Abstract: An apparatus polishes an object material such as a film on a substrate. This apparatus includes a polishing table for holding a polishing pad having a polishing surface, a motor configured to drive the polishing table, a holding mechanism configured to hold a substrate having an object material to be polished and to press the substrate against the polishing surface, a dresser configured to dress the polishing surface, and a monitoring unit configured to monitor a removal amount of the object material. The monitoring unit is operable to calculate the removal amount of the object material using a model equation containing a variable representing an integrated value of a torque current of the motor when polishing the object material and a variable representing a cumulative operating time of the dresser.

Abstract: Quinolone derivatives are known as synthetic antimicrobial agents having a condensed pyridonecarboxylic acid skeleton, and those having substituents on various replaceable positions of said skeleton are known. In particular, if diastereomers exist, there are 4 or more kinds of stereoisomers. A mixture of diastereomers is a mixture of isomers having different physical properties and is difficult to apply as a drug as such. The present invention provides an antimicrobial 1-(1,2-cis-2-fluorocyclopropyl)-substituted quinolone derivative represented by formula I shown below which, although involving diastereomers, consists of a single stereoisomer. ##STR1## wherein R.sup.1 represents a methyl group, a difluoromethyl group, etc.; R.sup.2 represents a saturated nitrogen-containing heterocyclic group; A represents C--X.sup.3 or a nitrogen atom; X.sup.1 and X.sup.2 each represents a halogen atom; and X.sup.3 and Z represent a hydrogen atom, etc.
