摘要:
A method for correcting a mask pattern to be formed on a photomask used in a lithographic step of a semiconductor device fabrication process. The method includes the steps of extracting an isolated pattern having an optically isolated portion from the mask pattern and providing, in an adjacent pattern extending parallel to the isolated portion of the isolated pattern and having a terminal end, an extended portion extending from the terminal end next to the isolated portion of the isolated pattern along a direction in which the isolated portion of the isolated pattern extends.

The purpose of the present invention is to provide a method, whereby, in the dry fractionation of an oil or fat, a decrease in solid-liquid ,separation efficiency, said decrease being caused by the engulfment of a filtrate fraction into a crystal fraction after crystallization and press filtration, can be prevented and thus the crystal slurry can be efficiently separated after the crystallization. A method for the dry fractionation of an oil or fat, said method comprising, before or after crystallization, adding a definite amount of a filtration aid followed by mixing and then press-filtering the thus obtained crystal slurry. Thus, the crystal slurry can be easily separated into a crystal fraction with little engulfment of a liquid fraction and the liquid fraction.

In a breather device for engine, in which an inlet of a breather chamber communicates with a crank chamber through a reed valve, the reed valve being formed of: a fixed stopper plate arranged so as to be opposed to a valve seat formed on an end face of the inlet facing the breather chamber; and an elastic valve plate fixed at one end thereof to the stopper plate and capable of bending elastically to change its position from a closed position in which the elastic valve plate closes the inlet by seating on the valve seat to an opening limit position in which the elastic valve plate opens the inlet and abuts against the stopper plate, the stopper plate is provided at a center part thereof with an oil discharge hole through which oil present between the elastic valve plate and the stopper plate is pushed out when the elastic valve plate is pushed toward the opening limit position in which the elastic valve plate abuts against the stopper plate by pressure in the crank chamber. Accordingly, it is possible to prevent the elastic valve plate from sticking to the stopper plate even if oil mist adheres to the elastic valve plate or the stopper plate of the reed valve.
