Title: Juji Kato: Innovator in Multilayer Inductor Technology

Introduction

Juji Kato is a prominent inventor based in Tokyo, Japan. He is known for his innovative contributions to the field of electrical engineering, particularly in the development of multilayer inductors. His work focuses on enhancing the efficiency and performance of electrical components.

Latest Patents

Juji Kato holds a patent for a multilayer inductor that provides improved DC superposition characteristics. This invention utilizes a permanent magnet that emits a bias magnetic flux, along with a low-loss material as a magnetic body to enhance converter conversion efficiency. The multilayer inductor features a plurality of laminated electrically insulating magnetic layers and laminated conductive patterns. Each conductive pattern is connected in sequence in the lamination direction, forming a spiral coil inside the magnetic layer. The design includes a magnetized annular permanent magnet layer that emits a magnetic flux in a direction opposite to that of the magnetic flux excited by the coil. This configuration ensures that the conductive patterns do not overlap with the inner peripheral part of the magnet layer, effectively blocking the space between the conductive patterns and the magnet layer.
