Title: Innovations of Tatsuru Takaoka

Introduction

Tatsuru Takaoka is a notable inventor based in Omihachiman, Japan. He has made significant contributions to the field of magnetic ceramics, holding a total of 3 patents. His work focuses on developing materials and components that enhance the performance of inductors.

Latest Patents

Takaoka's latest patents include a magnetic ceramic composition and an inductor using this composition. The magnetic ceramic composition contains ferrite as a primary component along with a sintering aid. This composition can be sintered at low temperatures, which is advantageous for manufacturing. The sintering aid consists of approximately 2-45 mol % Li2O, 5-40 mol % RO (where R is at least one of Ba, Sr, Ca, and Mg), and 30-70 mol % (Ti, Si)O2, with SiO2 accounting for at least 15 mol %. This innovative composition results in inductor elements that suppress the migration of inner conductors, thereby reducing insulation deterioration and increasing direct-current resistance.

Another significant patent is for a lamination type inductor array. This invention features a laminated body that includes a first insulating sheet with first internal conductors, a second insulating sheet with second internal conductors, and a protective sheet. The internal conductors define inductors, and the arrangement allows for a zigzag pattern that extends toward inner inductors when the distance between the end surfaces and the adjacent inductors is less than a fixed value.
