Abstract: A de-mating apparatus includes a first component, a second component and a pair of parallel linear bearings. The first component includes a first pair of arms, each of the first pair of arms including a first lift surface. The second component includes a second pair of arms, each of the second pair of arms including a second lift surface. The second lift surfaces are parallel to the first lift surfaces. The linear bearings connect the first component to the second component such that the first pair of arms may move perpendicularly to the first lift surfaces between at least a first position adjacent to the second pair of arms and a second position apart from the second pair of arms to de-mate an electrical connector assembly. A bearing plane defined by the pair of linear bearings does not intersect the first pair of arms.

Abstract: For providing an anti-bacteria which is made from a natural material, therefore harmless if it is absorbed in the human body, can be produced in mass production with low cost, and shows a high anti-bacteria effect, the anti-bacteria agent is obtained by heating a shell in an atmosphere of inactive gas and burning the shell under the temperature which finally reaches 700° C.-2,500° C.
