    摘要： A shape-memory actuator device for maintaining an orientable member, in particular a solar generator (2), in a position aligned with the sun, comprises a distribution of lenses (12) for focusing the direct or indirect solar radiation (R) on a shape-memory element (13) as the position of the sun varies. The device further comprises a shielding member (14), which is connected in rotation to the orientable member (2) and is controlled by the shape-memory element (13) when the latter is activated following upon the heat generated by the solar radiation as far as a position in which it shields the lens (12) which is focusing the direct radiation (12). In said condition, the shape-memory element is de-activated, and the shielding member returns into a position in which it again uncovers the focusing lens (12). The shielding member thus continues to perform oscillations about the position aligned with the sun, following at the same time said position as the sun moves.

    摘要： A locking device for preventing the rotation and/or the axial movement of a pin (1) includes a coil spring (6) wound around at least a portion (1a) of the pin (1) and having one end (6a) rigidly connected to a support structure (2). In its undeformed condition, the spring has an internal diameter lower than the diameter of the pin (1), whereby in its resting condition the spring is tightened around the pin (1) to prevent a rotation thereof at least in a direction or an axial movement in any direction. The device includes shape memory means (4) for causing the unwinding of the turns of the spring (6) for the purpose of temporarily releasing the pin (1).

    摘要： A shape-memory actuator device to impart to a movable organ a sun-tracking movement, comprising a shape-memory element (9) that is progressively activated during the day. The progressive activation is obtained through optical means including an aligned series of convergent lenses (10) that cause beams of light to converge onto increasing portions of the shape-memory element (9) during the day, with the movement of the sun, so as to cause a progressive variation of one dimension of the shape-memory element that is transmitted to the driven organ.
