CONSTITUTION: In a converter which is used in a steelmaking process where molten pig iron is refined into molten steel, and has a tap hole, a fresh added sleeve is characterized in that it forms a tapered cylindrical pipe (70) for being inserted into the tap hole and an inner diameter of sleeve (52) made of refractories on outer side of the cylindrical pipe (70) so that the cylindrical pipe (70) is melted so as to be discharged, and the inner diameter of sleeve (52) is fixed to an inner wall side of the tap hole as the molten steel is being flown in the tap hole. A method for installing a fresh added sleeve consists the process of fixing the tap hole sleeve to the tap hole by spraying a spray material on inner side of the tap hole after inserting the fresh added sleeve into the tap hole by adhering clay to outer side of the inner diameter of sleeve (52) so as to fix a fresh added sleeve of tap hole to the tap hole.

Title: Method for aligning semiconductor wafer
Inventor: PARK SANG GYU
IPC: H01L21/027
Filed: 1999-09-09
Abstract: PURPOSE: A method for aligning a semiconductor wafer is provided to improve a process speed by shortening the time taken until the semiconductor wafer is aligned, and to transcribe a desired pattern on the semiconductor wafer by making a precise focusing in an exposure process. CONSTITUTION: An interval between the first and second patterns formed on a semiconductor wafer is measured at a plurality of respective positions on the semiconductor wafer while the semiconductor wafer is moving. A position of the semiconductor wafer is determined at the plurality of positions when the interval between the first and second patterns approximates to a predetermined value most closely. The semiconductor wafer is aligned with reference to a mean value of the positions of the semiconductor wafer at the plurality of the respective positions.

Abstract: PURPOSE: An oil pan is provided to compactly and easily connect cooling water pipes by installing a cooling water path in an oil pan. CONSTITUTION: An oil pan(40) having a wall(40'), a bottom(40") and a space(41) are mounted at the lower portion of an engine to supply lubricating oil to the piston of the engine and a cylinder wall. A cooling water pipe is formed through the wall in the shortest distance. For easy piping without interruption by a crank shaft, a cooling water path unit(45) is formed through the space. The cooling water path unit is composed of at least one among a hollow core protrusion(46) or an insert pipe(47). The cooling water path unit has an inclined corner for easy piping. The insert pipe has a flange on each end. Cooling water flows via the cooling water path unit, and the cooling water pipe is installed without passing through the upper or front portion of the engine. According to compact structure of the engine, the engine is conveniently installed in such a small place as a ship.

Title: Method for manufacturing micro switch
Inventor: PARK JAE YEONG
IPC: H01L21/82
Filed: 1999-09-21
Abstract: PURPOSE: A method for manufacturing a micro switch is provided to reduce time taken to manufacture the switch device, by eliminating a sacrificial layer within a short period of time by using a wet-etching method. CONSTITUTION: The first metal is formed and patterned on a substrate(1) to form a plurality of molds, and the second metal is deposited in the plurality of molds. The first metal is formed on the entire surface, and is selectively patterned to expose the second metal formed on both side molds to form a plurality of via molds. The third metal is deposited in the plurality of via molds. After a seed metal layer(12) and a sacrificial layer are sequentially formed on the entire surface, the sacrificial layer is patterned to form a mold across the third metal, and the fourth metal is deposited in the mold. After the sacrificial layer is removed, the first metal is eliminated by a wet-etch process.
