Abstract:

This patent application discloses a device in which a plurality of drive modules positioned at spaced locations along a drive path of a driven member respectively include two magnetostrictive rod elements in alignment with each other, with adjacent ends thereof in engagement with a third magnetostrictive rod element extending transversely of the drive path to engage the driven member. Simultaneous elongation and contraction of the two rod elements during elongation of the third rod element in the drive modules imparts unidirectional motion to the driven member.
