Abstract: © Method for connecting optical fibers comprising the steps of molding a first plug onto a first fiber end and a second plug onto a second fiber end, said plugs having three mutually intersecting flat surfaces, one of which is perpendicular to the other two, while a fiber end is positioned against the corner in an orientation such that the end of the fiber butts against said one corner surface and the side surface of the fiber tangentially touches said other two corner surfaces and aligning two such plugs (44, 46), each carrying a fiber end, with each other in an alignment frame (76) having two flat alignment surfaces (22, 24) which are oriented with respect to each other at the same orientation as the two corner surfaces which tangentially touch the fiber side surface. Since these orientations are the same, the plugs fit precisely into the groove formed by the two flat alignment surfaces of the frame and can be moved toward each other until they touch. In this position the fiber ends carried by the castings are butt aligned.

Abstract: Es werden wäßrige Fluorpolymeren-Dispersionen, enthaltend kolloidale Teilchen eines teilweise modifizierten Tetrafluorethylen-Polymerisats, die daraus durch Koagulation gewonnenen Fluorpolymeren-Harzpulver sowie ein Verfahren zur Herstellung der genannten Dispersionen beschrieben. Die Teilchen besitzen einen dreischaligen Teilchenaufbau, wobei der Teilchenkern und die äußere Teilchenhülle aus einem mit einem modifizierenden, fluorolefinischen Comonomeren versehenen Tetrafluorethylen-Polymerisat und die innere Teilchenhülle aus Tetrafluorethylen-Homopolymerisat besteht. Als modifizierende Comonomere dienen Fluorolefine Perfluorolefine, Halogenfluorolefine sowie ganz oder teilweise fluorierte Vinylether. Die Herstellung erfolgt nach der Saat-Technik oder Zwischenentspannungsmethode, wobei in der ersten Phase der modifizierte Kern gebildet wird und in der zweiten Phase in die laufende Tetrafluorethylen-Polymerisation das modifizierende Comonomere nacngeschleust wird. Die gewonnenen Harze eignen sich besonders für das Pastenextrusionsverfahren zur Herstellung von Kabelisolierungen und von hochreckbaren, ungesinterten Bändern, nach entsprechender Aufbereitung auch für die Ram-Extrusion und Preß-Sinter-Technik.

Abstract: For securing the wound coil wires, a depot material that can be baked should be added. According to the invention, for applying the bakable depot material, rather than using a special baking lacquer wire (winding wire with a baking lacquer coating applied to its circumference) or alternately providing a depot thread layer to be melted between the winding wire layers, a discrete, bakable depot thread is wound parallel at the same time winding-for-winding with a conventional lacquer-insulated winding wire; by this means, the coil winding can be secured by baking in a simple manner and virtually without any increase in the slot filling factor, since the discrete depot thread generally takes up the free filler spaces between adjacent winding wires of the wound coil winding. In particular, there is then no need for a separate compression moulding, provided the mechanical pressure is selected to be large enough by appropriate pretensioning of the winding wire on winding. An application is particularly suitable for stator windings of small motors wound in slots in laminate stacks. <IMAGE>

Abstract: According to the invention an electron beam pattern transfer device with an improved alignment means is provided. 
     A first and a second mark M,, M 2  for alignment purposes are formed on the surface of the wafer (26) and the wafer holder (27), respectively. The first mark M, is formed on the wafer by conventional lithographic technique and the second mark M 2  consists of a hole or a heavy metal, such as Ta or Ta 2 O 5 . A third alignment mark M 3  is provided on the photocathode mask having a position corresponding to M 2  on the wafer holder and spaced a known distance L 2  from an imaginary reference position M 4  on the mask. The first step of the alignment process requires the detection of a relative distance L, between the first and second marks M,, M 2  by conventional detecting means, such as an optical measuring means. In the next step, the relative position of the photocathode mask and the wafer holder is adjusted so that the distance between the marks M 2  and M 3  is made substantially equal to the difference between distance L, and the known distance L 2 .

Abstract: A technique for providing an ion beam variable focussing (concentration) is described using a flexible grid for extracting and accelerating ions from an ion plasma. The grid is electrically conducting and will bow depending on a voltage difference between it and the ion plasma. This bowing of the grid from its initial planar configuration provides focussing of the ion beam. The amount of focussing depends upon the amount the grid is bowed, which in turn depends upon the voltage difference between it and the ion plasma. The same ion source/flexible grid combination can be used for different operations as for example, providing a collimated, low energy ion beam over a large area and then for providing a focussed ion beam of high energy onto a small area. 
     Figure 1 shows a plasma chamber 18 having a flexible metallic grid 34 covering its exit aperture. lonisable gas enters the chamber 18 via inlet 22 and exits form the vessel 12 via outlet 26. Ions are formed in the chamber 18 and are drawn by grid 34 into collimated beams 32. As the voltage difference between the plasma 44 (Figure 2) in the chamber and grid increases the grid flexes into a part spherical shape and the ion beam becomes focussed.

Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung, die, an Apparaturen der Druck- und Vakuummeßtechnik empfindlichen Druckmeßzellen vorgeschaltet oder in sie integriert, das Vordringen aggressiver oder kondensierbarer Gase bzw. Dämpfe in das Innere der Meßzelle verhindern und im gasförmigen Meßmedium enthaltene Schmutzteilchen zurückhalten. Die Lösung besteht darin, daß ein niederfrequent schwingender Membran-Körper, der innerhalb eines druck- bzw. vakuumdichten Rohrgehäuses so angebracht ist, daß er zwar den lichten Rohr-Anschlußdurchmesser optisch versperrt, über einen oder mehrere Umwegbohrungen aber den statischen Druckausgleich ermöglicht, durch seine Bewegungsenergie direkt auftreffende Schmutzteilchen und Gas- oder Dampfmoleküle zur Änderung der ursprünglichen Bewegungsrichtung zwingt. Die Erfindung ist anwendbar sowohl im Druckbereich oberhalb des Atmosphärendruckes wie auch im Vakuum bis zu Absolutdrücken < 10 Pa. Sie ist einsetzbar als separates Bauteil, wie sie auch in Vakuummeßzellen, insbesondere Modulationsmeßzellen, integrierbar ist. Durch die Erfindung wird die kontinuierliche und lineare Messung des Gasdruckes über einen großen Meßbereich gewährleistet.
