Sensorbaugruppe mit einem an einer wand montierbaren gehäuse

Abstract: Der Drucksensor (6) einer Drucksensorbaugruppe ist durch einen Durchgangskanal (22) eines Dichtkissens (20) und einen dichtend durch eine Trennwand (28) hindurchgefuhrten Rohrstutzen (54) mit dem Feuchtraum (32) in einer Fahrzeugture verbunden. Das Gehause (2) der Sensorbaugruppe befindet sich im Trockenraum (30). Sowohl das Innere des Gehauses (2) als auch der Trockenraum (30) sind gegenuber dem Inneren des Rohrstutzens abgedichtet, so das an die Wasserdichtigkeit des Gehauses (2), in dem eine Leiterplatte (4) und elektronische Komponenten aufgenommen sind, geringe Anforderungen gestellt sind.

Influence of annealing on depth distributions and microstructure of ion-implanted Ti6Al4V

Abstract: Ti6Al4V alloy was ion implanted with carbon, nitrogen, platinum, or gold. The effect of heat treatment at 500°C on the depth distributions of oxygen and implanted atoms was investigated using backscattering spectrometry. The phases in the near-surface region were determined using transmission electron microscopy (TEM) and X-ray diffraction (XRD). Platinum and gold are enriched in both α- and β-titanium solid solutions. Implanted carbon forms titanium carbide at lower concentration than nitrogen forms titanium nitride. The depth profiles of Au, Pt, and N are not altered by annealing. Implanted carbon as well as oxygen diffuse to larger depth upon heat treatment. Noble metal-implanted layers are permeable to oxygen diffusion. At concentrations exceeding 35 at. pct, implanted carbon and nitrogen act as a diffusion barrier for oxygen.

Electronic apparatus, e.g. for use in motor vehicles, is produced by supplying a circuit board with components, followed by a one-piece plastic molding

Abstract: A process for producing an electronic apparatus comprises supplying a circuit board (11) with components (111). The circuit board is then provided with a molded, one-piece plastic housing (12).
