    摘要： The present invention relates to quinolonecarboxylic acid derivatives having more excellent and broad antibacterial activities than the existing quinolone-series antibiotic. More specifically, it pertains to novel quinolonecarboxylic acid derivative represented by following formula 1, which have a derivative of 7-[8-(alkoxyimino)-2,6-diazaspiro[3.4]oct-6-yl] as a substituent, and pharmaceutically acceptable salts and isomers thereof: Wherein A is C—H, C—F, C—Cl, C—O—CH3 or N; Y is H or amino; R1 is cyclopropyl or 2,4-difluorsophenyl R2 is C1-4 alkyl; and R3 is H or C1-4 alkyl.

    摘要： In a hybrid DC electromagnetic contactor, by including a power unit for supplying a certain power voltage; a main contact point of a breaking switch for providing a supply path of the power voltage by being switched in accordance with a voltage apply to an operational coil; a switch for providing a supply path of the power voltage according to a gate signal; a snubber circuit for charging voltage at the both ends of the switch in turning off of the switch and being applied-discharged an electric current when the charged voltage is not less than a certain voltage; and a discharge current removing unit for removing the discharge current by providing a discharge current path to a load block in turning off of the switch, it is possible to minimize a size of leakage current when the main contact point and the semiconductor switch are turned off, and accordingly it can be practically used.
