Title: Yasuo Wakahata: Innovator in Varistor Technology
Introduction
Yasuo Wakahata is a prominent inventor based in Katano, Japan. He has made significant contributions to the field of electronic components, particularly in the manufacturing of varistors. With a total of 17 patents to his name, Wakahata's work has had a lasting impact on the industry.
Latest Patents
Wakahata's latest patents include a method for manufacturing varistors. This innovative method allows for the creation of varistors with high plating resistance and moisture resistance. The process involves selectively forming a compact high-resistance layer with a uniform thickness on the surface of a varistor element. The varistor element is constructed by alternately laminating ceramic sheets primarily made of zinc oxide and internal electrodes. After applying Ag electrode paste to the end faces of the element, it undergoes sintering through heat treatment. The element is then buried in SiO or a mixture containing SiO and heat-treated for 5-10 minutes at temperatures ranging from 600 to 950 degrees Celsius in either air or an oxygen atmosphere. Another notable patent involves an electronic component that features an internal electrode, an external electrode on the end portion of the element, and a protection layer made of metal oxide.
