Title: The Innovations of Hans-Jurgen Hirsch
Introduction
Hans-Jurgen Hirsch is a notable inventor based in Selfkant, Germany. He has made significant contributions to the field of electroradiography, holding a total of 3 patents. His work focuses on enhancing the quality and efficiency of imaging technologies, particularly in medical applications.
Latest Patents
One of his latest patents is an electroradiographic recording device. This device achieves high picture quality at low radiation intensities. It consists of a source of X-rays, an electrode that passes X-rays, and an intermediate recording space for the object to be displayed. Additionally, it features an electrode on the side remote from the recording space, which has a layer of dielectric material. A second electrode with a photoconductive layer is also included. The layers are separated by a gas gap bounded by side walls. A direct voltage source is in electrical contact with the electrodes. The photoconductive layer comprises a granular photoconductive material in a binder. The gas gap between the dielectric layer and the photoconductive layer ranges from 50 to 500 micrometers in width, and the electrode passing X-rays has a surface resistance between 10³ to 10⁸ Ohms.
Another significant patent is related to X-ray electrophotographic recording material and the method of manufacturing it. The sensitivity of photoconductive layers of tetragonal lead monoxide in a binder is enhanced when the tetragonal lead monoxide is subjected to further treatment. This process results in a grain size of 1 to 50 micrometers, which is dispersed in the binder without mechanical force and sedimented on a layer carrier without mechanical force.
