Compounds of the formula ##STR1## wherein R.sub.1 is hydrogen or a (C.sub.1 -C.sub.4) alkyl group, X is a straight or branched chain C.sub.1 -C.sub.4 alkylene group and R.sub.2 is a carboxyl group or a sulfo group; and the pharmaceutically acceptable salts thereof exhibit strong inhibitory activities against a wide variety of Gram-positive and Gram-negative bacteria including Psendomonas aeruginosa, indolepositive Proteus and Enterobacter aerogenes, and also have an increased and prolonged serum level in a living body. The compounds are therefore useful as antibacterial agents for the treatment of infectious diseases caused by Gram-positive and Gram-negative bacteria.

An improvement is provided in and relating to a capacitance-type record medium wherein an information signal is recorded as a variation in the geometrical shape of its surface area, and is played back by the variation of the capacitance between its surface and an electrode of a reproducing stylus scanning the surface of the record medium relatively which occurs according to a variation in the geometrical shape of its surface area. The improvement consists in the fact that at least the surface area of the record medium is formed of (1) a material composed of an electrically conductive substance and a copolymer consisting of 98 to 65% by weight of vinyl chloride, 2 to 20% by weight of an alkyl vinyl ether with the alkyl group having 4 to 18 carbon atoms and/or a vinyl ester of a fatty acid in which the fatty acid residue has 4 to 18 carbon atoms and 0 to 15% by weight of another monomer copolymerizable with these compounds, or (2) a material composed of an electrically conductive substance and a polymer mixture consisting of at least two polymers in which the proportions of the constituent monomers are the same as in the aforesaid copolymer.
摘要:
A process for producing a cyclopentadiene resin by heat copolymerizing a cyclopentadiene monomer and a comonomer copolymerizable therewith, which comprises(a) using a vinyl monomer containing an ester linkage or a hydroxyl group as the comonomer, and(2) feeding the polymerizable ingredients and optionally an inert solvent from a material-preparing zone to a polymerization zone to polymerize the polymerizable ingredients, feeding the polymer solution formed in the polymerization zone into a separating zone to separate a low-boiling mixture consisting of the unreacted monomers, a by-product oil and optionally the inert solvent from the resulting cyclopentadiene resin, and recycling at least a part of the separated low-boiling mixture to the material-preparing zone for use as a polymerizable ingredient.
摘要:
A platelet aggregation inhibitor comprising a quinolone derivative or a pharmaceutically acceptable salt thereof as an active ingredient, and a novel quinolone derivative or a pharmaceutically acceptable salt thereof useful as a platelet aggregation inhibitor.
摘要:
Switching of topics in video content is detected using a telop included in the image, and the content is segmented by topics.First a scene-change point where the scene changes significantly is detected in the video content on the basis of the switching of images. Then, an average image of frames one second before and after the scene-change point is produced. The average image is used to detect, in a highly accurate manner, whether or not a telop is displayed. Then, a section in which the same stationary telop is displayed is detected. Index information related to the time period of each section in which the same stationary telop is displayed is produced.
