Latest Patents
One of his latest patents is for a multilayer ceramic capacitor that features a specific thickness ratio of the external electrode to the cover layer. This invention includes an element body of a roughly rectangular solid shape, constituted by dielectric layers alternately stacked with internal electrode layers of different polarities. The design incorporates a pair of cover layers that cover the top and bottom faces, with external electrodes formed on the end faces and at least one of the principal faces. The relationship between the thickness of the external electrode (Tt) and the thickness of the cover layer (Tc) is defined by the equation 1/30 ≤ Tt/Tc ≤ 4/5, with Tc being between 10 µm and 30 µm.
Another notable patent is a method for manufacturing multilayer ceramic capacitors. This method involves producing dielectric green sheets and internal electrode-printed green sheets, which are then stacked to create unsintered laminates. The process includes applying a ceramic paste to the side faces of these laminates to form side margins, ensuring that the final product has a greater thickness for the side margins than for the cover layers. The element bodies are then created through sintering, followed by the formation of external electrodes.
