  • Publication number: 20220097182
    Abstract: A method for processing a mortise of a small-size superalloy turbine disk using laser shock peening A laser shock peening (LSP) parameter of a laser shock peening (LSP) robot is designed. A spatial data of a motion trajectory of the LSP robot for a laser shock peening area of mortise teeth of the first mortise is found and recorded using a robot simulation system software to generate a trajectory program of the robot for the first mortise. Then a rotation program of an end of an arm of the LSP robot is written according to an included angle between two adjacent mortises to generate a trajectory program of the robot for all mortises of the turbine disk. Finally, the turbine disk is processed by laser shock peening.

  • Patent number: 10449958
    Abstract: A computer system receives data sets for a driving maneuver at a location, such as data regarding a state of a vehicle, an external environment indicated by external sensors, and user feedback regarding the driving maneuver. Data sets may be collected from users having various demographic and behavioral attributes. Users may be selected using design of experiment (DOE) algorithms to cover a wide range of possible combinations. A stochastic response surface model (SRSM) is generated that relates sensor data (vehicle state and environmental) to user feedback regarding safety and comfort. The SRSM may be generated using Gaussian process regression (GPR) in order to model uncertainty. The SRSM is then used to generate a control model using an optimization under uncertainty (OUU) algorithm.

  • Publication number: 20090298388
    Abstract: A novel polisher for chemical mechanical planarization process is described. The polisher design can have many variations. For process development and consumable evaluation, the CMP process can be performed on a single die or a section of the wafer. The size of testing wafer can be as small as 2? and as large as 18?. Furthermore, several variations can characterize the slurry for their static etch rate, dynamic etch rate, material removal rate, and viscosity in a single experiment. For production level wafer processing, Chemical Mechanical Polishing of all dies on the wafer surface is achieved by using multi-armed polishing heads or a single polishing head with small piece of a pad at the bottom of the head. The within wafer uniformity can be easily controlled and the equipment can be easily scaled up or down. This inventive design may translate to significant cost reduction for wafer processing at production level as well as evaluation of consumables at research and development level.

  • Publication number: 20040092102
    Abstract: A chemical mechanical polishing (CMP) formulation and method for using the same. The composition is useful for polishing semiconductor substrates, and particularly substrate surfaces containing copper, tungsten, or alloys of the same. The CMP formulation may contain a copolymer enhancement agent such as a Pluronics® compound, and/or a vesicle encapsulating agent, as well as an active agent that is chemically reactive with the substrate to enhance polishing performance. The active agent may be a bifunctional compound that is capable of functioning as both a passivating agent and a complexing agent to achieve an optimum rate of passivation and oxidation on the substrate surface. An active agent can also take the form of an oxidation activator, such as a metal ion, encapsulated in a vesicle or micelle, that is released with applied pressure to accelerate the removal process and improve planarization efficiency.

  • Patent number: 4986997
    Abstract: A stepwise process for the treatment of wheat as an adjunct to conventional milling is provided which permits recovery of substantial quantities of wheat embryo and scutellum, to thereby increase the yield of premium germ while enhancing the storability of the resultant flour by virtue of removal of the high oil germ fractions. The process involves initial temperating of wheat followed by impact scouring to remove intact embryo; thereupon, the deembryonated wheat is subjected to a second tempering step prior to milling. The break system of the mill is appropriately modified by judicious selection of milling gap so as to permit recovery of intact scutellum, especially from hard red winter wheat.
