With a total of three patents to his name, Okumura's work showcases his expertise and innovative spirit.
Latest Patents
Okumura's latest patents include a chain bearing, a chain pin, and a wear-resistant chain. The chain bearing patent describes a design where at least one member, such as a pin, features a surface layer made of vanadium carbonitride (VCN) coating. This coating is applied to the surface of a base material, and an oxide (VO) film of predetermined thickness is formed on the surface layer. This oxide film acts as a barrier between the surface layer and another member, such as a pin hole, that composes the chain bearing. The wear-resistant chain patent highlights a design that maintains high durability even in severe environments, such as those found in engine timing chains. This innovation incorporates a miniaturizing agent containing silicon during the vanadium cementation process of the steel base material, resulting in a surface-hardened layer with a crystal grain size of vanadium carbide reduced to 1 micrometer or less.
