である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring containing a shape memory alloy, which changes its shape by heating, a protective suit for protecting against radioactive contamination using the ring, and radioactive contamination by an operator from a non-contaminated area in the protective suit. The present invention relates to an operator's entrance / exit mechanism including the ring for entering / exiting without causing.

When working with protective clothing, the outside of the protective clothing is radioactively contaminated, so it is necessary to remove the contamination when moving to non-contaminated areas. However, removal of this contamination requires a lot of work. In Japanese Examined Patent Publication No. 7-95113, only workers can safely enter and leave between the contaminated area and the non-contaminated area while wearing the protective clothing and not between the contaminated area and the uncontaminated area. An entrance / exit mechanism that enables this is proposed. In this mechanism, since the screw is used to attach and detach the lid to the entrance opening of the side wall that separates the contaminated area and the non-contaminated area, the operation of attaching and detaching the lid is troublesome, There was a problem that skill was required for operation.

One example of that ring is shown in FIG. In this figure, R indicates a ring, a part of which is cut away. The size of the notch varies depending on the shape memory alloy or the like used, but may be appropriately determined according to the expansion or contraction of the radius of curvature of the ring generated when the ring is heated.
