    • An operating condition value is acquired at the time of internal combustion engine startup. If the acquired condition value is one of a plurality of reference condition values for which optimum values are defined, the optimum value for the reference condition value is set as a fuel injection amount. If, on the other hand, the acquired condition value is other than the reference condition values, an interpolated value, which is interpolation-calculated by using the relationship between the reference condition values and optimum values, is set as a fuel injection amount. The angular acceleration for fuel injection according to the interpolated value, which is a physical quantity related to the operating performance of an internal combustion engine, is then determined to correct the interpolated value in accordance with the difference between the actual angular acceleration and target angular acceleration.
    • 在内燃机启动时获取运行状态值。 如果所获取的条件值是定义了最佳值的多个参考条件值中的一个,则将参考条件值的最佳值设置为燃料喷射量。 另一方面,如果获取条件值不是基准条件值,则将通过使用基准条件值和最佳值之间的关系进行内插计算的内插值设置为燃料喷射量。 然后,根据作为与内燃机的运行性能相关的物理量的内插值来确定燃料喷射的角加速度,以根据实际角加速度和目标角加速度之间的差来校正内插值 。

    • It is an object to provide an L-ascorbic acid derivative which can keep the L-ascorbic acid stable to heat and light and thus has a long shelf life, which is high in permeability into the skin, which can be quickly hydrolyzed by phosphatase, an enzyme that is ubiquitous in vivo, and which exhibits physiological activities that are inherent to L-ascorbic acid and beneficial to health, a method for producing such an L-ascorbic acid derivative, and a skin-whitening cosmetic material. There is provided an ascorbic acid derivative comprising an L-ascorbic acid-2-phosphate ester or a salt thereof wherein the phosphate ester has a branched alkyl group, the L-ascorbic acid-2-phosphate ester being of formula [13]. The ascorbic acid derivative is produced by a method comprising reacting a branched alkanol with phosphorus oxychloride to synthesize monoalkyldichlorophosphate or dialkylmonochlorophosphate, reacting the thus obtained substance with 5,6-O-isopropylidene-L-ascorbic acid obtained by reacting L-ascorbic acid with acetone, and subjecting the thus obtained substance to acid hydrolysis. There is also provided a cosmetic material containing such an ascorbic acid derivative by 0.05 to 80 percent by weight. (wherein each of R1 and R2 is a hydrogen (H) atom or an alkyl group having branches and including 3 to 30 carbon atoms, but not both of R1 and R2 are hydrogen (H) atoms)
