Disclosed are an engine having a cylinder block and a method for manufacturing an engine having a cylinder block. The engine may include cylinder liners each having a cylinder space formed therein, a protruded portion formed on an outside circumference thereof, and a flat surface formed on one side of the protruded portion. The cylinder liners may be arranged such that the flat surfaces of adjacent cylinder liners are in close contact with one another. The engine may also include a liner covering unit formed to surround an outside of the cylinder liners, and an outer block which forms a cooling water chamber with an outside surface of the liner covering unit.

An oil pump for a vehicle including a sealing apparatus is provided for preventing leakage of oil from the regulator chamber. The oil pump includes a sealing chamber formed between the outer ring and the housing, a sealing apparatus disposed in the sealing chamber, and an oil passage formed in the outer ring to facilitate a fluid communication of the sealing chamber with the regulator chamber. The sealing apparatus includes a contact portion, first and second sealing members. The first sealing member closely contacts the contact portion if the second sealing member is pushed by the hydraulic pressure of the regulator chamber supplied thereto through the oil passage, and thus prevents leakage of oil from the regulator chamber.

An apparatus of forming a fine pattern includes a chamber having a predetermined process space, a stage for supporting a substrate on which a photosensitive organic layer is formed, using buoyancy, a template disposed away from the stage to imprint a preprocess pattern dividing etching and non-etching regions on the organic layer of the substrate, and a driving unit for moving the stage toward the template so that the pattern formed on the template can be formed on the organic layer of the substrate.
