Latest Patents

Among his latest patents, one notable invention is a device for manufacturing electrets. This device is designed to create a thin sheet electret of small size with a uniformly distributed charge, even at the edges. It utilizes a grounded electrode to support a dielectric that needs to be charged, along with means for generating ions in the vicinity of the dielectric. Additionally, a grid extends parallel to the surface of the dielectric, raised to a different electric potential, and a conductive frame surrounds the dielectric, forming a single block with the electrode. Another significant patent involves the process of making SiO.sub.2 electrets. In this process, a layer of SiO.sub.2 is formed on a solid substrate through chemical vapor deposition, followed by thermal treatment to enhance its properties before electrical charging.
