摘要： A radiator includes a heat radiation ceramic material. The heat radiation ceramic material includes a first metal oxide as a principal component, the first metal oxide being a metal oxide having a wurtzite crystal structure; and a second metal oxide as a metal oxide having an average emissivity higher than or equal to 70% in a wavelength range of 3 μm to 25 μm inclusive. At least one of a trivalent metal-doped metal oxide where some metal atoms of the first metal oxide are substituted with trivalent metal atoms and a monovalent metal-doped metal oxide where some metal atoms of the first metal oxide are substituted with monovalent metal atoms is included as the second metal oxide.

摘要： A thermosetting resin composition of the present disclosure includes an epoxy resin (1) containing a curing agent, and inorganic particles (2) having a rutile-type crystal structure and an average particle diameter of 500 nm or less. Further, a stator coil of the present disclosure includes a coil conductor (6), and an insulating layer (7) obtained by winding an insulating tape around the coil conductor (6), impregnating the insulating tape with the thermosetting resin composition, and molding the impregnated insulating tape by heating and pressurizing. In addition, a rotating electric machine of the present disclosure includes a stator core (4) having a slot (10), in which the stator coil (5) is accommodated. According to the present disclosure, it is possible to obtain a thermosetting resin composition capable of achieving improvement in machine life through suppression of partial discharge and miniaturization and high output of the machine through improvement of a dielectric-breakdown electric field property, a stator coil obtained through use of the thermosetting resin composition, and a rotating electric machine.

摘要： In a vacuum valve, as a heat dissipation structure thereof, a heat dissipation layer is provided to a part of the surface of each of a fixed conductor and a movable conductor which are a heat generation part, and a radiation heat absorption layer is provided to an insulation cylinder so as to be opposed to the heat dissipation layer. The heat dissipation layer and the radiation heat absorption layer are each formed from a ceramic having a high emissivity. Heat generated at the fixed conductor and the movable conductor is radiated by the heat dissipation layer, to be absorbed by the radiation heat absorption layer, and then radiated to the outside of the vacuum valve from the radiation heat absorption layer and a ceramic layer.
