Abstract
A microposition table is held in place by the friction between a series of plates contacting one another. Movement is effected by forcing a small burst of air through a series of channels to drive metal pistons each held captive inside an elongated cylinder. The impact of each piston striking one or the other of the cylinder ends imparts sharp mechanical impulses to each plate driving the plate a small distance in the direction of the impacting force. Repeated impacts by repeated bursts of air move the plates the desired distances with respect to one another.
