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： A mirror device for a camera. The mirror device includes a main mirror that directs luminous flux entering the photographic optical path of the camera to a position outside of the photographic optical path. A sub-mirror directs luminous flux passing through a half-mirror forming part of the main mirror to a rangefinding optical unit. The main mirror and the sub-mirror are retractable to outside the photographic optical path. A sub-mirror holder holds the sub-mirror, and is supported by a body of the mirror device so as to be retractable.

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.

摘要： A dc motor wherein a driving force thereof can be used effectively with a simple and compact mechanical construction and a motor controlling system which can control such a dc motor to be driven efficiently. The motor comprises at least two coils, and change-over means for changing electric connection of the coils to change over the motor, when power is selectively supplied to the coils, between a first mode in which the torque produced is relatively high and the rotational frequency is relatively low and a second mode in which the torque is relatively low and the rotational frequency is relatively high. The motor controlling system includes selecting means for automatically selecting one of the first and second modes to control the change-over means in response to a given condition of the motor.
