Abstract: A substrate treating apparatus includes a carrier platform, a transport mechanism, and a controller. The carrier platform places a carrier thereon. The carrier includes a plurality of shelves arranged in an up-down direction. The shelves are each configured to place one substrate thereon in a horizontal posture. The transport mechanism is configured to transport a substrate to a carrier placed on the carrier platform. The controller controls the transport mechanism. The transport mechanism includes a hand and a hand driving unit. The hand supports a substrate. The hand driving unit moves the hand. The controller changes a height position of the hand when the hand is inserted between two of the shelves adjacent to each other in the up-down direction, depending on a shape of a substrate taken from or placed on one of the shelves by the transport mechanism.

Abstract: When an accelerator opening degree becomes zero, a fuel cut-permission vehicle speed is set on the bases of a cooling water temperature. During a delay time, torque reduction has the characteristic of being dependent on cooling water temperature, and in an unwarmed state, a relatively large amount of air is supplied. The fuel cut-permission vehicle speed has the characteristic of taking a high value when an engine is not warmed up and cooling water temperature is low, in accordance with delay time air amount reduction control, which is performed in accordance with cooling water temperature. This reduces any shocks or odd feelings experienced by an occupant.
