  • Patent number: 10746303
    Abstract: To suppress static leakage in a seal device, a seal lip is configured for sliding contact with a seal flange that includes a thread groove exerting a fluid pumping action at a time of shaft rotation. The seal device prevents sealing fluid on the inner-machine side from leaking to the outer-machine side between a housing and a rotating shaft inserted into a shaft hole on the housing. The seal lip is attached to the inner periphery of the shaft hole and the seal flange is attached to the outer periphery of the rotating shaft. A sliding area in the seal flange in sliding contact with the seal lip is a flat surface with no thread grooves, and has an outer peripheral side area and an inner peripheral side area, which each have a thread groove exerting a fluid pumping action when the rotating shaft rotates.

  • Patent number: 9893498
    Abstract: A pair of electrode lugs clamp a bar at side surfaces of the bar so as to be electrically connected to the bar. The electrode lugs respectively include a first contact portion and a second contact portion having different front-back lengths. The bar is clamped such that the first contact portion having a short front-back length L1 opposes a back end portion of the bar within a range of the second contact portion having a front-back length L2. The back end surface of the bar is brought into contact with and welded to a front end surface of a metal shell by resistance butt welding. Since the first contact portion of one lug is short and is close to the abutting surfaces, heat dissipation can be reduced and heat concentration can be increased.
