Patent number: 8777086Abstract: A bonding tool is adjusted to a desired operational position by viewing the bonding tool with an image-capturing device and displaying an image of the bonding tool as viewed by the image-capturing device onto a display screen. A corresponding image of a reference bonding tool showing the desired operational position of the bonding tool is superimposed onto the display screen and the position of the bonding tool is adjusted with an adjustment mechanism until the bonding tool as viewed by the image-capturing device is aligned with the superimposed image of the reference bonding tool.Type: GrantFiled: April 20, 2012Date of Patent: July 15, 2014Assignee: ASM Technology Singapore Pte. Ltd.Inventors: Jiang Wen Deng, Hei Lam Chang, Tim Wai Mak

Patent number: 8698492Abstract: Methods for testing for defects on magnetic media storage disks are provided. One such method includes dividing a surface of a magnetic media disk into a plurality of radial zones, dividing the disk surface into a plurality of concentric zones, thereby forming a preselected number (N) of wedge subsections for each of the concentric zones, scanning the disk surface for defects, counting the defects contained within each of the wedge subsections, summing the defects contained within two or more of the wedge subsections, comparing the summed defects with a preselected threshold, and determining, based on the comparison, a defect type of the disk.Type: GrantFiled: January 11, 2012Date of Patent: April 15, 2014Assignee: Western Digital Technologies, Inc.Inventors: Chee Wai Mak, Surasith Phongtharapat, Chalermchai Suchatpong

Patent number: 8483027Abstract: A disk drive is disclosed comprising a disk including a plurality of tracks, a head coupled to an actuator arm actuated over the disk, and control circuitry operable to first seek the head from a first track to a second track, read data from the second track to generate a first read signal, second seek the head from the second track to a third track, read data from the third track to generate a second read signal, third seek the head from the third track to a fourth track, and read data from the fourth track to generate a third read signal. The first, second, and third read signals are evaluated to qualify the disk drive, wherein the first, second, and third seeks are executed in proximity so as to excite the actuator arm with a jitter motion.Type: GrantFiled: May 25, 2011Date of Patent: July 9, 2013Assignee: Western Digital Technologies, Inc.Inventors: Chee Wai Mak, Chee Wai Lau, Suttisak Nilchim, Burin Jindasuay, Pramook Toworachot

Patent number: 6017694Abstract: Methods of screening for modulators of respiratory syncytial virus matrix protein interaction are described. A host cell carrying a nucleic acid sequence encoding RSV matrix protein or fragments of RSV matrix protein which can bind to RSV matrix protein is cultured and the RSV matrix protein or RSV fragments are expressed. The interaction of the expressed RSV matrix protein or fragments is measured. A test sample is then added to the expressed RSV matrix protein or fragments and the effect of the test sample on RSV matrix protein interaction is measured.Type: GrantFiled: December 19, 1997Date of Patent: January 25, 2000Assignee: American Cyanamid CompanyInventors: Paul Wai Mak, Bryan Mark O'Hara
