Said pressure module further includes an adjustable spring between a top turntable and a bottom turntable, which are kinematically connected and driven by at least three pair of drive-pins and drive-bushes. Said pressure module is able to apply an adjustable pressure from bottom of the polishing fixture module. So the Fixture Module could not be floating in the pressure direction and maintain stationary when polishing machine is working. Two different quick-release mechanisms for a flexure polishing fixture module were invented for holding and releasing fiber ferrules or connectors during the polishing process controlled by sets of magnets. It's easy to work, and to protect the fixture flexure from the un-proper torque applied by different operators. The current invention is an improvement over our previous invention. | 09-25-2014 |
| 20150105005 | CHEMICAL MECHANICAL POLISHER WITH HUB ARMS MOUNTED - A chemical mechanical polishing system is provided. The chemical mechanical polishing system includes a platen, a load cup, a hub, a first polishing arm cantilevered from the hub and rotatable around the centerline of the hub between the platen and load cup, and a second polishing arm cantilevered from the hub and rotatable around the centerline of the hub between the platen and load cup the second arm rotatable independently from the hub. | 04-16-2015 |
| 20150290769 | ROTARY JOINT AND POLISHING APPARATUS - The invention suppresses generation of noises attributable to rotation of a rotary joint. | 10-15-2015 |
| 20160082381 | Hydro-filtration Unit with Sanding Heads - A motor, a reservoir, a recovery basket, an internal hose, an external hose, a power switch, baffle with injection nozzles and floats, a sanding head, an extended sanding head, and a corner sanding head comprises a hydro-filtration unit with a sanding heads for drywall work. The sanding heads may be used to sand drywall and simultaneously draw the dust out of the air as it is created through the sanding process. The hydro-filtration prevents dust from being released into the air. Within the reservoir, the internal hose connects at one end to the motor and at the other to the floating dust injector unit and the injection nozzles. The external hose connects the sanding heads to the motor. | 03-24-2016 |
| 20160082568 | POLISHING PAD, POLISHING APPARATUS AND METHOD FOR MANUFACTURING POLISHING PAD - The present invention relates to a polishing pad comprising a base sheet containing a restriction layer. The invention also relates to a polishing apparatus and a method for manufacturing a polishing pad. | 03-24-2016 |
