Latest Patents
Watanabe's latest patents include innovative methods and compositions for Fe-Ni alloys. One of his patents focuses on a method for producing a Fe-Ni alloy that is particularly useful for lead frames in the production of integrated circuits. In this composition, a specified amount of beryllium (Be) is added to enhance mechanical strength while maintaining the low thermal expansion characteristics typical of conventional Fe-Ni alloys.
Another significant patent involves the manufacturing of a shadow mask made from a Fe-Ni alloy. This alloy composition includes cobalt (Co), manganese (Mn), silicon (Si), and chromium (Cr) as major components. The additional inclusion of Be ensures high deformation resistance and facilitates easy pore formation through etching, without compromising the alloy's inherent low thermal expansion. Furthermore, the introduction of annealing at temperatures between 800°C to 1200°C during the production process effectively lowers the proof stress of the product, allowing for the creation of thin shadow mask materials that are well-suited for high-quality screen displays.
