    摘要: Laser-induced color printing with means with which the printing color of a micro-capsule to be impinged by the laser beam (12) is identified. These means are a fluorescence transformer material as a constituent of the content of the micro-capsules (3) or an additional white light ray with which the printing color of an individual micro-capsule (3) can likewise be identified.The printing ensues given coincidence of a printing instruction provided for a defined location with color specification and of the momentary incidence of the scanning laser beam (12) on a micro-capsule (3) for which this printing color has been identified as being present.

    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.
