摘要： A deflection apparatus arranged on the outer circumference of a funnel of a cathode ray tube includes a deflection yoke having vertical deflection coils and horizontal deflection coils. A compensation coil is provided on the outer circumference of a front end opening portion of the deflection yoke. An electrostatic capacitance element is connected between both end terminals of the compensation coil. The capacity of the electrostatic capacitance element is set such that an inducing voltage generated between both end terminals of the compensation coil is equal to or lower than a predetermined value.

摘要： Crude sodium hexafluorosilicate containing gypsum and various metal phosphates is refined into highly pure and sufficiently large crystals. First, the crude fluorosilicate is treated with a sodium chloride solution to dissolve gypsum. Then the solid phase is reconstituted into an aqueous slurry in which the concentration of Na is limited. This slurry is acidified and maintained at temperatures not lower than 80.degree. C. with continued stirring to cause recrystallization of sodium hexafluorosilicate.
