    摘要: A combination grinding machine grinds a plurality of axially arranged portions of a workpiece by use of a grinding wheel supported rotatably on a first wheel head and a superfinishing wheel supported rotatably on a second wheel head. A numerical control unit controls feed units for the first and second wheel heads in order to move the first and second wheel heads independently of each other in the axial direction of the workpiece and in the direction perpendicular to the axial direction, such that each of the axially arranged portions is ground by the grinding wheel, and simultaneously with this, another ground portion is superfinished by the superfinishing wheel.

    摘要: A crown ether compound is shown below and useful as a separating agent for chemical compounds. ##STR1## (In the formula, A and B represent hydrogen atoms, straight chain or branched alkyl groups having 1-6 carbon atoms, allyl groups having 6-10 carbon atoms, or aralkyl groups having 7-9 carbon atoms. Although A and B may be different groups, it is preferable that they be the same.R.sub.1 represents a hydrogen atom, a straight chain or branched alkyl group having 1-20 carbon atoms, or preferably an alkyl group having 6-16 carbon atoms. R.sub.1 may be bonded to any carbon atom on the cyclical ester group and its number is 1-12, and preferably 1-3. n represents an integer from 3-10, and preferably 4-8, with 5 or 6 being even more preferable.In addition R.sub.2 and R.sub.3 represent straight chain or branched alkyl groups having 1-30, and preferably 6-20 carbon atoms, or aryl groups having 6-18 carbon atoms, or aralkyl groups having 7-30 carbon atoms. The location of R.sub.2 and R.sub.3 may be anywhere other than the A and B substitution positions on the condensed ring, and although one of each of R.sub.2 and R.sub.3 is satisfactory, a maximum of 5 groups may be substituted. In addition, R.sub.2 and R.sub.3 may also be different.)
