Title: Production of single crystal
Inventor: KURAMOCHI KAORU
IPC: C30B15/12
Filed: 1989-09-29
Abstract: PURPOSE:To increase or decrease the oxygen concn. in a single crystal by immersing a cylindrical partition into a melt apart a suitable spacing provided between the bottom end thereof and the inner bottom wall of a crucible and increasing or decreasing the above-mentioned spacing, thereby changing the amt. of the high-oxygen concn. melt in the bottom of the crucible to be supplied to a single crystal growing region. CONSTITUTION:While a seed crystal 7 immersed in the melt 5 is kept rotated, the seed crystal is risen and the growth of the single crystal 8 is started. The melt 5a near a graphite heater 3 is higher in temp. than the melt 5b according to the growth of the single crystal 8, since the degree of mixing of the outer melt 5a and the inner melt 5b is low when the spacing between a control ring 10 and the bottom of the crucible 2 is low at this time. The melting amt. of the quartz crucible 2a and the ring 10, therefore, increases and the melt having the high oxygen concn. is formed. The melt 5a of the high temp. and high oxygen concn. flows into the melt 5b as the single crystal 8 is pulled up from the melt 5b. The melt of the high oxygen concn. in the bottom of the crucible 2 is, therefore, supplied to the single crystal 8 growing region without evaporating oxygen from the surface of the melt and the oxygen in the single crystal 8 is increased up to the required concn.

Title: Low iron loss grain-oriented silicon steel sheet good in adhesion of tension-applied type coating
Inventor: YAMAGUCHI HIROSHI
IPC: C21D9/46
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To increase the adhesion of coating, to impart strong tension to a steel sheet and to improve the effect of improving iron loss by applying metallic plating to the magnetically smoothened surface of a steel sheet, furthermore subjecting the plated face to electrolytic etching and thereafter forming tension- applied type coating. SOLUTION: As for the metallic plating, one or two kinds among the simple substances and alloys Ni, Co, Fe, Cu and Cr are used, an a plating layer having 0.1 to 5 μm thickness is formed. After that, it is subjected to electrolytic etching, and 1/10 to 2/3 of the plating layer thickness is eluted to make the plated face porous, and coating of phosphate-colloidal silica-chromic acid or the like is applied thereto. Furthermore, it is simple and rational that the electrolytic etching is executed in such a manner that, in succession to the metallic plating in an electrolytic plating bath, the polarity is reversed. Since the plated metal subjected to the etching is reduced into the plating bath as it is, it can again be reutilized for the plating of a steel sheet.
