  • Publication number: 20230417293
    Abstract: A wet multi-plate clutch includes a plate carrier with a pair of fluid passage openings and a friction plate rotationally fixed and axially displaceable relative to the plate carrier. The friction plate has a carrier element and a pair friction pads fastened to the carrier element and delimiting a groove. The groove includes a groove geometrical center line. The groove geometrical center line may extend radially through a one of the pair of fluid passage openings, or it may extend radially between the pair of fluid passage openings. If the groove geometrical center line extend radially between the pair of fluid passage openings, one of the pair of friction pads may include a pad geometrical center line extending along a radial extent through a one of the pair of fluid passage openings.

  • Patent number: 9685342
    Abstract: Wafer processing apparatuses and methods of operating the same are provided herein. In an embodiment, a wafer processing apparatus includes a rotatable platen that has the capacity to support a polishing pad on a pad mounting surface of the rotatable platen. A drive assembly is coupled to the rotatable platen and has the capacity to rotate the rotatable platen. A polishing head is coupled to a head actuator. The polishing head is disposed adjacent to and over a first portion of the pad mounting surface and the polishing head is movable relative to the pad mounting surface by the head actuator. An optical sensor has a vision field including a second portion of the pad mounting surface. The first portion and the second portion of the pad mounting surface are at least partially offset. A control unit is operatively connected to the drive assembly and the head actuator.

  • Publication number: 20150152518
    Abstract: A method for centrifugal reprocessing of a solids-containing emulsion formed during the hydrometallurgical recovery of a metal involves performing the reprocessing in at least one decanter to form a first lighter liquid phase, a second liquid phase, and a solids phase. An actual value of the density of the first liquid phase is determined, the actual value is compared with a desired value for the density of the first liquid phase, and the outlet pressure of the first liquid phase is set in dependence upon the determined actual value/desired value comparison.

  • Publication number: 20040123951
    Abstract: A retaining member for a polishing head in a CMP apparatus comprises a bottom surface with silicon carbide. Due to the superior characteristics of silicon carbide, a low wear rate of the retaining member is secured, wherein, additionally, accumulation of electrostatic charges is substantially avoided due to the conductivity of silicon carbide. Consequently, cost of ownership is reduced, while at the same time process stability over a large number of substrates is increased.
