摘要： In an ultrasonic inspection performed on an inspection object including a fine and multi-layer structure such as a semiconductor wafer and a MEMS wafer, a defect is detected by: separating a defect present inside from a normal pattern; obtaining an image of the inspection object by imaging the inspection object having a pattern formed thereon to enable a highly sensitive detection; generating a reference image that does not include a defect from the obtained image of the inspection object; generating a multi-value mask for masking a non-defective pixel from the obtained image of the inspection object; calculating a defect accuracy by matching the brightness of the image of the inspection object and the reference image; and comparing the calculated defect accuracy with the generated multi-value mask.

摘要： The stacked cell manufacturing method includes the steps of executing zigzag-folding of a band-like separator by the intermediary of a zigzag-folding mechanism, alternately feeding a positive-plate and a negative-plate onto the separator as folded back every time the separator is folded back by the zigzag-folding. A positive-plate transfer head and a negative-plate transfer head are set so as to alternately undergo a linearly reciprocating transfer in a horizontal direction at least on the table, the direction of a horizontal and reciprocating transfer made by the positive-plate transfer head and the negative-plate transfer head is set to coincide with a folding-back direction of the zigzag-folding of the separator, and a force caused by the horizontal and reciprocating transfer alternately made by each of these transfer heads is imparted to the separator guided onto the table, thereby executing the zigzag-folding while the separator is drawn onto the table.

摘要： In case-based anomaly detection in equipment such as a plant, it is necessary to search entire learned data for partial data close to newly observed data. Which needs a long computation time. In order to solve this problem, there is provided a method, the learned data is clustered into clusters and the centers of the clusters as well as data pertaining to the clusters are stored in advance. Data close to newly observed data is selected from only the learned data pertaining to a cluster close to the newly observed data. Then, a normal model is created from the selected data and an anomaly measure is found whereas a threshold value is determined. Subsequently, an anomaly measure is found from the newly observed data and the created normal model. Then, this anomaly measure is compared with the threshold value in order to detect an anomaly of the equipment.
