    • A lens array element has a rectangular plate-like external shape, and includes plate surfaces that functions as light transmission surfaces; and a plurality of cellular lenses that are formed on at least one of the plate surfaces. Each of end faces 4 of the rectangular plate-like external shape forms an inclined surface that slants inward from a plate surface 6 on one side toward a plate surface 2 on the other side, and a reference surface 5 perpendicular to the plate surface is formed on a part of at least two adjoining end faces among the end faces. A front view shape of the reference surface region arranged side-by-side with the inclined surface of the end face is a trapezoid, an oblique side 7 of the trapezoid is disposed so as to extend from a plate surface on one side toward the plate surface 2 on the other side, and an upper side 9 of the trapezoid is disposed on a side of the other of the plate surfaces. Regarding the reference surface provided to the rectangular plate-like end face for optical alignment, the occurrence of inaccuracy due to the releasing properties at the time of molding the lends array element using a metal mold is suppressed.
    • 透镜阵列元件具有矩形板状外部形状,并且包括用作光透射表面的板表面; 以及形成在至少一个所述板表面上的多个蜂窝状透镜。 矩形板状外形的端面4形成从另一侧的板面2的一侧的板面6向内倾斜的倾斜面,形成与板面垂直的基准面5 在端面中的至少两个邻接端面的一部分上。 与端面的倾斜面并排配置的基准面区域的前视图形状为梯形,梯形斜面7配置成从板面向一侧朝向板 另一侧的表面2,梯形的上侧9设置在另一个板表面的一侧。 关于提供给用于光学取向的矩形板状端面的参考表面,抑制了使用金属模具成型使用阵列元件时的脱模性的不准确性的发生。

    • A variable F (a, n) defined by Equation (1) (wherein k (a, n) is a constant set on a step P (a, n) which is the nth step of a product a, Tave (a, n) is an average wait time for the same step as the step P (a, n) which is obtained from the past processing results, Tw1 (a, n) is a processing wait time which is a time difference between a processing end time for a step P (a, n--1) and a processing start time for the step P (a, n), N (a) is a final step for the product a, Te (a, N(a)) is a end time for a final step P (a, N(a)), Tout (a) is a target delivery date for The product a, and E (a) is the number of steps in which the product a is not yet processed) is set on all manufacturing steps of a product which is put in a manufacturing line. The processing start and end times for each step are determined in such a manner that the absolute value of the variable F (a, n) is smaller than a preset constant Fmax which is equal to or greater than 0 so that an initial manufacturing project is formed. The initial manufacturing project is corrected so as not to violate preset constraint conditions. Equation (1) equals: ##EQU1##
    • 由式(1)定义的变量F(a,n)(其中k(a,n)是在乘积a的第n步的步骤P(a,n)上设定的常数,Tave(a,n) )是与从过去的处理结果获得的步骤P(a,n)相同的步骤的平均等待时间,Tw1(a,n)是作为处理等待时间的处理等待时间,该处理等待时间是 步骤P(a,n-1)和步骤P(a,n)的处理开始时间N(a)是乘积a的最终步骤,Te(a,N(a))为终点 最后一步P(a,N(a))的时间,Tout(a)是产品a的目标交货日期,E(a)是产品a尚未处理的步骤数) 设置在生产线上的产品的所有制造步骤。 确定每个步骤的处理开始和结束时间,使得变量F(a,n)的绝对值小于等于或大于0的预设常数Fmax,使得初始制造项目为 形成。 纠正初始制造项目,以免违反预设约束条件。 等式(1)等于:F(a,n)= K(a,n)x {Tave'(a,n) - Tw1(a,n)} - + TR {Tave'(a,n + 1) - Tw1(a,n + 1)}
