Title: Manufacture of amorphous magnetic core
Inventor: YOSHIZAWA KATSUTO
IPC: H01F41/02
Filed: 1986-06-05
Abstract: PURPOSE:To increase an occupation rate and to prevent the generation of exforiation of the smorphous thin film strip of a cut part when it is cut by a method wherein resin is impregnated into a tape-wound magnetic core before, in the middle of, or after performance of a heat treatment, and the side face of the magnetic core is polished. CONSTITUTION:Resin is impregnated into a tape-wound magnetic core before, in the middle of, or after performance of a heat treatment, and then the side face of the magnetic core is polished. The heat treatment is usually performed in the inert gas such as Ar ga, N2 gas and the like, or in a vacuum, or the heat treatment may be performed in the atmospheric air according to circumferences. It is desirable that the plate or the block and the like such as metal ceramic and the like is applied to the surface at right angle to the surface to be polished when a polishing work is performed, because an amorphous thin strip is hardly exforiated even when a work is performed thereon at high speed. Also, when a cut core is manufactured, the generation of exforiation of the amorphous thin strip of the cut part is prevented by cutting it almost vertical to the polished surface after polishing, the cut surface can be smoothed by polishing the cut surface after polishing, and the magnetic characteristics can also be improved.

Filed: 1978-10-23
Abstract: PURPOSE: To obtain the distinct images of which the negative and positive may be viewed in reversal when observed under radiation of white light by transferring the particle images formed on a photoreceptor to a mirror-surface-body-form (or black-body-form) substrate.  
     CONSTITUTION: The layer of the photoconductive material 2 of the electrophotographic photoreceptor 3 comprising providing the photoconductive material 2 on a conductive substrate 1 is charged and the particles (grain size; about 5W100μ, specific resistance; about 10 9 Ω.cm or over) 6 comprising making light-transmittable particles (glass particles, transparent plastic particles, etc.) conductive and suitably coloring the same are deposited on this with a particle sparyer 5. Next, images are exposed through a color negative film 7 to cause photo attenuation of the charges on the photoreceptor 3 corresponding to the exposed parts (the adhesion power of the A-colored particles of the portions radiated by A-color is reduced). Next, the light- transmittable colored particles of the reduced adhesion power are removed to form the particle images, after which these are transferred to an image acceptor (mirror- surface-body or black-body form substrate) 9. By radiaging white light to these transfered images, the distinct reversal images may be observed.
