Abstract: An engine combustion chamber structure includes a combustion chamber of an engine and a fuel injection valve. The fuel injection valve injects fuel toward a cavity in a crown face of a piston. The cavity includes a first cavity provided in a radially central region of the crown face with a first bottom having a first depth, a second cavity provided in an outer side of the first cavity with a second bottom having a second depth being smaller than the first depth, a connecting portion, and a standing wall region disposed further in a radially outer side than the second bottom of the second cavity. The second bottom is provided lower than an upper end, of the connecting portion. A lower section of the standing wall region is provided further in a radially inner side than an upper edge of the standing wall region.

Abstract: A proximity exposure method, wherein a mask (M) of which the master patterns (31) are formed larger than the resolution limit of the resist (R) is prepared with respect to the resist patterns (43) having the minimum pitch (P) equal to or smaller than the resolution limit of the resist (R); in the first exposure step, the mask (M) and the workpiece (W) are relatively step-moved by the pitch (P) of the resist patterns (43) after the mask patterns (31) are exposed and transferred onto the workpiece (W); and in the second exposure step, the mask patterns (31) are exposed and transferred onto the workpiece (W) again.

Abstract: In one embodiment, a semiconductor manufacturing apparatus includes a supporter configured to support a wafer. The apparatus further includes a first member including a first portion that faces a first region on an upper face of the wafer and a second portion that intervenes between the wafer and the first portion. The apparatus further includes a second member including a third portion that faces a second region on the upper face of the wafer and a fourth portion that intervenes between the wafer and the third portion. The apparatus further includes a first liquid feeder configured to feed a first liquid for processing the wafer to the first region, a first gas feeder configured to feed a first gas between the wafer and the first portion, and a second gas feeder configured to feed a second gas between the wafer and the second portion.

Abstract: A diesel engine comprises: a cylinder head covering one end of a cylinder; a piston having a crown surface opposed to the cylinder head, and performing a reciprocating movement within the cylinder; and a fuel injector attached to the cylinder head. The cylinder head is formed with an intake port so as to generate a swirl flow within the cylinder. The crown surface of the piston is formed with a cavity which is recessed toward an opposite side of the cylinder head and which has a circular shape in planar view, and a notch which is recessed radially outward from a peripheral edge of the cavity. The fuel injector is formed with an injection hole oriented toward an inside of the cavity.

Abstract: An exposure method includes the steps of: detecting an alignment mark of a work W and an alignment mark of a mask M by an alignment camera 152; calculating a positional shift amount between the mask M and the work W and a distortion amount of the work W, based on a shift amount between both the alignment marks detected by the alignment camera 152; adjusting an alignment between the work W and the mask M, based on the calculated positional shift amount; and correcting a curvature of a plane mirror 166 for reflecting a light beam of exposure light from a light source 161, based on the calculated distortion amount, at the same timing as the alignment adjustment step or at a different timing from the alignment adjustment step.
