Device manipulation apparatus and method

摘要

A first flat surface portion (17) of an upper mounting member (11) is made to be parallel with a second flat surface portion (18) of a lower mounting member (12) by, first, supporting the lower mounting member on a spherical cushion of air defined by a lower surface portion (20). The first surface portion (17) is next brought into contact with the second surface portion (18) which causes an adjustment in the position of lower mounting member (12) so as to make the surfaces (17) and (18) coplanar. The air supply to the lower mounting member is then reversed to apply a vacuum which draws the lower mounting member (12) into contact with the support member (22) so as to fix the second surface portion (18) in a parallel relationship to that of the first surface portion (17).
