  • Publication number: 20200099180
    Abstract: An L-shaped coaxial connector having a coaxial cable includes a coaxial cable including a central conductor portion and an external conductor portion disposed around the central conductor portion and a center conductor portion, an internal terminal connected to the central conductor portion, an external terminal connected to the external conductor portion, and an insulating member disposed between the internal and external terminals. The external terminal includes a cylindrical portion surrounding the first terminal portion and extending in a cylindrical shape in a direction intersecting an axial direction of the coaxial cable. The internal terminal includes a male type first terminal portion having a cylindrical shape and extending in the direction intersecting the axial direction, and a second terminal portion extending to connect from the first terminal portion to the central conductor portion.

  • Patent number: 5293411
    Abstract: Decreasing the speed of a pump supplying cooling water to the core in the boiling water type nuclear reactor based on a trip signal that is generated when a pump supplying feed water is tripped. This performs a first operation to decrease the nuclear reactor power to a first fixed value. A second operation lowers the nuclear reactor power to a second fixed value that is lower than the first fixed value and that prevents run-out of other first pumps in operation. The first fixed value is lower than the reactor power at the moment when the first pump is tripped. The steam flow is decreased substantially simultaneously with the decrease of the feed water flow. Thereby, the decrease of the steam flow is carried out in an early stage when the feed water pump is tripped and the possibility of nuclear reactor scram is reduced.
