Abstract: Disclosed are a lift unit for a drum-type washing machine, and a drum-type washing machine comprising the lift unit. The lift unit is protruded from an inner wall of a drum for lifting the laundry in the drum, and comprises a water storage unit formed at at least one side surface of the lift unit for lifting and dropping the wash water when the drum is rotated. The lift unit lifts the wash water to a designated height and then drops the wash water according to the rotation of the drum, thereby circulating the wash water in circumferential and vertical directions of the drum, forming various water currents, and improving washing and rinsing efficiency.

Abstract: Disclosed is a drum-type washing machine provided with a plurality of vanes, each including two inclined side surfaces, which are concave, installed at an inner wall of a drum so that the laundry is easily caught on the inclined side surfaces while the caught laundry does not easily slip from the inclined side surfaces, lifted up a certain height by the rotation of the drum, and subsequently drops by its own weight, thereby increasing the agitation of the laundry and size of the contact surfaces of the inclined side surfaces with the laundry and the wash water and improving the washing and rinsing performance of the drum-type washing machine.

Abstract: A lift of a drum-type washing machine is constructed as a tandem-structure lift, which includes outer and inner lift parts. The outer lift is axially installed on an inner circumferential surface of a rotating drum provided with a multitude of water penetration holes, and the inner lift part is provided with an open bottom and perforations throughout its surfaces and is slidingly installed within the outer lift part. The outer lift part has an open top and an open bottom, with the open bottom facing at least a portion of the water penetration holes. Three such lifts, spaced equidistantly around the drum, are typically provided in a drum-type washing machine. As the drum rotates, the inner lift parts protrude, one by one, through the open top of the corresponding outer lift part, causing laundry to fall a greater distance and allowing washing water to spray through the perforations onto the laundry.

Abstract: A method and system of determining circuit performance-related characteristics, particularly delay and crosstalk, of interconnects includes defining a number of process variables which exhibit Gaussian distributions with respect to geometrical variances. A table of statistically based worst-case values representative of capacitances and resistances associated with different selections of the process variables is generated. In the preferred embodiment, the statistically based worst-case values are 3-sigma values. Also generated is a table of capacitance derivatives with respect to interconnect geometries. When a particular interconnect layout having selected process parameters is designated, the tables of 3-sigma values and derivatives are accessed to generate a resistance-capacitance (RC) net representative of the interconnect layout. The resistance and capacitance are correlated for each RC net and are partially determined by a randomized selection of values for geometries of the interconnect layout.

The invention includes a method for estimating distributed capacitance between interconnection lines within an integrated circuit. The integrated circuit is modeled as including a middle plane which is planar and adjacent to a top plane and a bottom plane. Each plane includes a plurality of interconnection lines which are infinite in length and parallel. The interconnection lines of the middle plane are orthogonal to the interconnection lines of the top plane and the interconnection lines of the bottom plane. A ground plane is adjacent and planar to the bottom plane. A first value of capacitance between an interconnection line of the middle plane and an interconnection line of the top plane is estimated ignoring the effects of the bottom plane.
