Abstract: A turbine housing includes an inner pipe that forms an exhaust air flow path in which a turbine wheel accommodating a turbine shaft is arranged; and an outer pipe that is spaced from the inner pipe at a predetermined distance and covers the inner pipe. At least one reinforcing plate is secured to an inner surface of the outer pipe.

Abstract: A setting machine for transplanting plugged seedlings of vegetables along predetermined transplantation ridges in a field used in combination with seedling culture trays made of synthetic resin and formed with cells as through-holes. The setting machine includes a taking-out device for supporting the seedling culture trays and for selectively taking the seedlings out of open bottoms of the cells successively. The taking-out device includes a selecting member adapted to be two-dimensionally positioned in a plane in parallel with the bottom surface of the seedling culture tray, and formed with selecting holes to be aligned with the cells of the seedling culture tray. The setting machine further includes a transfer device for forcibly transferring the seedlings taken out of the cells to a predetermined position by the action of negative pressure, and a transplanting device for transplanting the seedlings into the ground along predetermined transplantation ridges.
