Title: Masayuki Kasuya: Innovator in Catalytic Converter Technology

Introduction

Masayuki Kasuya is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of catalytic converter technology, holding a total of 6 patents. His innovative designs focus on improving exhaust gas purification systems, which are crucial for reducing environmental pollution.

Latest Patents

Kasuya's latest patents include a metal substrate for catalytic converters and a catalyst block. The metal substrate is designed as a base for supporting a catalyst for exhaust gas purification. It features a honeycomb structure created by superposing a metallic flat foil and a metallic wavy foil. The wavy foil has offset portions where adjoining wave phases are offset from each other. Additionally, an oxide coating film is formed in these offset portions, which includes exposed edge surfaces on the gas-inlet side. This coating comprises 30-99.9 mass % first alumina, with the remainder consisting of second aluminas, Fe oxides, and Cr oxides. The first alumina is identified as α-alumina, while the second aluminas include various forms such as γ-, θ-, η-, δ-, ζ-, and κ-aluminas.

The catalyst block is designed for cleaning exhaust gas and features a square-shaped honeycomb core with first to fourth outside surfaces. It includes a first plate attached to the first outside surface and a second plate attached to the second outside surface. An exterior frame encases the honeycomb core, the first plate, and the second plate, ensuring that the catalyst is supported within the honeycomb core and plates, but not in the exterior frame.
