Abstract
Because it is possible to cool down a column member at a higher speed than natural cooling, throughput can be improved further. Especially, when the tubular body Mand the column part Mare made of different metals and the column part Mis pressed into the tubular body Ma distortion will occur in the column member Mand Mand the top board Mfixed to the column member Mand Mdue to the difference in thermal expansion coefficients between them, but the cooling paths Pand Pcan absorb a distortion caused by the difference in thermal expansion coefficients of these metals. In particular, when the top board Mis used as a mold for resin molding, it is possible to perform resin molding precisely because distortion caused by the difference in thermal expansion coefficients does not easily occur.
