Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To provide both a method for decomposing an organosulfur compound by separating a microorganism growable within a wide temperature range including a high-temperature region and capable of specifically cleaving C-S bonds from the natural world by using the microorganism and a method for desulfurizing petroleum, or the like, containing the organosulfur compound. SOLUTION: An organosulfur compound is decomposed by making a microbial cell belonging to the genus Bacillus and having the ability to decompose the organosulfur compound or its cultured product act on the organosulfur compound. The microbial cell belonging to the genus Bacillus and having the ability to decompose the organosulfur compound or its cultured product is made to act on a petroleum or a petroleum product containing the organosulfur compound to decompose the organosulfur compound in the petroleum or petroleum compound. Thereby, a heterocyclic organosulfur compound can be decomposed specifically for C-S bonds under conditions of a wider temperature range than that of conventional methods (including a high-temperature region).  Furthermore, the C-S bonds in the heterocyclic organosulfur compound, e.g. dibenzothiophene or an alkyldibenzothiophene contained in a fossil fuel can specifically be decomposed under far milder conditions than conventional hydrodesulfurizing conditions and conditions of a much wider temperature range than that of usual microbial desulfurization (including a high-temperature region) and the effective desulfurization can resultantly be conducted.

IPC: G03G9/107
Filed: 1987-12-21
Abstract: PURPOSE:To reduce a fluctuation of quantity of electric charge of a ferrite carrier for electrophotographic developing agent and to make the developer durable for the use for a long time by specifying a compsn. of the ferrite. CONSTITUTION:A ferrite consisting of a compsn. expressed by formula I, satisfying also formula II, III, and IV is used in a ferrite carrier. In the formulas, when X exceeds a value defined by the formula, or a value of Z is out of a range defined by the formula, the value of resistivity exceeds a desired value. When the value of Y is below a value defined by the formula, calcination becomes difficult due to severe melt-sticking, and when the value of Y exceeds a value defined by the formula, saturation magnetization becomes smaller than a desired value. The ferrite of this invention is produced by crushing a mixture of each specified amt. of CuO, MnO, ZnO and Fe2O3 to a slurry, granulating thereafter by adding a binder thereto, then calcining and classifying.

Filed: 1987-12-17
Abstract: PURPOSE:To enable thickness of a bridge section in a Josephson junction device to be thinned with ease and good control by means of a system which provides high mass production and has a simple structure, by a method wherein an oxide superconducting film which is masked except a bridge section is exposed to hydrogen plasma, and thereby the surface layer of the exposed bridge section of the oxide superconducting film is chemically reduced. CONSTITUTION:An oxide superconducting film 2 is formed between electrodes in a pattern of a bridge type Josephson device having a bridge which is connected between the electrodes, and the resulting oxide superconducting film 2 is then covered with a mask 3, excepting a bridge section 2c. Subsequently, the oxide superconducting film 2 covered with the mask 3 is exposed to hydrogen plasma and thereby the exposed bridge section 2c of the oxide superconducting film 2 is for the surface layer 5 chemically reduced. Thus, a bridge type Josephson junction is produced. For example, after an Y-Ba-Cu-O-type oxide superconducting film 2 is formed on a substrate 1 of MgO, the superconducting film 2 is processed into a bridge type Josephson device pattern by means of an etching technique. Next, a photoresist 3 is coated allover on the substrate body and an opening section is then formed only in the position corresponding to a bridge section 2c. Therefore, when the masked oxide superconducting film 2 is exposed to hydrogen plasma 4, the surface layer 5 of the bridge section 2c is chemically reduced to be an insulating film.
