摘要： An impact producing actuator can vary energy to be applied to a shape memory alloy, depending on, for example, an ambient temperature. The impact producing actuator has a drive signal generation unit that generates a drive signal based on a single pulse signal generated in response to an input operation and outputs the drive signal, a switching element whose switching operation is controlled by the drive signal, and a shape memory alloy through which electric current passes for a period of time during which the switching element is turned on or off. The impact producing actuator is configured such that the period of time during which the switching element is turned on or off varies depending on the ambient temperature.

摘要： A drive device is provided which employs a shape memory alloy member, reduces load to the shape memory alloy member, has an outstanding initial operation performance, and can implement a movable member and an object to be driven without any gap therebetween. The drive device includes: a base member having, on a surface, an operation base part made up of one or more operation recesses; and a movable member disposed to be opposed to the base member and having, on the opposing surface, operation projections to be inserted into the operation recesses. The shape memory alloy member is interposed between the base member and the movable member, and the movable member is moved so as to be separated away from the base member in response to the contraction of the shape memory alloy member when energized. The drive device includes a spring which is supported by the base member and bias the movable member so as to be separated away from the base member.

摘要： A drive unit 1 includes a base member 3 having an operation base 32 having operation recesses 31, 31, ... in a front surface, a movable member 4 that is disposed to be opposite to the base member 3 and has operation projections 41 to be inserted into the operation recesses 31 in an opposed surface, and a shape memory alloy member 2 that is disposed between the base member 3 and the movable member 4 and shrinks by heat generated by passing an electric current. In conjunction with the shrinkage of the shape memory alloy member 2 by the passage of the electric current, the movable member 4 is moved in a direction away from the base member 3. The base member 3 has a fixed portion in its middle in a core axial direction of the shape memory alloy member, to fix the middle on a support member A.
