134 results about "Spider web" patented technology

A spider web, spiderweb, spider's web, or cobweb (from the archaic word coppe, meaning "spider") is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.. Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber from Sussex, southern England.

Standard spider-web fractal networking method for low voltage power line communication

The invention provides a standard spider-web fractal networking method for low voltage power line communication, and relates to a standard spider-web fractal networking technology for low voltage power line communication. The standard spider-web fractal networking method for low voltage power line communication solves the problem that a current networking method has the disadvantages of being low in the networking efficiency, being low in the reliability and being low in survivability. The method comprises: a main node distributes two time slots for the main node, and then in the first time slot, the main node corrects the frequency offset between the main node and slave nodes. In the second time slot, the main node sends a data frame allowing registration of nodes to the slave nodes within the communication range. When the nodes register successfully, the main node can give a response. In a convergence area, the main node stores the registered slave nodes in a topology table and distributes TEI for the slave nodes. When the convergence process completes, the main node distributes time slots for the registered slave nodes, and the slave nodes which acquire the time slots can perform networking according to the distribution sequence of time slots. The standard spider-web fractal networking method for low voltage power line communication is suitable for a low voltage power line communication field.

Aluminum-based coating and preparation method thereof, and aluminum alloy composite material prepared from aluminum-based coating and preparation method of aluminum alloy composite material

The invention discloses an aluminum-based coating and a preparation method thereof, and an aluminum alloy composite material prepared from the aluminum-based coating and a preparation method of the aluminum alloy composite material. The aluminum-based coating is prepared from Ni-SiC powder, aluminum alloy powder, Al-Si-Cu powder and an organic silicon resin adhesion agent. The preparation method of the aluminum-based coating includes the steps that after raw material powder are mixed, the organic silicon resin adhesion agent is added for repeat-rolling, and the aluminum-based coating is obtained. The aluminum alloy composite material prepared from the aluminum-based coating comprises an aluminum alloy substrate and the aluminum-based coating covering the surface of the substrate. The preparation method of the aluminum alloy composite material includes the steps that the aluminum-based coating is tightly attached to the surface of a pretreated aluminum alloy to be subjected to a brazingreaction. The aluminum-based coating is made of a flexible fibrous metal material, and metal fibers in the coating form a crisscrossed three-dimensional spider-web type structure; the aluminum-basedcoating and a substrate material are subjected to brazing compound, the forming effect is excellent, the bonding strength is high, and wear resistance and the hardness of the surface of the substratematerial can be effectively improved; and in addition, the preparation method is simple and convenient, and safe and environmental friendly.

Temperature-controllable heating disc with spider-web-shaped surface structure

The invention relates to a temperature-controllable heating disc with a spider-web-shaped surface structure. The temperature-controllable heating disc comprises a heating disc with a central gas inlet; a spider-web-shaped trench structure is designed on the surface of the heating disc; and gas recovery holes are formed at the edge of the heating disc, wherein the spider-web-shaped trench structure is composed of N gas flowing annular trenches and N gas flowing radial trenches which are arranged at the center of the heating disc, wherein the annular trenches are connected and communicated with the gas flowing radial trenches. According to the temperature-controllable heating disc with the spider-web-shaped surface structure of the invention, a certain air gap can be formed between the surface of the heating disc and wafers through adopting the air incoming channels; and a heat conduction gas with an excellent heat conduction effect is led into the air gap so as to be adopted as a heat transfer medium, and can fast transfer heat passing through the heating disc to the wafers or fast transfer heat on the waters to the heating disc to lead out the heat. The structural design of the surface of the heating disc is reasonable, so that the heat conduction medium can flow in the gap fast and evenly, so that heat exchange between the heating disc and the wafers can be realized timely.

Fingerprint identification electronic equipment with display screen

The invention provides fingerprint identification electronic equipment with a display screen, belongs to the technical field of fingerprint identification electronic equipment, and aims to solve the problems that heat dissipation holes are usually formed in the rear side of the existing fingerprint identification electronic equipment to help internal electronic elements to dissipate heat, and a large amount of sundries such as spider webs easily block the heat dissipation holes during long-time use, and staff cannot make fingerprint identification electronic equipment automatically clean itself when a fingerprint is identified. The fingerprint identification electronic equipment cleaning device comprises a main body, and the rear side of the main body is connected with a mounting plate ina sliding manner. When a worker carries out fingerprint identification, firstly, a sealing blocking door needs to be opened, a pull rope drives a cleaning brush to move rightwards while the sealing blocking door is opened, and then after the sealing blocking door is loosened, the cleaning brush rebounds leftwards to the original position under the action of the spring, so that the strip-shaped heat dissipation holes formed in the rear end face of the main body are effectively cleaned; and the fingerprint identification electronic equipment can be automatically cleaned, so that the service lifeof the fingerprint identification electronic equipment is prolonged.
