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.

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.

A curved-surface displaying module is adapted to be disposed on a curved-surface support and includes a display panel and at least one restricting device. The curved-surface support has an engaging surface and a reverse surface which face opposite directions. The display panel has a displaying surface and a reverse surface which face opposite directions. The reverse surface of the display panel is adapted to be connected to the engaging surface. The restricting device is disposed on the reverse surface of the display panel. The restricting device includes a restricting member. The restricting member has a connecting portion and a restricting portion. An end of the connecting portion is pivotally connected to the reverse surface of the display panel, and another end of the connecting portion is connected to the restricting portion. The restricting portion of the restricting member is controllable to pivot to the reverse surface of the curved-surface support.

A dome screen projection system includes a dome screen unit and two sets of projectors. The dome screen unit includes a top side, two opposite lateral sides extending downward from two opposite ends of the top side, and a curved projection surface extending downwardly from the top side between the opposite lateral sides. Each of the two sets of projectors are disposed on the top side proximally to one of the lateral sides. The two sets of projectors are directed toward the curved projection surface.

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.

A slit-type scraper device includes: a body, a first scraper portion, a cover, a second scraper portion, an air pressure through hole and a side cover unit. The body includes a groove and a slit portion abutting against the groove. The first scraper portion is abutting against the slit portion. The cover includes a plate portion. The second scraper portion is abutting against the plate portion, wherein the position of the second scraper portion is corresponding to the first scraper portion. The air pressure through hole is disposed on the body, in communication with the groove, and adapted to connect an air pressure connection member to input air pressure. The side cover unit is adapted to form an ink storage space between the plate portion and the groove, and form an ink output slit between the slit portion and the plate portion.

A winding apparatus providing steady tension includes: a loading unit rotatably supporting a roll of a sheet, releasing the sheet, and outputting an angle signal and a torque signal; a winding unit adapted to collect the sheet into a roll form; a dancer roller and a tension sensing unit separately arranged between the loading unit and the winding unit and outputting a shift signal and a tension signal respectively; and a control module having a calculating unit and a command unit. The calculating unit electrically connects with the loading unit, the dancer roller and the tension sensing unit to receive the signals and generates a torque command signal. The command unit electrically connects with the calculating unit and the loading unit to receive the torque command signal and produces a control signal by the torque command signal or a velocity signal.
