Abstract: A silicon single crystal is grown by the CZ method. A silicon melt from which the crystal is grown is added with dopant such that the crystal has a resistivity of 0.025 to 0.08 ?cm. As well as the dopant, carbon is added to the silicon melt. The crystal is pulled in a hydrogen-bearing inert atmosphere.

Abstract: Method of carbonizing pitch-infiltrated fibrous annular preform by: infiltrating the preform with pitch; placing the pitch-infiltrated preform in a constraint fixture having an ejector base plate, an inner wall, an outer wall, and a top press plate; selecting the relative sizes of the preform and the constraint fixture so that a layer of inert friable material may be situated between the preform and walls of the constraint fixture; placing inert friable material (e.g., activated carbon) between the preform and the top, bottom, and walls of the constraint fixture; and subjecting the pitch-infiltrated fibrous preform to carbonization in the constraint fixture. The activated carbon or other inert friable material adsorbs pitch molecules that escape the preform during carbonization, which reduces problems with foaming.

Abstract: Carbon particles, such as, carbon fibrils and carbon nanotube molecules, are assembled into aligned fibers using processes derived from the processes used to manufacture optical fiber. More particularly, the carbon particles are embedded in glass, which is then drawn to align them. By aligned it is meant the axis along the longest dimension of each of the various particles in a local vicinity are substantially parallel.

Abstract: A system and method are described herein that control the environment (e.g., oxygen, hydrogen, humidity, temperature, gas flow rate, pressure) around one or more vessels in a glass manufacturing system. In the preferred embodiment, the system includes a closed-loop control system and a capsule that are used to control the level of hydrogen around the exterior (non glass contact surface) of the vessel(s) so as to suppress the formation of gaseous inclusions and surface blisters in glass sheets. In addition, the closed-loop control system and capsule can be used to help cool molten glass while the molten glass travels from one vessel to another vessel in the glass manufacturing system. Moreover, the closed-loop control system and capsule can be used to maintain an atmosphere with minimal oxygen around the vessel(s) so as to reduce the oxidation of precious metals on the vessel(s).

Abstract: Solutions permit or facilitate faster and/or easier processing involving loading or unloading of a work module into a process station. For example, the work module may be a processing tube or the like and the process station may be a heating station such as a tube furnace or the like. In one embodiment, the loading is from a single side of a process station. In one embodiment, the work module includes inlets and outlets for fluid flow, with both inlets and outlets being closer toward one side of the work module than the other side.

Abstract: In a process for granulating slag, from a blast furnace or a smelting reduction plant, in which a granule/water mixture formed during the granulation is fed to a granulation tank and then to a dewatering installation, in which the slag granules are dewatered. H2S-containing vapors and gases formed during the granulation are at least partially condensed by injection of water in a condensation space which is flow-connected to the granulation tank. H2S-containing residual gases are discharged from the compensation space below the water injection point, H2S is burnt.

Abstract: This invention relates to a method for manufacturing an artificial ultra-lightweight aggregate having a specific gravity of 0.8-0.9 using raw sewage sludge. According to the invention, raw sewage sludge and water-free waste are mixed into a blend having a water content that allows the optimal extrusion, whereby excellent ultra-lightweight aggregate which has low water absorption rate and, low slump loss can be produced. In addition, the collective treatment of waste and the mass production of recycled products are possible without addition of a drying process for raw sewage sludge, and thus excellent ultra-lightweight aggregate can be supplied at low cost.

Abstract: A method for feeding a flow of gas to a burner for manufacturing an optical fiber preform. The burner has a plurality of coaxial tubes, each two adjacent coaxial tubes defining an annular channel between themselves; an annular gas distribution chamber at one extremity of the annular channels and in fluid communication therewith, the annular distribution chamber being delimited in the radial direction by an inner and an outer surface. The flow of gas is introduced into the distribution chamber so that the direction of its radially outermost portion is tangential to the radially outer surface of the distribution chamber. The method allows obtaining a better gas velocity distribution in the annular channels.

Abstract: A clip to hold the film has a clip body, a flapper, a press slider and a rail mount. A pair of the press sliders is located in both sides of the flapper. A coil spring presses the press slider upward. A pair of entrance side film release members, provided in the tenter entrance, presses the press slider downward to press the lateral edge portions of the film by the press sliders. At the film hold position, the flapper rotates from a release position to a hold position to hold the film, and the flapper is kept at the hold position by a torsion spring. The flapper holds the film 26 after the press slider holds the lateral edge portions of the film, so the flapper can hold the film even when the lateral edge portions of the film are curled.
