    • Apparatus for retrieving images of microfilms on sheet-like microforms on which the microfilms form frames arranged in vertical and horizontal rows and including larger and smaller frames. A transporting unit can move a microform up or down in a vertical plane so as to place a selected horizontal row of frames in front of a horizontal light source. A carriage in front of the transporting unit supports two lenses which are in line with the light source and respectively serve to project the images of larger and smaller frames onto the screen of a television camera. The carriage is movable horizontally to place a selected lens into register with a selected frame of that horizontal row of frames which is located in front of the light source, and the carriage can transmit motion to a plate- or belt-like diaphragm which is disposed between the transporting unit and the lenses and has one or more apertures registering with that lens which projects the image of a selected frame onto the screen. The device for moving the carriage includes a steel band connected to the carriage and having encoded information which is scanned by one of two photoelectric detectors. These detectors are actuatable alternatively and are respectively associated with the lenses for the projection of images of larger and smaller microfilm frames to arrest the motor for the band when the corresponding lens registers with a selected frame.

    • An image is formed on a recording medium by illuminating a multitude of points on the surface of the recording medium to form lines of image points. Relative movement is effected between the recording medium and a plurality of light-emitting diodes. The light-emitting diodes are arranged in a plurality of rows. Each row extends parallel to the direction in which a line of image points to be formed upon the recording medium extends. The rows are arranged successively in the direction of relative movement. A plurality of projector lenses is operative for projecting reduced-scale images of the light emitted by the light-emitting elements of the plurality of rows onto a portion of the recording medium on which a single line of image points is to be formed. The projector lenses are arranged in a plurality of lens rows, each of which extends parallel to the direction of the line of image points to be formed. The lenses of each row project the light emitted by the elements of only a single respective one of the rows of light-emitting elements. Successive lenses within each lens row project onto the recording-medium line images of the light emitted by successive respective groups of the light-emitting elements of the associated row of light-emitting elements.

    • For the drive excitation, the method for the capacitive drive excitation of oscillators in sensors for the capacitive measurement of force, acceleration and, in particular, rotation rates according to the Coriolis principle, provides according to the invention for the use of high-frequency constant-amplitude pulse packets with no DC component, the width or phase angle of which can be adjusted in order to keep the oscillator speed constant, for the purpose of resetting or correcting tolerances. As an alternative, the method may also be configured in such a way that, in the case of oscillators with pairwise excitation electrodes which are symmetrical with respect to the rotation axis, equal constant-amplitude HF voltages are applied, the frequency of which is chosen to be substantially higher than the natural frequency of the oscillator, in which case a particular resulting force of attraction on the oscillator is brought about by shifting the phase angle between the drive voltages and, in the case of rotation rate sensors working according to the closed-loop principle, system resetting can also be ensured. By virtue of the invention, problems with coupling the excitation signal into the read channel of a micromechanical oscillator system can be brought well under control.

    • An image consisting of a multitude of image points is formed by effecting relative transport between a plurality of light-emitting diodes and a recording medium. The diodes are arranged in rows. The rows are arranged successively in the transport direction. The rows extend at an angle relative to the transport direction. The diodes of each single row are offset relative to those of the other row, in direction transverse to the transport direction, by an amount equal to the distance between adjoining diodes in a single row divided by the number of rows, and/or multiples of that amount. Each diode is provided with an optical unit which projects onto the recording medium a reduced image of the light emitted by the diode. The diode-control signals corresponding to a single line of image points of the image to be formed are applied to the individual diodes with different respective time delays dependent upon the rate of transport and corresponding to the different distances among the rows as measured in the transport direction.

    • Relative movement is effected between a recording medium and a row of light-emitting diodes (LED's). The row of LED's extends parallel to the direction in which the line of image points to be formed extends, and transverse to the direction of relative movement. Reduced-scale images of the LED's are projected onto the line on the recording medium on which the line of image points is to be formed. The LED's and/or the optical units forming the reduced-scale images are oscillated in a direction parallel to the direction in which the line of image points to be formed extends. Each image of an LED sweeps a straight linear region on the recording-medium line at least equal in length to the distance between adjoining LED's of the LED-row. During each n.sup.th half-period of oscillation, a succession of control signals is applied to each LED, determining a succession of adjoining image points which the respective LED forms upon the recording-medium line in question; n is an integer. The resultant line of image points contains a number of image points equal to an integral multiple of the number of LED's in the row of LED's.
