Abstract: The present invention relates to a lyotropic chromonic liquid crystal composition, a method for manufacturing a lyotropic chromonic liquid crystal coating film and a lyotropic chromonic liquid crystal coating film manufactured thereby. The lyotropic chromonic liquid crystal composition of the present invention includes chromonic liquid crystal compounds and monomers each having opposing acid-base properties. Use of the lyotropic chromonic liquid crystal composition in the formation of optical films leads to improvements in electrical and optical properties such as mechanical strength, an insulating characteristic and a refractive index.

Abstract: The present invention relates to a novel epoxy resin having improved heat-resistance, thermal expansion properties and processability, and to a thermosetting resin composition comprising the same. To this end, the present invention provides an epoxy resin of Chemical Formula 1 as disclosed in the Description, an epoxy resin composition comprising the same, and a packaging, substrate and transistor formed thereof. When a composition that contains an epoxy resin with a specific side functional group according to the present invention and/or an epoxy resin with a specific core structure is cured, a filler forms a strong chemical bond with the epoxy resin, thereby maximizing filling effects of the filler for the epoxy resin. Moreover, with the specific core structure, heat resistance and heat expansion properties of a cured product are substantially improved (CTE is reduced), and enhanced glass transition properties, strength and processability are demonstrated.

Abstract: An improved lint trap device comprises an attachment device, a base tubular-shaped plastic net, and an end-sealing device. The attachment device further comprises a plastic strap having a plurality of teeth at the proximal strap end and a plastic receptacle having a couple of teeth at the inner, upper surface. The end-sealing device disposed at the proximal end of the base tubular plastic net comprises a pair of end rims and a sealing slider. The pair of end rims has a detent at the center. The sealing slider has a latch at the center for latching onto the detent. The base tubular plastic net of the main body forms a plurality of paired mesh fins which extend along both sides and are disposed on every individual thread around each perforation of the base plastic net. The plurality of paired mesh fins disposes inwardly at a certain angle to form a secondary screen adjacent to the base plastic net.
