摘要:
A compound of the formula: ##STR1## wherein R is a lower alkyl group substituted with two or three fluorine atoms and X is a halogen atom, a lower alkyl group or a trifluoromethyl group, which is useful as a herbicide against a variety of weeds with a high selectivity to cotton, wheat and rice plants.
摘要:
A herbicidal composition which comprises as an active ingredient a m-phenoxybenzamide compound of the formula: ##STR1## wherein X, which may be the same or different, is a halogen atom or a lower alkyl or lower alkoxy group, n is zero or an integer of 1 to 5 and R is a group of the formula: ##STR2## (in which R.sub.1 is a hydrogen atom or a lower alkyl or lower alkenyl group and R.sub.2 is a lower alkyl, lower alkenyl, lower alkynyl, lower alkoxy, lower cycloalkyl, lower haloalkyl, lower alkoxy-substituted lower alkyl, lower cyanoalkyl, lower alkylamino-substituted lower alkyl or benzyl group) or an ethylenimino, pyrrolidino, dimethylpyrrolidino, piperidino, methylpiperidino, hexamethylenimino, morpholino or dimethylmorpholino group.
摘要:
In an electrostatic reproduction machine there is provided one or more rollers capable of rotating in union with a copy sheet being advanced, in the course of travel of the copy sheet. Sensing switches are provided for sensing nonuniformity in rotation of the rollers which may occur in abnormal copy sheet transportation states and, more particularly, in a jam state. The outputs from the sensing switches are utilized for identifying the abnormal machine states.
摘要:
A cephalosporin derivative of formula (I): ##STR1## wherein X is an --OCOCH.sub.3 group or an --S--Het group in which Het is a 5- or 6-membered heterocyclic ring containing one to four hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur atoms, which may be substituted with one or more substituents, and the non-toxic pharmaceutically acceptable salts thereof which are useful as an antimicrobial material and which are prepared by the reaction of a compound of formula (II): ##STR2## or a reactive derivative thereof, with a compound of formula (III): ##STR3## wherein X is as defined above, or a derivative thereof.
