摘要： PROBLEM TO BE SOLVED: To efficiently produce a low-magnetostriction material by measuring the magnetic flux density of a grain oriented silicon steel sheet and also the visibility of ECP to determine plastic strain and previously grasping, in the stage before finish annealing, whether the sheet is a material capable of giving low magnetostriction or not. SOLUTION: The magnetic flux densities and ECP visibilities of plural finish annealed grain oriented silicon steel sheets are measured respectively to determine plastic strains, and the prescribed grain oriented silicon steel sheet is selected on the basis of these values and subjected to flattening annealing. As the basis of selection of the finish annealed grain oriented silicon steel sheet, this steel sheet simultaneously satisfies the following inequalities: B8>=1.90T, where B8 is a value after annealing at 850 deg.C for 4hr; 0.7

摘要： PURPOSE:To measure an electromagnetic force acting between magnetic materials by a method wherein a gap is formed between the magnetic materials, a yoke is arranged, a magnetic field whose magnitude is changed, is applied to the materials, a laser luminous flux is applied to a steel plate and its scattered luminous flux is used for an interference by the phase difference between its incident light and reflected light. CONSTITUTION:A gap is formed between a steel plate sample to be measured and a yoke. The gap is made definite without being changed according to the sample. It is excited by a prescribed magnetic flux density, and it is excited while an AC current is made to flow in order to compute an acceleration. Since the sample is attracted by the yoke and vibrated at this time, the vibration amplitude of the sample is measured by a laser Doppler vibration meter, and the acceleration is computed by it. The acceleration is found by differentiating the vibration amplitude two times, and an electromagnetic force is found from it by means of the following expression: F=ma [where F represents the electromagnetic force, (m) represents the mass of the part of the steel plate sample to which the electromagnetic force is applied, and (a) represents the acceleration of the steel plate].

摘要： PURPOSE:To provide an electromagnetic shield box that is effective from low to high frequencies by using a ferromagnetic material having one side furnished with a high-conductivity substance facing in the direction of incidence of electromagnetic waves. CONSTITUTION:An electromagnetic shield box uses ferromagnetic material such as magnetic steel or other existing material, and conductive material such as copper, aluminum and tin. An object to be shielded is completely enclosed by a ferromagnetic material provided with conductor of high conductivity. If copper is used for shielding from electric field components in electromagnetic waves, it is more effective to reflect electromagnetic waves by attaching copper to the front surface of incidence of a magnetic steel plate than to the rear surface. If a magnetic steel plate is used on the surface of incidence, the shielding effects are improved. For frequencies above 20kHz, the shielding effects are improved by facing the copper toward the direction of incidence of electromagnetic waves.

摘要： PROBLEM TO BE SOLVED: To provide an indirect energizing type continuous electrolytic etching method and an indirect energizing type continuous electrolytic etching apparatus for a metallic strip which realize stable electrolytic etching including fluctuation in the progressing velocity of a metallic strip.
SOLUTION: In the indirect energizing type continuous electrolytic etching method, a plurality of electrodes are successively arranged in the order of A system, B system, A system, B system... so as to be opposite to the etching face in which the etching pattern is formed in the metallic strip.
