摘要： PURPOSE:To realize automatic efficient caulking even of fragile material by operating a punch and a die so that a caulked protrusion is sheared to have U-shaped profile, while at the same time, bending a caulked protrusion stripe of punched material with a radius larger than the minimum bending radius of the material. CONSTITUTION:At a station for forming a caulked protrusion, a caulked protrusion stripe 16 is intentionally sheared at one end to produce a U-shaped cantilever part. When the caulked protrusion 16 is bent with a radius 17 larger than the minimum bending radius of material, the tip of the caulked protrusion stripe 16 is press inserted into a caulked protrusion hole in a previously punched board at a final punching station. Consequently, the punched boards are automatically caulked successively to produce an integrated core continuously. According to the constitution, the caulked protrusion is not subjected to unnecessary stress other than bending stress resulting in protection of a caulked piece against shear fracture.

摘要： PURPOSE: To decrease the number of laser scanners and to improve the efficiency, reliabiity, performance, etc., of a scanning system by subjecting the relation between the rotating angle of a rotary dividing mirror which divides a laser beam with time and the angle of oscillating mirrors for scanning to phase control, etc.
CONSTITUTION: The laser beam 18 is changed over time-dividedly to transmission and reflection by the rotary dividing mirror 3 of an optical path selecting part 2. The transmitted beam 19a is scanned by the oscillating mirror 7a and is scanned at a microspot 9a to the surface of a steel sheet 10 by a lens 8a. The reflected beam 19b is scanned at a spot 9b by the oscillating mirror 7b and a lens 8b. The rotating speed of the mirror 3 is controlled by a rotation control device 12 on the basis of the moving speed of the sheet 10. The rotating angle of the mirror 3 and the oscillating angle of the morrors 7a, 7b are controlled by phase control parts 13a, 13b so as to have the specific phase relation in accordance with the signal from a rotating angle detector 11.

摘要： PURPOSE:To obtain an electromagnetic steel sheet having a magnetic property and an insulating property under a stable condition, while raising an iron loss- improving effect, by forming a tension film on one surface of the electromagnetic steel sheet, irradiating laser beams to the other surface, and then coating the other surface with an insulating film at a proper temperature. CONSTITUTION:A tension film is formed on only one surface of an electromagnetic steel sheet in a proper manner. Laser beams are then irradiated to the other surface to form laser-irradiated marks. An insulating film is applied to the laser-irradiated surface in a temperature range not to eliminate the laser-irradiating effect, e.g. under the condition that the temperature of the sheet is held below 600 deg.C. According to this method, an iron loss-improving effect is obtained by the conjunct effect of the tension film and the laser irradiation, and the electromagnetic steel sheet, excellent in its insulating property, voltage-withstanding property, corrosion-resistace, adhesiveness and space factor ratio, is obtained.

摘要： PURPOSE:To prevent the pressing flaw of a steel strip after high-temp. annealing owing to falling of stuck powder by coating electrostatically the powder particles of a separating agent for annealing to the steel strip from the bottom surface thereof just prior to coiling on a coiler side from an idler roll. CONSTITUTION:The powder particles of a separating agent for annealing are electrostatically coated to the bottom surface of a grain oriented electrical steel strip S by a gun 4 of an electrostatic powder painter disposed below the steel strip between an idler roller 2 and a coiler 1 in the stage of coiling the strip S with the coiler 1. The gun 4 and the strip S are electrified reverse in positive and negative polarities. The strip S after the electrostatic coating treatment is coiled with the coiler 1 and is subjected to high-temp. annealing. For example, magnesia clinker is used as the separating agent for annealing. There is no exfoliation of the film owing to contact with the roll, etc. and the pressing flaw after the high-temp. annealing owing to falling of the stuck powder to the gun and the peripheral part thereof is prevented according to the above-mentioned method.
