Inventor: WILSON THOMAS NOELL
IPC: B21C49/00
Filed: 1989-12-23
Abstract: In a continuous casting and rod rolling system, the production rate is generally limited by the capacity of the slowest element. The present invention is directed to changes in the rod coiling station portion of the system, and particularly to modifications to the flyer tube (40) and loop forming portions (44) which enable higher production capacity. According to these changes, the prior art flyer tube (31) is shortened to eliminate the constant radius end portion thereof, and the circle forming function is performed by adding an annular cylinder (44) coaxial with the flyer tube (40) axis to shape the rod (22) into a nearly perfect circle (35). The flyer tube (40) according to the invention has a continuously changing angular relationship from its axis; the curved longitudinal path of the tube (40) redirects rod (22) from its vertical path to discharge the rod (22) from the flyer tube (40) in a generally horizontally direction. The circular loop forming cylinder (44) forms the rod (22) into circular loops (35) which fall freely from the cylinder (44) onto a turntable surface (36).

Abstract: A distortion compensation circuit for power amplifier (135-1,135-N) producing a prescribed distortion component receives an input signal (S) having at least one carrier therein in a prescribed frequency range. The input signal (S) is applied to a first circuit path having an amplifier (105) that produces an amplified signal with the prescribed distortion component and to a second circuit path (104) that delays the input signal without distortion. The output signals of the first and second circuit paths are combined in a first combiner (117) to form a signal representative of the prescribed distortion component. A second combiner (115) forms a signal having an amplified input signal component and inverted phase prescribed distortion component responsive to the output of the first combiner (117) and the output the first circuit path. To eliminate signals other than the distortion component from the first combiner (117), the prescribed frequency range is scanned to detect a carrier signal and the amplitude and phase of the signal in the second circuit path is modified to remove the detected carrier from the output of the first combiner (117). Remaining distortion in the power amplifier (135-1, 135-N) output is removed by scanning the prescribed frequency range to detect an intermodulation product signal and modifying the amplitude and phase of the first combiner output (117) to minimize the detected intermodulation product signal.

Abstract: On a p⁻ substrate (31), an n⁻ epitaxial layer (32) is surrounded and isolated by a p well (33). At the surface of the n⁻ epitaxial layer (32), a p floating region (35) is provided in the vicinity of the p well (33) on which a sense electrode (SEN) is provided. An insulation film (36) and a conductive film (37) are formed on the n⁻ epitaxial layer (32) between the p well (33) and the p floating region (35) to overlap them. The conductive film (37) and the p floating region (35) serve as a composite field plate, which makes it difficult for the surface electric field distribution to be influenced by the state of electric charge at the surface and relieves the surface electric field by expanding the depletion layer, which extends from the pn junction between the n⁻ epitaxial layer (32) and the p well (33) into the n⁻ epitaxial layer (32) in current blocking state, toward the centre of the n⁻ epitaxial layer (32). The potential of the p floating region (35) is determined by capacity coupling in the current blocking state and thus the sense voltage characteristic monitored through the sense electrode (SEN) is smooth.

Abstract: A simple, operationally reliable and economic process is described for decaffeinating green coffee, which ensures a high degree of decaffeination, avoids denaturation of further constituents of the green coffee and permits isolation of the caffeine. In this process, green coffee beans, optionally moistened to 20% by weight to 40% by weight, are first extracted with a carbon dioxide-saturated liquid solvent, preferably water, at a temperature of 20 DEG C to 110 DEG C and at a pressure of 30 bar to 300 bar and, after reducing the pressure to 1 bar to 10 bar, are rinsed with the liquid solvent. The liquid phase loaded with the green coffee constituents including caffeine is decaffeinated in a device provided downstream by treatment with supercritical carbon dioxide and is again saturated with CO2. The caffeine is washed out of the supercritical CO2 phase with water and is isolated in pure crystalline form. <IMAGE>

Abstract: This invention is directed to the fabrication of semiconductor devices, especially those comprising III-V and II-VI compound semiconductor materials, and involves annealing, especially Rapid Thermal Annealing (RTA), of semiconductor wafers, especially those implanted with a dopant(s). The invention is also concerned with a black-box implement used in combination with the RTA. The process includes enclosing a wafer (1) to be annealed within a "black-box" comprising components (10,11,12) of a black body material and subjecting the black box with the wafer therein to an RTA. In a preferred embodiment the RTA comprises (a) a pre-anneal step which includes heating to a temperature and for a period sufficient to preheat the wafer so as to reduce thermal shock due to a main annealing step, (b) the main annealing step being at a temperature and for a period sufficient to remove damage caused to said surface by the dopant implantation and to activate implanted dopant, and (c) a post-anneal step carried out at a temperature and for a period sufficient to relieve stresses which may result from the main annealing step. The combined use of the RTA and the black box leads to wafers substantially free of slip lines and with reproducibly high mobilities and uniform activation.
