    摘要: A turbine rotor provided with a sealing member for preventing air leaks through a gap between the under side surface of a projection extending from one of discs of the rotor and the upper side surface of a outward end portion of the spacer interposed between the discs. The spacer is formed with an annular groove on the upper side surface of the outward end portion for receiving a sealing wire in its entirety. The sealing wire has its outer portion forced against the underside surface of the projection by centrifugal forces while its inner portion remains inside the groove during turbine operation, to thereby seal the gap to prevent leaks of air therethrough.

    摘要: A stepping motor having a rotor that includes a magnetic component whose circumferential part is magnetized in multipole along the circumferential surface thereof, the stepping motor being capable of forcing the rotor to rotate by magnetic force provided between magnetic poles of the rotor and excited salient poles of a stator, in which the magnetic component includes two magnetic component portions each shaped as an approximate ring, and the two magnetic component portions are either combined with each other or set up separately at an appropriate spacing between them. The stepping motor is capable of rotating with not only high speed but also less undesired vibration and noises, and enabling a simpler, smaller manufacturing equipment thereof to be constructed.

    摘要: A cobalt-base alloy comprises 0.2-1 wt % C 0.4-2 wt % Si, 0.2-1.5 wt % Mn, 5-15 wt % Ni, 20-35 wt % Cr, 3-15 wt % W, 0.003-0.1 wt % Ni, 20-35 wt % Cr, 3-15 wt % W, 0.003-0.1 wt % B, 0.05-1 wt % Nb, 0.01-1 wt % Ta, 2 wt % or less Fe, 30 ppm or less oxygen, 100 ppm or less nitrogen, and the balance of 45 wt % or more Co, wherein the content of Si is larger than that of Mn. The alloy is in a form of casting and has a structure containing a eutectic carbide and a secondary carbide dispersed therein. The cast alloy is produced through solution treatment at 1,100.degree.-1.200.degree. C., and aging treatment at 950.degree.-1,050.degree. C., and cooling rate after the solution treatment and after the aging treatment is 150.degree. to 300.degree. C./h. A gas turbine nozzle is made of a casting of the above-mentioned alloy.

    摘要: A motor has a sealed structure, in which a stator core is disposed outside rotors attached to a rotating shaft held by bearings. The motor is equipped with bushes for fixing the bearings, a housing having a through hole from which one end of the rotating shaft protrudes, and pushing spring shims disposed inside the housing for pushing the bush in the longitudinal direction of the rotating shaft. The housing includes a plate portion and a sealing case formed in the shape of a hollow cylinder with a bottom. The bushes have cutout portions formed for positioning the stator core and the rotors in the direction perpendicular to the rotating shaft and for positioning the rotors in the longitudinal direction of the rotating shaft, and the plate portion and the sealing case constituting the housing are sealed by a sealing material.
