Abstract: PURPOSE:To miniaturize a sensor by fixing thin soft magnetic strips onto a torque transmission shaft in such a manner that the uniaxial anisotropic directions thereof attain alpha deg.(alpha>0) and -alpha deg. angle with said shaft. CONSTITUTION:An amorphous iron alloy 2a which is inclined by +alpha deg. in the longitudinal direction of the torque transmission shaft 1 and has a stress magnetic effect is fixed onto the circumference of the transmission shaft 1 by an adhesive agent. An amorphous alloy 2b which is similarly inclined by -alpha deg.is fixed thereto. Coils 3a, 3b are concentrically wound and formed on the outside of such alloys 2a, 2b and further, ferrites 4a, 4b which are soft magnetic materials are wound on the outside thereof so as to cover the coils 3a, 3b, respectively. A titanium plate which is a nonmagnetic material 5 adheres the ferrites 4a, 4b and provides large magnetic resistance between two torque detection units. The respective coils 3a, 3b are coupled to a differential detection circuit 6 so that torque can be detected from a difference in the inductance between the two coils 3a, 3b. A slender gap slit 8 is formed at the center of the amorphous alloys.

Title: Fuel element and method for improving heat transfer therein
Inventor: IRA NERUSON TEIRAA JIYUNIA
IPC: G21C3/18
Filed: 1993-10-25
Abstract: PURPOSE: To provide a novel bulkhead to be set between the metal fuel slug of a fuel element for liquid-metal cooled reactor and a fuel covering pipe. CONSTITUTION: A bulkhead is formed of a tubular bulkhead 18 having a noncircular cross section. At the result that such a bulkhead has the noncircular cross section, an improvement in thermal connection by liquid metal is attained in each critical surface area between the fuel covering pipe/the bulkhead and the bulkhead/a nuclear fuel. When the noncircular bulkhead is used, three contact sections containing a heat transfer cavity having an angle substantially equal to the heat transfer cavity seen in a metal fuel element containing no bulkhead are produced. Consequently, the circumferential non-bonding degree is lower than the level causing a local fusion of the nuclear fuel during irradiation.
