  • 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.

  • Patent number: 10962921
    Abstract: An electrical connector of an image forming apparatus exposes outward from a bottom surface of the image forming apparatus. An electrical connector of a sheet feeder protrudes from a top surface of the sheet feeder. The sheet feeder has a slider configured to be horizontally movable, while holding the electrical connector of the sheet feeder, between a connecting position at which the electrical connectors of the sheet feeder and image forming apparatus are connected and a disconnecting position at which the electrical connectors are disconnected. A locking member having a locking engaged part is fixed to the image forming apparatus. When the slider is moved to the connecting position, a locking engaging part of the slider engages the locking engaged part of the locking member so that the locking member and the slider are locked such that they cannot be separated vertically from each other.
