Title: Sheet production apparatus for removing a crystalline sheet from the surface of a melt using gas jets located above and below the crystalline sheet

Abstract

In one embodiment, a sheet production apparatus comprises a vessel configured to hold a melt of a material. A cooling plate is disposed proximate the melt and is configured to form a sheet of the material on the melt. A first gas jet is configured to direct a gas toward an edge of the vessel. A sheet of a material is translated horizontally on a surface of the melt and the sheet is removed from the melt. The first gas jet may be directed at the meniscus and may stabilize this meniscus or increase local pressure within the meniscus.

  • In one embodiment, a sheet production apparatus comprises a vessel configured to hold a melt of a material. A cooling plate is disposed proximate the melt and is configured to form a sheet of the material on the melt. A first gas jet is configured to direct a gas toward an edge of the vessel. A sheet of a material is translated horizontally on a surface of the melt and the sheet is removed from the melt. The first gas jet may be directed at the meniscus and may stabilize this meniscus or increase local pressure within the meniscus.
  • Embodiments related to sheet production are disclosed. A melt of a material is cooled to form a sheet of the material on the melt. The sheet is formed in a first region at a first sheet height. The sheet is translated to a second region such that it has a second sheet height higher than the first sheet height. The sheet is then separated from the melt. A seed wafer may be used to form the sheet.
  • An apparatus for removing heat comprises a heat sink having a cavity, and a synthetic jet stack comprising at least one synthetic jet mounted within the cavity. At least one rod and at least one engaging structure to provide a rigid positioning of the at least one synthetic jet with respect to the at least one rod. The synthetic jet comprises at least one orifice through which a fluid is ejected.

  • This patent describes apparatus for removing volatile contaminants located below ground level. It comprises: a withdrawal well terminating in a vadose zone above a below ground aquifer, a first conduit positioned in the withdrawal well and extending upwardly of ground level, first blower means positioned in flow communication along the first conduit for pumping air and volatile contaminants out of the vadose zone, a second conduit positioned in a first air injection well terminating in the aquifer, second blower means in flow communication along the second conduit for pumping atmospheric air into the vadose zone to urge the volatile contaminantsmore » toward the withdrawal well, and separator means positioned in flow communication along the second conduit downstream of the second blower means. The separator means is removing oxygen from the atmospheric air prior to pumping of deoxygenated air into the aquifer.« less
