  • Publication number: 20210062357
    Abstract: An electrodeposition coating method includes a degreasing/cleaning step, a chemical conversion step, and an electrodeposition coating layer formation step. The degreasing/cleaning step includes a degreasing step of ultrasonically vibrating a degreasing solution in which a target object is immersed, using an ultrasonic vibrator. The electrodeposition coating layer formation step includes: a first electrodeposition step; a first rinsing step; a rinse water removal/reduction step of removing or reducing rinse water on a rinse water stagnating surface of the target object; a thermal flow step of allowing the first electrodeposition coating film to thermally flow so that the first electrodeposition coating film formed on a portion of the target object near a first counter electrode has a higher electrical resistance than the first electrodeposition coating film formed on a portion of the target object far from the first counter electrode; and a second electrodeposition step.

  • Publication number: 20200342185
    Abstract: An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other. The information reading unit generates a data string on the basis of a unit signal formed from a plurality of signals output from a group of detection units that detect the marks in synchronization and recognizes the digital code of the information bearing medium on the basis of a group of the data strings sequentially obtained from the array of the unit data zones.
