Title: Innovations of Mohammad Mahbubul Ameen
Introduction
Mohammad Mahbubul Ameen is a notable inventor based in Campbell, CA (US). He holds a total of 11 patents that showcase his contributions to the field of engineering, particularly in the area of disc drive technology. His innovative designs have significantly impacted the efficiency and functionality of various mechanical components.
Latest Patents
Among his latest patents is the "Tapered Shaft Coating." This invention involves a component of a disc drive that features a coating of a predetermined length on its surface. The coating consists of at least two separate tapered regions applied in independent steps. Each tapered region has a length that is less than the predetermined length of the component surface. When the component is a shaft of a spindle motor, the ends of the shaft are masked before applying the tapered regions of coating. The thickness of the masks covering the shaft ends is varied to control the taper of the tapered regions.
Another significant patent is the "Dual Tapered Shaft for FDB Motor." This invention addresses motors with a journal that has one or more groove regions and a shaft for relative rotation in the journal. The design includes a dual tapered shaft, which is tapered by applying a wear-resistant coating opposite the groove regions. This coating introduces a shaft taper from near the top end and from near the bottom end towards the shaft middle, enhancing pumping efficiency. The coating can be applied using various processes, such as chemical vapor deposition or physical vapor deposition, to create a thickness gradient of coating material.
