    摘要: PROBLEM TO BE SOLVED: To provide an actuator device that does not incur increase in size and is excellent in working speed.
    SOLUTION: The actuator device includes: an actuator unit that has multiple shape-memory materials and a biasing portion biasing the shape-memory materials against change in their shape and is actuated by change in the shape of the shape-memory materials; an application unit that energizes and heats the shape-memory materials; a detection unit that detects the physical property values of the shape-memory materials that vary with change in the shape of the shape-memory materials; and a computation unit that carries out arithmetic processing based on the physical property values detected by the detection unit. Based on the physical property values of each shape-memory material obtained at the detection unit, the amount of energization and heating of the remaining shape-memory materials is controlled.

    摘要: PROBLEM TO BE SOLVED: To provide a shape memory alloy actuator which can be thinned with a simple structure and which does not malfunction even if an environmental temperature rises.
    SOLUTION: The actuator is provided with a flexible sheet 21 having a movable part 21a supported by a non-movable part 21b; a first shape memory alloy wire 22 stitched to the movable part 21a with a seam width larger at a lower side than at an upper side; and a second shape memory alloy wire 23. The movable part 21a deforms due to contraction by resistance heating of first shape memory alloy wire 22, and is restored to an original state by adjusting an amount of power to be supplied to the wire 22. The second shape memory alloy wire 23 is stitched to the movable part 21a with a seam width larger at an upper side than at a lower side. When the environmental temperature rises to a transformation temperature or higher, a force acting on the movable part 21a due to contraction of the first shape memory alloy wire 22 is canceled by a force acting on the movable part 21a due to contraction of the second shape memory alloy wire 23, and thus, the movable part 21a is not deformed.

    摘要: PROBLEM TO BE SOLVED: To provide a lens driving mechanism employing an SMA (Shape Memory Alloy) actuator, which enables to obtain a large displacement amount, while reducing the size and the weight of the driving mechanism. SOLUTION: The lens driving mechanism includes a lens unit 10, a driving member 20 for moving the lens unit 10 in an optical axis AX direction, and the SMA actuator 30. The driving member 20 has a displacement output portion 20out which can be moved in the optical axis AX direction and displacement input portions 20in which receive the input of moving force in a direction orthogonal to the optical axis AX and move the displacement output portion 20out in the optical axis AX direction, and is engaged with a support part 12 of the lens unit 10 at the displacement output portion 20out. The SMA actuator 30 is stretched over guide pieces 211 projectingly provided in the displacement input portions 20in. Moving force orthogonal to the optical axis AX is input to the displacement input portions 20in by the thermal contraction of the SMA actuator 30. COPYRIGHT: (C)2008,JPO&INPIT
