摘要： Drive technology is provided which makes suitable low velocity driving and smooth changing of driving velocity possible and achieves reduced power consumption. In the driving device, the drive unit is driven which engages with drive shaft which moves back and forth in tandem with extension and contraction of the piezoelectric element. In this driving device, when the output cycle for cycle Te is repeated such that the voltages applied to the piezoelectric element 11 are the maximum value (+Vp), the minimum value (−Vp), and the middle value (0V), the movement velocity of the drive unit 13 can be changed by thinning the output cycle at cycle Tf. As a result, suitable low velocity driving can be carried out and power consumption can be reduced in the drive unit.

摘要： An actuator applied with shape memory alloy which can be operated in a wide operating temperature range and has a long life time. At a normal ambient temperature, when the first wire of the acting member made of shape memory alloy in which predetermined shape is memorized in advance, is heated, it is transformed to the memorized shape to enable the acting member to be moved. A relative low stress is generated at the first wire and its life-time is not shortened. In the case that the ambient temperature is increased to exceed a transformation starting temperature of the shape memory alloy, the second wire of shape memory alloy is transformed to the memorized shape to generate a high stress at the first wire and to increase the transformation starting temperature of the first wire. With such an arrangement as above, it is possible to operate the actuator applied with the shape memory alloy in a wide operating temperature range.

摘要： To provide an image shake correcting optical apparatus using a small, lightweight engaging mechanism for the correction lens holder engaging mechanism. A ring-shaped engaging member 16 formed of shape memory alloy and having three engaging arms on its inside is located outside a lens holder 11 for a correction lens L3, and the engaging contacts 16b at the tips of the engaging arms 16a are pushed toward the center of the ring-shaped engaging member by means of coil springs 17. The engaging member 16 formed of shape memory alloy has a prescribed memorized shape so that the arms 16a will assume a retracted position, and where no heat is applied, the engaging contacts 16b of the engaging arms press onto the lens holder 11 for the correction lens L3 from the outside due to the spring force of the coil springs 17, and engages with and maintains in place the lens holder 11. Where heat is applied, the engaging arms 16a retract, whereupon the engagement of the lens holder 11 is terminated.
