    摘要: A subjective vision testing system is used for visual function tests for examinees. The subjective vision testing system is provided with an optometric apparatus which selectively sets optical elements in front of both eyes of an examinee, an optotype presenting apparatus for displaying optotypes to the examinee, and a controller. The optotype presenting apparatus, based on a command signal for implementation of a binocular balance test, displays optotypes used for binocular balance tests. The optometric apparatus, based on a command signal for implementation of a binocular balance test, sets a first prism in front of the examinee's right eye and a second prism in front of the examinee's left eye. The second prism has a base direction vertically opposite to the first prism and the same prism power as the first prism.

    摘要: A finish annealed non-oriented electromagnetic steel sheet includes about 0.01 wt % or less of C, greater than about 1.0 wt % and at most about 3.5 wt % of Si, at least about 0.6 wt % and at most about 3.0 wt % of Al, at least about 0.1 wt % and at most about 2.0 wt % of Mn, at least about 2 ppm and at most about 80 ppm of one or more rare earth metals (REM), a maximum content of Ti and Zr being about 15 ppm and 80 ppm, respectively, wherein oxygen on the surface layer of the steel sheet is 1.0 g/m2 or less. Since the non-oriented electromagnetic steel sheet has desirable mechanical properties resulting from the increased amounts of Si and Al, a high magnetic flux density can be maintained without sacrificing a punching property as well as very low iron loss can be obtained even after stress relief annealing.

    摘要: A method of producing diphenyl sulfone compounds of the formula (I) ##STR1## wherein R is an alkyl having 1 to 8 carbon atoms, a cycloalkyl having 3 to 8 carbon atoms, an alkenyl having 2 to 8 carbon atoms or an arylalkyl which may have substituent(s) on the aromatic ring, comprising reacting 4,4'-dihydroxydiphenyl sulfone with a compound of the formulaR--Xwherein R is as defined above and X is halogen, characterized by conducting the reaction in 0.3-1.5 weight parts of an aqueous solvent per weight part of 4,4'-dihydroxydiphenyl sulfone in the presence of 1.5-3 moles of an alkali per mole of 4,4'-dihydroxydiphenyl sulfone. Since the method of the invention permits production of 4-substituted hydroxy-4'-hydroxydiphenyl sulfones, specifically 4-n-propoxy-4'-hydroxydiphenyl sulfone or 4-isopropoxy-4'-hydroxydiphenyl sulfone using an inexpensive solvent, with good selectivity and economical feasibility, they are industrially advantageous.
