A tire (10) having a decoration region (2) arranged on the surface (1) of at least one of a pair of sidewalls and consisting of a pattern portion (3) and an emblem portion (4) in which a degree of freedom in arrangement of the emblem is enhanced markedly and visibility of the emblem can be improved significantly relative to the pattern. Pattern of the pattern portion (3) is constituted of a first ridge group (15A) consisting of ridges (5A) extending in parallel to each other, and a second ridge group (15B) consisting of ridges (5B) extending in parallel to each other in the direction different from that of the ridges (5A). Emblem of the emblem portion (4) is constituted of a plane parallel with the sidewall surface (1) or by combining a plurality of these planes, wherein the maximum height of the emblem portion (4) with respect to the sidewall surface level is set higher than the maximum height of the pattern portion (3).

The invention provides a display panel. The display panel comprises a backboard, a cover board, a first spacer and a second spacer, wherein the backboard is provided with a first surface; the cover board is arranged opposite to the backboard and is provided with a second surface opposite to the first surface; the first spacer is arranged on the edge of the first surface in a protruding mode, is ofa closed structure and is provided with a first free end which is connected to a first connecting end of the backboard and extends away from the backboard; the second spacer is arranged on the edge of the second surface in a protruding mode, is of a closed structure and is provided with a second free end which is connected to a second connecting end of the cover board and extends away from the cover board; and the first free end abuts against the second free end.

The invention discloses a middle island type extractor hood. The middle island type extractor hood comprises a body (1) and a cooking fume collecting cavity (2) arranged at the lower end of the body (1), the lower end of the cooking fume collecting cavity (2) is provided with a strip-shaped cooking fume collecting port, and the middle island type extractor hood is characterized in that the two ends of the cooking fume collecting port extend downwards to be provided with baffles (21); and the extractor hood further comprises two cooking fume gathering plates (3) and a driving mechanism, the twocooking fume gathering plates (3) are arranged on the two sides of the cooking fume collecting port in a turning mode, and the driving mechanism is in driving connection with the cooking fume gathering plates (3). When the extractor hood is in a working state, the driving mechanism drives the two cooking fume gathering plates (3) to be opened mutually, and the baffles (21) and the cooking fume gathering plates (3) jointly form a cooking fume gathering area in a surrounding mode; and when the extractor hood is in a work completion state, the driving mechanism drives the two cooking fume gathering plates (3) to be closed mutually. The overall structure is compact, and therefore the cooking fume gathering effect and the overall visuality are perfectly combined.

The present application may provide a laminated film comprising a retardation layer exhibiting blocking characteristics against a specific ultraviolet ray even when no ultraviolet absorber or light stabilizer is mixed therein. In addition, the present application may provide a laminated film which: exhibits a constant UV blocking property even in the absence of a UV absorber or light stabilizer, and is thus used alone or in combination, as necessary, with an appropriate UV blocker or light stabilizer; selectively blocks ultraviolet rays in areas requiring blocking without affecting display performance such as color and image quality of a display device; does not need a separate ultraviolet blocking layer and thus may be thinly formed; and has excellent durability.

Disclosed are an alignment material composition, a planarisation material composition, a liquid crystal display device, and a method for adjusting the display colour of the liquid crystal display device. The alignment material composition or planarisation material composition respectively comprises 0.5-20wt% of an organic additive, and the organic additive is selected from one or more of a spiropyran compound, a Schiff base compound, and a heterocyclic diarylethene compound. Adding the above-mentioned organic additive to the alignment layer or planarisation layer of a liquid crystal display device enables adjustment of the display colour in a relatively large colour range without influencing other display performances of the liquid crystal display device.

The present application relates to a polarizing plate and a display comprising the same. The present application may provide a polarizing plate including a retardation layer exhibiting an ultravioletblocking property even in a state where no ultraviolet absorber or light stabilizer is blended therein. In addition, the present application may provide a polarizing plate which: exhibits a constant ultraviolet blocking property even in the absence of a ultraviolet absorber or light stabilizer and thus can selectively block ultraviolet rays in an area that needs to be blocked, by the polarizing plate alone or in combination with an appropriate ultraviolet screening agent or light stabilizer as necessary, without affecting display performance of a display device, such as color and image quality; and requires no separate ultraviolet blocking layer and thus not only can be formed thin but also has an excellent durability.

The invention discloses an easy-to-clean polypropylene composite material for a see-through rice cooker, a preparation method and an application. The composite material is composed of, by mass, 30-80% of high-crystallized homo-polypropylene, 1-20% of transparent filler masterbatches, 0.5-10% of polytetrafluoroethylene micro powder, 10-40% of nano-silica masterbatches, 0.1-0.5% of hindered phenolic antioxidants, 0.1-1% of phosphorated antioxidants, 0.1-1% of thioester antioxidants and 0.1-2% of lubricating agents. The components are mixed evenly and then added in a parallel twin screw extruder to be blended, melted and extruded to obtain the composite material. The composite material has the advantages of resisting high temperature and long-term thermo-oxidative aging, being easy to form and excellent in comprehensive physical and mechanical performance and the like, and can be applied to the field of small household appliances such as rice cookers, pressure cookers, induction cookers and soybean milk machines.

The invention discloses a method of realizing information display and encryption based on femtosecond laser-induced segmentation patterns. The method comprises the following steps: firstly, a metal film on which Ti and Au are sequentially deposited on a glass substrate is taken as a processing object; secondly, a light path is built, and a computer is used to adjust a femtosecond laser device to output laser, wherein the laser wavelength is 1030 nm, the pulse width is 240 fs, the repetition frequency is adjustable within 1-200 kHz, and the maximum monopulse energy is 200 muJ; a sample is thenfixed on a processing station of a shear type lifting platform, the laser energy, a scanning speed and a scanning distance are adjusted, the pattern is equally segmented by 100 mum, and respectively laser-induced periodic surface structures LIPSSs of which the directions are vertical to each other are prepared in the segmented adjacent areas. According to the method, the LIPSSs perpendicular to each other in directions are prepared in the adjacent areas of the segmented pattern through femtosecond laser induction, the information display range is expanded, and information encryption is achieved.
