摘要： PURPOSE:To prevent the scattering of the welded unified sections of elbows, a nozzle and a mixer of a jet pump if it happens and obviate the damage of other reactor structures in a nuclear reactor pressure vessel by mounting a plate for preventing scattering to a notch section of a transition piece arm. CONSTITUTION:A plate 28 for preventing scattering is fitted to a notch section of a transition piece arm 27, and fixed to the transition piece arm 27 by a beam 20 by clamping a beam bolt 21. The plate 28 for preventing scattering can prevent scattering because elbows 13 reduce force functioning in the direction reverse to the ejecting direction of a jet pump. Thus, the mounting of the plate 28 for preventing scattering obviates the dispersion of the welded unified sections of the elbows 13, the nozzle 14 and the mixer 15 of the jet pump if the dispersion happens, and can avert the damage of other reactor structures installed into a unclear reactor pressure vessel.

摘要： PURPOSE:To obtain a rotary anode X-ray tube with long life by arranging a heat-resisting metal plate, which has a wing-shaped projection separated from the target surface while being fixed to the tip of a rotary axis together with the target at the central part, on the opposite side to the cathode of the target and sticking getter substance on it. CONSTITUTION:A heat-resisting metal plate 5, which has a wind-shaped-rojection separated from the back of the target while being fixed to the tip of the rotary axis extended from the anode rotary body 4 together with the target 3 at the central part, is arranged on the opposite side to the cathode 2 of the target 3. A getter substance 6 of so-called bulk getter kind such as zirconium or the like is arranged to stick to the back of said wing-shaped projection, for making it to perform a getter action. Thereby, on the gas gradually emitted from the target 3 and others having reached a high temperature due to load, the getter having similarly reached a high temperature actively perform a getter action so as to maintain always high vacuum inside an X-ray tube for contributing to a long life of the X-ray tube.

摘要： PURPOSE:To enable to readily match the dimensions of units of a motor to the needs of a machine which mounts the motor by providing cut and erected parts at a steel plate base and elastically supporting a housing for the motor by the elasticity of the erected parts. CONSTITUTION:A plurality of cut and erected parts 3 are formed laterally symmetrically on the bottom of a steel plate base 1 which is formed by pressing and molding resin. Extruded parts 4 are respectively formed at the ends of the parts 3. On the other hand, grooves are formed at the positions corresponding to the parts 3 of the base 1 at the steel plate housing of a motor. The extruded parts 4 of the parts 3 are press-fitted or engaged fixedly, thereby securing the housing to the base 1.

摘要： PURPOSE:To enhance the grade of concentration and to reduce the vibration and noise of an electric rotary machine when a hole is to be provided in a rotating shaft to insert a heat pipe thereinto and to be fixed by a method wherein the blockading end part of the hole is formed to have a taper type, and the spherical tip part of the heat pipe is adhered with pressure thereto. CONSTITUTION:When a long hole 13 is to be provided inside of a rotor shaft 1 to insert the heat pipe 7 therein to be fixed, the conical taper part 13c is formed at the end part on the blockade side of the long hole 13. Moreover the tip parts 7A2, 7A3 of the heat pipe 7 are formed to have the spherical face type, and the end 7A3 on one side thereof is adhered with pressure to the taper part 13c of the long hole. A cement 14 is poured into the gap between the heat pipe 7 and the long hole 13 to be fixed. Accordingly because the grade of concentration between the long hole 13 and the heat pipe 7 can be enhanced, unbalance can be eliminated, and vibration and noise can be reduced sharply.
