Title: The Innovations of Karl-Heinz Kassel
Introduction
Karl-Heinz Kassel is a notable inventor based in Belecke, Germany. He has made significant contributions to the field of electrophotographic recording materials. With a total of seven patents to his name, Kassel's work has advanced the technology used in this area.
Latest Patents
Kassel's latest patents focus on methods for producing electrophotographic recording materials. One of his innovative methods involves creating a dual layer of amorphous and crystallized selenium on an electrically conductive substrate. In this process, tellurium is vapor-deposited in a vacuum onto the surface of the conductive substrate to form a tellurium layer. This layer has a thickness of about 0.5 to 5 nanometers. Subsequently, selenium is vapor-deposited onto the tellurium layer to a thickness of about 20 to 100 microns, resulting in the dual layer of amorphous and crystallized selenium. Another patent describes a similar process where a tellurium layer, with a thickness of 10 to 500 nanometers, is applied onto the surface of the carrier before selenium is vapor-deposited.
