Title: High-level radioactive waste liquid tank
Inventor: HAYASHI KATSUMI
IPC: G21F9/22
Filed: 1990-08-22
Abstract: PURPOSE:To prevent sludge fixing to cooling piping and to contrive to improve reliability of heat removal performance by attaching cooling fins and the like necessary for heat removal to the surface of a tank and removing heat from the outside surface. CONSTITUTION:Cooling fins 4 are attached to a high-level waste liquid tank 1 sunk in a pool 5. In order to remove heat transferred from the fins 4, the heat of pool water is removed through a heat exchanger 6 with the use of a pump 7. In addition, supplementary feed water is fed from supplementary feed water piping 10 due to the evaporation and the like of the pool water. As a result, because cooling piping 8 is allowed not to flow through high- corrosive waste liquid, the cooling piping 8 is difficult to break and further, if the cooling piping 8 should be broken, the temperature thereof will not exceed a specified temperature because of the evaporation of the pool water. In addition, a quantity of water corresponding to evaporated water is fed into the pool 5 to control temperature increase thereof for a long time. Further, since there is no cooling piping 8 in the inside, it is easy to agitate and difficult for sludge fixing.

Abstract: PURPOSE: To relaize an excellent click feeling by pressing a position where the tip of a rule pin is dislocated from the rotational axis according to rotation of a key top, performing electrically continuing operation by pressing one electrically continuous domain by a contact point pushing part, and securing switching by a small switching stroke. CONSTITUTION: When a key top 1 is rotated to the window rising side (clockwise), a rule pin 3 in a neutral condition slidingly moves to the left side on a sliding contact surface 4C of a contact point action member 4 in response to an operation quantity of the key top 1 while compressing a spring 2. At this time, when an action force component applied to a contact point pushing part 4D from the spring 2 is smaller than resiliency possessed by a dome contact point 7A, the pin 3 slidingly moves to the left on the sliding contact surface 4C of the contact point action member 4 while compressing the spring 2. On the other hand, when compression of the spring 2 proceeds and the action component applied to the contact point pushing part 4D exceeds resiliency possessed by the contact point 7A, the member 4 rotates in the anticlockwise direction with a support shaft 4B as the center.  As a result, the contact point 7A receives compression, and a recess is generated, and the contact point is closed, and is electrically continued. At this time, a reliable switching feeling is given to an operator by rotation of the member 4.
