摘要： A method of producing a light conducting fiber comprises the steps of providing a base member of an optical material such as glass or a synthetic glass-like material, depositing at least one optical material forming layer such as a glass forming layer or a synthetic glass-like material forming layer from a liquid phase on a surface of the base member and subsequently transforming each of the layers into a film of optical material such as a glass film or a synthetic glass-like film. The base member may be a glass tube and the optical material forming layers may be deposited on an interior surface and after the layers have been transformed into a film, the tube is collapsed into a rod and then subsequently drawn into a cladded light conducting fiber. In one embodiment of the invention, the base member is a rod and the layers are deposited on a surface of the rod which is subsequently drawn into a cladded light conducting fiber. In yet another embodiment of the invention, the base member is provided by drawing a core of an optical fiber and the method includes depositing the optical material forming layers on the core so that as the layers are transformed into the film of optical material, a cladded light conducting fiber will be produced.

摘要： Relatively pure Si (having less than about 1 ppm of detrimental impurities therein) is obtained from ordinary quartz sand by uniformly admixing such sand with suitable glass-forming materials, such as boron oxide and alkali-metal carbonates or oxides, melting such admixture to form a glass, annealing the glass so as to obtain a phase separation comprised of an SiO.sub.2 -- rich phase and an impurity-rich phase, extracting the impurity-rich phase via strong acid, such as nitric acid, washing and drying the remaining glass and reducing such glass with carbon-containing compounds, such as graphite, sucrose, starch, etc., in an electric arc. The so-obtained relatively pure silicon is suitable for fabrication into semiconductor components, such as solar cells.

摘要： A device for drawing a plurality of cladded light conducting fibers utilizing a double crucible having an inner crucible and an outer crucible with each of the crucibles having a bottom and receiving a melt of the respective material, and having nozzle pairs with the nozzle of the inner crucible being aligned axially with the nozzle of the outer crucible, the device including a device for gathering the pulled fibers to form a bundle and for coating the pulled cladded fibers characterized by the nozzles being exclusively arranged at points on the bottoms of their respective crucibles where the same temperature prevails for the glass melt present in the double crucibles. To accomplish this, the nozzles are located between and equal distance from the parallel boundary lines of the bottom of the inner crucible so that the melt drawn through the nozzle travels the same distance in all directions. The device for gathering is a coating cuvette, which is preferably formed of two longitudinal halves which can be moved transversely to the direction of movement of the fibers to facilitate threading the fibers into the cuvette.

摘要： A method and apparatus for producing a light conducting fiber having a core disposed in a loose fitting cladding tube characterized by a double crucible arrangement having a first crucible for a melt of the material for the cladding tube and a second crucible for the melt of the material of the core. The second crucible has an orifice of a given diameter and the first crucible has a ring-shaped orifice with an inner diameter greater than the given diameter of the orifice of the second crucible with the center of the ring-shaped orifice being arranged substantially on a central axis of the orifice of the second crucible so that a core drawn from the orifice of the second crucible is substantially concentrically disposed within the tube of material drawn from the ring-shaped orifice. In each embodiment of the apparatus, the first crucible is an annular crucible having a ring-shaped cross section and the second crucible is either disposed above the first crucible so that the core drawn from the second crucible passes through a hollow passage or is disposed in the central space either with spacing from the walls of the first crucible or with the inner wall of the first crucible forming the wall of the second crucible. Preferably, an inert gas is injected between the core and the tube to prevent collapsing of the tube during the drawing of the fiber.

摘要： Highly purified starting materials for the production of silicon suitable for fabrication of solar cells are produced via the carbo-thermal reduction process. A carbon-containing material with impurities therein, either by itself or admixed with glass bodies, which are attained from a melt of quartz sand and glass-forming additives formed into a fiber form and pulverized, is converted into a granulate form with the aid of a bonding agent. The resultant granulates are contacted with a hot inorganic acid, such as 3N HCl at about 90.degree. C., to extract substantially all impurities from the granulates, which can be in pellet or tablet form. The resultant purified pellets are then directly charged into an electrical arc furnace to yield solar-quality silicon. With this process, highly purified SiO.sub.2 and highly purified carbon are produced in a simple and cheap manner. The impurity level for boron, phosphorus and transition metal in these starting materials is less than about 10 ppm.
