  • Patent number: 11247437
    Abstract: The invention relates to a method for producing a component from ceramic materials in which a plurality of layers are applied to a base body by means of screen printing or template printing, said layers being formed from a ceramic material, in each case in a defined geometry above one another in the form of a paste or suspension in which powdery ceramic material and at least one binder are included. At least one region is formed here within at least one layer having a defined thickness and geometry composed of a further material that can be removed in a thermal treatment and that is likewise applied in the form of a paste or suspension by means of screen printing or template printing. Electrically functional structures composed of an electrically conductive or semiconductive material are applied to and/or formed on and/or in at least of the ceramic layers prior to the application of a further ceramic layer.

  • Patent number: 5493290
    Abstract: A signal processing arrangement for absolute-value sensors in which, within the periodic structure (3) a measurement surface which is divided into a plurality of measurement sections lies opposite at least one probe, each measurement section representing a position marking. Inputs (E.sub.n) of the periodic sensor structure (3) are cyclically connected to a signal source (1) via a switch input group (2), and outputs (O.sub.n) of the periodic structure (3) are connected to an evaluation circuit. In order to convert the geometrical value into an absolute electrical image signal, at least one probe in combination with, in each case, one measurement section forms at least one switch unit for each measurement position (X.sub.i). Between the outputs (O.sub.n) of the periodic structure (3) and the evaluation circuit (5), a cyclically switching output switch group (4) is arranged, and the switch units (X.sub.
