Title: **Takehiko Otsuki: Innovator in Monolithic Ceramic Electronic Components**

Introduction

Takehiko Otsuki, an accomplished inventor based in Omihachiman, Japan, has made significant contributions in the field of electronic components. With a total of three patents to his name, his work focuses on developing innovative solutions that combine efficiency and functionality in electronic devices. His dedication to advancing technology is evident in his latest patented inventions.

Latest Patents

One of Otsuki's notable patents is for a **Monolithic Ceramic Electronic Component**, which features a sintered ceramic with a porosity of greater than about 30 percent and less than about 80 percent by volume. This innovative design ensures that the pores are filled with an epoxy resin, achieving a filling factor of about 40 percent by volume or more. The resulting component, such as a chip inductor, maintains a substantially unchanged self-resonant frequency when a direct current is applied. Additionally, it shows a remarkable rate of impedance decrease of about 50 percent or less at 100 MHz.

His second significant invention is a **Noise Filter** that includes a laminate body composed of magnetic layers, line conductors, and ground conductors. The design features one line conductor and one ground conductor alternately arranged at the interfaces between the magnetic layers. When an electrical signal is applied to the line conductors while grounding the ground conductors, the filter effectively attenuates high-frequency noise using the magnetic loss from the magnetic layer, showcasing his innovation in signal integrity.
