Abstract: A waterproof presskey structure includes a shell, a button or presskey, and an elastic element. The elastic element and the shell can be assembled together with gum, the presskey is movably assembled to the shell and matches with the elastic element. The elastic element comprises a tubular structure having an elastic wall. The elastic wall is arched, and the elastic wall projects out towards within the tubular structure. For the arched elastic wall stretches under pressure from the button or presskey, an assembly of the elastic element and other parts is not affected, the elastic element cannot be separated from the shell due to the gum failing, and water resistance between the presskey and the shell is increased.

Abstract: A method for improving resistance of a fusion reactor inner wall to plasma irradiation by using lamination structure comprises: making a material for facing plasma into multiple metal sheets, laminating the multiple metal sheets together according to a direction perpendicular to a wall surface, and combining the laminated multiple metal sheets with a copper substrate. The method relates to the field of nuclear applications, and is applicable to a plasma-facing surface on an inner wall of an apparatus for conducting a fusion reaction by using hydrogen isotopes. Not only does the method reduce aggregation of hydrogen, helium, and isotopes thereof, and the like, under a surface layer of a tungsten-based material, greatly reducing a blistering phenomenon on a surface thereof, but also reduces thermal fatigue cracking damages.

The link members form an array of geometric unit cells when the structure is expanded, and the height and the width of the structure when expanded are both greater than the height and the width of the structure when collapsed. In certain embodiments the structures have unit cells based upon triangles or bowtie shapes.
