  • Patent number: 11154897
    Abstract: A piston includes: a base body; a sealing ring provided at an outer peripheral surface of the base body and configured to slidingly contact an inner peripheral surface of a container; a pressing body provided at one side of the base body in a non-hermetical state with respect to the container, the one side being close to a fluid; and a supporting member supporting the pressing body in a state where the pressing body is separated from the base body. The base body includes an air discharge hole through which an inside and outside of the container communicate with each other, the inside and outside of the container being sealed by the sealing ring. The pressing body can approach and separate from the base body between a first position at which the pressing body opens the air discharge hole and a second position at which the pressing body closes the air discharge hole.

  • Publication number: 20210317557
    Abstract: The present invention provides a highly fracture resistant, fatigue resistant copper-based alloy material and the like for which, for example, even when the material is subjected to repeated deformation consisting of loading of stress for applying a shape-memory alloy-specific strain and unloading of same followed return to the original shape, the alloy material is not susceptible to persistence of such strain. This copper-based alloy material has a multiphase structure in which a B2-type crystal structure precipitated phase is dispersed in a ?-phase-comprising matrix.

  • Patent number: 11114210
    Abstract: A control rod operation generates a rod insertion block signal during operation of a reactor. Four neutron detector assemblies including a plurality of LPRMs arranged in an axial direction of a core are arranged adjacent to a plurality of insertion selection control rods, respectively, which are simultaneously inserted into the core. Neutron flux ratio calculation units are arranged in each of the neutron detector assemblies, and ratios (neutron flux ratios BA/AA, CA/AA, and DA/AA) of an average LPRM signal of the respective LPRMs at positions B, C, and D to an average LPRM signal of the respective LPRMs at a position A which is closest to the control rod insertion end of the core are calculated. When the largest neutron flux ratio out of the neutron flux ratios exceeds a set neutron flux ratio, a rod insertion block signal which is generated by a local range rod insertion monitor is output.
