  • Publication number: 20170358480
    Abstract: A device for holding and rotating a plate shaped article comprises a group of fixed pins and a group of pivot pins arranged along the circumference of the movable base in a manner that each pivot pin opposites a fixed pin, and also comprises magnetic bodies positioned within and outside two opposing sides of the pivot pins. Each of the pivot pins can be driven to rotate around its pivot back and forth under the magnetic repulsive force between two adjacent magnetic bodies, so as to release or clamp the plate shaped article. The present invention has advantages of simple structure, convenient and reliable action control, controllable clamping force and good compatibility with various processing chambers.

  • Patent number: 9580518
    Abstract: A method for fractionating dextrin, belonging to the technical field of food processing. In principle, the method for fractionating dextrin of the present invention is based on the fact that the dextrin is incompatible with polyethylene glycol in aqueous solution and a larger molecular weight of the dextrin results in more significant incompatibility with polyethylene glycol. Accordingly, the stepwise precipitation of dextrin components having a molecular weight from large to small may be realized by gradually increasing the concentration of polyethylene glycol by gradually adding polyethylene glycol to dextrin in aqueous solution.

  • Publication number: 20140307056
    Abstract: The subject disclosure is directed towards a framework that is configured to allow different background-foreground segmentation modalities to contribute towards segmentation. In one aspect, pixels are processed based upon RGB background separation, chroma keying, IR background separation, current depth versus background depth and current depth versus threshold background depth modalities. Each modality may contribute as a factor that the framework combines to determine a probability as to whether a pixel is foreground or background. The probabilities are fed into a global segmentation framework to obtain a segmented image.

  • Patent number: 8834582
    Abstract: The present invention provides an apparatus for manufacturing semiconductor wafer comprising at least two manipulators, at least one set of chemical gas/liquid distribution unit and an air circulating and filtering unit. The air circulating and filtering unit is separated into three regions, including the front region, the middle region, and the side region, which are controlled by respective control electric motors to achieve uniform air flow and uniform pressure in the respective regions. The cleaning degree in the internal of the apparatus can be improved by the regional control of the air circulating and filtering unit; the wafer transport efficiency can be enhanced by the double-armed manipulators having multiple degrees of freedom; and the product yield per unit area can be increased by the chemical gas/liquid distribution unit providing stable and uniform gas/liquid flow and pressure.
