    • This invention aims at obtaining a large swing angle by a comparatively small apparatus. In an unloader having a grab bucket (55), four sheaves in a trolley (53) for suspending the grab bucket (55) are provided movably on a 45 DEG inclined surface. The four sheaves are divided into two groups. Each group comprises lift sheaves and opening and closing sheaves. One group is positoned at a lower end portion of the inclined surface, and the other group at an upper end portion thereof. The wires extending from the two groups of sheaves and connected to a suspension point is inclined at 45 DEG with respect to the axes of the sheaves. The sheaves for opening and closing the grab bucket are inclined at 45 DEG with respect to the axes of the sheaves of the trolley. One group of sheaves in the trolley (53) are moved upward, while the other group of sheaves therein are moved downward. Consequently, the grab bucket (55) is swung through substantially 90 DEG .
    • 本发明旨在通过较小的装置获得大的摆动角度。 在具有抓斗(55)的卸载机中,用于悬挂抓斗(55)的手推车(53)中的四个滑轮可移动地设置在45°倾斜表面上。 四个滑轮分为两组。 每组包括提升滑轮和开合滑轮。 一组位于倾斜表面的下端部分,另一组位于其上端部分。 从两组滑轮延伸并连接到悬挂点的线相对于滑轮的轴线倾斜45°。 用于打开和关闭抓斗的滑轮相对于手推车滑轮的轴线倾斜45°。 手推车(53)中的一组滑轮向上移动,而另一组滑轮在其中向下移动。 因此,铲斗(55)大体上90度摆动。

    • An electron microscope and electron microscopy for observing the magnetization of samples with high resolution. The microscope comprises an electron beam projecting means including a scanning coil (3) and objectives lens (4) to irradiate a desired part of a sample (51) with an electron beam (2) emitted from an electron source (1); and a detector means including a quarter wave plate (8), polarizer (9), and photodetector (11) to detect circular-polarized light from the irradiated part of the sample. Since the intensity of the circular-polarized light generated from the sample irradiated with the electron beam varies depending upon the direction of magnetization of the irradiated part and detecting direction of the light, the distribution of magnetization can be measured when the scanned images are observed by using the intensity of the circular-polarized light as luminance signals while scanning the irradiated part on the surface of the sample (51).
    • 用电子显微镜和电子显微镜观察高分辨率样品的磁化强度。 显微镜包括电子束投射装置,其包括用从电子源(1)发射的电子束(2)照射样品(51)的期望部分的扫描线圈(3)和物镜(4)。 以及包括四分之一波片(8),偏振器(9)和光电检测器(11)的检测器装置,用于检测来自被照射部分的样品的圆偏振光。 由于由电子束照射的样品产生的圆偏振光的强度根据照射部分的磁化方向和光的检测方向而变化,所以可以通过观察扫描图像时测量磁化分布 使用圆偏振光的强度作为亮度信号,同时扫描样品(51)的表面上的照射部分。
