Abstract: A plasma spray method for the manufacture of an ion conducting membrane, in particular of a hydrogen ion conducting membrane or of an oxygen ion conducting membrane. In the method, the membrane is deposited as a layer on a substrate in a process chamber, wherein a starting material is sprayed onto a surface of the substrate by means of a process gas in the form of a process beam. The starting material is injected into a plasma at a low process pressure which is at most 10000 Pa and is partially or completely melted there. In accordance with the invention, the substrate has pores which are connected amongst one another so that the substrate is gas permeable and a portion of an overall pore area of an overall area of the coating surface amounts to at least 30% or, in a particular embodiment, to at least 40%.

Abstract: A plasma spray method for the manufacture of an ion conducting membrane, in particular of a hydrogen ion conducting membrane or of an oxygen ion conducting membrane is suggested. In which method the membrane is deposited as a layer (11) on a substrate (10) in a process chamber, wherein a starting material (P) is sprayed onto a surface of the substrate (10) by means of a process gas (G) in the form of a process beam (2). The starting material is injected into a plasma at a low process pressure which is at most 10000 Pa and is partially or completely melted there. In accordance with the invention the substrate (10) has pores (30) which are connected amongst one another so that the substrate (10) is gas permeable and a portion of an overall pore area of an overall area of the coating surface (31, 131) amounts to at least 30%, in particular to at least 40%.

Abstract: The present invention relates to a light-guiding system for improving the lighting conditions of the passenger compartment of a motor vehicle, including a light-generating unit (3) which can be switched on and off electrically and a light guide (5) which is used for guiding the light and which is coupled to the light-generating unit (3) for coupling in the light. According to the present invention, the light guide (5) is arranged in the area of the interior lining of the vehicle roof (1) and designed as a flat light guide, the light being coupled in at one or more lateral surfaces (7, 8) of the light guide (5); and the flat light guide (5) being prepared such that the light couples out of the light guide (5) into the passenger compartment (2) of the vehicle over a large surface and in a homogeneous manner.

Abstract: A vehicle interior trim which has a reduced glare effect at the windshield or the rear window, and comprises the following features: a transparent surface layer (2) whose upper boundary surface (7) has a non-smooth structure, partial areas of the boundary surface (1) being inclined toward the windshield or the rear window; a mat absorber layer (5) which is arranged underneath the surface layer (2); a zone which is situated between the surface layer (2) and the absorber layer (5) and which has a total reflection effect for light beams impinging into the vehicle interior at flat angles from outside; a device (7,8,9) for scattering the light so that a natural lightness appearance ensues for the vehicle passenger.
