  • Patent number: 11015612
    Abstract: A turbine housing includes an inner pipe and an outer pipe, the inner pipe being configured to form an exhaust air flow path between an exhaust-air-inlet-side flange and an exhaust-air-outlet-side flange, and an outer pipe being configured to cover the inner pipe such that a predetermined spacing is formed between the inner pipe and the outer pipe. The inner pipe has: an inner pipe main body configured to form the exhaust air flow path having a spiral shape, the inner pipe main body being connected to the exhaust-air-inlet-side flange such that exhaust gas is allowed to enter between the inner pipe and the outer pipe; and an exhaust tube attached to an exhaust air outlet side of the inner pipe main body in a freely slidable manner with an intervening sealing member.
    Type: Grant

  • Patent number: 9278405
    Abstract: In a multi-electrode welding torch, electrodes (2) are configured into a shape that has an arc-shaped curved surface area (R) in at least a portion of a cross-section thereof that is orthogonal to the longitudinal direction thereof. Collets (4) are each provided with a groove portion (4a) in which an electrode (2) is fitted, and whose inner wall surfaces (4b) come into contact in a plurality of locations with the curved surface area (R) when viewed in the longitudinal direction of the electrode (2).
