    • A fuel system for feedback controlling an air-to-fuel ratio to maintain an ideally combustible air-fuel mixture includes an evaporation control device, which stores fuel vapors from a fuel tank and purges the fuel vapors stored therein into an intake system, and a fuel vapor evaluation system, which calculates an average of the feedback control parameters, estimates an amount of the fuel vapors stored in the evaporation control means based on the average feedback control parameter, calculates an amount of the fuel vapors replenished into the intake system based on the estimated amount of fuel vapors, and calculates a difference between an amount of fuel necessary for an ideally combustible air-fuel mixture and the replenished amount of fuel vapors. Fuel in an amount equal to the difference is delivered into the intake system.
    • 用于反馈控制空燃比以维持理想可燃空气燃料混合物的燃料系统包括蒸发控制装置,其将来自燃料箱的燃料蒸气储存并将其中储存的燃料蒸气吹扫进入系统,以及 计算反馈控制参数的平均值的燃料蒸气评估系统基于平均反馈控制参数估计存储在蒸发控制装置中的燃料蒸汽的量,基于平均反馈控制参数计算补充到进气系统中的燃料蒸汽量 燃料蒸汽的估计量,并且计算理想的可燃空气燃料混合物所需的燃料量与补充的燃料蒸气量之间的差。 相当于差值的燃料被送入进气系统。

    • In the rear of a zoom part consisting of a variator and a compensator, preceded by a focusing lens group, is a relay lens consisting of a front lens group and a rear lens group separated by an air space in which an attachment lens is removably positioned. This attachment lens is of positive power and has a primary principal plane which is dimensioned upon attachment to lie on the object side of a secondary principal plane of the zoom part. In one embodiment, the attachment lens is constructed in the form of a Galilean telescopic system which may include a meniscus lens convex toward the front.
    • 在由变倍器和补偿器组成的变焦部分的后部,在聚焦透镜组之前,是由前透镜组和后透镜组组成的中继透镜,该透镜组和后透镜组由空气间隔开,其中附接透镜可拆卸地定位 。 该附着透镜具有正的功率,并且具有初级主平面,该主平面在附着时被设计成位于变焦部分的次要主平面的物体侧上。 在一个实施例中,附件透镜被构造为伽利略伸缩系统的形式,其可以包括朝向前方凸起的弯月透镜。
