Title: Boat for liquid-phase epitaxial growth
Inventor: HANEKI YOSHIAKI
IPC: H01L21/208
Filed: 1991-01-07
Abstract: PURPOSE:To prevent rotation of a substrate when a slider is slid and enable a liquid solution to be separated from the substrate completely by providing an opening for housing the liquid solution so that it is in contact with the substrate in parallel to a sliding direction of a circular semiconductor crystal substrate at an outside of the opening which houses the liquid solution of a liquid solution well. CONSTITUTION:Another liquid solution well opening 7 is provided outside a liquid solution opening 2 of a boat for liquid-phase epitaxial growth so that a substrate 4 is in contact being parallel to the sliding direction for performing liquid-phase epitaxial growth. Then, an epitaxial layer is allowed to grow at another portion outside a portion where the epitaxial layer is allowed to grow originally. This epitaxial layer is allowed to grow on the substrate 4 in a form which is in parallel to the sliding direction by the shape of the liquid solution well opening 7. Therefore, the substrate 4 is fixed in the sliding direction and no rotation of the substrate 4 occurs even if the substrate 4 is rotated due to outer force at the time of sliding a slider.

Title: Method for recovering valuable metal from waste catalyst
Inventor: SHIMAUCHI HISAAKI
IPC: C22B34/34
Filed: 1993-02-26
Abstract: PURPOSE:To easily separate and recover valuable metals in a waste catalyst using alumina as the carrier, such as No, Ni, Co, V, Al, etc., in high yields by calcining the waste catalyst, dissolving it into sulfuric acid together with the catalytic metals to be dissolved and subjecting the resulting solution to extraction sulfiding and adsorption successively. CONSTITUTION:The waste catalyst using the carrier consisting essentially of alumina is defatted and calcined at 400 to 1000 deg.c. The resulting calcined material is dissolved into sulfuric acid together with the catalytic metals to be dissolved to obtain the original solution to be extracted. This original solution is extracted with an organic Mo extractant and Mo is recovered from the Mo contg. organic phase of the Mo extractant. Then the residual solution resulting from the Mo extraction is extracted with an organic V extractant and V is recovered from the V contg. organic phase of the V extractant by stripping it out. Further the residual solution resulting from the V extraction is brought into contact with gaseous H2S and the Ni and Co in the solution are recovered as their sulfides. The minute amounts of Ni and Co in the finally recovered solution are adsorbed and recovered with a chelate resin to obtain a high purity aluminum sulfate solution. Then the Ni and Co adsorbed on the chelate resin are liberated from it with sulfuric acid and the liberated solution is repeatedly returned to the above reduction and dissolution processes.
