Abstract:
A feeding device and a variable squeezing mouth are provided. The feeding device includes a first roller, a second roller and a middle guiding structure. The second roller and the first roller have a first zone therebetween. At least a part of the middle guiding structure is positioned in the first zone. The middle guiding structure has a passage being aligned with and connected to the first zone. The variable squeezing mouth includes a main body, a collet and a nut. The collet includes a base and at least two arms. The arms form a filament outlet. While the nut or the collet is moved with respect to the main body, the at least two arms and the nut are pressed against each other, so that a distance between the at least two arms is changed, and the size of the filament outlet is changed.

This disclosure relates to a biological tissue forming method includes the following steps: providing a biological tissue forming package with a base, a membrane, a sliding assembly and a sealing film that seals a chamber of the base used for receiving the membrane and the sliding assembly with one of the base and the sealing film being light-transmitting; passing a biological tissue fluid through the sealing film and the sliding assembly so as to be dispensed on the membrane; moving the sliding assembly away from a covering position used for covering the membrane via at least one passive magnetic element so as to expose the biological tissue fluid on the membrane; and emitting the biological tissue fluid exposed on the membrane by a curing light transmitting through the one of the base and the sealing film so as to cure the biological tissue fluid into a biological tissue.
Abstract:
A laminating device for composite material includes a laser device, a hot roller assembly which has a first hot roller and a second hot roller, a cool roller assembly which has a first cool roller and a second cool roller, an axial roller-driving unit and a spring force-adjusting unit. The laser device provides a laser beam onto laminating surfaces of two separate composite materials prior to the hot roller assembly. The axial roller-driving unit drives the first hot roller and the second hot roller, and the first cool roller and the second cool roller, to undergo relative movement in a first direction. The spring force-adjusting unit provides spring forcing to the first hot roller and the second hot roller, and the first cool roller and the second cool roller, to ensure further the lamination of the two composite materials.
Abstract:
The disclosure relates to a tape laying apparatus configured to lay prepreg tape to mould surface. The tape laying apparatus includes a tape supply spool, a compaction head, a cutting tool and at least one travel distance adjustment component. The tape supply spool is configured for the prepreg tape to be wound thereon. The compaction head is configured for delivering the prepreg tape to the mould surface from the tape supply spool. The cutting tool is movable along a cutting path. The cutting tool is configured to cut the prepreg tape passing through the cutting path. The at least one travel distance adjustment component is movably located between the cutting path and the compaction head and configured to push the prepreg tape passing through the cutting path so as to increase or decrease a travel distance of the prepreg tape from the cutting path to the compaction head.
Abstract:
An embodiment of the invention provides a compound barrier layer, including: a first barrier layer disposed on a substrate; and a second barrier layer disposed on the first barrier layer, wherein the first barrier layer and second barrier layer both include a plurality of alternately arranged inorganic material regions and organo-silicon material regions and the inorganic material regions and the organo-silicon material regions of the first barrier layer and second barrier layer are alternatively stacked vertically.
