    摘要: This invention provides a method for separating and enriching isotopes in an efficient and low-cost manner from a condensation-system (liquid or/and solid) material comprising two or more different isotopes by taking advantage of the sedimentation of atoms through an acceleration field by ultra-high speed rotation. A condensation-system (liquid or/and solid) material (5) comprising the two or more isotopes is placed in a sedimentation tank (for example, 2) which is then housed in a supercentrifuge. The supercentrifuge in its rotor is rotation driven by an ultra-high speed rotation power source, and an acceleration field of energy of 100000 G to 1500000 G, i.e., about 100 to 800 m/s in terms of peripheral velocity, is applied to the above condensed (liquid or/and solid) material under such a temperature that is specified by an isotope material to be enriched. In this case, a difference in centrifugal force applied is provided between the isotopes in the condensed (liquid or/and solid) material comprising the at least two isotopes. By virtue of sedimentation by taking advantage of this difference, isotope atoms within the condensed material interact, and, consequently, separation and enrichment of the isotopes can be realized in a higher efficiency than the case where gas is used, by conducting the separation and enrichment of the isotopes within the liquid material, using an effective material, and using a multistaged rotor system.

    摘要: An object of the present invention is to achieve more high-speed rotation of a rotor to which a test object is stored, extending the duration of high-speed rotation, and temperature control of a rotor at the time of high-speed rotation. A high-speed rotation testing apparatus of the present invention comprises: a rotor having a hollow for a test object, to which a predetermined test object is stored; a spindle connected to the rotor; a torque applying device for applying a predetermined torque to the spindle, and a casing for sealing the rotor. The casing comprises a decompressing device and a holder for holding the spindle. The holder has a bushing for supporting the spindle and a bushing supporting member for supporting the bushing by inserting thereto. By forming the inner diameter of at least one of the bushing supporting member larger than the outer diameter of the bushing, the bushing supporting member supports the bushing to be rotatable.

    摘要: A densified high performance rare earth-iron-nitrogen permanent magnet obtained from a powder of a Th.sub.2 Zn.sub.17 compound containing nitrogen at interlattice sites, without using autogeneous sintering and yet preventing decomposition and/or denitrification from occurring. The process for producing the same need not necessarily use a binder, and it comprises compaction molding, or charging while applying a magnetic field, a powder of a nitrogen intrusion T--R--N compound having a specified composition and a Th.sub.2 Zn.sub.17 crystal structure, and applying thereto shock compression at a drive pressure of from 10 to 25 GPa as reduced to an equivalent drive pressure in an iron capsule.
