Latest Patents
One of his latest patents is a "Method for fabricating laminate-type dielectric element." This innovative method produces a laminated dielectric element that is free of delamination. The process involves alternately laminating dielectric ceramic layers and base metal electrode layers. It includes steps such as printing electrodes, laminating ceramic green sheets, dewaxing the laminate, and sintering it to form base metal electrode layers. The method ensures that the amount of base metal oxide remaining in the electrode layers is not larger than 20% by weight, and the amount of lead liberated from the ceramic material is not larger than 30 atomic % within 5000 Å from the surfaces of the base metal electrode layers.
Another significant patent is the "Production method for laminate type dielectric device and electrode paste material." This invention provides a method for producing a laminate-type dielectric device that is free from peeling of the electrode layer and voids in both the electrode and ceramic layers. The electrode paste material used in this process contains CuO as a principal component, ensuring high conductivity and reliability in the final product.
