摘要： PROBLEM TO BE SOLVED: To provide a method of classifying a ferrite magnet and its structure, wherein trouble caused by self magnetization of the ferrite magnet and its structure in a classification plant is substantially solved. SOLUTION: A method of classifying a ferrite magnet and its structure comprises a first process in which ferrite magnets and their structures are ground down, a second process in which the ground objects are cooled down to a temperature at which an inner magnetic field at a magnet operating point is reduced, and a third process in which an magnetic separating operation is carried out. The ground object is cooled down to a temperature at which the inner magnetic field at a magnet operating point is reduced, by which it is turned from a magnetic saturation state to an unsaturated state and demagnetized when it stops being cooled down. Therefore, trouble caused by magnetic attraction by self magnetization is substantially solved. This classification method can be applied to such a case in which even a ferrite magnet resides in a magnetic circuit.

摘要： PURPOSE:To produce a copper chromium thin wire excellent in mechanical and electrical properties of supersaturated solid solution by cooling/solidifying a molten copper chromium alloy containing a specified amount of Cr by a method of rotation-spinning in liquid and executing age hardening after drawing. CONSTITUTION:A cooling medium liquid layer is formed by centrifugal force in a cylindrical drum rotating at high speed. A molten copper chromium alloy containing 1.2-5.0weight% Cr is jetted from a nozzle into the cooling medium liquid and is cooled and solidified. By this method, a copper chromium thin wire consisting of supersaturated solid solution is obtained. This thin wire, after subjecting to solution treatment as required, is drawn and subjected to age hardening treatment. By this method, the copper chromium thin wire, which is good in cross-sectional roundness and low in variance of a diameter in the longitudinal direction, having high tensile strength, high electric conductivity and high heat resistance, is obtained.

摘要： PURPOSE:To improve reliability by adhering magneto strictive layers formed of an Fe-based amorphous magnetic alloy contg. Cr on a driven member. CONSTITUTION:The magneto strictive layers 2 are formed of the Fe-based amorphous magnetic alloy contg. Cr and are adhered to the driven member 1. This magnetic alloy has a chemically stable surface and, therefore, the oxide film on the surface is hardly generated and the adhesive strength, i.e. peeling strength when the alloy is adhered to the driven member 1 increases. The reliability is thus improved.

摘要： PURPOSE:To produce the title sputtering target without any crack and having a low content of the contained oxygen by placing the powder of a sputtering target material on a substrate, and carrying out heat treatment under pressure to the extent that the interface between the substrate and the powder is fused. CONSTITUTION:The powder of the sputtering target material is placed on the substrate. The substrate is appropriately made of one kind among W, Ta, Mo, Ni, and stainless steel. A soft magnetic material such as 'Sendust(R)' and alperm, a high magneto-striction material such as alfer, and ceramics such as Si3N4, AlN, SiO2, SiC, etc., can be used for the powder. The substrate carrying the powder is placed in a vacuum vessel, hermetically sealed, and hot-pressed by a hydrostatic pressure, or the powder is filled in a press die and hot-pressed. The heat treatment under pressure is carried out to the extent that the interface between the substrate and the powder is fused. By this method, a large-bore target made of a material exhibiting high brittleness can be obtained without generating cracking, and an economical sputtering target capable of being thermally, electrically, and excellently bonded to an electrode part can be obtained.

CONSTITUTION:A frame 2a in the state wherein thin burrs are made to float by electrolysis is put into water 8 in a tank 7. The temperature of the water 8 is adjusted by a temperature controller 12. When the temperature of the water 8 reaches and adequate value, an output is generated from an oscillator 10, and an ultrasonic vibrator 9 is driven. Thereby, the water 8 is vibrated, and part being dense and part turning to vacuoles temporarily generate. These vacuoles are destructed by the ultrasonic wave. By such a shock, the thin burrs on the frame 2a can be eliminated.

摘要： PURPOSE:To obtain an amorphous magnetic material which is improved in magnetic permeability particularly in a high-frequency region by subjecting a thin sheet-like Co amorphous alloy having a specific component compsn. to a heat treatment at the temp. below the Curie temp. of said alloy and below the crystallization temp. thereof while impressing a magnetic field thereto in the direction perpendicular to the thin sheet surface. CONSTITUTION:The Co amorphous alloy having the compsn. expressed by the formula I is subjected to the heat treatment in the perpendicular magnetic field under the above-mentioned temp. conditions, by which the magnetic anisotropy is induced into the amorphous magnetic material. The magnitude and direction of the induced magnetic anisotropy in the magnetic field can be variously changed by changing the treatment conditions. On the other hand, the magnetic permeability and loss coefft. are the constitutionally sensitive physical quantities to sensitively reflect the change of the magnetic anisotropy. The amorphous magnetic material which permits the improvement in the magnetic permeability and the control of the loss coefft. is, therefore, obtd. by subjecting the material to the adequate heat treatment as with this invention.

Sections except sections 5 brought into contact with the frames 11 in semiconductors 10 are insulated and coated 6 in cathode bars 4, and two cathode bars 4 are mounted in parallel. A soluble anode 7 is disposed faced oppositely to the magazine 3 on the bottom of the tank 2, and connected to an external power supply. Vertical shielding plates 8, 9 consisting of an insulator having the same size as a frame housing section are fitted to the upper and lower sections of the magazine, and the upper shielding plate 8 takes half size up to the surface of the plating solution from the upper end of the magazine. According to the constitution, plating treatment can be executed at magazine unit, and the frames can be taken in and out freely from the magazine, thus resulting in miniaturization, then equalizing plating-film thickness by a shielding wall.
