摘要： There is provided an austenitic stainless steel which is corrosion-resistant in an environment of neutron irradiation, and can suppress stress corrosion cracking and embrittlement. At least one kind of additive selected from Ti more than 0.2 % by weight up to 0.6 %, Zr more than 0.2 % up to 1.14%, Hf more than 0.2% up to 2.24 %, V more than 0.2 % up to 0.64 %, Nb more than 0.5 % up to 1.17 % and Ta more than 0.5 % up to 2.27 % is added to austenitic stainless steel containing Cr, Ni and so on, and said at least one additive exists in a solid-solution state. Further, the steel has a wholly austenitic structure substantially free of carbide. In order to maintain the irradiation-induced segregation prevention effected by the addition element, the C content is limited to 0.01 to 0.008 %, and the N content is limited to 0.001 to 0.1 %. The irradiation-induced segregation of the constituent elements, such as Cr and Ni, occurring in a grain boundary under irradiation, and the deterioration of the corrosion resistance of the material, as well as the embrittlement, can be prevented.

摘要： PROBLEM TO BE SOLVED: To solve the following problem: when a conventional compact of dust magnetic core is used to construct a rotary electric machine, the strength of the compact is considerably low and there is a possibility that the iron core is broken in a manufacturing process for motors or when a motor is in actual use. SOLUTION: Low-viscosity resin is contained in a core of a dust magnetic core compact compression-molded and heat-treated and dried to enhance its strength. Specifically, a dust magnetic core compact is immersed in resin whose viscosity is reduced to 2.0 Pa s or so by diluting epoxy or unsaturated polyester resin varnish with thinner or the like. Since the dust magnetic core compact is a porous body, at this time, the following phenomenon is caused to occur by a capillary phenomenon: the resin enters several particle layers from the superficial cavity to the inside of the compact. With the resin left between particles, the resin sticking to the surface is wiped off or removed by a blower. Then the duct magnetic core is dried to enhance its strength.

摘要翻译：要解决的问题：为了解决以下问题：当使用粉尘磁芯的常规小型构造旋转电机时，压实体的强度相当低，并且铁芯有可能破裂在电动机的制造过程中或当电动机实际使用时。解决方案：将低粘度树脂包含在压缩和热处理和干燥以增强其强度的粉尘磁心芯的芯中。具体地说，将粉尘磁性核心压块浸入通过用稀释剂等稀释环氧树脂或不饱和聚酯树脂清漆而降低到2.0Pa·s左右的树脂中。由于尘埃磁性核心压块是多孔体，此时由毛细管现象引起以下现象：树脂从表层腔内到达压实体的内部进入几个颗粒层。在颗粒之间留下树脂时，粘附在表面上的树脂被吹扫除去或去除。然后将管道磁芯干燥以增强其强度。版权所有（C）2011，JPO＆INPIT
