    摘要: A drawing instrument for drawing an ellipse having two arms extending to left and right associated with operating mechanisms, so that when the arms are opened by a turning force of a first arm, a center moves along the straight line C, C' at a right angle to a straight line B, B' while maintaining two angles .theta. and .theta.', which are formed between the straight lines B, B' extending between centers of the bed seats or supports and left and right arms about the center, equal to each other.

    摘要: A process for dyeing a nitrogen-containing fiber, which comprises dyeing the fiber in a dye bath containing a halogenated hydrocarbon solvent, and a dye complex of an anionic dye with an amine of the formula: represents ##EQU1## wherein R.sub.1 represents a saturated or unsaturated hydrocarbon residue having 8 to 22 carbon atoms, R.sub.2 represents a saturated or unsaturated divalent hydrocarbon residue having 2 to 6 carbon atoms, said hydrocarbon residue for R.sub.1 and R.sub.2 may be of a straight or branched chain, n represents an integer of 1 to 4, each member of R.sub.2 may be the same or different when n is 2 or more, R.sub.3 and R.sub.4 each respresents a hydrogen atom, a lower alkyl or hydroxyalkyl group having 1 to 3 carbon atoms, and R.sub.3 and R.sub.4 may be the same or different.
