Title: The Innovative Contributions of Tadashige Konno
Introduction
Tadashige Konno is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced coil components and EMI filters. With a total of 4 patents to his name, Konno's work reflects a deep understanding of electromagnetic technology.
Latest Patents
One of Konno's latest patents is a coil component that features first and second coil conductors with a spiral form, strategically placed between first and second magnetic substrates. The design includes first parts that extend alongside each other with a predetermined gap on a first insulating layer, and second parts that intersect three-dimensionally. This innovative configuration allows the coil conductors to intersect in their middle part when viewed from a direction orthogonal to the principal face of the magnetic substrates.
Another notable patent is a feed-through EMI filter that utilizes a metal flake composite magnetic material. This filter consists of a hollow outer conductor and an inner conductor that passes through it. The composite magnetic material, made of magnetic metal flakes, is positioned between the outer and inner conductors. This design enhances the filter's performance at GHz frequencies, providing a higher complex relative permeability than traditional ferrites and resulting in a significant insertion loss.
