Latest Patents

Koike's latest patents focus on the design and functionality of thermally responsive switches. The first patent describes a thermally responsive switch that includes a hermetically sealed container made of metal housing and a header plate. This design features at least one conductive terminal pin that is hermetically fixed in a through hole. A fixed contact is secured to the terminal pin within the container, while a thermally responsive plate is connected to the inner surface of the container. This plate reverses its curvature direction at a predetermined temperature. The switch also includes movable contacts that are electrically secured to the thermally responsive plate, utilizing a silver-tin oxide-indium oxide system contact. The container is filled with helium gas, maintaining an internal pressure of 0.3 to 0.6 atmosphere at room temperature.

The second patent also pertains to a thermally responsive switch, which includes a metal housing and a header plate. This design features a conductive terminal pin inserted through a hole in the header plate, along with a fixed contact attached to the terminal pin. The thermally responsive plate is connected to the container's inner surface and reverses its curvature direction at a predetermined temperature. Movable contacts are directly secured to the thermally responsive plate, using a silver-cadmium oxide system contact. The container is filled with helium gas, maintaining an internal pressure ranging from 0.38 to 0.68 atmosphere at room temperature, allowing for effective arc management during contact opening.
