  • Patent number: 12209429
    Abstract: A fulldome display framework with a movable assembly adapted to dispose a plurality of display screens or projection screens to constitute a fulldome display includes a fixed frame engaged with a base surface and a movable frame disposed on the base surface and being movable relative to the fixed frame between an assembling position and a disassembling position along a predetermined route. The fulldome display is constituted when the movable frame is located at the assembling position to match with the fixed frame. In this way, after an LED fulldome display structure is installed on the present invention for example, the movable frame could be pulled out relative to the fixed frame along the predetermined route when a circuit board of a part of the fulldome display requires to be repaired, providing a certain working area for a repair worker to carry out repair and maintenance.

  • Patent number: 11841576
    Abstract: A spherical screen module unit includes a sector base including a sector carrier having an inner and outer arc edges; arc length of the outer arc edge is greater than that of the inner arc edge. An inner ramp frame is on the sector carrier and closer to the inner arc edge; an outer ramp frame is on the sector carrier and closer to the outer arc edge. When the spherical screen module unit is on a spherical screen assembling surface, minimum distance between the inner ramp frame upper surface and the spherical screen assembling surface is first height; maximum distance between the outer ramp frame upper surface and the spherical screen assembling surface is second height which is greater than the first height. A spherical screen structure including spherical screen module unit facilitates the module unit disassembly for repair, maintenance, or angle adjustment, and increases applicability in different environments.

  • Patent number: 10413933
    Abstract: A coating method has a reciprocating rotating step. A wire bar is rotated at a first rotational speed for coating a film on a web. In a process of rotating the wire bar at the first rotational speed, a tangential direction of the wire bar at a connecting area between the wire bar and the web is opposite to a moving direction of the web, and then the wire bar is rotated to restore to an original position at a second rotational speed. Meanwhile, the tangential direction is changed and is same to the moving direction of the web. The second rotational speed is far faster than the first rotational speed. A coating device has a base, the wire bar disposed across the base, and a rotation adjusting module connected to the wire bar for driving the wire bar to rotate reciprocatingly.

  • Publication number: 20100313772
    Abstract: A pressure-feedback-type squeegee module is provided, which includes a squeegee seat having a squeegee to contact a screen mesh of a screen, a pressurization part connecting to the squeegee seat to exert pressure on the squeegee seat, and at least two pressure induction modules configured at two sides of the squeegee seat to induce at least two pressure values transmitted when the squeegee contacts and depresses the screen mesh and to output the pressure values to a pressure control module. Based upon the received pressure values, the pressure control module will compute a proper way to adjust the pressurization part, so as to control depression pressure and pressure direction that the pressurization part acts on the squeegee seat.
