Title: Innovations of Inventor Jean Nicolas
Introduction
Jean Nicolas is a notable inventor based in Paris, France. He has made significant contributions to the field of high-frequency applications through his innovative patents. With a total of 3 patents, his work has had a considerable impact on the technology industry.
Latest Patents
One of his latest patents is focused on dielectric and non-magnetic ceramics for high-frequency applications. This invention involves dielectrics that do not exhibit any residual magnetization and are produced using a technique of ceramics sintered at high temperatures. These materials are particularly useful in devices operating at very high frequencies, such as the X band. They are obtained by sintering at lower temperatures than those typically used for known dielectrics suitable for such applications. The invention corresponds to two possible general formulae.
Another significant patent by Jean Nicolas is related to the method of manufacturing ferrimagnetic material for recording and read-out applications. This ferrimagnetic material enhances the efficiency and sensitivity of recording, read-out, and erase heads that work with magnetic layer devices. The manufacturing process begins with a solution of mineral salts or oxides of zinc, nickel, and iron. By employing physicochemical processes used in the ceramic industry, particularly sintering under pressure, polycrystalline ferrites with a spinelle structure are produced. These ferrites satisfy the general formula: Ni.sub.1-x Zn.sub.x Fe.sub.2(1+e) O.sub.4, where x ranges between 0.5 and 0.7, and e ranges between -0.08 and +0.015.
