This invention relates to the field of integrated circuits and discloses a mixed-precision in-memory computing circuit, data processing method, and chip. The invention includes: a storage array, an index memory, and a multiply-accumulate calculation circuit. The storage array includes a first data element stored in a first precision format and / or a second data element stored in a second precision format; wherein the bit width of the first precision format is greater than that of the second precision format; the storage locations of the storage array are divided according to the bit width of the second precision format; the first data element occupies multiple consecutive storage locations; the read bit width of the storage array is an integer multiple of the bit width of the first precision format; the index memory stores the position index information of the first data element in the storage array; the multiply-accumulate calculation circuit is used to determine the precision format corresponding to the data read from the storage array based on the position index information, and performs a multiply-accumulate operation corresponding to the precision format, outputting the calculation result. This solves the compatibility problem between mixed-precision data storage and computing circuits.

The utility model relates to the technical field of welding and polishing, and discloses a weld joint polishing treatment device which comprises a portable cylinder, a polishing motor is fixedly arranged at the upper end of the portable cylinder, a polishing plate is fixedly arranged at the output end of the polishing motor, an anti-inclination structure is arranged on the outer wall of the portable cylinder, and the anti-inclination structure comprises a mounting frame fixedly arranged on the outer wall of the portable cylinder. Four movable rods are movably arranged in the mounting frame, a transverse plate is fixedly arranged at the upper ends of the four movable rods, stabilizing pieces are arranged at the lower ends of the four movable rods, and springs are fixedly arranged at the upper ends of the stabilizing pieces located on the outer walls of the movable rods. According to the weld joint polishing treatment device, it can be guaranteed that polishing of the polishing plate is in a stable state, and neatness of a polishing area is guaranteed.

The present application relates to a kind of nitrogen-rich acylhydrazone-based covalent organic framework material and its preparation method and application, to 5'-(4-(hydrazine carbonyl)-3-methoxyphenyl)-3,3''-dimethoxy-[1,1':3',1''-tri phenyl]-4,4''-dicarboxylic dihydrazine, 1,3,5-tri (2-formylpyridine-5yl) Benzene and 4,4',4''-(1,3,5-triazine-2,4,6-triazyl) triphenyl formaldehyde as building unit, synthesis using Schiff base reaction.The nitrogen-rich acylhydrazone-based covalent organic framework material of the present application has good chemical stability, and can be used as carrier by metal coordination effect Palladium nanoparticles are loaded to obtain composite material, and the composite material shows excellent catalytic activity and substrate universality in catalyzing Heck reaction, has potential application value in the field of biological medicine and green chemistry.

The utility model discloses a plane type self-locking handle for a drawer, which belongs to the technical field of furniture parts and comprises a handle frame, a turning cover is arranged in the handle frame, one side of the turning cover is connected with a turning structure, and the lower portion of the turning structure is connected with the bottom wall of the handle frame. According to the plane type self-locking handle for the drawer, the turnover structure drives the turnover cover to automatically turn over and keep vertical, the turnover cover is embedded in the handle frame to form a plane structure, and therefore a hidden handle structure can be formed, the overall attractiveness is guaranteed, and the problem of dust accumulation is not prone to occurring; the inclined plane of the adjusting lock catch and the inclined plane of the fixed lock catch extrude to enable the adjusting lock catch to move upwards and pass through the fixed lock catch smoothly, then the spring drives the piston to reset downwards, the adjusting lock catch and the fixed lock catch are locked, the purpose of self-locking of the drawer is achieved, in the opening process, the flip cover needs to be pushed open, the air bag needs to be pressed, and therefore the function of preventing children from opening the drawer by mistake can be achieved.
