    摘要： An air/fuel ratio correction cylinder determining section 25 specifies, based on the peak phase, a cylinder for which an air/fuel ratio is to be corrected. A cylinder-specific air/fuel ratio correcting section in the form of respective cylinder correcting sections 31 through 34 corrects an amount of fuel to be supplied to a cylinder which becomes an air/fuel ratio correction target. A cylinder for which an air/fuel ratio deviates from the remaining cylinders is specified as a fuel amount correction target based on a change in the output value of the air/fuel ratio sensor.

    摘要： Several new 10-formyl and 10-hydroxymethyl derivatives of 5,8,10-trideazapteroic acid are provided, as well as procedures for their preparation. These compounds were shown to be powerful inhibitors of glycinamide ribonucleotide formyltransferase (GARFT), an enzyme that mediates the de novo biosynthesis of purine nucleotides that are required for DNA synthesis and cell division. Due to their ability to interfere with nucleotide biosynthesis and to penetrate microbial cells they are potential anti-microbial agents and are useful for the treatment of opportunistic infections in AIDS and other infections caused by micro-organisms that are resistant to conventional anti-bacterial and anti-fungal agents.

    摘要： A luggage cart includes a supporting tray and a latching mechanism. The latching mechanism includes a top seat, a fastening member, an actuating member, a bottom seat fixed to the supporting tray, and a latch bolt. The fastening member has a flange cap portion adapted for securing to a luggage container, and a shaft portion formed with a first locking part. The latch bolt is mounted to the bottom seat and is slidingly engaged with the actuating member. The actuating member is movable to move the latch bolt from a locking position, where the latch bolt engages the first locking part of the fastening member, to an unlocked position, where the latch bolt is disengaged from the first locking part to permit removal of the fastening member.

    摘要： The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.

    摘要： A method and apparatus for providing an oscillating signal within a transmitter/receiver circuit is described. The transmitter/receiver circuit may include an oscillator that generates an oscillating signal that may be provided to a low power, low gain mixer of the transmitter/receiver circuit along a shorter circuit path that includes low power circuitry, such as low power buffers and low power frequency dividers. The oscillating signal may also be provided to a high power, high gain mixer along a longer circuit path that includes high power circuitry, such as high power buffers and high power frequency dividers. Specifically, the low power circuitry is adapted to consume less power in an ON state than the high power circuitry in an ON state, and the shorter circuit path has a shorter electrical path length than the longer circuit path.
