Abstract: A base material processing apparatus detects the amount of widthwise misregistration of a base material in each detection position (Po, and Pa to Pd) lying on a transport path, and then calculates a difference between a detection value in the reference position (Po) and a detection value in each of the remaining detection positions (Pa to Pd) as a meandering amount. Subsequently, the base material processing apparatus determines coefficients obtained when a variation with time in each meandering amount is applied to a predetermined model function, and thereafter calculates coefficients of the model function predicted as the meandering of the base material in each processing position (P1 to P4), based on the determined coefficients and a positional relationship between the reference position (Po), the remaining detection positions (Pa to Pd) and the processing positions (P1 to P4).

Abstract: A transport apparatus includes a correction mechanism, a detector, and a meandering attenuator. The detector detects a widthwise position of elongated strip-shaped printing paper. The correction mechanism corrects the widthwise position of the printing paper, based on a detection result from the detector. The meandering attenuator is disposed upstream or downstream of the correction mechanism as seen in a transport direction. The meandering attenuator includes a plurality of attenuation rollers rotating while being in contact with the printing paper. When the printing paper passes over the attenuation rollers, the meandering of the printing paper is attenuated by the friction between the attenuation rollers and the printing paper. Thus, meandering exceeding the correction capability of the correction mechanism and new meandering occurring in the correction mechanism are attenuated.

Abstract: In an image recording apparatus, edge sensors are disposed in front of and behind a recording position on a transport path of printing paper. The edge sensors detect a widthwise position of the printing paper in respective positions upstream and downstream of the recording position. A controller in the image recording apparatus calculates the widthwise position of the printing paper in the recording position, based on detection results from the edge sensors. Thus, the widthwise position of the printing paper in the recording position is identified without the placement of an edge sensor in the recording position on the transport path.

Abstract: Provided is a wafer appearance inspection apparatus that can segmentize an inspection target region, enable expedited execution of an operation to set a sensitivity threshold to each region, and enhance the inspection efficiency. Pattern matching between the image region of a part of a standard wafer, which is defined as a template region, and the entire image region of the standard wafer is performed to compute an image editing value. The computed image editing value is used to edit an inspection target image. A region for which a threshold is to be set can be automatically confirmed by roughly specifying the region from among edited image regions displayed on the display. The confirmed region and a similar pattern region are searched and displayed. When the similar region is selected, the initial sensitivity threshold is displayed, and a change is made on an as-needed basis. The region of the set sensitivity threshold is displayed by the display color corresponding to the determined threshold.

Abstract: In printing apparatus, an edge sensor detects a serpentine amount caused by transportation of a web. A predicted waveform data generating unit generates predicted waveform data on the serpentine amount to be produced in the following web in accordance with actually measured waveform data on the detected serpentine amount. A correcting unit corrects a printing position of an image in accordance with a shift amount, and applies a corrected printing position to a printing head. Here, the shift amount is determined with the shift amount determining unit in accordance with the predicted waveform data. Accordingly, the shift amount is determinable in accordance with the actually measured waveform data on the serpentine amount detected with the edge sensor more accurately than that through a method in which a shift amount is directly determined. This allows suppressed misregister.
