ABSTRACT:
A variable d.c. source is connected to electrodes provided on the inner and outer surfaces of a hollow cylindrical body formed of piezoelectric ceramic through a switch to achieve dilations of the body by a variable applied voltage.
Leg members are fixed at both ends of said body member. Sliding members are further fixed on the lower surfaces of said leg members and are slidable on a base plate. Between said leg members and said base plate, d.c. sources are connected through switches to electrostatically fix the structure. The structure can be moved finely and stepwise in a predetermined direction by operating said switches.
