Filed: 1994-08-22
Abstract: PURPOSE: To prevent generation of vibration and abnormal noises by suppressing elastic deformation of a shaft when a maximum discharge rate condition is abruptly brought about, and suppressing vibration of the drive hub due to compression repulsion in the state of the maximum discharge rate. CONSTITUTION: A drive hub receiving surface 40c of a thrust flange 40 is arranged substantially perpendicularly to a shaft 5. In the case that a maximum discharge rate condition is brought about abruptly, an abutting portion 41c of a drive hub 41 abuts substantially perpendicularly to the drive hub receiving surface 40c of the thrust flange 40. Load in an axial direction of the shaft 5 and load perpendicular thereto are not applied to the shaft 5, which is thus little elastically deformed. In the state of the maximum discharge rate, the abutting portion 41c of the drive hub 41 abuts substantially perpendicularly to the drive hub receiving surface 40c of the thrust flange 40, so that compressive repulstion to be transmitted to the drive hub 41 is eliminated by the drive hub receiving surface 40c of the thrust flange 40. Vibration of the drive hub 41 is thus reduced.

Abstract: PURPOSE:To form a collector buried diffusion layer of a uniform thickness and contrive to make a layer fine, by making openings of fine patterns on an oxide film which is formed on a substrate. CONSTITUTION:An oxide film 10 is formed at the surface of a semiconductor substrate 1 and the oxide film 10 of a region where the collector buried diffusion layer 21 is formed has openings so that the fine openings 22 are spread all over the oxide film 10 by using the processes of photolithography and etching. After that, a coated insulating film 11 containing P, As, Sb, and the like is applied to the full face of the oxide film 10 and the openings 22. The coated insulating film 11 acts as a impurity diffusion source for forming the N-type collector buried layer 21. Since impurity elements are diffused thermally by the coated insulating film 11, heat-treatment is performed at a temperature around 800-1100 deg.C and the above diffusion layer 21 is formed in the substrate 1. In this way, the coated insulating film 11 is embedded in the fine openings 22 almost uniformly and as a result, all the supply of the impurity elements reaches the sane level at the openings of the oxide film 10 for impurity diffusion masks and then impurities diffuse uniformly through thermal diffusion and the amount of diffusion in the transverse direction becomes small.

Abstract: PURPOSE:To recover advantageously a useful metal such as iron in the molten copper matte discharged from a copper refining furnace by treating the molten matte by using carbon powder, flux, carrier gas, O2, etc., in a tap blown converter. CONSTITUTION:The molten matte discharged from a copper refining furnace is charged into the top and bottom blown converter 1. The coal powder, flux and if necessary iron ore-contg. powder are suspended respectively in the carrier gas and is blown together with O2 into the converter from a top blowing lance 3 and a bottom blowing tuyere 4 at the bottom of the converter. The iron oxide in the molten matte is reduced by the fixed carbon and reducing volatile gas in the coal powder to be blown from the hearth part. The combustible volatile component in the coal burns by contacting with O2 and contributes to the maintenance or increase of the temp. of the molten matte. On the other hand, the powder raw material and O2 blown from the lance 3 react with each other during the time when both and blown to the molten matte and in the case of using, for example, the iron ore-contg. powder, the iron oxide in the iron ore is reduced to iron by generated gaseous CO. The iron settles in the molten matte and the flux forms the molten slag to cover the surface of the molten iron.
