  • Publication number: 20200158130
    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.

  • Patent number: 10479116
    Abstract: A base material processing apparatus includes first and second edge sensors and a displacement amount calculation part. The first edge sensor acquires a first detection result (R1) by detecting the position of an edge of a base material in a width direction at a first detection position. The second edge sensor acquires a second detection result (R2) by detecting the position of the edge of the base material at a second detection position. The displacement amount calculation part calculates the amount of displacement in the position of the base material in the transport direction or the amount of difference in the transporting speed of the base material on the basis of the first and second detection results (R1, R2). Thus, the amount of displacement in the position or the amount of difference in the transporting speed can be detected without depending on images such as register marks.
