Title: Hiroki Nagashima: Innovator in Catalyst Technology

Introduction

Hiroki Nagashima is a prominent inventor based in Kakegawa, Japan. He has made significant contributions to the field of catalyst technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.

Latest Patents

One of his latest patents is titled "Apparatus for Coating Catalyst Slurry." This invention features a coating apparatus that includes a supply frame for delivering slurry into channels from one end of a honeycomb substrate. It also incorporates a blower for evacuating a wind box. An annular resistive member is attached to the circumference of the wind box opening, with the honeycomb substrate arranged on a spacer placed on the resistive member. The design ensures that when the blower operates and the slurry is supplied, the coat width of the slurry on the inner surfaces of the channels in the outer circumferential area is less than that in the center area.

Another significant patent is "Exhaust Gas-Purifying Catalyst and Method of Manufacturing the Same." This invention addresses the need for an exhaust gas-purifying catalyst that maintains its activity even in high-temperature atmospheres with high oxygen concentrations. The catalytic layer comprises an oxide particle, a simple oxide of alkaline-earth or rare-earth elements, and alumina or aluminum hydroxide. The oxide particle includes a rare-earth element and/or zirconium, along with a composite oxide and precious metal. The composite oxide contains an alkaline-earth element and at least one rare-earth element or zirconium, forming a solid solution with part of the precious metal.
