Abstract: The vehicle seat is configured to improve child seat mountability, and to prevent deterioration in appearance design when the child seat is demounted. The vehicle seat includes an anchor storage recess formed in a pad that constitutes the seat for storing an anchor to be engaged with an engagement member attached to a child seat. The anchor storage recess is covered with a skin material having a slit. The slit has an inverse T-like shape.

Abstract: The vehicle seat (100) comprises a cover part (29) including a cover member (24) having a folded portion (24b) in the X direction at a position where it is overlapped with a hole part (21a) formed in a seat back (2), and a cover member (25) having a folded portion (25b) folded in the X direction at a position where it is overlapped with the hole part (21a). The cover part (29) includes two sewn parts (26, 27) for fixing the overlapped portion of the cover members (24, 25) in two locations in the Y direction, while no sewn part exists in such section of the overlapped portion as intervenes between the sewn parts (26, 27).

Abstract: A rack manufacturing apparatus and a rack manufacturing method are provided. The rack manufacturing apparatus includes a first support portion configured to support a hollow or solid first bar on which first rack teeth are formed, a second support portion configured to support a hollow or solid second bar such that an axial center line of the second bar is aligned with an axial center line of the first bar, a base configured to cause the second support portion to approach the first support portion, and a rotary driving portion configured to rotate the second support portion about the axial center line of the second support portion relative to the first support portion so as to join an end portion of the first bar and an end portion of the second bar by a friction pressure welding.

Abstract: A substrate processing apparatus includes a substrate heating part, a power supply part and a control device. The control device measures a temperature of the substrate while controlling the substrate heating part such that the temperature of the substrate reaches a first control temperature higher than the target temperature using power supplied by the power supply part. The device measures the temperature of the substrate for a second control temperature lower than the target temperature, and selects the power ratio value providing the best temperature uniformity in the plane of the substrate and a temperature average value for the selected power ratio value from a result of the measurement. The device calculates a control temperature and the power ratio value for the target temperature based on the selected temperature average value and the power ratio value for each of the first and second control temperature.
