  • Patent number: 8414279
    Abstract: An imprint apparatus molds resin dispensed on a shot region of a substrate with a mold and forms a pattern of resin on the shot region. The apparatus includes a mold stage configured to hold the mold, a substrate stage configured to hold the substrate, a drive mechanism configured to change a relative positional relationship between the mold stage and the substrate stage in an X-Y plane that defines a coordinate of the shot region and a Z-axis direction perpendicular to the X-Y plane, and a controller. The controller is configured to control the drive mechanism so that the mold and the shot region perform relative vibration, in the X-Y plane, with respect to a relative position where the mold and the shot region align, and a distance between the mold and the shot region decreases in the Z-axis direction in parallel with the vibration, and the resin is molded by the mold.

  • Patent number: 8361364
    Abstract: A method and apparatus for underwater pelletizing and subsequent drying of crystallizing polymers to crystallize the polymer pellets without subsequent heating is shown in FIG. 5. High velocity air or other inert gas is injected into the water and pellet slurry line (120) toward the dryer near the pelletizer exit (102) at a flow rate of from about 100 to about 175 m3/hour, or more. Such high-speed air movement forms a vapor mist with the water and significantly increases the speed of the pellets into and out of the dryer such that the polymer pellets leave the dryer with sufficient latent heat to cause self-crystallization within the pellets. A valve mechanism in the slurry line (150) after the gas injection further regulates the pellet residence time and a vibrating conveyor after the dryer helps the pellets to achieve the desired level of crystallinity and to avoid agglomeration.

  • Publication number: 20130009348
    Abstract: When a molded fabric body (X) is impregnated with a powder (K) of a predetermined material, there are performed a first step of dispersing the powder (K) in a liquid to prepare a slurry, and a second step of burying the molded fabric body (X) made of fiber bundles in the slurry and vibrating the slurry by use of a predetermined vibrator (M). Furthermore, in the second step, the vibrator (M) is moved along a surface of the molded fabric body (X). As a result, it is possible to improve the rate of impregnation of the powder (K) more than that in the conventional cases, irrespective of the shape of the molded fabric body (X).

    Abstract: An abrasive article can include an abrasive aggregate with the abrasive aggregate having a plurality of silicon carbide particles bonded together by a binder material. The binder material can include a vitreous phase material, a crystalline phase material, or both. In an embodiment, the crystalline phase material can include an aluminosilicate material. In a particular embodiment, abrasive aggregates can be formed from a mixture including silicon carbide particles, a binder material, and a liquid carrier. The mixture can be formed into a number of green granules that are vibrated and heated on a platen. In an illustrative embodiment, the green granules can then be heated to form abrasive aggregates.
