    摘要： A 3-[(E)-1-propenyl]cephem compound represented by formula (I): ##STR1## wherein R represents hydrogen, a protective group for an amino group, or the group shown by formula (II): ##STR2## in which R.sup.3 is a protective group for an amino group, R.sup.4 is a protective group for a hydroxyl group, and W is --CH.dbd. or --N.dbd.; R.sup.2 represents a protective group for a carboxyl group; and X represents hydrogen or chlorine. The compound is useful as an intermediate for producing cephem antibiotics and is prepared by isomerizing the corresponding 3-[(Z)-1-propenyl]cephem compound in an inert organic solvent in the presence of an aromatic thiol. The compound of formula (I) wherein X is chlorine can be converted into a 3-[(E)-3-ammonio-1-propenyl]cephem derivative through the reaction with a tertiary amine.

    摘要： A piston ring reduces reciprocating friction between a piston and an inner wall surface of a cylinder, while maintaining reduction effect of the reciprocating friction. The piston ring is mounted in a ring groove of the piston, and slides against the inner wall surface of a cylinder liner or a cylinder. The piston ring includes: plural fine recessed portions formed in a barrel width region on an outer peripheral sliding surface of the piston ring; and a non-recessed portion area where no recessed portions are formed in the barrel width region. The non-recessed portion area is configured to have an area percentage within a range from 20-85% in the barrel width region where an area percentage of the barrel width region before the recessed portions are formed is defined to be 100%. The non-recessed portion area exists through an entire cross section in an axial direction of the barrel width.
