  • Vacuum variable capacitor device
    Patent number: 6462930
    Abstract: An adjuster nut is rotatably supported to a vacuum container of a vacuum variable capacitor of a vacuum variable capacitor device. The adjuster nut has a nut portion, and a shank made of an insulating material. The shank has a first end integrated with the nut portion and a second end adapted to be directly coupled with a rotational shaft of a driving portion of the vacuum variable capacitor device. Another type of the adjuster nut has a deformable bellows, a nut portion, and a shank made of an insulating material. A second end of the nut portion is coupled with a first end of the bellows. The shank has a first end coupled with a second end of a bellows, and a second end adapted to be directly coupled with the rotational shaft of the driving portion of the vacuum variable capacitor device.
