    • Test patterns are applied to an IC under test under a test pattern address by which the first fail is caused and under other test pattern addresses. A defect candidate area is moved to the position where a charged particle beam can scan the area and defect candidate wiring portions are specified. A potential data of the specified wiring is acquired for each of the test patterns and stored in a memory. This process is process performed by sequentially stepping back the stop test pattern addresses. Then, a potential data of the specified wiring in thee specified area is similarly acquired for non-defect IC. The respective potential data of the IC under test and the non-defect IC are compared to locate the mismatch test pattern address and wiring.
    • 在测试模式地址下,测试模式被应用到测试模式地址,由此引起第一个故障,并在其他测试模式地址下。 将缺陷候选区域移动到带电粒子束可以扫描该区域的位置,并且指定缺陷候选布线部分。 针对每个测试图案获取指定布线的潜在数据并存储在存储器中。 该过程是通过顺序地退回停止测试模式地址来执行的。 然后,对于非缺陷IC,类似地获取指定区域中的指定布线的电位数据。 将待测IC和非缺陷IC的各自的潜在数据进行比较,以确定不匹配测试模式地址和布线。

    • A color balance adjusting apparatus is used for a full color copier in which an original image is illuminated by a light source; the illuminated image is exposed onto a photoreceptor to form electrostatic latent images corresponding to first, second and third colors for creating a color image; and each of the formed electrostatic latent images is developed into a visualized toner image. The color balance adjusting apparatus includes an infrared sensor for detecting toner density of the toner image formed with a toner having any one color of the first, second and third colors. The apparatus further includes automatic adjustment means which determines a relation of light intensity to toner density detected for one color by varying light intensity of said light source, and which determines optimal light intensity for the other two colors as predetermined functions of obtained optimal light intensity. Using this apparatus, automatic adjustment of the color balance for each copy mode can be effected in a short time with lesser consumption of electricity and supplies.
    • 色彩平衡调节装置用于其中原始图像被光源照射的全色复印机; 将照明图像曝光到感光体上以形成对应于第一,第二和第三颜色的静电潜像,以产生彩色图像; 并且每个形成的静电潜像被显影成可视化的调色剂图像。 色平衡调节装置包括红外传感器,用于检测由具有第一,第二和第三颜色的任何一种颜色的调色剂形成的调色剂图像的调色剂浓度。 该装置还包括自动调节装置,其通过改变所述光源的光强度来确定针对一种颜色检测的光强度与调色剂浓度的关系,并且确定其它两种颜色的最佳光强度作为获得的最佳光强度的预定函数。 使用该装置,可以在较短的时间内对每种复印模式的颜色平衡进行自动调整,同时电力和耗材的消耗较少。
