Abstract: An optical encoder comprises an emitter; a receiver; a reflector; and a code carrier, wherein the emitter emits electromagnetic radiation along an emission axis in the direction of the reflector and the reflector deflects the electromagnetic radiation along a reception axis in the direction of the receiver. The code carrier is movably supported and has a sequence of code sections to interrupt or to give way for the emitted electromagnetic radiation to impinge on the detector in dependence on the position of the code carrier, wherein the emission axis and the reception axis extend at an alignment angle with respect to one another that has a value in the range from 30 degrees to 150 degrees.

Abstract: The invention relates to a method for producing metallic moulded bodies comprising a ceramic layer according to the membrane method, whereby a porous metallic membrane is used. The aim of the invention is to provide a cost-effective, rapid method which is as non-polluting as possible for producing metallic moulded bodies comprising a ceramic layer according to the membrane method using a porous metallic membrane, whereby the penetration depth, the green density and the deposition speed of the ceramic particles in the metallic membrane can be controlled. To this end, the porous metallic membrane is sealed by electrophoretic deposition of ceramic particles in the pores of the metallic membrane, the metallic membrane being arranged between two electrodes for the electrophoretic deposition, and the space between an electrode and the metallic membrane being filled with a dispersion containing the ceramic particles to be deposited in the pores and a dispersant.
