Patent number: 8293020Abstract: A megasonic cleaning method and a megasonic cleaning apparatus are provided. Microcavitation bubbles may be formed by applying an electromotive force to a cleaning solution using a megasonic energy in a separate room from an object to be cleaned. The microcavitation bubbles having a stable oscillation among the formed microcavitation bubbles may be moved to the object to be cleaned. A surface of the object to be cleaned may be cleaned using the microcavitation bubbles having the stable oscillation. Particles attached onto the surface of the object to be cleaned may be effectively removed while preventing pattern damage.Type: GrantFiled: October 19, 2010Date of Patent: October 23, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-Hyuck Choi, Won-Jung Kim, Ho-Young Kim, Hyung-Ho Ko, Jong-Keun Oh, Chan-Uk Jeon, Keun-Hwan Park

Patent number: 8287655Abstract: A method of cleaning dirt and debris from surfaces using a cleaning device, such as a vacuum cleaner. The cleaning device has a handle unit which is attached to the body of the cleaning device adjacent a filter compartment. The handle unit has a handle portion that is spaced from the filter compartment to allow a user to place his or her hand through the space and grasp the handle portion and thereby carry the cleaning device using only the handle unit. The handle unit can also be detached from the body of the cleaning device, and then later re-attached, via lockable mating connecting elements.Type: GrantFiled: January 6, 2010Date of Patent: October 16, 2012Assignee: Stein & Co. GmbHInventors: Thomas Stein, Achim Liffers
