    • The present invention relates to a zoom lens which can shift images using a movable optical system so as to have components orthogonal to the optical axis, and can correct hand motion blur, and minimizes the deterioration of performance while attempting higher variable power. This zoom lens has, in order from an object, a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power, a third lens group G3 having positive refractive power, a fourth lens group G4 having negative refractive power, and a fifth lens group G5 having positive refractive power, and at least a part of the fourth lens group G4 can move so as to have components orthogonal to the optical axis, and a distance between each lens group is changed upon zooming from a wide-angle end state to a telephoto end state, and the following conditional expression is satisfied, 0.01

    • A fuel valve includes a cylindrical flow adjusting member having a cylindrical surface formed with two circumferentially extending V-shaped grooves for liquid fuel and air, respectively. The fuel valve further includes liquid fuel and air supply pipes having O-rings at their respective discharge ports which are kept in abutment with the cylindrical surface such that when the flow rate adjusting member is rotated to a position where the V-shaped grooves extend across and protrude from the respective O-rings, the discharge ports of the supply pipes communicate with the respective V-shaped grooves, so that liquid fuel and air flow. The depths, widths and positions of the respective V-shaped grooves are determined corresponding to an igniting position (preheating step), normal burning positions (high heat to low heat), and a discharge position such that the flow rates of liquid fuel and air can be adjusted in synchronization with each other.
    • 燃料阀包括圆柱形流动调节构件,其具有分别形成有用于液体燃料和空气的两个周向延伸的V形槽的圆柱形表面。 燃料阀还包括液体燃料和空气供应管,它们在它们各自的排放口处具有O形环,它们保持与圆柱形表面邻接,使得当流量调节构件旋转到V形槽延伸穿过的位置时 并且从各O形环突出,供给管的排出口与各V字槽连通,液体燃料和空气流动。 根据点火位置(预热步骤),正常燃烧位置(高热到低热)和排出位置来确定各个V形槽的深度,宽度和位置,使得液体燃料和空气的流量 可以相互同步调整。
