Title: Haruo Shimada: Innovator in Silicon Production and Reinforcing Steel
Introduction
Haruo Shimada is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the fields of silicon production and reinforcing steel technology. With a total of 5 patents to his name, Shimada's work has had a lasting impact on materials science and engineering.
Latest Patents
One of Shimada's latest patents focuses on a production process and apparatus for high purity silicon. This innovative method allows for the production of high purity silicon by heating solid silicon dioxide (SiO) at temperatures between 1000°C and 1730°C. The process involves a disproportionation reaction where solid SiO is decomposed into liquid or solid silicon and solid SiO, with the produced silicon being separated from the SiO. Additionally, he has developed a method to obtain solid SiO by heating a mixture of carbon, silicon, or ferrosilicon with SiO to generate SiO gas, which is then cooled to produce solid SiO.
Another notable patent involves the creation of high-purity reinforcing steel that is resistant to salt. This steel is designed to prevent the deterioration of concrete over extended periods, especially when the salt content in the concrete does not exceed 0.5 wt % in terms of NaCl. The composition of this reinforcing steel includes specific percentages of carbon, silicon, manganese, phosphorus, sulfur, copper, tungsten, aluminum, and iron. Furthermore, Shimada has disclosed another type of reinforcing steel that can significantly retard concrete deterioration even under severe corrosive conditions.
