Abstract: A method for manufacturing a rare-earth magnet, through hot deformation processing, having a high degree of orientation at the entire area thereof and high remanence, without increasing processing cost including a step of press-forming powder as a rare-earth magnetic material to form a compact S; and a step of performing hot deformation processing to the compact S, thus manufacturing the rare-earth magnet C. The hot deformation processing includes two steps of extruding and upsetting. The extruding is to place a compact S in a die Da, and apply pressure to the compact S? in a heated state with an extrusion punch PD so as to reduce the thickness for extrusion to prepare the rare-earth magnet intermediary body S? having a sheet form, and the upsetting is to apply pressure to the rare-earth magnet intermediary body S? in the thickness direction to reduce the thickness, thus manufacturing the rare-earth magnet C.

Abstract: Provided is a process for recovering metals from solid radioactive waste, preferably uranium, cesium, mercury, thorium, rare earths or combinations thereof. The process comprises a leaching step and a separation step. The leaching step comprises contacting the solid radioactive waste with an aqueous inorganic acid and a leaching salt to produce a mixture of a metal-rich leachate and a metal-poor waste, which are separated in the separation step. Also provided is a process for recovering metals from solid radioactive waste comprising an attrition step, a leaching step, a washing step, a combination step and a recovery step.

Abstract: A system for bundling a plurality of high temperature superconductor tapes into a flexible cable, includes a first alignment device for receiving and guiding there through the plurality of high temperature superconductor tapes, each of the tapes arranged with a wide surface oriented at a first angle. There is a second alignment device for receiving and guiding there through the plurality of high temperature superconductor tapes, each of said tapes arranged with the wide surface oriented at a second angle. The first angle is transverse to the second angle and plastically deforms the tapes to impart a twist pitch in the tapes. There is a forming member spaced from the second alignment device for receiving the plurality of high temperature superconductor tapes with the imparted twist pitch and forming them into a bundle of high temperature superconductor tapes of the high temperature superconductor tapes with the imparted twist pitch.

Abstract: A method of production of core/shell type nanoparticles includes the following steps: a first step of applying a first power to cause the generation of the plasma so as to selectively cause the precipitation of a first metal so as to form nanoparticles as cores and a second step of applying a second power which is larger than the first power to cause the generation of the plasma so as to cause the precipitation of a second metal which has a smaller oxidation reduction potential than the first metal on the core surface so as to form shells which are comprised of the second metal which cover the cores which are comprised of the first metal.

Abstract: A number of configurations of a high speed electromagnetic turbine (1300) are discussed. The turbine (1300) includes a housing (1301) includes at least superconducting coil (1307) for the generation of a magnetic field, the coil being retained within a cryogenic envelope of a cryogenic body (1306). The turbine (1300) includes also includes rotor assembly including one or more rotors (13091), (13092), (13093), (13094), (13095) and (13096) positioned on shaft (1310). The rotor being received within the bore (1308) formed between the interior walls of the body (1306) such that it is immersed in the magnetic field. As the current is passed through the rotor assembly the induced force due to the interaction of the current with the magnetic is translated into a torque on the shaft (1310).

Abstract: A method for producing a timepiece spring includes a step for producing, by casting, a metallic glass raw material constituted of a metallic glass; a step for heating the metallic glass raw material to achieve a superplastic state; and a step for rolling the metallic glass raw material in a superplastic state to produce a sheet material. A timepiece spring is characterized by being obtained by the method for producing a timepiece spring.
