Title: Innovations of Hiroshi Kodama
Introduction
Hiroshi Kodama is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of engineering, particularly in the development of advanced materials and manufacturing processes. With a total of six patents to his name, his work has had a lasting impact on various industries.
Latest Patents
One of his latest patents is a light-alloy casting heat treatment method. This innovative method maintains the film boiling state of a refrigerant for a longer duration than previous techniques. By lowering the nuclear boiling start temperature, the material proof strength of the work exceeds thermal stress, which effectively reduces the cooling rate of the work. Additionally, by controlling the cooling rate during hardening, the refrigerant's film boiling state is sustained at a temperature that allows for optimal cooling. Another significant patent is the vibration-damping composite sheet steel. This invention consists of a viscoelastic material sandwiched between two steel sheets. A rust-proofing coating, which generates no gaseous matter, is applied to one surface of each steel sheet in contact with the viscoelastic material. This coating can either be a phosphate coating or a galvanized zinc coating, ensuring durability and effectiveness.
