A stator for an electric rotating machine includes a hollow cylindrical stator core, a stator coil, an outer cylinder, and at least one restraint. The stator core is comprised of a plurality of stator core segments that are arranged in the circumferential direction of the stator core to adjoin one another in the circumferential direction. The stator coil is mounted on the stator core. The outer cylinder is fitted on the radially outer surfaces of the stator core segments so as to fasten the stator core segments together. The restraint is arranged on an axial side of the stator core and retained by the outer cylinder so as to restrain axial deformation of the stator core segments due to the fastening force of the outer cylinder.

A radiographic image detecting apparatus and a radiographic image capturing system are provided. The radiographic image detecting apparatus includes a plurality of photoelectric conversion elements for generating electric charge by emission of radiation, a bias line through which a bias voltage is supplied to the photoelectric conversion elements, a power supply for applying the bias voltage to the photoelectric conversion elements through the bias line, a current detector for detecting a bias current flowing through the bias line, and a reading circuit including an amplifying circuit. The current detector includes a current mirror circuit connected between the bias line connected to the photoelectric conversion elements and the power supply.

A stator for an electric rotating machine is provided which is equipped with a stator coil. The stator coil has a plurality of in-slot portions arrayed within each of slots formed in a stator core in a radial direction of the stator core. Adjacent two of the in-slot portions disposed in each of the slots have radially-facing surfaces which extend in non-parallel to one another at least one of ends of the in-slot portions. The non-parallel orientation of the radially-facing surfaces avoids close contact between entire areas thereof when the in-slot portions move undesirably within the slot in the radial direction of the stator core. In other words, a gap is kept between the radially-facing surfaces and serves as a radiator to dissipate heat, as generated in the in-slot portions.

A stator for a dynamoelectric machine includes a stator core and a stator coil. The stator coil is made up of wave-shaped electric wires mounted on the stator core. Each of the electric wires has in-slot portions, each of which is received in one of slots of the stator core, and connecting portions each of which is located outside of the slots to connect one adjacent pair of the in-slot portions. Each of the connecting portions includes an apex part that is located axially furthest in the connecting portion from the stator core and includes an oblique section extending obliquely with respect to the radial direction of the stator core. Further, the oblique sections of the electric wires on one side of the stator core in the axial direction of the stator core are oblique in the same direction as those on the other side of the stator core.

During sending the combined body 47 to the core member 6, the pre-orientation members 81 are respectively inserted into a plurality of the consecutive clearances 472 of a plurality of the clearances 472 formed between the adjacent straight overlap sections 471 of the combined body 47. By the pre-orientation members 81, the overlap of the straight portions 431 in the straight overlap section 471 and the pitch between the straight overlap sections 471 are aligned in advance.

A stator for an electric rotating machine includes a stator coil that is formed of a plurality of electric wire segments each of which is comprised of an electric conductor and an insulating coat covering the electric conductor. The electric wire segments include a joined pair of first and second electric wire segments. Each of the first and second electric wire segments has an end portion of a first predetermined length where the electric conductor is not covered by the insulating coat. The end portions of the first and second electric wire segments are joined together. For each of the first and second electric wire segments, the insulating coat has, at its boundary with the end portion of the electric wire segment, a peeled portion of a second predetermined length which has a distal end peeled from the electric conductor and a proximal end remaining attached to the electric conductor.

There is disclosed a method of manufacturing a stator for a dynamoelectric machine. The method includes a step of mounting a hollow cylindrical electric wire assembly, which includes a plurality of straight stacked portions of shaped electric wires, to a hollow cylindrical stator core that includes a plurality of slots formed in the radially inner surface thereof. The mounting step includes: (1) placing the electric wire assembly radially inside of the stator core so that each of the straight stacked portions of the electric wire assembly is radially aligned with a corresponding one of the slots of the stator core; and (2) radially expanding the electric wire assembly to insert the straight stacked portions of the electric wire assembly into the corresponding slots of the stator core.
