Title: Compact selenium diode matrix - has foil electrodes and contact strips supporting dielectric in concertina folded package
Inventor: STRUENKMANN JOERG ING GRAD
IPC: G11C17/06
Filed: 1976-06-24
Abstract: A selenium diode matrix with a number of cells each having a number of diodes connected electrically and mechanically by a common electrode but with individual counter electrodes connected in a matrix, capable of a large output from a physically small unit, and insensitive to climatic variations. The individual cells are isolated by gaps extending into the material around each counter electrode. The elements are arranged in strips equally spaced in a plane with foil electrodes and counter electrodes attached by adhesive. Strip conductors at right angles to the diode strips connect the corresponding diodes of each strip and connect at their ends to leads. These strips with the foils are perforated at points and a connection is made between the foil electrodes and the lead strips at these points by metal spraying or evaporation. The whole forms a flexible unit which may be concertina folded for compactness.
