Latest Patents

Among his notable inventions, the "Method for forming a dual actuator pivot" is particularly remarkable. This method eliminates the need for adhesive bonding, thereby minimizing assembly time. It involves an upper sleeve assembly that includes upper and lower ball bearings press-fitted therein, along with a lower sleeve assembly showcasing a similar design. The innovation allows for precise tuning of a predetermined axial load to select a desired resonance frequency for both actuator bearing assemblies, which can be achieved through strategic chilling or heating of the components during assembly.

Another significant patent is the "Pivot bearing assembly for compensating for disk drive actuator tilt." This design employs a shaft to support two actuators, incorporating a pivot assembly that compensates for tilting due to shaft bending during operational movements. The use of two types of bearings with differing stiffness enhances performance by allowing for adjustable boundary conditions that effectively counteract shaft bending.
