Abstract: PURPOSE:To obtain excellent magnetic properties with minimized quantity of working by previously applying tensile strain in the extruding direction by specific extrusion in a process for applying by various plastic workings compressive strain to a hollow billet made of the titled alloy in the axial direction. CONSTITUTION:A container part 6 of a die, consisting of a mandrel 2 and a die 3, has a cavity having a hollow sectional form and also an opening area (sectional area perpendicular to the extruding direction) larger than that of a bearing part 7. At first a billet 1.. is put into the container part 6, which is pressurized at 530-830 deg.C by a punch 4 with making the extruding direction parallel to the axial direction. Subsequently, a new billet 1 is put into the container part 6 and pressurized in the same manner as mentioned above and hereafter the extrusion is carried out by repeating the above procedure. Then this billet is subjected to compression forming in the axial direction in a state where a part of the outside and inside peripheries of the billet is held free. If necessary, further compression forming is applied to a part of the billet in its axial direction with restraining a part of the billet and/or the outside periphery of the billet and also with holding at least a part of the inside periphery free.

Abstract: PROBLEM TO BE SOLVED: To provide a production process for ferrous sulfate monohydrate from iron ore and sulfuric acid that is suitable as a catalyst for hydrogenolysis of heavy hydrocarbon for such as coal liquefaction and hydrogenolysis of heavy oil, or as a starting substance for catalysts. SOLUTION: This process comprises the first step to treat iron ore with 70 wt.% or higher sulfuric acid at a temperature of <=140 deg.C to convert Fe2 O3 in the ore to FeH(SO4 )3 .4H2 O; the second step to hydrolyze the product to Fe2 (SO4 )3 .H2 SO4 .8H2 O, then to reduce the product with metallic iron to FeSO4 ; and the third step to crystallize out the product by evaporation. High-quality ferrous sulfate monohydrate that is composed of a coagulation of primary fine particles can be obtained with smooth separation into the solid and the liquid phases in a large scale by using iron ore and sulfuric acid and optimizing the reaction path. Thus, the production cost is inexpensive because the installation cost, the fixed cost relating to the installation and the proportional cost can be largely reduced.

Abstract: PURPOSE:To prevent the setting and conveyance of a sheet of paper from any hindrance by installing a rotation detecting means which detects the presence of the paper as rotating in contact with the skew paper in both directions, the conveying direction of the paper and the paper inserting direction orthogonal with the former. CONSTITUTION:A rotation detecting means 1000 is obliquely set up in the conveying direction of paper P and the paper inserting direction orthogonal with the former. Accordingly, at time of inserting the paper P into a paper storage part and vice versa, its friction with the paper P becomes lessened, so that the conveyance and insertion of the paper P can be done without any hindrance. In addition, since a detecting part of the rotation detecting means 1000 supports a turning piece 1003 in contact with the paper P at a spot short of the paper inserting direction, rotation of this rotating piece 1003 at time of the conveyance and inserting of the paper P is smoothed and, what is more, damage or the like to the rotating piece 1003 is eliminated, thus stable operation is brought into full play.
