Patent EP-0392151-A2 (EP)
Inventor: HALLER ANDREAS
IPC: H05K3/32
Filed: 1990-02-09
Abstract: The connection stamping foil consists essentially of an electrically conductive layer (1) which is provided by means of a separating layer (4') on a carrier strip (5). The electrically conductive layer (1) has an adhesive layer (2') on its side opposite the carrier strip (5). The adhesive and separating layers (2', 4') consist essentially of an adhesive (7'). Soldering powder particles (3') are dispersed in this adhesive material (7'). When such a connection stamping foil is subjected to pressure by means of a stamping die while being heated, the electrically conductive soldering powder particles (3') produce an electrically conductive connection with the substrate (6) or a conductor provided instead of the carrier strip (5) in the region of the stamping. Consequently, such a stamping foil can be used to produce electrical connections between conductor tracks and other electrical components in a single stamping process. <IMAGE>

Abstract: A valve arrangement for the simultaneous opening and closing of two separated supply pipes for liquid media having different characteristics, especially a different pressure. In each of the supply pipes (Z1, Z2) there is arranged a valve, which is operated by its own medium, is controlled by a magnetic armature (6a/b) and has a differential piston (2a/b), carrying the valve plate, on whose one side there is arranged a pressure chamber (3a/b) which is connected to the valve inlet flow, is connected via a valve seat (4a/b) to the valve outlet and on whose other side there is arranged a control chamber (5a/b) which is connected via a discharge hole (2.1a/b), which is arranged centrally in the differential piston (2a/b) and can be closed by a magnetic armature seal (6.1a/b) arranged on the magnetic armature (6a/b), to the valve outlet and via a control hole (2.2a/b), arranged eccentrically in the differential piston, to the pressure chamber (3a/b). The two valves are driven via a common magnet system (St). Said magnetic system has a magnetic coil (7) in whose coil axis there is arranged a guide tube (8a/b) in which the two magnetic armatures (6a, 6b) are guided such that they can move. When the common magnet system (St) is energised, the two magnetic armatures (6a/b) pull in simultaneously and the two valves open. <IMAGE>

Abstract: A method for simulating an analog display in a digital display spectrum analyzer (or other digital display test instrument) comprises the steps of defining a plurality, N, of traces of the signal to be displayed, assigning coordinate values to points along each trace, and plotting and simultaneously displaying each of the N traces by illuminating corresponding pixel locations on the CRT as indicated by the assigned coordinate values. The method permits effective simulation of trace persistence as commonly found in analog display test instruments. According to one embodiment of the invention, a color graphics controller/color CRT may be provided, in which case gray scales may be generated and displayed to simulate variations in intensity levels as commonly found in traces plotted on analog display test instruments. An apparatus for practicing the method is also disclosed.

Abstract: A magnetic resonance imaging method of fast contemporaneous aquisition of differently weighted plural images using sequences having cycles composed of a plurality of different sub-cycles or modes which interact to produce a steady state free precession spin ensemble. Each sub-cycle has an rf excitation pulse and gradient magnetic field variations in orthogonal directions. For each sub-cycle, the excitation pulse flip angle, the sub-cycle duration, and the vector gradient integral over the sub-cycle is the same in each cycle. The sub-cycles differ from each other in at least one of pulse angle, duration and gradient integral. The gradient waveforms are chosen so that the steady state free precession spin ensemble, when represented in k-space, has spaced-apart differently weighted image transform lobes, a plurality of which are scanned by k-space excursions in each sub-cycle exciting gradient echo signals which may be separately collected for each image transform lobe of interest.
