Title: Souji Nishikawa: Innovator in Alloy Powder Production and Weir Assembly Technology
Introduction
Souji Nishikawa is a notable inventor based in Osaka, Japan, recognized for his contributions to the field of material science and hydraulic engineering. He holds two patents that showcase his innovative approaches to producing fine alloy powders and developing flexible weir assemblies.
Latest Patents
Nishikawa's latest patents include a method of producing alloy powders and a set-up/down plural-span weir assembly made of flexible sheets. The method of producing alloy powders aims to provide a technique for obtaining fine alloy powders that are extremely small in particle size, high in purity, and uniform in composition. This invention involves mixing a trivalent titanium compound with a complexing agent in an aqueous solution containing multiple types of metal ions, allowing for simultaneous deposition of these metals. The resulting fine alloy powders, with particle sizes ranging from 1 to 100 nm, exhibit characteristics suitable for soft magnetic materials and can be used in various applications, including molding materials and electromagnetic shielding.
The set-up/down plural-span weir assembly consists of multiple single-span weirs connected through pillars across a river stream. This innovative design allows for the inflation and deflation of the weirs using a pressure medium, enabling effective management of water levels. The upstream water is introduced into the weir assembly through a detection pipe, ensuring efficient operation.
