  • Publication number: 20140142096
    Abstract: A quinolone synthetic antibacterial agent having excellent properties as a medicine is provided, which has strong antibacterial activity not only to Gram-negative bacteria but also to Gram-positive cocci that have low sensitivity to quinolone antibacterial agents, and which exhibits high safety and excellent pharmacokinetics. A compound represented by the formula (I) or a salt thereof, or a hydrate thereof. Specifically, a quinolone derivative of the formula (I) wherein substituents R6 and R7 taken together with the carbon atoms to which they are bonded form a cyclic structure which may contain an oxygen atom as a ring constituent atom, the cyclic structure forming a 5-4, 5-5, or 5-6 fused bicyclic pyrrolidinyl substituent, the substituent being bonded to a quinolone mother skeleton Q containing a pyridobenzoxazine structure.

  • Publication number: 20140060491
    Abstract: A fuel injection control device includes a throttle opening read timing setter that sets the timing at which a throttle opening is read. The setter is triggered to detect the throttle opening used for calculation of a basic injection amount by the start of calculation timing of the basic injection amount (FICAL) if the FICAL is at the position corresponding to a toothless part of a crank pulsar rotor. The setter detects the throttle opening based on crank pulse interrupt according to a crank pulse if the FICAL is at a position other than the position corresponding to the toothless part.

  • Publication number: 20120323467
    Abstract: A fuel injection amount calculation method calculates a fuel injection amount to an internal combustion engine of a vehicle. The method can include calculating a relative intake pressure which is a difference between an intake pressure peak of intake air upon intake starting of a cylinder of the internal combustion engine and an intake pressure bottom of the intake air upon intake ending. The method can also include calculating the fuel injection amount based on the relative intake pressure.

  • Publication number: 20120100035
    Abstract: A magnesium alloy sheet having high impact resistance at low temperature, a magnesium alloy structural member using this sheet, and a method for producing a magnesium alloy sheet are provided. The magnesium alloy sheet is composed of a magnesium alloy containing Al and Mn. When a region from a surface of the alloy sheet to 30% of the thickness of the alloy sheet in a thickness direction of the magnesium alloy sheet is defined as a surface region and when a 50 ?m2 sub-region is arbitrarily selected from this surface region, the number of grains that are crystallized phases containing both Al and Mn is 15 or less. The maximum diameter of each of the crystallized phases is 0.1 to 1 ?m and the mass ratio Al/Mn of Al to Mn is 2 to 5. This magnesium alloy sheet has high impact resistance since it contains crystallized phases that are small in size and in amount contained and cause breaking and the like, and exhibits good mechanical properties even in a low-temperature environment.
