Latest Patents

One of her latest patents is the "Thermal Conductive Stress Relaxation Structure." This invention involves a structure interposed between high-temperature and low-temperature substances to facilitate heat transfer. The assembly is designed to allow a thermal conductive material to gather in a non-bonded state, providing a stress relaxation effect. The rolled-up body consists of alternating carbon-based and metal-based sheet materials, which create interfaces that enable adjacent parts to slide, thus dividing a deformable region to alleviate thermal stress. This innovative structure effectively suppresses thermal stresses and shape changes in the materials involved.

Another notable patent is the "Oriented Amorphous Carbon Film and Process for Forming the Same." This film primarily contains carbon, with specific percentages of nitrogen and hydrogen. It exhibits a unique structure that results in high electric conductivity. The film can be produced using a DC plasma CVD method, which involves generating an electric discharge through a reaction gas that includes various compounds. This invention showcases Yamada's expertise in developing advanced materials with practical applications.
