Abstract: PURPOSE:To reduce a difference in a resistance value and to obtain a high yield by a method wherein a conductor layer of 0.05 to 1mum is formed by a vapor phase method and a plated conductor layer of 0.5 to 10mum is formed on the conductor layer by an electrolytic plating method. CONSTITUTION:A photosensitive resin layer 3 used to form an electrode pattern is formed on an InSb thin film 2 on a glass substrate 1 by a photoresist treatment; in succession, Cu 4 is evaporated by a resistance-heating vacuum evaporation method. The photosensitive resin layer 3 is removed by using an organic solvent; after that, a photosensitive resin layer 6 is formed again by the photoresist treatment. Then, Cu is plated electrolytically; the photosensitive resin layer 6 is removed by using the organic solvent; after that, a lead electrode part 7 and a short-circuit electrode part 8 are formed; in addition, Cu, Ag or the like is applied by an electrolytic plating method; lastly, in order to protect the whole surface of an element including the short-circuit electrode part 8, the surface is coated with a polyimide 9. Thereby, a difference in a resistance value is reduced and a high yield can be obtained.

Abstract: PURPOSE:To simplify a process by a method wherein an In/Sb semiconductor thin film is thermally treated under a specified condition. CONSTITUTION:When an In/Sb semiconductor thin film formed on a substrate through an evaporation method or the like is moderately heat-treated in an atmosphere of air, inert gas, or mixed gas of them or in vacuum at a comparatively low temperature of 150-480 deg.C for 5-200 hours, the In/Sb semiconductor thin film does not change in hole mobility even after a magnetoresistive element formed of the film concerned has been used for a long period. Therefore, the element can be kept stable in the rate of a magnetoresistance change. By this setup, a manufacturing process can be simplified.

Abstract: PURPOSE:To improve the efficiency of manufacture of a magnetoresistance element, by a method wherein a thin film of a magnetoresistance body and a connecting part of a lead wire are coated with epoxy resin on a silicon resin coating and a glass plate is bonded on the thin film with epoxy resin. CONSTITUTION:A second ceramics substrate 22 is fixed on a first ceramics substrate 21 by a bonding agent 23, and a thin film 24 of a magnetoresistance body and an electrode terminal 26 of the magnetoresistance body are formed on the surface of the substrate 22. Connecting parts 28 and 29 of a lead wire 27 connecting the thin film 24, the electrode element 26 and the terminal 26 with an external wiring conductor terminal 25 of the substrate 21 are coated with silicon resin curing parts 30 and 31. Moreover, the curing parts 30 and 31 and the lead wire 27 are coated with epoxy resin curing parts 32 and 33. Then, a glass plate 34 is bonded on the curing part 32 by using epoxy resin as a bonding agent. The uppermost part of the thin film 24 which a magnetic moving body approaches is protected by the plate 34 in this way, and flatness and high sensitivity are obtained, while the breakdown of the magnetoresistance body and an electrode are prevented.

Abstract: PROBLEM TO BE SOLVED: To make a catalyst for decomposing a gaseous fluorine compound maintain high decomposition performance for a long time under reaction conditions by being composed of a perfluoro compound in which γ-alumina is added with at least one metal selected from V, Nb, and Ta and a chlorofluorocarbon compound. SOLUTION: A catalyst contains the largest number of strong acid points, uses γ-alumina which indicates high activity in the decomposition of a fluorine compound, and is composed of a perfluoro compound in which at least one metal selected from V, Nb, and Ta which uses a metal salt such as a chloride, a sulfate, an oxalic salt or an oxy salt, an alkoxide, an organometalic complex for the γ-alumina by an impregnation method and a chlorofluorocarbon compound. In this way, since high decomposition activity can be maintained for a long time by the γ-alumina catalyst for the decomposition reaction of a perfluoro compound the decomposition of which is more difficult than that of a chlorofluorocarbon, a catalytic decomposition method of a fixed bed passage system is made possible.

Abstract: PROBLEM TO BE SOLVED: To provide both a method for readily separating and recovering a heteropolyacid catalyst in a high recovery ratio used in producing a cycloalkyl carboxylate and a method for separating and recovering a heteropolyacid catalyst not causing reduction in the yield of the objective substance even when reusing the recovered heteropolyacid catalyst and repeatedly carrying out the reaction. SOLUTION: In a method for producing a cycloalkyl carboxylate by adding a carboxylic acid to a cycloolefin in the presence of a heteropolyacid catalyst, when the used heteropolyacid catalyst is separated and recovered, a solvent having 1.0-4.5 relative dielectric constant at 20-25 deg.C is added to the obtained reaction mixture solution after the reaction to separate the heteropolyacid catalyst. The carboxylic acid is added to the cycloolefin by repeatedly using the heteropolyacid catalyst recovered by the above method.

Abstract: PROBLEM TO BE SOLVED: To obtain cresol useful as a raw material for agrochemicals, etc. and various kinds of chemical products in a simple process by reacting toluene with dinitrogen oxide in the presence of a highly active catalyst. SOLUTION: Toluene is reacted with dinitrogen oxide in the presence of a zeolite catalyst containing a 3B group element (excluding aluminum) in vapor phase at 250-450 deg.C to provide the objective cresol. Lithium is preferably used as the 3B group element and ZSM-5 type zeolite, etc., is preferably used as the zeolite. The 3B group element is preferably included in the zeolite as a lattice component constituting a crystalline structure of zeolite by adding the 3B group element as a raw material when zeolite is subjected to hydrothermal synthesis. Use of the highly active catalyst suppresses complete combustion reaction and selectively produce cresol in high yield and reduce process number to one process and does not complicate separation of the catalyst or the product.
