Abstract: The drive has an electromagnet consisting of two or more symmetric magnetic yoke parts with limbs whose pole ends enclose an air gap. The hammer travels between the air gaps. Magnetic armature bridges are assigned, one to each air gap, and lie outside the gaps in the unexcited state and move into them in the excited state of the electromagnet. The excitation coil is wound on at least one yoke limb so that the greater number of its turns runs between two adjacent yoke limbs. Several adjacent yoke limbs (202-3etc.) of the same yoke part (202) or adjacent yoke parts run inside and/or outside the excitation coil (218). The yoke parts have a comb-like cross-section the hammer plane in the direction in which the hammer acts.

Abstract: The procedure relates to the row and/or column pick-up of electro-optical data. The electro-optical converter (1) consists of a matrix of piezo-electric, magneto-strictive or electro-strictive component elements fitted into a rectangular outer frame (5). The optical system is based on an object plane, with light beams passing through a lens system, which focusses the beam onto the converter plate (1). A scanning system is used to move a light spot along rows and columns, the movements causing electrical signals to be produced which may activate hydraulic, pneumatic or electromechanical elements.

Abstract: A solar collector having a lens array serving as a light incidence surface that focuses the light energy onto radiation passages in a coating located in the focal plane of the lens array, the coating having a radiation reflecting surface on the side away from the incident light and the radiation passages being enabled through energy that is locally effective through focusing of impinging light.

Abstract: X-ray fluorescence produced by a primary X-ray beam incident at a very flat angle (below 1 DEG ) onto the surface of a specimen contained in a vacuum chamber is used to analyze shallow layers and/or to determine depths of shallow surface layers, such as a very thin (typically between about 10A and 103A) silicon coating on Al or Cu layers which overlay a silicon substrate. Semiconductor profile determination may be another application of the invention.

Abstract: A technique for providing interconnections between pairs of contact points associated with a conductive line pattern by the use of an interconnection defining tool which is selectively alignable with respect to the conductive line. The conductive line pattern comprises at least one conductive line which is either continuous or shows interruptions, and from which lines branch off to the contact points. The tool is adapted to the conductive line and consists of a row of elements, the distance between which is dimensionally related to the distance between the branch-offs. After the tool has been adjusted to the conductive line in accordance with the respective connections, the elements of the tool are used for interrupting or connecting the conductive line at predetermined positions. If a radiation mask is used as a tool, the elements of the tool consist of areas which differ from their surroundings in their radiation transparency, and the conductive line pattern may exist as a latent image on a substrate covered by a photoresist layer sensitive to radiation. The invention serves to provide, in a circuit arrangement with redundant elements, a single circuit, the final wiring of which excludes one or several defective redundant circuit elements.

Abstract: An electromagnet consists of two essentially symmetrically designed magnetizable E-shaped yoke halves each embraced by a coil. The facing pole ends of the yoke halves form three aligned operating gaps. Between the operating gaps a tongue-shaped ram is arranged which is shiftable in the direction of the line of alignment of the operating gaps. The cross-section of the ram is adapted to the area of the operating gaps. The ram comprises cuboid-shaped armature bars of magnetizable material. The armature bars are geometrically designed in such a manner that their volume is on the order of magnitude of the operating gap volume. In the original position of the ram the armature bars are essentially positioned in front of the operating gaps of the electromagnet. Upon excitation of the electromagnet, the armature bars are pulled into its operating gaps, being accelerated in the process. The windings of the coils exciting the yoke halves are essentially positioned between the E-legs of the yoke halves. By transverse connecting means made of the same material as themselves, the armature bars may be connected to form a continuous part. In view of the operation of the actuator, these transverse connecting means do not have the same material thickness as the armature bars, that is, they take the form of narrow connecting strips between the armature bars.

Abstract: Bank for accommodating adjacent ram units. Each of these consists of a flat, narrow frame. A tongue-shaped ram, driven by an electromagnetic actuator, extends in a recess of the frame. For accommodating and guiding the individual print ram units, the bank is provided with a receiving bar and a comblike holding bar between which the frames are arranged. Extension pieces of the lower frame elements can be accommodated by slits in the receiving bar. The upper frame elements are held in recesses of the comblike holding bar. The tongue-shaped rams are laterally guided by the electromagnetic actuators which are arranged on both sides of the frame and are aligned to each other.
