    摘要： A process for producing an optically active alcohol represented by formula (I): ##STR1## wherein R.sub.1 is an alkyl group having from 2 to 11 carbon atoms, an alkenyl group having from 3 to 11 carbon atoms, an alkadienyl group having from 6 to 11 carbon atoms, a cyclohexyl group, an cyclohexylmethyl group, or a cyclohexylethyl group, provided that the olefin in the alkenyl group or alkadienyl group is not conjugated to the olefin at the 2-position thereof; and * means an asymmetric carbon atom,is disclosed, comprising subjecting an olefinic alcohol represented by formula (II): ##STR2## wherein R.sub.1 is the same as defined above to asymmetric hydrogenation in the presence of, as a catalyst, a ruthenium-optically active phosphine complex.According to the process of the invention, the desired optically active alcohols which are useful not only as intermediates for the manufacture of perfumes and vitamin E but also as liquid crystal materials can be produced with high optical purities.

    摘要： An actuator for liquid ejection which is provided with a plug for closing the ejection spout disposed at the distal portion thereof. This actuator is capable of preventing a residual liquid which is left inside the actuator after an ejection operation from being contacted with an outer atmosphere, thereby preventing the denaturing or degradation of the liquid. Further, it is capable of preventing a ejection spout from being stopped up and of preventing a filmy cover or block to be made. This plug is mounted on an elastic rod-like member disposed in and along the liquid-discharging passage, and is adapted to be moved backward, thus opening the ejection spout as the elastic rod-like member is forced to bend by an actuating rod when the actuator is pushed downward.
