  • Physical vapor deposition apparatus having a tapered chamber
    Patent number: 9920418
    Abstract: A physical vapor deposition (PVD) apparatus having a deposition chamber and a source chamber of minimal volume, which can be selectively isolated from each other by a various load-lock valves. Exemplary embodiments can include a tapered high vacuum chamber disposed between the deposition chamber and the source chamber. The pump down time of the apparatus can be reduced, as compared to conventional PVD systems, due to the combined reduced volume of the chambers. Coating uniformity can also be improved by spinning each part to be coated on its' own axis while selectively exposing to a deposition source with minimal particle generation.

  • Compensating rotor
    Patent number: 4163519
    Abstract: A 2:1 compensating rotor is used in a continuous-flow centrifuge system, thereby allowing the dynamic loading and unloading of biological suspensions and processing solutions in a "closed" fashion without resort to rotary seals. Improved high speed performance is obtained by utilization of an inherently symmetrical load sharing epicyclic reverted gear train. The effective lifetime of the component gears is increased due to the load sharing feature of the symmetrical epicyclic reverted gear train.
