  • Patent number: 11680911
    Abstract: A marking region image is obtained by cutting out the part corresponding to a marking region from an article image obtained by imaging an article to be inspected. Then, whether or not the marking is properly provided is determined by performing a character recognition of a marking part for a marking region image. Further, an image of an article having no marking and no defect is stored as a reference image, whereas a marking periphery image obtained by removing the image of the marking part from the marking region image is compared to the reference image. By that comparison, whether or not any defect is included in the marking peripheral part of the marking region except the marking part is determined.

  • Patent number: 11621178
    Abstract: When pressure in a chamber is brought to atmospheric pressure and the chamber is filled with an inert gas atmosphere, the atmosphere in the chamber is sucked into an oxygen concentration analyzer through a sampling line such that oxygen concentration in the chamber is measured by the oxygen concentration analyzer. When the pressure in the chamber is reduced to less than atmospheric pressure, nitrogen gas is supplied to the oxygen concentration analyzer through an inert gas supply line simultaneously with suspending the measurement of oxygen concentration in the chamber. Even when the measurement of oxygen concentration in the chamber is suspended, reverse flow to the oxygen concentration analyzer from a gas exhaust pipe can be prevented, and the oxygen concentration analyzer can be prevented from being exposed to exhaust from the chamber. The configuration results in maintaining measurement accuracy of the oxygen concentration analyzer in a low oxygen concentration range.

  • Patent number: 11590764
    Abstract: An image is printed on the front surface M1 by discharging the inks to the front surface M from the discharge heads 321 (first head) facing the front surface M1 (recording surface) of the printing medium M from above. Thus, the inks discharged from the discharge heads 321 partially become mist to possibly produce ink mist. Accordingly, the ink cover 51 (first cover) is arranged between the discharge heads 321 and the front surface M1 of the printing medium M before the discharge heads 321 discharges the inks to the printing medium M. By providing the ink cover 51 for the front surface M1 of the printing medium M before printing in this way, the adhesion of the ink mist to this front surface M1 can be suppressed.

  • Patent number: 11590774
    Abstract: The wind velocity of the air injected by the air-blow dryers 7a, 7b is lower than that of the air injected by the air-blow dryers 7c, 7d. That is, since a large amount of moisture remains on the front surface M1 of the printing medium M passing through the air-blow dryers 7a, 7b, the printing medium M is dried while the flow of the aqueous inks is suppressed by injecting the air at a lower wind velocity. On the other hand, the moisture decreases on the front surface M1 of the printing medium M dried by the air-blow dryers 7a, 7b and the fluidity of the aqueous inks is reduced. Accordingly, the drying of the printing medium M is promoted by injecting the air at a high wind velocity to the printing medium M passing through the air-blow dryers 7c, 7d.
