  • Patent number: 11992973
    Abstract: The present invention provides a kneading method for a fiber-reinforced thermoplastic resin with which dispersibility of reinforcement fibers is enhanced and sufficient reinforcement fibers having a proper fiber length remain, and a fiber-reinforced thermoplastic resin plasticizing device and an extruding machine for carrying out the method. The kneading method comprises supplying a thermoplastic resin and reinforcement fibers into a cylinder of a plasticizing device, and rotating a screw to obtain a fiber-reinforced thermoplastic resin, wherein the size of a clearance between the bore of the cylinder and the screw is made different between an upstream side in the vicinity of a reinforcement fiber loading port and a downstream side, so that the clearance becomes larger from the vicinity of the reinforcement fiber loading port toward the downstream side compared with the upstream side.

  • Patent number: 11983856
    Abstract: An image display system includes a body, a first correction unit, and a second correction unit. The body houses a display unit to display an image and projects a virtual image, corresponding to the image, onto a target space using outgoing light of the display unit. The first correction unit corrects for distortion of the image. The second correction unit corrects a display location of the image on the display unit in accordance with an orientation signal representing a change in orientation of the body. Each of divisional areas of a display screen of the display unit is assigned with a distortion correction parameter for correcting for the distortion of the virtual image. The first correction unit applies distortion correction to each of the image regions of the image on the display screen based on a distortion correction parameter assigned to a divisional area where the image region is displayed.
