Latest Patents

One of Yokoyama's latest inventions is the timer controlled multipole circuit breaker. This innovative device features a pair of breaker contacts in each pole, connected to load and line terminals. The circuit breaker incorporates an electric timer that controls the opening and closing of the contacts according to a predetermined timing schedule. This design allows the timer to be energized by the common power on the line terminals, eliminating the need for additional external wiring. Furthermore, the circuit breaker includes a safeguard that prevents automatic reclosing of the contacts until the fault current condition is resolved.

Another significant patent is a circuit breaker that consists of multiple breaker units. Each unit has a movable contact that can be separated from and engaged with a fixed contact through a manual mechanism. This mechanism is designed to close the contacts normally while retaining a tripping link that is released by a tripping means in response to excess current. The tripping link is interconnected with other units via a single coupling rod, allowing for simultaneous operation during a fault condition.
