  • Patent number: 10226567
    Abstract: Method and apparatus for centrifugal blood component separation including temperature sensing in each of a plurality of separation cells. The temperature of unit of bloods over time is recorded. If the temperature of any of the units exceeds a pre-determined maximum, portions of the blood separation device may be cooled. A controller may determine which of the units to process first, generally proceeding from the warmest unit to the coolest. The order of unit processing may be changed during processing. The detected temperature may be used to calibrate a pressure sensor used to predict the volume of a component separated from a composite fluid by predicting the volume of the composite fluid from sensed pressure and predicting the volume of other separated components from sensed movement of the other components to collection bags.

  • Patent number: 8556792
    Abstract: A fraction collector, sample drier that automatically re-fills sample contains is described. Profiles of RPM and/or back EMF decays as a rotating but unpowered rotor comes to a stop are generated. The profiles may be generated for rotors with full, partially filled and empty sample containers. During a drying operation as the non-volatile samples are collected by evaporating the liquids more sample may be loaded while the rotor is spinning. The operation is to unpower the mechanism and measure the decay profile of PPM and/or EMF over time. A threshold may be set so that the lighter rotor will stop more quickly, and if the threshold is crossed the mechanism will load more sample into the containers.

    Abstract: After rinsing, a liquid mixture (IPA+DIW) is supplied to a substrate surface while rotating a substrate at a first rotating velocity which is relatively high to thereby replace the rinsing liquid adhering to the substrate surface with the liquid mixture. In this way, the rinsing liquid adhering to the gaps between the patterns formed on the substrate surface is replaced with the liquid mixture. Subsequently, DIW is supplied to the substrate surface in a condition that the rotation of the substrate is stopped or that the substrate is rotated at a second rotating velocity which is relatively low to thereby form a puddle-like liquid layer with DIW. In this way, the liquid mixture of the surface layer part is removed from the substrate surface while leaving almost all the liquid mixture adhering to the gaps between the patterns. After that, the liquid layer is removed from the substrate surface to thereby dry the substrate surface.

    Abstract: Small crystals are made by mixing a solution of a desired substance with an anti-solvent in a fluidic vortex mixer in which the residence time is less than 1s, for example 10 ms. The liquid within the fluidic vortex mixer (12) is subjected to high intensity ultrasound from a transducer (20, 22). The solution very rapidly becomes supersaturated, and the ultrasound can induce a very large number of nuclei for crystal growth. Small crystals, for example less than 5 ?m, are formed. The resulting suspension is treated so as to add or remove ingredients, and then spray dried using an atomizer tuned to create small droplets in such a way that each droplet should contain not more than one crystal. Crystal agglomeration is hence prevented.

  • Patent number: 7171762
    Abstract: A self-cleaning centrifugal pellet dryer and method for removing surface moisture from pellets and enabling complete removal of all pellets from the dryer after each drying cycle. By eliminating dried pellets retained in the dryer, contamination of different type pellets dried during a subsequent drying cycle is avoided. Air and water under pressure are discharged toward various pellet hang-up points in the dryer to remove retained pellets.

  • Patent number: 7127828
    Abstract: A rotor that may be used by itself or in a processing machine for processing semiconductor wafers includes two pairs of combs. A lock down mechanism has a lock bar, temporarily engaged and moved by a loading/unloading robot, drives a retainer against the edges of the wafers, to better hold them in place during processing. Contamination via generation of particles is reduced. Combs on the rotor have a resilient strip. The lower edges of the wafers compress slightly into or deflect the resilient strip, when urged into place by the lock down mechanism.

  • Patent number: 7100304
    Abstract: An apparatus for drying a generally flat substrate that has been cleaned has a rotatable support for supporting the substrate, a substrate drying assembly, and a controller. The substrate drying assembly includes a substrate drying assembly support arm, an outlet for applying liquid to an upper surface of the substrate, and an outlet for applying a drying vapor to the upper surface of the substrate. The substrate drying assembly is configured to position the liquid applying outlet and to position the vapor applying outlet above a portion of the substrate. The controller causes the substrate drying assembly to be retracted over the upper surface of the substrate at a faster rate near a center of the substrate than near a periphery of the substrate.

  • Patent number: 7080463
    Abstract: A salad spinner and mixer may be made from two substantially identical transparent bowls that can be joined together at their rims to define a chamber; two substantially identical colanders that can be joined together at their rims and received within the chamber; and a bifurcated base that has a spindle on each of two parallel upstanding portions. When the spindles are received within dimples on the bottoms of the bowls, the bowl and colander assembly can be spun about an axis defined by the spindles to remove water from the salad ingredients. The bowl assembly, used without the colanders, can also be use to mix salad dressing with salad ingredients. The resultant salad can be served in one of the bowls. Moreover, the bifurcated base can serve as a napkin holder.

  • Patent number: 7056392
    Abstract: A wafer chuck is configured to hold a wafer efficiently for spin process cleaning of wafer edges and back sides. A first group of retractable tips extend to hold the wafer during a first portion of the cleaning period. A second group of retractable tips extend to hold the wafer during a second portion of the cleaning period. Residues left between the tips and the wafer edge areas during the first portion of the cleaning period are removed during the second portion. The change from the first group of tips to the second group of tips occurs while the wafer is rotating.

  • Patent number: 6993855
    Abstract: The present invention provides: a method for drying compacts containing water so as not to cause explosion and powdering; a method for reducing the compacts after being dried with great efficiency in a rotary-hearth-type reducing furnace; and a rotary-hearth-type metal reducing furnace. In the present invention, when compacts comprising powder containing metal oxide and carbon are dried, the critical value of a water evaporation rate, beyond which explosion occurs, is determined from the size and porosity of the compacts, then the water evaporation rate is controlled to a value not exceeding the critical value and, by so doing, the increase in the internal pressure of the compacts caused by the generation of water vapor is prevented. By the method, the explosion and cracking of the compacts are prevented.

  • Patent number: 6754975
    Abstract: An apparatus for attenuating physical damage to a substrate, along with an attendant method, comprises as a first component a base plate having defined therein a location for receiving a substrate cassette. The apparatus also comprises a substrate retainer movably attached to the base plate such that when the substrate cassette having a substrate contained therein is positioned on the base plate at the location for receiving the substrate cassette, and the substrate is subjected to a mechanical force, the substrate retainer moves such as to retain the substrate within the substrate cassette with a retaining force. Both the apparatus and the method are particularly applicable for attenuating damage to a substrate when spin-drying the substrate.
