The invention is directed to an unfailing pickup operation of an electronic component from a component storage portion at a seam of storage tapes connected even using a connection tape and prevention of reduction in a pickup rate of an electronic component. More particularly, it relates to a recombinant Lactococcus that can only survive in a medium, where well-defined medium compounds are present. Next, the strip beginning is placed against the lateral surface of a cylindrical matrix, whose cross section corresponds to the cross section of the box, with the aid of a patrix and attached by vacuum. The boil cooling device includes a first heat transmission member disposed in the server module enclosure, a second heat transmission member disposed outside the server module enclosure, and a plurality of pipes connecting them.
