Patent number: 7513410Abstract: An air bearing gap control arrangement for injection molded solder filler heads. Also provided is a method of providing for a gap control for injection molded solder filler heads utilizing an air bearing arrangement. Provided is a C-ring seal, at the lower or dispensing region of the solder filler head structure, wherein the C-shape is open at the leading edge thereof. Hereby, a prevalent leading edge gap is tightly controlled by means of pressurized air in order to form an air bearing. Downstream of this leading edge is the molten solder, which is contained within a very narrow gap height between the solder filler head and the mold. As the solder fills the pits or recesses which are formed in the mold surface, air will rush out or be displaced from the pits towards the air bearing and is then expelled, while the deposited solder remains in place.Type: GrantFiled: June 11, 2007Date of Patent: April 7, 2009Assignee: International Business Machines CorporationInventors: Glen N. Biggs, Timothy J. Chainer, John P. Karidis, Dennis G. Manzer, Christopher L. Tessler

Patent number: 7511913Abstract: Embodiments of the present invention provide an approach in the time domain, instead of the frequency domain, for analyzing and correcting for radial propagation instability in servo-writing. In one embodiment, a system for controlling a read/write head of a disk drive to correct propagation errors during self-servo writing on a disk comprises a time-domain based controller to provide closed-loop feedback control to an actuator for moving the read/write head, the controller including a state observer. The controller is configured to measure read head position information of the read/write head on the disk; provide the measured read head position information to the state observer which produces feedback variables for feedback control of the read/write head, the feedback variables being weighted by feedback gains which have been determined a prior; and apply the weighted feedback variables to provide the closed-loop feedback control to the actuator for moving the read/write head.Type: GrantFiled: April 20, 2006Date of Patent: March 31, 2009Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventor: Dennis G.

Patent number: 4618808Abstract: Using as an actuator a stepper motor operated in a position-sensed closed loop mode via an electronic commutator by position and anomaly corrected motion control signals provided by a programmable logic array and by a microprocessor, provides a precision power positioner. The correct enabling of the motor coils, based on position sensing of the motor phase, using electronic commutation for the stepper motor, transforms the problem of enabling coil selection to the programmable logic array, which by its logic provides a simplified operating control as a function of present armature position feedback, and by a microprocessor corrects for anomalies such as temperature rise, square-law, and phase increase as a function of position desired and present armature position feedback signals, and thus provides high positional accuracy, high speed and force (torque) control independent of the motor cardinal step positions.Type: GrantFiled: January 30, 1985Date of Patent: October 21, 1986Assignee: International Business Machines CorporationInventors: Jehuda Ish-Shalom, Leonard A.
