    • The present invention provides a waterproof box which can improve water performance and work efficiency, and can reduce space. When washing water hits in the lower surface 33h of first waterproof portion 33 of an upper cover 15, spay is generated. At this time, an outer surface 30b, which is formed in a tapered shape, of first waterproof portion 30 abuts on an inner surface 33g, which is formed in a tapered shape, of the first waterproof portion 33. Further, the outer surface 30b engages with the inner surface 33g. As a result, the inlet of a minute path 27 is closed. Even if water leaks, force of the water is reduced because the water enters in a groove 33b or 35a. The water in which force of the water is reduced falls down.
    • 本发明提供一种能够提高水性能和工作效率的防水箱,能够减少空间。 当洗涤水在上盖15的第一防水部33的下表面33h中产生喷溅时,产生喷溅。 此时,第一防水部30形成为锥形的外表面30b与第一防水部33的锥形形状的内表面33g抵接。此外,外表面30b 与内表面33g接合。 结果,微小路径27的入口被关闭。 即使水泄漏,由于水进入凹槽33b或35a,水的力也减小。 水的力量减少的水落下。

    • The present invention provides a sputter profile simulation method which reduces a calculation time. The method comprises the steps of calculating sputter trajectories of particles emitted from a sputter target; projecting the sputter trajectories onto one or more first planes; extracting an outline of a contact hole on a second plane parallel to one of the first planes; defining two shadow points preventing the particles from going to a film-growth calculation coordinates point; and judging that, out of the sputter particle trajectories projected on the first plane, the sputter trajectories between two lines as film-growth contributing trajectories, the two lines joining the film-growth calculation coordinates point to each of the two shadow points.
    • 本发明提供了减少计算时间的溅射轮廓模拟方法。 该方法包括以下步骤:计算从溅射靶发射的粒子的溅射轨迹; 将溅射轨迹投影到一个或多个第一平面上; 在平行于所述第一平面之一的第二平面上提取接触孔的轮廓; 定义两个阴影点,防止颗粒进入胶片生长计算坐标点; 并且判断出在投影在第一平面上的溅射粒子轨迹中,作为膜生长贡献轨迹的两条线之间的溅射轨迹,连接膜生长计算坐标的两条线指向两个阴影点中的每一个。

    • An electrometer having small width size and stable characteristics includes a chopper portion for chopping electric line of force emitted from an object to be measured. The chopper portion is constituted with a tuning fork type bending vibrator including a first metal plate as a detection electrode portion for receiving electric line of force, a second metal plate and an insulating plate for connecting the first and second metal plates in a plane. The bending vibrator is arranged such that its vibrating direction is coincident with direction of electric line of force, so that the width size of the electrometer can be reduced and the characteristics thereof can be stabilized.
