The objective of the invention is to provide an adhesion-prevention plate used for a vacuum film-forming device, a manufacturing method of the plate, a vacuum film-forming device adopting the adhesion-prevention plate and a vacuum film forming method, wherein the adhesion-prevention plate has good stripping preventing effects of a film forming material in a repeated evaporation circumstances. The adhesion-prevention plate is used for preventing adhesion of the film forming material to an unneeded position in the vacuum film-forming device, is made of aluminum, and comprises a surface of a concave-convex structure having concave parts with an average opening diameter being 0.01-9 [mu]m. A plurality of convex parts having an average height of 30-1000 [mu]m are arranged on the surface. The average density of the convex parts is higher than 10/10 mm<2>. The ratio of the bottom area of the convex parts is larger than 90% in a square area having a size of 10 mm.

The invention relates to a high efficient filter bag dust separation device which has high efficient dust removal effect with low energy consumption.

In the flat cloth bag filtering device, a plurality of flat cloth bags which form the flat cloth bag collection are internally provided with flat cloth bag separating plates, the double faces of which take concavo-convex structure. The dust cleaning mechanism is composed of an eccentric vibratory mechanism, a connection rod, a socket connecting piece, a connecting piece, a connecting plate and a threaded rod. The end surface of the eccentric vibratory mechanism is connected with one end of the connection rod; the other end of the connection rod is connected with the socket connecting piece; the connecting plate is connected with the socket connecting piece by the connecting piece; the threaded rod is screwed on the connecting rod and is connected with the connecting plate in a revolving way; the rectangle frame of the filter bag frame is composed of a left rack, a right rack, a front rack and a rear rack; wherein, the lower end surfaces of the left rack and the right rack are respectively provided with a groove profile guide way and the notches of the two groove profile guide way are opposite.

The invention discloses a spontaneous combustion type fire extinguishing bullet for fire protection. The fire extinguishing bullet comprises a sealing cover, external containers and an internal container, wherein the sealing cover adopts a sleeve structure and is divided into an inner ring and an outer ring; threads are arranged on the inner walls of both the inner ring and the outer ring of the sealing cover; a sliding chute is formed in the inner wall of the top end of the external container I; a puncture sharp knife is arranged at the top end of the interior of the external container II; asolution and powdery substance which produces chemical reaction with the solution and produces carbon dioxide are correspondingly contained in the internal container and the external container II respectively; a sealing ring I is arranged at the tail end of the external container II; the sealing ring I adopts a convex structure; the side wall of the upper part of the sealing ring I is fixed on theouter wall of the internal container through a plastic screw. The fire extinguishing bullet is simple in designed structure, easy to carry, easy to operate and high in safety index, cannot cause damage to human body, buildings and other furniture and equipment during explosion, and only achieves extinguishment effect on fire sources.

The invention discloses an efficient metal reflection type heat preservation material. The material comprises a plurality of layers of stainless steel foils arranged in parallel; each stainless steel foil is provided with a concave-convex structure; the concave-convex structures of every two adjacent stainless steel foils are arranged in a staggered mode; at least one face of each stainless steel foil is provided with a high-reflection porous coating; each high-reflection porous coating is provided with an open pore structure extending from the interior of the coating to the surface of the coating, and the heat reflectivity of the high-reflection porous coating is larger than or equal to 0.9. According to the heat diffusion principle, the porous structure of the high-reflection coating on the surface of each stainless steel foil is designed, so that heat can be effectively prevented from spreading from gaps between the stainless steel foils. The high-reflection porous coatings can effectively reflect heat radiation, the heat reflectivity of the high-reflection porous coatings is larger than or equal to 0.9, and the heat insulation effect can be achieved.

The invention provides an alignment method of a photoetching process. The method comprises the following steps: providing a base which comprises a substrate, a first functional pattern, an alignment mark and a filling medium which are formed on the substrate, the upper surfaces of the first functional pattern, the alignment mark and the filling medium being in a first plane; forming a groove in the outer side of the alignment mark, and forming an opening of the groove in the first plane; forming a second functional layer on the first plane, the second functional layer forming a conformal topological structure on the groove; and detecting the alignment mark according to the conformal topological structure, and completing photoetching and etching of the second functional layer. According tothe invention, the concave-convex structure is formed around the alignment mark, and the conformal topological structure is formed on the second functional layer, so that the position of the alignmentmark under the opaque film can be identified through the conformal topological structure, and accurate photoetching alignment is realized.

The invention relates to hollow flower and strip stock quick-drying washable fabric with a breathable layer. The hollow flower and strip stock quick-drying washable fabric comprises hollow flower parts (1) and colored strip parts (2). The hollow flower parts (1) and the colored strip parts (2) are in strip shapes, of the same width and connected in a staggered and parallel mode in the same plane to form a concave-convex structure. The hollow flower parts (1) are made of fabric which is formed by interweaving warp and weft. The warp and the weft are each covering yarn of cotton-wrapped polyester filament yarn. The cross section of the polyester filament yarn is in a pentacle shape. By means of the concave-convex structure, the stereoscopic impression of the hollow flower and strip stock quick-drying washable fabric with the breathable layer is enhanced.
