Abstract: A filter assembly of a washer is disclosed, by which particles contained in water can be efficiently filtered off in the course of washing the laundry and by which the filtered-off particles are prevented from being discharged from the filter assembly. In a washer including an inner wall having an outlet and a circulation passage provided between the inner wall and a wash tub to enable water to circulate to the outlet from a bottom of the wash tub, the present invention includes a closed-type filter unit configured to filter off particles from the water discharged from the outlet and to prevent the filtered-off particles from being externally discharged.

Abstract: A washing machine includes a cabinet, a top cover provided at a top of the cabinet, and a lid hingedly coupled to the top cover, wherein the lid includes a transparent member defining a center thereof, a lower frame including a seating part where the transparent member is seated, and an upper frame coupled to the lower frame to support the transparent member.

Abstract: A laundry treating apparatus is disclosed. The laundry treating apparatus includes an outer case defining an appearance of the laundry treating apparatus, a washing tub arranged in the outer case, to receive laundry, a top lid mounted to a top of the outer case such that the top lid is openable and closeable, and an air flow assembly mounted to the top lid, to stepwise adjust a size of a passage communicating an interior of the outer case and an exterior of the outer case. The laundry treating apparatus can prevent moisture from staying in the interior of the laundry treating apparatus for a prolonged period of time, thereby preventing a failure of the laundry treating apparatus, generation of an offensive odor and propagation of bacteria in the interior of the laundry treating apparatus.

Abstract: A method for preparing polyolefin from alpha-olefin with high productivity using an internal circulating fluidized bed polymerization reactor is disclosed. The method for gas-phase polymerization of alpha-olefin comprising the steps of: supplying circulation gas including one or more alpha-olefins and inert gas into a polymerization reactor; polymerizing the alpha-olefin to polyolefin in two separated polymerization areas in the polymerization reactor; and discharging produced polyolefin from the polymerization reactor.
