摘要： A photographic or electronic camera is disclosed having an optoelectronic distance meter. Linear sensors are provided and by way of partial aperture diaphragms associated with a lens first and second images are created and projectd onto the image sensors. An evaluating circuit, in dependence upon varied position displacements of the sensor signals, determines a maximum correlation between the signals and an associated position displacement with a corresponding electrical value corresponding to distance. A stringing mirror deflects the path of rays either into the view finder or to an image plane for picture taking. The swinging mirror has apertures positioned to permit the first and second bundles of rays to pass therethrough. Deflection elements are attached to the swinging mirror and are positioned to direct the partial bundles of rays passing through the apertures such that the images are projected onto the image sensors.

摘要： Circuit arrangement for inducing oscillations in an ultrasonic transducer approximating its natural resonance frequency, and comprising an oscillator for generation of an excitation AC voltage. A pulse gate circuit is connected to supply pulse wise application of the AC voltage to the transducer. The oscillator frequency is controlled by an auxiliary pulse generator connected to the transducer in parallel with the oscillator. A gate circuit and a phase discriminator are employed to produce favorable excitation for the particular oscillation mode of the transducer. The transducer is made preferably from a piezo electric ceramic. The circuit includes means capable of automatically finding the resonance frequency of the transducer.

摘要： An electrically actuated positioning element system utilizes a positioning element formed of piezo-electrical bodies each formed of a plurality of lamellae having electrodes. The lamellae have a length substantially greater than their thickness and upon application of an electrical voltage with a field direction which promotes a polarization of the material of the lamellae, the body is shortened. The two bodies are connected to one another at one end by a cross arm and at the other end the one body end is active and free to move relative to the other body end such that a resultant relative motion occurring between the two body ends may be utilized. Preferably a connection is provided for absorbing a lateral thrust of the bodies. The two piezo-electrical bodies are each electrically connected to one another for reverse-phase operation such that one contracts while the other is in a lengthened condition and vice versa.
