  • Publication number: 20200361735
    Abstract: In a method and a device for correcting meandering of a strip material in an apparatus that performs conveyance of the strip material at a non-contact state by floating a continuously traveling strip material by a floater group, the strip material is tilted by forcibly changing a height position in the widthwise direction of the strip material in at least one of a zone between the most upstream floater in the floater group and a conveyance roll located immediately upstream of such a floater, a zone between two adjacent floaters, and a zone between the most downstream floater in the floater group and a conveyance roll located immediately downstream of such a floater, whereby the height position in the widthwise direction of the strip material above the floater is changed and a static pressure applied to the strip material above the floater is changed to correct meandering thereof.

  • Publication number: 20200232082
    Abstract: The disclosure provides a fully new method for hot-dip metal coating treatment, as a method for treating surfaces of a metal strip by hot-dip metal coating, by which inherent issues in conventional immersion coatings and spray coatings are avoided. In the disclosed method for hot-dip metal coating treatment, a surface of a metal strip is coated by discharging a droplet of a molten metal toward the surface of the metal strip, using a nozzle system configured to discharge the droplet of the molten metal from a nozzle due to an action of the Lorentz force generated on the molten metal by sending an electric current to the molten metal in a chamber, the chamber being applied with magnetic flux in a given direction, while the electric current sent in a direction perpendicular to the given direction.

  • Patent number: 10551224
    Abstract: An encoder includes a light source. A booster circuit boosts a power supply voltage output by a battery, and outputs the boosted voltage. The voltage is applied to one end of a light-emitting diode. A driver circuit is inserted between another end of the light-emitting diode and a ground, the driver circuit controlling current flowing through the light-emitting diode. A voltage detector circuit detects a voltage between the light-emitting diode and the driver circuit. A control circuit causes the booster circuit to boost the power supply voltage when the voltage is lower than the power supply voltage; stops the boosting performed by the booster circuit when the voltage is equal to the power supply voltage; and controls the driver circuit such that, after the voltage reaches a predetermined value, current flows to the light-emitting diode.
