Abstract: A method for forming a pattern includes forming a photosensitive film by coating a photosensitive resin composition on a substrate, exposing the photosensitive film to light through a mask that includes a light transmission region and a non-light transmission region, coating a developing solution on the photosensitive film, and forming a photosensitive film pattern by baking the photosensitive film, wherein the photosensitive resin composition includes an alkali soluble base resin, a photoacid generator and a photoactive compound.

Abstract: The present invention is concerned with an edible plant oils from which saturated fatty acids were removed and manufacturing process thereof. In order to remove saturated fatty acids from the edible plant oils; 1) Saturated and unsaturated fatty acids bound on same triglyceride molecules of edible plant oils were segregated each other as alkylesters of fatty acids by conventional transesterification reaction in which edible plant oils were treated with large excess of absolute C1˜C8 alkanol under the presence of catalytic amount of alkali- or alkali-earth metal-C1˜C8 alkoxide. 2) The alkyl-esters of mixed fatty acids were treated with C1˜C8 alkanol solution of urea to remove the alkylester of saturated fatty acids by conventional fractional crystallization as urea complexes of saturated fatty acid-alkylesters.

Abstract: A non-rotating electrodeless high-intensity discharge lamp system using circularly polarized microwaves. The lamp system has a first rectangular waveguide to propagate linearly polarized microwaves generated from a microwave source; an input circular waveguide linearly connected to the first rectangular waveguide; a second rectangular waveguide closed at an end thereof, and perpendicularly connected to a circumferential surface of the input circular waveguide; an elliptical waveguide linearly connected to the input circular waveguide such that the major axis of the elliptical waveguide is rotated to a predetermined angle relative to a horizontal surface of the input rectangular waveguide; a second circular waveguide linearly connected to the elliptical waveguide; and a discharge lamp housed in a mesh cover, and supported by the second circular waveguide while being held on a reflecting mirror.

Abstract: A non-rotating electrodeless high-intensity discharge lamp system using circularly polarized microwaves is herein disclosed. In an embodiment, the lamp system has a first rectangular waveguide (1) to propagate linearly polarized microwaves generated from a microwave source; an input circular waveguide (2) linearly connected to the first rectangular waveguide; a second rectangular waveguide (3) closed at an end thereof, and perpendicularly connected to a circumferential surface of the input circular waveguide; an elliptical waveguide (4) linearly connected to the input circular waveguide such that the major axis of the elliptical waveguide is rotated to a predetermined angle relative to a horizontal surface (or the wider surface) of the input rectangular waveguide; a second circular waveguide (6) linearly connected to the elliptical waveguide; and a discharge lamp (5) housed in a mesh cover (7), and supported by the second circular waveguide while being held on a reflecting mirror (9).
