Title: Eigo Tanuma: Innovator in Ceramic Filtration Technology
Introduction
Eigo Tanuma is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of ceramic filtration technology, holding a total of 3 patents. His work focuses on innovative methods for filtering molten metals, which are crucial in various industrial applications.
Latest Patents
Tanuma's latest patents include a ceramic filter and a method of filtrating molten metal using the same. This ceramic filter is designed to be arranged in a flow passage through which molten metal is poured from a gate into a cavity of a casting mold. The filter features a ceramic main body with a three-dimensional reticulated skeleton structure that has interconnected pores. The main body is formed into a cylindrical shape with an inner hollow portion. The method of making this ceramic main body involves applying a ceramic slurry on a reticulated synthetic resin foam that lacks cell membranes. The foam is then sintered, and the ceramic slurry is applied until the foam is removed through carbonization. Another significant patent is for a high-temperature ceramic filter, which is prepared by applying a ceramic slurry to a synthetic resin foam with an open cell three-dimensional reticulated skeleton structure, followed by drying and firing. This filter is particularly useful for the filtration of molten metals.
