Latest Patents

One of Haruo Fujimori's latest innovations involves a novel method of evaluating the corrosion resistance of metal materials. This method takes into account the inhomogeneity of alloy compositions, suggesting that varying Fermi levels of electrons at different positions within the alloy lead to differential susceptibility to corrosion. His findings indicate that certain parts of the alloy are more resistant while others are more prone to corrosion, governed by an exponential function of the potential difference within the electric double layer. Further guidance for designing corrosion-resistant alloys includes maintaining a low electron energy level in the valence band, ensuring the oxide film formed is an n-type semiconductor, and supporting a wide band gap.

Another significant patent pertains to a comprehensive plant monitoring and diagnosing system aimed at evaluating corrosion and operational conditions. By combining various plant status variables, such as apparatus operating conditions, environmental factors, and water chemistry information, Haruo Fujimori's system effectively updates and compresses data into a plant chart. This chart functions similarly to a clinical chart for personal health, allowing for periodic inspection data to be analyzed, enabling predictive diagnostics for plant operations.
