[Item use] The designed item is used as an operating member of a fishing reel. [Design description] In the drawing, the part filled with red color is not claimed in the design. The difference between the original designed item and the present design is that the concave-convex spiral direction provided on the outer circumferential surface of the slightly cylindrical body is right-handed or left-handed.

This invention discloses a red pigment paste for color photoresist and its preparation method, relating to the field of photoresist technology. The red pigment paste for photoresist comprises the following materials: modified pigment red 177, propylene glycol methyl ether acetate, poly(methacrylic acid-co-acrylate) copolymer, acrylate resin, styrene-maleic anhydride copolymer, and antioxidant. This invention, by adding modified pigment red 177, works synergistically with the poly(methacrylic acid-co-acrylate) copolymer and polydimethyldiallyl ammonium chloride to inhibit pigment particle agglomeration, ensuring uniform dispersion of the pigment in the propylene glycol methyl ether acetate solvent, thus guaranteeing uniform and fine dispersion of the pigment paste. The antioxidant in this invention includes β-cyclodextrin, which can coat pentaerythritol tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate] and UV-327, improving the compatibility of the pigment paste system and extending the storage life of the pigment paste.

A projector. In the projector, color breakup is reduced while color gamut and luminance are taken into account. The projector includes a first light source device that emits first color light, a first liquid crystal panel that has a plurality of rows, and a first light scanning device that scans the first color light in a column direction. In each of a plurality of subframes included in one frame, a voltage corresponding to different color data is written to each row or each multiple row from a first row toward a last row, the first color light is scanned from the first row toward the last row, red color light is emitted from the first light source device as the first color light during a period in which a voltage corresponding to red color data is written, green color light is emitted from the first light source device as the first color light during a period in which a voltage corresponding to green color data is written, and blue color light is emitted from the first light source device as the first color light during a period in which a voltage corresponding to blue color data is written.

The present invention provides a first-agent hair dye composition that dyes light-colored hair a vivid primary red color, exhibiting high red color saturation and excellent colorfastness. [Solution] A first hair dyeing agent composition containing one or more selected from (A) 1-hydroxyethyl-4,5-diaminopyrazole, (B) 2,6-diaminopyridine, and (C) 5-(2-hydroxyethylamino)-2-methylphenol or m-aminophenol, wherein the mass ratio of component (C) to component (B) [(C) / (B)] is 0.10 to 0.80.

The present application relates to the field of color paste, in particular to a kind of high stability brown color paste and preparation method thereof.High stability brown color paste, its preparation raw material is according to mass fraction, including 60-80 parts epoxy resin, 1-3 parts dispersing agent, 0.3-0.5 parts defoaming agent, 20-30 parts red color powder, 5-10 parts yellow color powder, 1-3 parts black color powder;Wherein dispersing agent includes polyether modified polydimethylsiloxane organosilicon surfactant YCK-2904 or high molecular weight copolymer YCK-2320 with pigment affinity group.The present application effectively solves the problem of high viscosity, poor storage stability, easy to float color and flower of traditional brown epoxy color paste, viscosity is stable within 15 days at 60 ℃ high temperature, no pigment flocculation phenomenon, and raw material compatibility is good, preparation process is simple, adapt to the coloring demand of solvent-free industrial paint, automobile paint, furniture paint, and the industrial application prospect is good.

The application discloses a trolley tracking method based on a mobilenet V2 model and a gray difference ratio, and the trolley tracking method can recognize routes of various color lines as long as the target tracking route and the environmental background color difference are obvious, for example, a white color is used as a bottom plate, and routes of black color, blue color and red color can be well recognized, and when a cross road or a T-shaped road is faced, an identification can be automatically recognized, and it is judged that the next step is left turning, right turning or straight going. The tracking method has strong anti-interference ability and small calculation amount of tracking, can adapt to various scenes and illumination conditions, and has high flexibility.
