Patent number: 10244918Abstract: Provided are a dish washing machine capable of effectively removing garbage which remains at the bottom of a washing tub and a filter and a method of controlling the same. When washing water is sprayed from a nozzle while a vane is positioned at a reference position during a drainage operation, since a deflection angle of the vane is bent back and the washing water is strongly sprayed toward a rear wall of a washing tub, the washing water may form a fast and strong water current over a bottom plate of the washing tub, and the fast and strong water current may remove garbage which remains at a filter while flowing over the bottom of the washing tub. Also, even when an excessive amount of garbage is accumulated at a filter at a top end of a sump and blocks the filter during a washing operation such as preliminary washing, main washing, etc., the filter is automatically washed using a small amount of water, thereby eliminating inconvenience of a user to directly separate and wash the filter.Type: GrantFiled: May 11, 2018Date of Patent: April 2, 2019Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jung Chan Ryu, Woo Jin Shin, Soo Hyung Yoo, So Jeong Kim, Jun Ho Lee, Jae Man Joo, Sang Soo Choi

When water is sprayed from a nozzle while a vane is positioned at a reference position during a drainage operation, since a deflection angle of the vane is bent back and the water is sprayed toward a rear wall of a washing tub, the water forms a fast and strong water current over a bottom plate of the washing tub to remove garbage which remains at a filter while flowing over the bottom of the washing tub. Accumulation at a filter at a top end of a sump and that may block the filter during washing such as preliminary washing, main washing, etc., is washed, thereby eliminating the inconvenience of having to separate and wash the filter, and effectively improves performance by avoiding poor circulation of water that may occur due to a filter blockage or generation of bubbles.Type: GrantFiled: December 23, 2014Date of Patent: June 5, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jung Chan Ryu, Woo Jin Shin, Soo Hyung Yoo, So Jeong Kim, Jun Ho Lee, Jae Man Joo, Sang Soo Choi

Patent number: 8750064Abstract: A semiconductor memory apparatus includes a first switch, a second switch and a control unit. The first switch couples/separates a first bit line and a sense amplifier to/from each other in response to a first bit line separation signal. The second switch couples a second bit line and the sense amplifier to each other in response to a second bit line separation signal. The control unit generates a bit line separation signal for a refresh operation, of which enable period is shorter than that of the second bit line separation signal, and provides the generated bit line separation signal for the refresh operation to the second switch in the refresh operation.Type: GrantFiled: December 30, 2011Date of Patent: June 10, 2014Assignee: SK Hynix Inc.Inventor: So Jeong Kim
