Title: Innovations in Metal Wire Manufacturing by Tatsuo Hamashima
Introduction
Tatsuo Hamashima is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of metal wire manufacturing, holding a total of 2 patents. His innovative methods have paved the way for advancements in producing high-quality thin metal wires.
Latest Patents
Hamashima's latest patents focus on methods of manufacturing thin metal wire. The first patent describes a technique for producing a thin metal wire with a circular cross-section. This method involves providing molten metal within an extruding device equipped with a nozzle. A strip of liquid coolant, moving at a speed of 200 m/min or more, is introduced. The molten metal is extruded into this coolant strip, allowing for cooling and solidification, resulting in a high-quality thin metal wire. The process is designed to economically and continuously produce wires on a commercial scale, effectively creating wires with amorphous, non-equilibrium crystalline, or microcrystalline structures.
The second patent also details a method for manufacturing thin metal wire. In this approach, molten metal is spouted through a spinning nozzle and brought into contact with a layer of liquid cooling medium on a moving grooved conveyor belt. This method quench and solidifies the molten metal, enabling the continuous production of high-quality thin metal wire economically. It is particularly effective in producing wires with similar structural characteristics as mentioned in the first patent.
