Patent number: 10829881Abstract: The present disclosure provides a door lock device for releasably locking a door of a washing machine. The door lock device has first to third latches, and a drive motor and a latch drive mechanism for moving the third latch. The first latch releasably locks the door of the washing machine and is movable in frontward and rearward directions. The movement of the first latch is changed at a change position. The first latch is always biased frontward by a spring. The second latch releasably locks the first latch, which locks the door of the washing machine, at a door locking position. The third latch is moved in a direction perpendicular to the movement direction of the first latch. The third latch restricts the first latch at the door locking position, or unlocks the first latch after pushing the first latch from the door locking position against the spring.Type: GrantFiled: November 21, 2016Date of Patent: November 10, 2020Assignee: SCD CO., LTD.Inventor: Jae Hyoung Choi

Patent number: 10139146Abstract: An apparatus and a method for driving an icemaker for making ice cubes in a refrigerator. An ice-full state is sensed in such a way as to rotate an ejector and a cam gear in a reverse direction (opposite to an ice-ejecting direction), thereby preventing interference with the ice cubes present in the icemaker and thus enabling the ice-full state to be accurately sensed. A first torsion spring is mounted to an intermediate gear with a small rotation angle ratio to allow only a minimum amount of torque to be transferred to other components such as an ice-detecting lever, thereby increasing the durability of the components and providing a precise rotation force. The axial center of rotation of a second torsion spring is defined at a position that faces the other end (the revolving end) of the ice-detecting lever, to allow a minimum moment to be substantially constantly applied.Type: GrantFiled: May 10, 2013Date of Patent: November 27, 2018Assignee: SCD CO., LTD.Inventor: Jin Sung Park

Publication number: 20150362241Abstract: A driving device of an icemaker for refrigerator may include: a case 100; a driving unit 110 mounted in the case 100, including a gear unit 104 having a magnet M formed thereon and a motor M connected to the gear unit 104, and configured to drive an icemaker of a refrigerator; and a housing 100b into which the case 100 including the driving unit 110 is detachably inserted. Since the driving device of the icemaker is assembled as a module, the assembly time and speed may be improved to increase workability. Simultaneously, a low-voltage DC step motor may be used to reduce a risk of fire and electric shock, thereby increasing stability. Furthermore, since the magnet M is rotated around the center axis of the gear unit, a rotation signal may be sensed and outputted through a constant magnetic force. Thus, the merchantable quality of the driving device may be maximized.Type: ApplicationFiled: March 7, 2013Publication date: December 17, 2015Applicant: SCD CO., LTD.Inventor: Jin Ho LEE

Patent number: 8615929Abstract: A door opening/closing device for an ice dispenser is disclosed. The door opening/closing device includes a DC motor 1 which is rotated in forward and reverse directions, a 2-staged spur gear 3 meshed with a worm gear 2 installed on a driving shaft, a 3-staged spur gear 4 meshed with the 2-staged spur gear 3, and a fan-shaped output gear 5 meshed with the 3-staged spur gear 4 and rotated in forward and reverse directions by interconnection of the motor 1 and the gears 2, 3 and 4.

Patent number: 7135680Abstract: A focal plane array detector in a sensor for IR imaging. Pixel readout and analog to digital conversion is performed in an integrated circuit which includes the imaging array. The charge of each pixel is accumulated in a capacitor (16) and a digital to analog charge converter cancels this charge. A controller controls this charge converter providing the appropriate amount of charge. An analog to digital converter incorporating a comparator (92) switches the controller on/off. In some embodiment a programmable device external to the sensor participates in the control of the analog to digital converter. In a typical embodiment of the invention a cycle generator controls the charge output of the digital to analog converter. In a preferred embodiment the analog to digital converters are grouped wherein all such converters group operate simultaneously.Type: GrantFiled: May 21, 2003Date of Patent: November 14, 2006Assignee: Semi Conductor Devices (SCD) PartnershipInventors: Shimon Elkind, Amnon Adin

Patent number: 6312597Abstract: The invention relates to a wafer rinsing system for rinsing chemicals and particles off of wafers without introducing contaminants. The system reduces the particle count on wafers by filtering the water and the gas used during rinsing at the wet bench. The system includes a rinsing unit, a local water filter bank, a local gas filtering system, an H2O2 injection unit, an auxiliary chemical injection unit, and a controller for operating the other components. The water filter bank provides a multiple stage filtering system to eliminate particles without a substantial drop in water pressure. The H2O2 injection unit provides a local source of H2O2 to clean the filter and rinser and to provide a mechanism for controlling the formation of native oxide on the wafer during rinsing. The auxiliary chemical injection unit provides a chemical additive to the rinsing unit to enhance the wafer cleaning process. The gas filtering system provides clean gas to the rinsing unit and to the injection units.Type: GrantFiled: December 1, 1995Date of Patent: November 6, 2001Assignee: SCD Mountain View, Inc.Inventors: Raj Mohindra, Abhay K.
