covering the tube. The shape memory alloy is enclosed by the cover of high corrosion-resistant stainless steel, by which high-temperature water can be prevented from making the shape memory alloy brittle and from corroding and damaging the shape memory alloy particularly through galvanic corrosion even in the case where such high-temperature water exists in the inside or outside of the pipes.
摘要:
New low-alloy steel compositions and rotor shafts for electric machines made from them are described. High nickel and chromium contents ensure high strength and toughness, while other components, notably silicon and other impurities, are kept low with the result that magnetic properties remain good. One aspect provides a steel with the following proportions by weight:C 0.15 to 0.3%Si 2%,

摘要:
An electrostatic coating system includes a coating robot (1) and an electrostatic atomizer (6) attached to a polyarticular wrist portion (5) of the robot (1). The atomizer (6) includes an end plate (45), metallic connector (50) fixed to the end plate (45) in electric conduction, high voltage generator (20) and bell head (18). Electric power is supplied to the high voltage generator (20) through the connector (50). Wires (53) are connected to the connector (50) to take out high voltage leak caused by contamination like a deposition of paint on outer surfaces of the atomizer (6) through the wires 53 to control the high voltage generator (20) to lower the value of the high voltage applied to the bell head (18) of high voltage leak detected through the wires (53) is larger than a predetermined threshold value.
摘要:
A painting material charging device may comprise a cartridge attaching unit, a painting material supplying path, a first switching unit, a painting material supplying unit, a discharging path, a second switching unit, a painting material sensor and a controlling unit. The controlling unit may be configured to be connected to the painting material sensor and the second switching unit. The controlling unit may be configured to cause the second switching unit to fully close the discharging path in a case where the painting material sensor detects the painting material.
