ABSTRACT:
A method for fine positioning a component through the use of fusible elements having two or more melting points so as to establish intermediate displacements between totally melted fusible elements and unmelted fusible elements. Because of the use of non-eutectic fusible materials, fine adjustments in the displacement may be achieved.
