Miniature linear motion actuator

(57) Summary straight line drive movement (20). The first mode of operation uses the single clamp technology made to expand slowly to a piezoelectric device by condition that the clamping force between this element and its base (38) holds a piezoelectric device in the regular position. Next it is made to contract very quickly, the inertia created by the action exceeds the above-mentioned clamping force, and a piezoelectric device (48) carries out relative displacement of the piezoelectric device to a base (38). The second mode of operation uses the double clamp technology in which the rear is clamped first, the front part is moved to the front, then the front part is clamped, and the rear is moved to the front. The semiconducting material which makes it possible to form a desirable very thin layer and small equipment is being used for all the case of the operation of these.
