  • Publication number: 20220379357
    Abstract: A fabricating apparatus and method for a flexible display screen. The fabricating apparatus for the flexible display screen comprises a roller mechanism and a jig (21); the jig (21) has a bearing surface (211) for bearing a flexible display panel (1); the bearing surface (211) is a curved surface; the roller mechanism comprises a roller (31); and the axis (x) of the roller (31) is parallel to the plain line (y) of the bearing surface. The fabricating apparatus for the flexible display screen is used for attaching a support layer (2) to the flexible display panel (1), so that the flexible display panel (1) is better bonded to the support layer (2), thereby reducing the probability that the flexible display panel (1) is separated from the support layer (2) during normal use.

  • Patent number: 10174587
    Abstract: Apparatus and methods are described for autonomously controlling fluid flow in a tubular in a wellbore. A fluid is flowed through an inlet passageway into a biasing mechanism. A fluid flow distribution is established across the biasing mechanism. The fluid flow distribution is altered in response to a change in the fluid characteristic over time. In response, fluid flow through a downstream sticky switch assembly is altered, thereby altering fluid flow patterns in a downstream vortex assembly. The method selects based on a fluid characteristic, such as viscosity, density, velocity, flow rate, etc. The biasing mechanism includes a semi-doughnut-shaped wall contour element formed along one side.
