  • Patent number: 12043024
    Abstract: A shift amount detecting chart is formed on web paper, and the shift amount detecting chart is photographed by an image pickup unit. An image processor calculates shift amounts smaller than a maximum shift amount in absolute values as correction values based on a variation trace of density peak positions from image data corresponding to the shift amount detecting chart photographed by the image pickup unit. A controller corrects printing timing with these correction values. Consequently, even when temporal variations occur to the shift amounts within a predetermined length, since the correction values are calculated based on the shift amounts smaller than the maximum shift amount in absolute values, an excessive correction can be prevented, thereby to improve printing quality.

  • Patent number: 12036662
    Abstract: A substrate processing apparatus includes a substrate processor and a substrate transporter. The substrate processor includes an upper holding device and a lower holding device configured to be capable of holding a substrate. In the substrate processor, the lower holding device is provided below the upper holding device. Therefore, a height position at which a substrate can be held by the upper holding device is different from a height position at which the substrate can be held by the lower holding device. The substrate transporter has first and second hands that hold a substrate. The second hand is located farther downwardly than the first hand. A substrate is received from or transferred to the upper holding device by the first hand. A substrate is received from or transferred to the lower holding device by the second hand.

  • Patent number: 12036583
    Abstract: A cleaner comes into contact with a lower-surface center region of a substrate held by a first holder, so that the lower-surface center region is cleaned. The cleaner comes into contact with a lower-surface outer region of the substrate rotated by a second holder, so that the lower-surface outer region of the substrate is cleaned. During cleaning of the lower-surface center region, the second holder is rotated about a vertical axis while not holding the substrate. Alternatively, during cleaning of the lower-surface center region, the gas injector arranged between the cleaner and the second holder injects gas toward the substrate from a first height spaced apart from the substrate by a predetermined distance. Further, during drying of the lower-surface center region, the gas injector injects gas toward the substrate from a second height closer to the substrate than the first height.

  • Patent number: 12030303
    Abstract: Disclosed is a printing apparatus in which web paper is transported to a printing face contact roller in a swirling form while a direction thereof is turned by first to fourth turning rollers. Heating units are arranged so as to face a printing face of the web paper between the two first and second turning rollers, between the two third and fourth turning rollers, and between the fourth turning roller and the printing face contact roller individually. Such arrangement can achieve a compact drying mechanism. The heating units each directly heat inks on the printing face, and thus do not overheat the web paper. Moreover, the heating units are not directed upward. This avoids contact of the web paper to a front side face of each of the heating units when the web paper slackens.

  • Patent number: 12035576
    Abstract: Disclosed are a substrate treating apparatus and a substrate transporting method. A first treating block includes a developing-treatment layer and an interface layer arranged in an up-down direction. Accordingly, the interface layer is couplable with the indexer block. Moreover, a substrate transport mechanism of the indexer block transports a substrate from one of buffer units located at a predetermined height position in a substrate buffer to another of the buffer units located at a different height position in the substrate buffer. Accordingly, the interface layer is accessible to the buffer unit located at a height position corresponding to the interface layer. Thus, the interface layer can be made compact. Moreover, the interface layer is located in the upper part or the lower part of the developing-treatment layer, leading to reduction in footprint.

  • Patent number: 12020958
    Abstract: A preceding wafer is transported from a chamber of a heat treatment apparatus after processing on the preceding wafer is completed. A temperature within the chamber at a time when the preceding wafer is transported from the chamber is defined as a transportation temperature, and a difference between a measurement temperature within the chamber measured after the preceding wafer is transported from the chamber and the transportation temperature is calculated as a decreasing temperature. The calculated decreasing temperature and a predetermined threshold value are compared with each other. When the decreasing temperature is larger than the threshold value, dummy processing of preheating an in-chamber structure such as a susceptor by light irradiation from halogen lamps and flash lamps is executed. In contrast, when the decreasing temperature is equal to or smaller than the threshold value, the dummy processing is not executed but processing on a subsequent substrate is started.

  • Patent number: 12014940
    Abstract: Disclosed is a substrate treating system and a substrate transporting method. For instance, it is assumed that an indexer block, a first treating block, and a second treating block are arranged in this order. In this case, for transporting a substrate treated in the second treating block to an indexer block, the substrate is necessarily sent through the first treating block without any treatment in the first treating block. However, the first treating block and the second treating block are both connected to the indexer block. Therefore, transportation of the substrate is performable directly from the second treating block to the indexer block without through the first treating block. Therefore, reduction in throughput is suppressible.
