  • Patent number: 11020786
    Abstract: A system and apparatus is disclosed for controlling a restraining force applied to a panel. The apparatus includes a die, a binder supporting the panel against the die, and a punch used to draw the panel into the die. A restraining element is disposed on one of the die and the binder that engages a surface of the panel and applies a restraining force onto the panel. A strain gauge is disposed inside at least one of the die and the binder that engages a surface of the panel to measure the restraining force applied to the panel. The level of restraining force applied by the restraining element onto the panel is controlled based upon the restraining force measured by the strain gauge.

  • Patent number: 10889935
    Abstract: A dyeing method in which a transparent resin body having a surface applied with a dye is heated to fix the dye to the transparent resin body comprises a heating step of irradiating a laser beam having a wavelength less likely to be absorbed by the dye toward the transparent resin body applied with the dye on the surface while relatively scanning the laser beam with respect to the transparent resin body to heat a to-be-dyed region of the transparent resin body to fix the dye, wherein the laser beam is irradiation to heat by changing a laser beam irradiating condition with respect to a portion of the transparent resin body to be heated so that a heating temperature on the transparent resin body by irradiation of the laser beam is substantially equal throughout an entire area of the to-be-dyed region.

  • Patent number: 8356500
    Abstract: In a method and a device for creating a symbol in a workpiece surface via stamping (scoring or plastic forming under compressive conditions); the resultant stamping depth is measured and/or regulated constantly by using a distance sensor which is mounted on the stamping needle and is movable therewith. The stamping needle is placed on the workpiece surface before stamping is begun, thereby resulting in a first distance between the distance sensor and the workpiece surface. A second distance between the distance sensor and the workpiece surface is obtained during the subsequent stamping procedure, and when the stamping needle is pressed into the workpiece surface. The stamping depth results from the difference of the two distances.
