The invention discloses a flexible panel, a method for manufacturing the flexible panel and a flexile display device. Due to the fact that a buffer layer is insulating and high in thermal conductivity, the insulating function is realized on one hand, and on the other hand, when laser crystallization is conducted on an amorphous silicon membrane on the buffer layer to form a polycrystalline silicon membrane, residual laser energy can still be dissipated quickly through the buffer layer high in thermal conductivity even if laser energy can not be absorbed totally by the amorphous silicon membrane. In this way, damage to a flexible substrate by the residual laser energy is avoided, and the performance of the flexible panel is guaranteed.

The invention relates to a coaxial in-arc wire feeding and out-arc powder feeding TIG electric arc additive manufacturing device.

The invention discloses a feed-through screw connection structure for a generator stator core. The generator stator core is formed by laminating a plurality of core laminations; a feed-through screw passes through a feed-through screw hole of the generator stator core and the plurality of laminated core laminations are pressed and fixed together; an insulating layer prepared from a flexible material is arranged on the periphery of a corresponding segment, in the feed-through screw hole, of the feed-through screw; the diameter of the corresponding segment, provided with the insulating layer, ofthe feed-through screw is not smaller than the aperture of the feed-through screw hole; the feed-through screw is put into the feed-through screw hole; and then the periphery of the insulating layerof the feed-through screw is in contact with a hole wall of the feed-through screw hole. On the basis of an existing feed-through screw structure, the insulating layer prepared from the flexible material is arranged on the periphery of the feed-through screw, and the insulating layer is in contact with the hole wall of the feed-through screw hole, so that multi-point contact of the feed-through screw and the core is achieved to improve the inherent frequency of the screw, the inherent frequency is far away from the vibration frequency of the core, resonance is avoided, and meanwhile, the feed-through screw connection structure plays a screw insulating role.

The invention belongs to the cable technology field and relates to a novel flexible halogen-free flame-retardant fire-prevention cable and a manufacturing method thereof. The cable comprises four layers of structures and is formed by a conductive copper wire core, an insulation fire-prevention layer made of a special rubber / inorganic nano particle hybrid composite material, an inorganic composite band fireproof layer and a halogen-free flame-retardant polymer sheath layer. The insulation fire-prevention layer wraps the conductive copper wire core and the layer carries out extrusion molding through rubber extrusion processing equipment. A fireproof inorganic composite band wraps above the insulation fire-prevention layer so as to form a fireproof layer. And finally, through extrusion processing, the halogen-free flame-retardant polymer sheath layer wraps a periphery of the fireproof layer. Compared to other fireproof cables, the cable of the invention has characteristics that the cable has good flexibility so that the cable can be bended at a large degree; good fireproof fire-prevention performance is possessed; flame-retardant performance is good and a smoke amount is low; during a production process, a length of the cable is not limited; and laying is convenient and cost is low.
