摘要： A multiple exposure camera performing a plurality of exposures in one photographing operation has a diaphragm, a shutter and a controller. The diaphragm controls an amount of light passing through a taking optical system to reach a light receiving medium. The shutter controls an exposure time of the light receiving medium. The controller controls a degree of blur of a subject image formed on the light receiving medium by controlling an exposure operation at a predetermined aperture value and a predetermined shutter speed in each of the plurality of times of exposures.

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.

摘要： A camera has at least one motor, a spindle gear (i.e. a gear having a spindle) for rewinding and thrusting a film, a cam that rotates together with the spindle gear when the spindle gear is rotated in a film-rewinding direction and that remains at rest when the spindle gear is rotated in a film-thrusting direction, a direction-limiting mechanism for permitting the spindle gear to rotate in the film-rewinding direction only when the motor is rotating in a forward direction, and a transmission mechanism that comes into contact with the cam when the motor is rotating in a reverse direction and that, when the cam is in one of predetermined rotation positions, engages with and thereby transmits a driving force of the motor to a corresponding one of driven members provided one for each of the predetermined rotation positions. In this camera, paths for transmitting the driving force of the motor are switched by first rotating the spindle gear in the film-rewinding direction to bring the cam into one of the predetermined rotation positions and then reversing a rotation direction of the motor.

摘要： An ultrasonic drive apparatus for preventing a slip between an object to be driven and a driving part of the apparatus to drive the object. The driving part includes an elastic member through which vibrations from electrical-mechanical converters are transmitted to the object. The elastic member can deform in a direction in which the object is driven. The driving part makes a predetermined locus to drive the object while the elastic member deforms in the direction so as to absorb the slip between the object and the driving part. The elastic member and the converters are mounted symmetrically relative to an axis which is generally perpendicular to the direction in which the object is driven, so that the object can be driven forward and backward.
