Abstract: A stamping tray includes a tray body and a base board. The tray body defines a number of mounting grooves for receiving workpieces to be scrapped. The base board is located on a side of the tray body away from the mounting grooves. Each of the mounting grooves defines a through hole extending to the base board.

Abstract: A use of zwitterionic compound in preparation of dynamic-scattering-mode-based liquid crystal material. A liquid crystal material is also described. Such material contains liquid crystal and dopant, and the dopant is zwitterionic compound. A liquid crystal electro-optical device comprising such liquid crystal compound and the use of such optical device are also described. Zwitterionic compound is used as dopant to induce a stable dynamic scattering mode in liquid crystals.

Abstract: An automatic analysis apparatus and an operating method for the automatic analysis apparatus. At least two magnetic separation units are introduced, each magnetic separation unit operating independently and being used for performing magnetic separation cleaning on a reaction solution in a reaction cup. Each magnetic separation unit may be used for any magnetic separation cleaning step in a one-step test project or a multi-step test project, thereby significantly increasing the test speed and the test throughput of the automatic analysis apparatus.

Abstract: The present invention has particular applicability for packaging products and relates to an anti-theft box with a lock mechanism that includes an inner box, with an opening at the first end, a cover plate at the second end and a limiter on the outer wall, and the first end is opposite to the second end; and an outer box. The outer box forms a space, the inner box is installed in this space, the cover plate is outside this space, a locating part is installed on the inner wall of the outer box, and the limiter and the locating part are used in combination to prevent the inner box from being separated from the outer box. The advantage of the present invention is that the safety device in the anti-theft box must be opened to open the anti-theft box to confirm whether the box has been opened.

Abstract: The present disclosure describes methods, devices, and storage mediums for adjusting computing resource. The method includes obtaining an expected pooling time of a target pooling layer and a to-be-processed data volume of the target pooling layer; obtaining a current clock frequency corresponding to at least one computing resource unit used for pooling; determining a target clock frequency according to the expected pooling time of the target pooling layer and the to-be-processed data volume of the target pooling layer; and in response to that the convolution layer associated with the target pooling layer completes convolution and the current clock frequency is different from the target clock frequency, switching the current clock frequency of the at least one computing resource unit to the target clock frequency, and performing pooling in the target pooling layer based on the at least one computing resource unit having the target clock frequency.

Abstract: A method of generating content information that matches at least one stored keyword is described. At least one keyword associated with content information is stored. At least one previously searched keyword in a search record is matched with the at least one stored keyword associated with the content information. First-category mapping data is generated based on a first mapping between the matched at least one stored keyword and the at least one previously searched keyword. Second-category mapping data is generated based on the content information and the at least one stored keyword. A received target keyword is determined to be included in the first-category mapping data. In response to the received target keyword, which is included in the first-category mapping data, circuitry of a terminal searches for the content information associated with the target keyword in the second-category mapping data and displays the content information.

Abstract: A plate folding and unfolding device and a solar panel structure are provided. The plate folding and unfolding device includes a cam fixed with first plate piece, and a rotating shaft is disposed inside the cam in an axial direction of the cam; a connecting rod, where the connecting rod includes a first end and a second end that are opposite to each other, the first end is connected vertically to the rotating shaft, and the second end is fixed to a second plate piece; a positioning shaft, where the positioning shaft is disposed, on the connecting rod; and an elastic piece, where the elastic piece is disposed on the connecting rod, one end of the elastic piece is connected to the positioning shaft, where a groove that accommodates the positioning shaft is disposed at at least one location of the outer peripheral surface of the cam.

Abstract: The present disclosure provides an antibacterial hydrophilic compound. The antibacterial hydrophilic compound may react, induced by light through a hydrogen abstraction group in the structural formula thereof, with a C—H group and thus bind to a surface of a material having the C—H group (for example, chemical fibers such as polyester, chinlon, and the like; plastics, rubbers, and other similar materials), which can impart a durable antibacterial activity and hydrophilicity to the material. The antibacterial hydrophilic compound has a relatively strong binding force to the surface of the material without damaging the mechanical properties of the raw material. The present disclosure also provides a modified material that is modified by the antibacterial hydrophilic compound.
