Abstract: A stator coil is configured of a first group of six turns of conductive wire, and a second group also of six turns, with the first group of six turns being wound on a spool, leaving a gap the same as the diameter of the conductive wire between winds. Upon completion of winding the first group, the winding is turned back, and the second group of six turns is wound in the gap, so as to be adjacent to the turns of the first group. The article is then inserted into a slot in a stator core of a stator, thereby configuring a stator coil. This provides for a rotating electrical machine and manufacturing method thereof with improved insulation resistivity regarding inverter surge voltage, and moreover high output can be obtained with a machine of comparable external dimensions with conventional machines.

Abstract: A gradient coil apparatus for magnetic resonance imaging system includes a plurality of gradient coils 11a, 11b and 11c for applying a gradient magnetic field to a test object and an internal heat exchanger 14 to be immersed in insulation oil 13 in a container 12. A pump 16 is disposed to circulate coolant between the internal heat exchanger 14 and an external heat exchanger 15 is disposed outside of the container 12. This arrangement allows the insulation oil only inside of the container, thereby ensuring a substantial reduction in the amount of insulation oil.

Abstract: An insulator of an electron beam generator is placed in vacuum, and will be electrically charged upon bombardment of electrons on the surface thereof, whereby a high electrical field is generated. In addition, when fine impurity particles are present on the surface of the insulator, such fine particles will move due to electrostatic force. These could be a cause of electrical discharge, resulting in an unstable accelerating voltage of an electron beam. An electron beam generator is provided in which an electron beam is generated from a cathode upon application of a voltage across the cathode and an anode. An insulator placed in vacuum has a ceramic substrate and a low-resistivity film formed on the surface of the substrate. The electrical volume resistivity of the low-resistivity film is less than or equal to one-hundredth of that of the substrate (see FIG. 2).

Abstract: In a charged particle accelerator, voltage of several tens of kV is applied between accelerating electrodes. In such a case, electric discharge is sometimes generated between the accelerating electrodes. In the charged particle accelerator, part or entirety of the accelerating electrodes is coated with an electric discharge suppressing layer made of ceramics or alloy having a high melting point as compared with metal. When impurity fine particles are accelerated by an electric field and collide with the electrodes, the electric discharge suppressing layer made of ceramics or alloy prevents metal vapor from being easily generated from the electrodes and an ionized plasma from being easily produced, thus suppressing electric discharge between the electrodes.
