Latest Patents
One of Hirofumi Irie's latest patents is for an agitation mixer and feed pipe structure. This invention presents an agitation method for mixing a solution and a solvent to precipitate a solid substance from the solution. The method involves preparing an agitation mixer that includes an agitation vessel, an impeller rotated within the vessel, and a feed pipe connected to the vessel. The feed pipe features a multiple pipe structure, consisting of an outer pipe and an inner pipe arranged within the outer pipe. A shearing clearance is formed in the agitation vessel between the impeller and the feed pipe, allowing for effective mixing. The solution and solvent are sheared by the rotating impeller, which facilitates the precipitation of the solid substance.
Another significant patent by Irie is related to metal containers and their manufacturing method and apparatus. This invention describes a cylindrical metal container with a relatively large holding capacity, featuring triple seams with a vertically long, generally elongate rectangular cross-section. The seams have a convex, substantially semi-elliptical or semi-circular profile at the top and bottom. The design includes a pressed groove that runs parallel to the axis of the container, ensuring strong contact between the body and end plate flanges. A sealing compound is used to secure the seam, which is formed through a series of precise manufacturing processes.
