Latest Patents

Shintani's latest patents showcase his innovative approach to addressing practical challenges in engine design. His first notable invention is a **Chain Guide for Use in Engine**. This patent describes a chain guide featuring longitudinal grooves with rectangular cross-sections formed by surface pressing in the metal base plate. These grooves are strategically positioned to align with the parts of the shoe surface contacted by the link plates on both sides of the roller chain, improving the guide's effectiveness.

The second patent is for a **Tensioner with Projection-Preventing Hook**, designed for timing chains and belts in internal combustion engines. This innovative tensioner includes a projection-preventing hook that secures a spring-urged plunger in a withdrawn condition before installation. During operation, the hook releases the plunger, enabling it to apply force on a pivoted tensioner lever. A resisting member on the fulcrum pin of the hook exerts friction, thereby preventing unintended return to its latched condition and minimizing operational noise. Notably, this tensioner can be mounted in any direction, simplifying the installation process.
