Title: Hironori Namba: Innovator in Optical and Magnetic Technologies

Introduction

Hironori Namba is a notable inventor based in Niigata-ken, Japan. He has made significant contributions to the fields of optical and magnetic technologies, holding a total of 3 patents. His innovative work has impacted various industries, showcasing his expertise and creativity.

Latest Patents

One of Namba's latest patents is a light receiving device that includes an optical substrate disposed over a light receiving surface. This device features a first optical multilayer film on the incident surface, a second optical multilayer film on the opposite surface, and a third optical multilayer film on the light receiving surface. It is designed to transmit light of two distinct wavelength regions while blocking other wavelengths. The first wavelength region is on the short wavelength side, and the second is on the long wavelength side. The device ensures that a predetermined proportion of light from the second wavelength region is transmitted, while the transmittance of the first wavelength region is limited within a specific range.

Another significant patent by Namba involves a thin-film magnetic head that projects an element part toward a recording medium through thermal expansion. This magnetic head comprises a reproducing element on an undercoat film, a recording element above it, and a heater that generates heat to project the reproducing element toward the recording medium. A shield layer is strategically placed between the reproducing element and the heater, consisting of multiple layers, including first and second shield layers. The second upper shield layer, located closer to the heater, is made from a material with a smaller coefficient of thermal expansion than that of the first shield layer.
