Abstract: PURPOSE: A scattered oil interference isolating structure on a breather line is provided to prevent the interference of scattered oil in an inlet of a breather line by installing a U-section pipe. CONSTITUTION: A U-section pipe(13) is installed in an inlet(6a) of a breather line, and a gas flow hole(14) is formed on the side of the U-section pipe. An oil drain hole(15) of which diameter is smaller than that of the U-section pipe is formed in the lower end of the U-section pipe. Most of scattered oil for the cooling and lubrication of a piston collides against the U-section pipe and falls to the lower end of a crankcase(3). As blow-by gas flows in through the gas flow hole, the inlet is not interfered by the oil. The blow-by gas collected in the crankcase is smoothly discharged to a rocker cover through the fully opened inlet. Some of the oil flowing into the U-section pipe falls by the gravity. Simultaneously the oil is separated from the blow-by gas and collected via the oil drain hole. Simply the blow-by gas moves to the rocker cover along the breather line.

Title: Multiple local oxidation for surface micromachining
Inventor: ISMAIL M SALLEH
IPC: B81C1/00
Filed: 1997-09-17
Abstract: PURPOSE: A multiple local oxidation (LOCOS) process is provided to shape the surface of a substrate in which the depression is smooth and relatively defect-free. CONSTITUTION: A multiple LOCOS (local oxidation) process shapes a surface of a substrate to form a series of planar regions which are vertically separated from each other. One exemplary process forms a hard mask layer for each LOCOS operation. Another exemplary process includes forming a silicon nitride mask layer and repeatedly changing the pattern of that mask layer. Each change in the pattern corresponds to a planar region to be formed; and after each change, oxide is grown in openings through the mask layer. The growth of oxide consumes part of the substrate and provides a vertical separation between the planar level corresponding to the pattern and a next higher planar level. Regions of the substrate once exposed by a mask pattern can remain exposed so that subsequent LOCOS operations maintain previously established separations between levels. A hard mask layer can include a polysilicon layer which protect a silicon nitride layer from conversion to oxide during the repeated LOCOS operations.
