| 117209000 | Including solid member shaping means other than seed or product (e.g., EDFG die) | 8 |
| 20080282972 | Method and mould for casting articles with a pre-determined crytalline orientation - Previously a number of techniques have been used in order to form single crystal or pre-determined crystallography components and articles. Each one of these techniques has its own particular problems, including susceptibility to error. By utilisation of a bi-crystal experiment to determine melt-back length LM and by consideration of the ingress distance d from potential initiation nucleation points on a perimeter of a seed crystal, it is possible to determine a maximum ingress length d. By ensuring that the maximum ingress length d is less than or equal to a seed crystal diameter R, it is possible to project locus from potential nucleation points C | 11-20-2008 |
| 20140182512 | CRYSTAL GROWTH APPARATUS - A crystal growth apparatus includes a first housing, a second housing and a controller received in the second housing. The first housing includes a first main body and defines a growth chamber in the first main body. The second housing includes a second main body and a pulling rod. The second main body defines a transmission chamber and a cooling chamber. The pulling rod is mounted in the transmission chamber, and a first seed rod is mounted on the pulling rod. The controller includes a transmission member and a pair of partition assemblies. The second housing includes a separating sheet and a second seed rod. The separating sheet separates the transmission chamber from the growth chamber. The second seed rod is mounted in the cooling chamber. The pair of partition assemblies move enabling the cooling chamber to communicate with the transmission chamber, such that the transmission member exchanges seed rods. | 07-03-2014 |
| 20140202379 | CRUCIBLES MADE WITH THE COLD FORM PROCESS - A crucible for growing crystals, the crucible being formed from Molybdenum and Rhenium. A crucible for growing crystals, the crucible being formed from a metal selected from Group V of the Periodic Table of the Elements. A crucible for growing crystals, the crucible comprising a body and a layer formed on at least a portion of the body, the layer being formed out of Molybdenum. | 07-24-2014 |
| 117211000 | Including means forming a flat shape (e.g., ribbon) | 5 |
| 20140083353 | PLANE ORIENTATION OF CRYSTALLINE STRUCTURES - Systems and method for creating crystalline parts having a desired primary and secondary crystallographic orientations are provided. One embodiment may take the form of a method of manufacturing a part having a crystalline structure. The method includes melting aluminum oxide and drawing the melted aluminum oxide up a slit. Additionally, the method includes orienting the seed crystal relative to a growth apparatus such that a crystalline structure grows having a desired primary plane and a desired secondary plane orientation. Moreover, the method includes pulling the crystal as it forms to create a ribbon shaped crystalline structure and cutting a part from the crystalline structure. | 03-27-2014 |
| 20140150716 | MELT FIXTURE INCLUDING THERMAL SHIELDS HAVING A STEPPED CONFIGURATION - Various single crystals are disclosed including sapphire. The single crystals have desirable geometric properties, including a width not less than about 15 cm and the thickness is not less than about 0.5 cm. The single crystal may also have other features, such as a maximum thickness variation, and as-formed crystals may have a generally symmetrical neck portion, particularly related to the transition from the neck to the main body of the crystal. Methods and for forming such crystals and an apparatus for carrying out the methods are disclosed as well. | 06-05-2014 |
| 117212000 | Pulling includes a horizontal component | 3 |
| 20130263777 | APPARATUS FOR MANUFACTURING SILICON SUBSTRATE - There is disclosed an apparatus for manufacturing a silicon substrate including a crucible part, a molding part extended from an outlet of the crucible part, the molding part comprising a molding space where a silicon substrate is formed, and a dummy bar inserted in the molding space from a predetermined portion of the molding part, wherein the dummy bar is formed of a single-crystalline material. | 10-10-2013 |
| 20140209016 | REMOVING A SHEET FROM THE SURFACE OF A MELT USING GAS JETS - 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. | 07-31-2014 |
| 20150322590 | APPARATUS FOR PROCESSING A MELT - An apparatus for processing a melt may include a crucible configured to contain the melt, where the melt has an exposed surface that is separated from a floor of the crucible by a first distance. The apparatus may further include a submerged heater comprising a heating element and a shell disposed between the heating element and the melt, wherein the heating element does not contact the melt. The heating element may be disposed at a second distance with respect to the exposed surface of the melt that is less than the first distance. | 11-12-2015 |
