Latest Patents
Yositani's latest patents include a breaker and a sealed contact device. The breaker features a contact unit housed in an airtight container, which includes fixed contact points and a movable contact point. This design allows for selective contact between the movable and fixed points. The breaker also incorporates a movable shaft that extends outward from the container, facilitating the movement of the contact point. Additionally, a metal member ensures the airtightness of the container while allowing for the movement of the shaft. The lever unit enables the movable shaft to transition between a closed position, where contact is made, and an open position, where contact is broken.
The sealed contact device consists of an electromagnet block, a contact block, and a case. The electromagnet block includes a coil bobbin, a movable iron core, a yoke, and a return spring. The contact block features a sealing container with fixed contact points and a movable contact member. This member is designed with first and second protrusions that are asymmetrically formed, ensuring that only one protrusion contacts the sealing container during rotation.
