Abstract: [Problem] In a conventional rotating electrical machine to perform starting and power generation, an inverter and a rotating electrical machine body are constructed to be separate bodies, and a three-phase harness is provided between the rotating electrical machine and the inverter, and by a voltage drop or loss in this portion, there have been limitations in the improvement of starting and power generation output, and efficiency at the time of same operating current (determined by thermal limitation of the inverter). [Means for Resolution] Since an inverter unit 22 is integrally attached to a rear bracket 44 and is integrally mounted on the end face of a rotating electrical machine 20 in an axial direction, harnesses to be connected can be made short, and reduction in weight of the harness and improvement in resistance to outer disturbance noise can be realized.

Abstract: An X-ray tube includes an electron gun in which a Wehnelt electrode is formed with an opening asymmetric about an electron emitter. The electron emitter is an elongate coil filament which is disposed inside the elongate opening of the Wehnelt electrode. The opening has two longer sides positioned asymmetrically about a center-of-width line of the filament. Each of the two longer sides is curved in the same direction as viewed in a direction normal to the front face of the Wehnelt electrode. The two longer sides have curvature radii R1 and R2 different from each other, so that an electron-beam-irradiation region on a target is not curved but becomes almost straight.

Abstract: An output terminal mount includes a molded resin body in which a harness connecting portion and a mounting portion are formed integrally; internal terminals insert molded into the molded resin body such that connecting terminals at a first end are exposed inside harness slots and three-phase output wires are each connected at a second end; and three-phase output bolts insert molded into the molded resin body so as to project into each of the harness slots, nuts being fastened to the projecting portions such that the connecting terminals and terminals of a three-phase output wiring harness are placed in pressure contact with each other. The output terminal mount is mounted by fixing the mount portion to an end surface of a rear bracket at a position between an outer periphery of a crown portion and a radially outer peripheral surface of the rear bracket.

Abstract: A filament for an X-ray tube has a varied wire diameter but has a constant coil outside diameter to obtain a good uniformity of the longitudinal temperature distribution of the filament. The filament has a wire diameter d which is gradually reduced from the longitudinal central region to the longitudinal ends while the coil outside diameter D is fixed along the longitudinal direction. The wire is polished at only the inside of the coil to reduce the wire diameter. In order to make the longitudinal temperature distribution uniform as far as possible, the difference ?d between the wire diameter dmax at the longitudinal central region and the wire diameter dmin at the longitudinal ends should satisfy the following limitation: ?d/dmax=0.041 to 0.145.

Abstract: A coiled filament for an X-ray tube has a varied coil pitch to obtain a good uniformity of the longitudinal temperature distribution. The filament has a central region including plural turns having a same coil pitch, and end regions which include plural turns each of which has a coil pitch smaller than the coil pitch of the central region. The coil pitches of the plural turns of the end regions are reduced one by one by a same variation from a turn close to the central region toward an outermost turn. A value of ?p/p is within a range of 0.015 to 0.1 and k/n is within a range of 0.3 to 0.8, where p is the coil pitch of the central region, ?p is the coil pitch variation of the end regions, n is a total number of turns of the filament, and k is a sum of numbers of turns of the end regions. The k/n preferably satisfies the following equation: k/n=0.72?4.66(?p/p)±0.12.

Abstract: An X-ray diffraction apparatus allows plural kinds of characteristic X-rays to be incident on a sample at the same time and thus allows X-ray diffraction measurement with the plural kinds of characteristic X-rays to be carried out at the same time. An X-ray tube includes an anode which has the first target region made of Co and the second target region made of Cu. The first and second target regions are sectioned in a direction (Z-direction) perpendicular to an X-ray take-off direction. Incident-side and receiving-side Z-direction-divergence restriction devices restrict the X-ray divergence in the Z-direction. An X-ray detector is position sensitive at least in the Z-direction and can detect separately a diffracted X-ray coming from the first sample region which is irradiated with the Co characteristic X-ray and another diffracted X-ray coming from the second sample region which is irradiated with the Cu characteristic X-ray.

Permanent magnets are disposed between adjacent claw-shaped magnetic poles.

Abstract: A rotary current-collecting device includes a rotary slip ring and brushes coming into sliding contact with the outer peripheral surface of the slip ring. The brush-holding ring has an inner surface to which three brush-holding springs are fixed by screws. Each of the brushes is fixed to the tip end of the brush-holding spring and is pushed against the outer surface of the slip ring under the resilient restoration force of the brush-holding spring. When the slip ring revolves, the brushes come into sliding contact with the outer peripheral surface of the slip ring. The brush is made of a metal-graphite compound consisting of 70 weight percent copper and 30 weight percent graphite. The slip ring is entirely made of glassy carbon, so that the brush abrasion can be reduced.
