Abstract: A display device includes: a base layer including a display area including an emission area and a non-emission area adjacent to the emission area, and a non-display area around the display area; a light emitting element in the emission area on the base layer; a color filter layer located above the light emitting element; and a light blocking pattern on the light emitting element and including a first light blocking pattern in the non-emission area and a second light blocking pattern in the non-display area. The first light blocking pattern and the second light blocking pattern are different in thickness from each other.

Abstract: A heat treatment method for unleaded brass alloy is provided to improve processability, cracking resistance, wear resistance and anti-corrosive property of unleaded brass alloy containing no lead or containing a very small amount of lead. The heat treatment method includes full annealing an unleaded brass alloy material, mechanical processing the material after full annealing and soft annealing the material after mechanical processing.

Abstract: A fuse type sprinkler has a body which is fastened to a drain pipe for spraying water through a drain formed inside, a valve of which an upper end is inserted into the drain of the body and to which a sealing unit is mounted along an upper end circumference to press and seal an inner surface of the drain, a frame which is fastened to the body to surround the valve and is provided with a hook on a lower end inner peripheral surface, a heat sensing unit which supports a lower end of the valve to allow an upper end of the valve to be inserted into the drain while being hooked by the hook of the frame, and is provided with a fuse which is separated from the frame to fall off when the fuse is fused by heat, and a deflector which is positioned inside the frame and falls off and is hung on the hook when the heat sensing unit is separated to distribute water sprayed through the drain.

Abstract: The present disclosure relates to a sprinkler head of fuse type, and more particularly, to a sprinkler head of fuse type which may perform an accurate and rapid elastically pressing operation when a fire occurs and particularly prevent any minute opening which may cause a fuse to be cooled due to a leaked fire fighting water and not to function.

Abstract: A scroll-type compressor has multiple discharge ports and blocks to prevent undesired movement of the non-orbiting scroll plate and an improved lubrication system.

Abstract: A scroll-type compressor has a scroll plate that is prevented from moving radially or rotating but may be axially displaced. The configuration includes a key and key way configuration and springs to axially bias one scroll plate away from the other scroll plate. The major components of the compressor assembly can be axially assembled.
