    Abstract: The invention provides a method for regenerating with high efficiency a deteriorated catalyst of reduced activity, said catalyst originating from a heteropolyacid catalyst containing heteropolyacid formed of molybdophosphoric acid and/or molybdovanadophosphoric acid, or a salt thereof, to a heteropolyacid catalyst which exhibits approximately equivalent activity level to that of the fresh catalyst. Said method comprises mixing a deteriorated catalyst and a nitrogen-containing heterocyclic compound under the conditions whereunder ammonium ions and nitrate anions are present at such ratio that the amount of total ammonium ions per mol of total nitrate anions does not exceed 1.7 mols, drying the mixture and calcining the same.

    Abstract: A process for vapor phase catalytic oxidation of methacrolein to produce methacrylic acid at high yield and with stability over a prolonged period is provided. The process is characterized, in the occasion of producing methacrylic acid by vapor phase catalytic oxidation of methacrolein using a fixed bed shell-and-tube reactor, in that (1) the catalyst layer in each reaction tube is divided into at least two layers in the axial direction of the tube to provide plural reaction zones, and (2) each of the reaction zones is filled with the catalyst in such a manner that the amount of the catalytically active component per unit volume of the reaction tube decreases from the gas inlet portion toward the gas outlet portion.

    Abstract: A mechanical quantity sensor element making use of stress-magneto effect of noncrystalline magnetic alloy. Compression strain is preliminarily given to a thin belt made of noncrystalline magnetic alloy by carrying out treatment of applying an external force onto a surface of the thin belt. Suitable methods for applying the external force include; surface grinding by means of abrasive cloth or paper, shot-peening in which spherical fine grains are impinged onto a surface of a thin belt, stroking work in which a surface of a thin belt is scrubbed by means of a scrubber piece made of synthetic resin, rubber or other material, and the like.

    Abstract: An armature coil for a rotary electric machinery includes a plurality of identical coil blocks each formed by a plurality of turns of and elongated conductor. Each of the coil blocks includes two groups of axial sections which are diametrically opposed to each other, and curved sections joining the two groups to each other at each axial end. The axial sections of one of the groups is disposed in an inner cylindrical layer while the axial sections of the other of the groups are disposed in an outer cylindrical layer which is coaxial with the inner cylindrical layer. The coil blocks are combined with each other by circumferentially shifting one coil block from another in such a maimer that the axial sections are arranged circumferentially along the inner and outer cylindrical layers, one next to another.
