Abstract: A protruding portion (13), which has a central axis coincident with a rotational axis of a table (10), is formed at a center portion of a surface of the table (10). At the time of the surface processing, the table (10) is rotated under a state in which the processing target surface of the substrate (12) is supported horizontally at each of a plurality of parts on the table (10) spaced apart from a base end of the protruding portion (13) toward an outer peripheral end portion of the table (10) by a predetermined distance and at the same distance from a top end of the protruding portion (13). Then, a processing liquid is supplied toward the top end of the protruding portion (13). The processing liquid that has reached the processing target surface of each substrate (12) is then removed outside the table (10) by centrifugal force.

Abstract: A surgical knife having a body with a blade at one end is provided that has an attached, movable shield that can be moved between either one of two locked positions. The shield can be placed in one position in which it covers and protects the blade and in a second position where it forms a portion of the body for use of the knife.
