Latest Patents
One of Yuasa's latest patents is a method for producing mixed metal oxide compounds. This innovative process involves creating a precursor from multiple materials with different vapor pressures. The precursor and a source material are placed in a closed heat treatment furnace, where the source material, which shares some components with the precursor, is thermally treated. This method effectively suppresses the evaporation of specific materials in the precursor, leading to the formation of valuable compounds, including oxide superconductors and dielectric materials.
Another notable patent is the process of making a SQUID (Superconducting Quantum Interference Device) that features a tilt-boundary junction. In this process, an oxide film with a desired pattern is formed on a magnesia substrate. A superconducting oxide film is then applied to both the exposed areas of the substrate and the oxide film, creating a tilt-boundary junction. This junction functions as a Josephson junction, enabling the formation of a SQUID pattern on the substrate, which is essential for various applications in quantum computing and sensitive magnetic field detection.
