Abstract: The invention relates to a computer tomograph having an X-ray measuring arrangement (4,5) and a longitudinally movable patient couch (1). The transverse-layer image is produced by rotating the measuring arrangement (4,5) in a plane lying perpendicular to the patient couch (1). To produce a summary picture, the patient is moved in the longitudinal direction with the measuring arrangement (4,5) stationary. In this arrangement, the X-ray tube is pulsed, using a detector array as the beam receiver (5) and the computer (8) stores the output signals of the beam receiver (5) corresponding to one image line for each X-ray pulse. The switching on of the X-ray tube (4) is synchronised by the ECG (Fig. 1). <IMAGE>

Abstract: In a transfer-type electromagnetic relay, movable contact studs are attached to both ends of a leaf spring (38) fixed onto an armature (39) for reducing the relay thickness. Leads (26, 27) for fixed contact studs are made of a soft magnetic material. Permanent magnets (46, 47) are placed transversely on the leads with poles of the same name brought nearer to the leads. When selectively magnetized by a coil (48) wound around a housing (21, 22), the armature is swung to carry out contact transfer with a high sensitivity. The relay is rendered self holding by the permanent magnet and the soft magnetic leads. Only one permanent magnet may be used for a current-holding relay. The leaf spring has transverse and longitudinal arms for insuring contact between the movable and fixed contact studs and connection of the movable contact studs to leads thereof.

IPC: G03F1/20

Abstract: iIn vacuum sputter cleaning and plating operations forming a patterned metallisation on a semiconductor wafer (12), an alignment problem is due to the different thermal expansion of a molybdenum shadow mask (8) used and of the silicon wafer (12). This problem is solved by anticipating this difference in thermal expansion and forming the apertures (10) in the mask (8) in a radially offset position with respect to the intended cleaning and deposition locations on the wafer (12) at room temperature. Maintaining the mask (8) and wafer (12) in a concentric position and raising them to the cleaning and deposition temperature, the differential expansion will bring the apertures (10) into perfect alignment with the intended deposition locations on the wafer (12). Even if the mask (8) and wafer (12) are not maintained in a mutually concentric position, the mask's (8) offset pattern will reduce the average misalignment and the maximum misalignment over all apertures (10) and predeposited wafer structures.

Abstract: A pneumatic tool for use on a robotic arm for applying adhesive tape around bundles of wire, cables and the like. Three hollow tubes (3,4,5) are disposed in line abreast and extend from a body (1) which includes a chamber (29) with an inlet port (14) to which pneumatic pressure or suction can be applied and two oppositely acting ball valves of which one is in communication with the central tube (3) and the other is in communication with the interior of the outer tubes (4,5), which are hollow but which have a respective lateral aperture (33,33a) on the side facing the central tube. On the application of suction, the central tube (3) can hold a length of adhesive tape and the tool can be advanced into contactwith the bundle of wires around which the tape is to be applied. On the application of pneumatic pressure, the central tube (3) releases the tape and the pressure applied to the interior of the outertubes (4,5) advances them forwardly, against the force of a return spring (41). Air jets issue from the lateral apertures in the tube to force the tape around the bundle of wires.

Abstract: Two rectifiers (U 1 , U 2 ) and two inverters (U 3 , U 4 ) are operated in a state in which they are connected in parallel by common transmission lines (DC , DC n ). These rectifiers and inverters are controlled by an independent control apparatus (CA 1 ...CA 4 ) respectively which can selectively apply either a constant current control or a constant voltage control. The control apparatus (CA 1 ...CA 4 ) of each converter (U 1 ...U 4 ) has bestowed thereon the reference value (I dp11 ...I dp42 ) of the current flowing through the particular converter and the reference value (E dp ) of the terminal voltage of the particular converter. A signal (ΔI d ) for lowering the current reference value is added to the control apparatus of one or all of the converters (U 1 , U 2 ) which are to be operated as the inverters. On the other hand, a signal (ΔE d ) for essentially rendering the terminal voltage of the converter smaller than the voltage reference value is added to the control apparatus of the converter which is to be operated as the converter for determining the voltage of a direct current system.
