Abstract: Disclosed is a passive matrix-addressable memory apparatus. The passive matrix-addressable memory apparatus comprises: a plurality of first electrode lines horizontally arranged with respect to each other; a plurality of second electrode lines disposed orthogonal to the plurality of first electrode lines to be horizontally arranged with respect to each other; a memory unit formed between the plurality of first electrode lines and the plurality of second electrode lines, and containing an electrically polarizable material exhibiting hysteresis; and a switch unit. The switch unit comprises: first electrodes of a cantilever structure respectively formed between the memory unit and the plurality of first electrode lines to be electrically connected to the plurality of first electrode lines; and second electrodes electrically connected to the memory unit to be spaced apart from the first electrodes to face the first electrodes.

Abstract: Disclosed is a washing machine, which prevents solidification of liquid detergent by rapidly recovering the liquid detergent left in a liquid detergent supply passage and a liquid detergent supply pump by forming a negative pressure differential by use of the liquid detergent supply pump for a set period of time after the supply of liquid detergent is finished.

Abstract: A laundry machine and a control method thereof are provided in which laundering ability may be improved while also improving efficiency and noise/vibration. The laundry machine employs a plurality of drum motions by varying drum rotational speed, drum rotational direction, and drum starting and stopping point, to provide different motion of laundry items in the drum.

Abstract: A facility for cleaning substrates such as semiconductor wafers includes a loading/unloading part, an aligning part where wafers are repositioned from a horizontal state to a vertical state, a cleaning part performing etchant-treating, rinsing, and drying processes for wafers and having a plurality of process chamber stacked, and an interface part where a transfer bath is disposed to transfer wafers between the process chambers. When the wafers are transferred between the process chamber, the transfer bath is filled with deionized water (DI water) to prevent their exposure to the air. Wafers drawn out of the loading/unlading part are repositioned from a horizontal state to a vertical state and are transferred to a first process chamber being one of the process chambers to be subjected to a part of processes.

Abstract: A laundry treating apparatus includes a cabinet, a tub provided in the cabinet, a drum rotatably provided in the tub for receiving laundry, a gasket provided between the cabinet and the tub, a plurality of spray nozzles provided at a lower part of the gasket for spraying wash water upward into the drum, and a pump for pumping wash water to the spray nozzles.

Abstract: A washing machine and an associated washing method are provided. The method may include supplying washing fluid into a drum containing laundry, repeatedly dropping the laundry while rotating the drum in a predetermined direction, and drawing the laundry towards or separating the laundry from the inner circumferential surface of the drum by repeatedly accelerating and decelerating the drum.

Abstract: A washing machine and associated washing method are provided. The washing machine may include a cabinet, a drum rotatably installed in the cabinet, and a spray nozzle provided inside the cabinet to spray washing fluid into the drum. A spraying direction of the spray nozzle may be varied based on a rotation direction of the drum to improve washing performance of the washing machine.

Abstract: The present invention relates to htSNPs for determining a genotype of cytochrome P450 1A2 (CYP1A2), 2A6 (CYP2A6) and 2D6 (CYP2D6), PXR and UDP-glucuronosyltransferase Ia (UGT1A) genes and a gene chip using the same, and more particularly, to a selection method of htSNPs for determining a haplotype of human CYP1A2, CYP2A6, CYP2D6, PXR and UGT1A genes, a method of determining a genotype of the genes by using the htSNPs and a gene chip therefor.

Abstract: The present invention relates to a clothing treating apparatus. The clothing treating apparatus includes a cabinet, a clothing holding unit in the cabinet for holding clothing, and a steam generator for generating steam or superheated steam to supply to the clothing holding space, thereby permitting to remove rumples from the clothing and microbes from the clothing possible to remain thereon.

Abstract: A laundry treatment machine and a washing method therefor are provided. The laundry treatment machine may discharge fluid by driving a drainage device, while rotating a drum during a time period between a plurality of rinsing operations. The rotation speed of the drum may be controlled to be lower than a reference speed, which is the rotation speed of the drum when laundry is not uniformly distributed in the drum, and thus, eccentricity of the laundry is high.
