Title: Nozzle for pouring molten steel
Inventor: UESUGI HIROYUKI
IPC: B22D11/10
Filed: 1980-04-28
Abstract: PURPOSE:To effectively prevent the closing of a nozzle hole through static pouring other than a bubbling method by flowing molten steel into a nozzle body, the top part thereof is provided with a spacing part encircling the nozzle hole, and forming turbulence by providing a small-diameter part in the nozzle hole. CONSTITUTION:The large-diameter part 1 in the top part of the nozzle body is made into double tube constructon, of which the outside tube part 3 is formed with a hollow hole part 4 of a two-step shape, and the inside tube part 2 is joined to the lower step hollow hole 4a. This puts the remaining space 5 of the upper-step hollow hole part 4b of a large diameter into the state of enclosing the upper half part of the inside tube part 2. The smallest hole diameter part 6 is formed in the upper part of the nozzle hole in the part 2. This nozzle shape contributes to the formation of turbulence in molten steel flow owing to the abrupt change in the nozzle hole diameter by the smallest hole diameter part 6 in the upper part of the nozzle where the solidification of the molten steel flow is liable to occur. In addition, the part 6 is kept heated at all times by the heat of the molten steel flowed into the remaining space 6; hence, the solidification and deposition of the molten steel are prevented.

Title: Diffusion of impurities
Inventor: KANEKO HIROSHI
IPC: H01L21/225
Filed: 1981-04-17
Abstract: PURPOSE:To eliminate the defects generating from the diffusion of impurities by a method wherein, after polycrystalline Si has been provided on an Si surface, impurities are diffused in vapor-phase into the Si. CONSTITUTION:An SiO2 16 of approximately 1mum in thickness is provided in advance on an N type Si wafer 2, and a polycrystalline Si film 36 is deposited on the SiO2 film in a vacuum using SiH4. At this time, the surface of the wafer 2 is contaminated with the swarf 17 of quartz ampoule and the particles 37 wherein diffusion impurities Ga and Si, which is doped in advance, are alloyed. Therefore, after the above has been thoroughly boiled up using aqua regia, it is washed clean with pure water, processed for thirty minutues by the mixed acid of HF+NHO3+H2O, and the swarf 17 and the Ga particles 37 are completely removed together with the polycrystalline Si 36. Accordingly, the front of a P type diffusion layer 22 can be made uniform even after driving. If the predeposition of diffusion impurities is performed at a high temperature for a long time, the density of defects increases, and the density of defects is reduced in proportion to the increase in the thickness of the polycrystalline Si film. Also, the yield rate of an element is improved remarkably when the optimum thickness is selected for the polycrystalline Si film.
