IPC: H01M4/06
Filed: 1986-06-13
Abstract: PURPOSE:To prevent the particle interface corrosion at the spotwelded part of the collector of a cylindrical lithium cell with a spiral positive electrode plates, and to improve the high temperature durability, by applying a porous stainless steel thin plate of a specific ferrite family as the separator. CONSTITUTION:For a collector of sheet-form thin positive electrode plates 3, is applied a ferrite family stainless steel thin plate including 16 to 19wt% of Cr, 1.8 to 2.5wt% of Mo, and 0.5wt% of Nb plus Ta. The Cr produces an inactive layer over the surface primarily, to maintain the anticorrosion property, Mo has an anticorrosion effect about three times that of Cr, while Nb and Ta have the affinity with the residual C and N in the steel which is utilized to make NbC and TaN in the metallic crystals to fix such elements and to prevent the separation of C and N at the particle interfaces of the crystals, the socalled particle interface corrosion being prevented. Therefore, the C and N separated at the crystal particle interfaces are prevented from reacting with the Cr, destroying and negating the inactive layer of Cr, and deteriorating the anticorrosion property.

Abstract: PURPOSE:To operate an insulating film as a channel stopper by forming a groove in the surface of a semiconductor substrate by dry etching, and forming an Al2O3 film, SiO2 film, and Al2O3 film or SiO2-Al2O3 mixture film on the inside wall of the groove. CONSTITUTION:A groove is formed in the surface of an Si substrate 1 by dry etching, and an SiO2 film 3 is formed on the inner wall of the groove by a thermal oxidation, and an Al2O3 film 4 is so formed on the SiO2 film as to bury the groove by a CVD method. Thus, when a multilayer structure is formed, a load charge is secured to the boundary face between the SiO2 and the substrate, positive charge is induced at the boundary face between the SiO2 film and the substrate, a P<+> type is generated due to an increase in holes on the surface of the Si to act as a channel stopper, thereby preventing a leakage current between diffused layers 2. The insulating film formed in the groove provides similar effects even by the configuration of only the Al2O3 film, the SiO2 film + an SiO2.Al2O3 mixture film or an SiO2.Al2O3 mixture film, etc.

Abstract: PURPOSE: To obtain the title compound, useful as a photographic developer, an antioxidant for rubber and a polymerization inhibitor, stably, by the oxidation of p-isopropenylphenol, while decomposing the unreacted oxidizing agent with more than equimolar amount of SO 2  gas or its aqueous solution.  
     CONSTITUTION: p-Isopropenylphenol is oxidized with hydrogen peroxide or an orgainc peroxide in a water-insoluble high b.p. polar solvent in the presence of a strong acid to give hydroquinone. The unreacted peroxide is decomposed after the reaction by adding more than equimolar amount of SO 2  gas or its aqueous solution to the reaction mixture. The addition of SO 2  or its aqueous solution in more than the equimolar amount is useful not only for removing the residual hydrogen peroxide but also for the reduction of the undecomposed hydroperoxide of p-isopropenylphenol and for inhibiting the oxidation of hydroquinone in the reaction mixture. However a large excess amount is not preferable.
