Title: Stabilizing method of characteristic of amorphous magnetic material
Inventor: SAKAKIMA HIROSHI
IPC: H01F1/153
Filed: 1980-10-31
Abstract: PURPOSE:To obtain stable characteristics with small aging by coating an amorphous magnetic alloy with a magnetic distortion constant within a specific range with resin. CONSTITUTION:In case the magnetic distortion constant lambda is negative, an amorphous magnetic alloy shows large deterioration in characteristics after resin molding corresponding to the magnitude of¦lambda¦. Yet the material whose constant lambda is zero shows that deterioration of characteristic due to resin molding does not take place but thereafter a remarkable deterioration of magnetic permeability. On the contrary, in case lambda is larger than zero, the magnetic characteristic after molding will deteriorate in proportion to the magnetiude of lambda. However, with an amrophous magnetic alloy in the region of 0<lambda<10<-6>, the magnetic characteristic does not largely deteriorate by resin molding. Therefore, by using this method, unstability due to aging in the characteristic inherent to the amorphous magnetic material can be largely improved.

Filed: 1982-09-03
Abstract: PURPOSE:To make it possible to trace and control welded parts of metal strips in a continuously processing line in which the ends of a plurality of coil strips are successively welded together, by correcting tracking errors with the use of the correlation between the measured thickness values of the metal strips on the inlet side and outlet side of the line. CONSTITUTION:For example, in a continuous annealing line, detected thickness data on the introduction side at every predetermined transferred distance in each area, from a double cut shear and a welding machine to an inside loop car, up to the outlut thereof, in a continuous annealing furnace, to an outside loop car outlet and thereafer, are stored. The stored values of memory devices 21a through 21e in the areas are stepped up at every index due to the outputs of the associated speed meters 8, 14, 16, and the end addresses are shifted to the associated addresses in the next areas in accordance with the expansions and retractions of the loop cars. Further, by comparing the measured thickness value on the carrying-out side with the stored value on the introduction side, a tracking error is corrected if the correlation is broken. Thus, the information on welded parts or the like may be traced with a high degree of accuracy.

Abstract: PURPOSE:To increase the working efficiency for correction of unbalance, by converting the degree of unbalance measured previously into the area and depth, giving the grinding in accordance with the area and depth to detect successively the grinding degree and accordingly keeping the prescribed balance. CONSTITUTION:Both the position and degree of unbalance are previously detected for the unbalance of a rotor through a test of rotation, etc. Then the degree of unbalance is converted into the area and depth of correction at the unbalanced position to start the grinding. After this, the grinding degree is successively detected for the correction surface from a difference of level between a ground surface and a non-ground surface, and the grinding is carried out up to a degree corresponding to an obtained degree of unbalance. Thus the unbalance of a rotor is corrected. In the grinding work, the satisfactory control is given to the working depth to eliminate a prescribed degree of unbalance through the grinding and with high accuracy.
