Publication number: 20100145513Abstract: A robotic positioning system that cooperates with a sensing system to correct robot motion is provided. The sensing system is decoupled from the sensors used conventionally to control the robot's motion, thereby providing repeatable detection of the robot's true position. In one embodiment, the positioning system includes a robot, a controller, a motor sensor and a decoupled sensor. The robot has at least one motor for manipulating a linkage controlling the displacement of a substrate support coupled thereto. The motor sensor is provides the controller with motor actuation information utilized to move the substrate support. The decoupled sensor provides information indicative of the true position the substrate support that may be utilized to correct the robot's motion.Type: ApplicationFiled: February 24, 2010Publication date: June 10, 2010Applicant: APPLIED MATERIALS, INC.Inventors: Pyongwon Yim, Satish Sundar, Vinay Shah, Mario David Silvetti, Douglas Kitajima, Venkatesh Babu, Visweswaren Sivaramakrishnan, Indrajit Lahiri, Surinder Bedi

Patent number: 7582167Abstract: In one embodiment, the invention is a guard ring for reducing particle entrapment along a moveable shaft of a substrate support. In one embodiment, the guard ring comprises a substantially annular guard ring positioned within a step formed in a sleeve that circumscribes the shaft. The guard ring is positioned to substantially seal a gap separating the shaft from the sleeve, so that the amount of particles and foreign matter that travel within or become trapped in the gap is substantially reduced. In another embodiment, a guard ring comprises a base portion having an inner perimeter and an outer perimeter, a first flange coupled to the inner perimeter, a second flange coupled to the outer perimeter, and a continuous channel separating the first flange from the second flange. The first flange is adapted to function as a spring that accommodates displacement of the shaft.Type: GrantFiled: October 3, 2007Date of Patent: September 1, 2009Assignee: Applied Materials, Inc.Inventors: Andrzej Kaszuba, Sophia M. Velastegui, Visweswaren Sivaramakrishnan, Pyongwon Yim, Mario David Silvetti, Tom K. Cho, Indrajit Lahiri, Surinder S. Bedi

Patent number: 6950282Abstract: A hard disk drive assembly that includes a device for limiting a movement of a head of a head gimbal assembly from a surface of a disk. The head is coupled to the disk and attached to a suspension of the head gimbal assembly. The invented device limits a distance that the head can move away from a surface of the disk. Limiting the distance that the head can move away from the surface of the disk, may reduce the impact force associated with the head slapping the disk, which may reduce damage associated with head slapping.Type: GrantFiled: October 7, 1998Date of Patent: September 27, 2005Assignee: Samsung Electronics Co., Ltd.Inventors: Pyongwon Yim, Hae Sung Kwon, Tho Pham, Hyung J.

Patent number: 6778352Abstract: The present invention is a shock absorption mechanism for reducing the damage experienced by disk drives, including damage caused by a magnetic head contacting the surface of a magnetic disk, as a result of impact or shock forces experienced by the disk drive. In general, the invention is a means for partially isolating a disk assembly and a related actuator assembly from other parts of the disk drive. In the preferred embodiment the shock absorption mechanism isolates the disk assembly and the actuator assembly from the outer frame of a housing containing the disk assembly and the actuator assembly by establishing a shock energy dissipation and absorption region between a pair of isolation plates holding the disk assembly and the actuation assembly, and other parts of the disk drive.Type: GrantFiled: December 28, 2000Date of Patent: August 17, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Yonkyu Byun, Sangeun Baek, Haesung Kwon, Pyongwon Yim

Patent number: 6545846Abstract: The present invention is a mechanism for making minute adjustments in the position of a read/write head for magnetically or optically reading from or writing to a data storage media. The head positioning mechanism (microactuator) will preferably be used in association with known disk storage actuation systems such as those typically used in current magnetic data storage devices such as hard disk drives, and optical data storage devices such as CDs. The microactuator comprises a slider support arm with a slider formed thereon, that is separated from an anchor structure by a gap. A pizoelectric element is positioned across the gap and is coupled at one end to the slider support arm, and at the other to the anchor structure. The anchor structure has greater resistance to bending than the slider support arm. Thus, when the piezoelectric element changes length, the slider support arm will tend to bend relative to the anchor structure, moving the slider on the slider support arm a controlled minute distance.Type: GrantFiled: March 31, 2000Date of Patent: April 8, 2003Inventors: Wonshik Chee, Haesung Kwon, Pyongwon Yim

Patent number: 6529349Abstract: A single latch that can secure an actuator arm when a hard disk drive has a clockwise rotational acceleration, or a counterclockwise rotational acceleration. The latch has a first end that can engage a first latch portion of the actuator arm when the disk drive has a clockwise rotational acceleration. The same latch also has a second end that can engage a second latch portion of the actuator arm when the disk drive has a counterclockwise rotational acceleration.Type: GrantFiled: November 1, 2000Date of Patent: March 4, 2003Assignee: Samsung Electronics CompanyInventors: Yongkyu Byun, Hae Sung Kwon, Shiao-Hua Chen, Pyongwon Yim

Patent number: 6417994Abstract: A swage mount plate that can be used to attach a suspension arm to an actuator arm of a hard disk drive. The swage mount plate may include a sleeve that can be inserted into corresponding swage openings of the suspension arm and an actuator beam of the actuator arm. The swage plate may include at least one flange that extends from said sleeve and becomes embedded into the actuator beam. The flange may increase the retention torque of the swage plate.Type: GrantFiled: April 22, 1999Date of Patent: July 9, 2002Assignee: Samsung Electronics, Co., Ltd.Inventors: Pyongwon Yim, Weonwoo Kim, Gregory Tran, George Wakatsuki
