The invention relates to a horizontal compressor which comprises a shell, a lower flange, an air cylinder, an upper flange and a motor. The lower flange, the air cylinder, the upper flange and the motor are sequentially arranged in the shell. An oil storage cavity is formed by the lower flange and the shell. A rotor is rotationally arranged in the air cylinder through a main shaft. The horizontal compressor further comprises a center oil hole penetrating the main shaft, a radial hole formed in the main shaft and communicating with the center oil hole, an oiling pipe fixedly connected to the end, located in the oil storage cavity, of the main shaft and communicating with the center oil hole, a lower flange back pressure groove formed in the lower flange and communicating with a sliding piece installation groove of the rotor, a groove for communicating the lower flange back pressure groove and the radial hole of the main shaft, an exhaust cavity communicating with an exhaust hole of the air cylinder and the center oil hole of the main shaft, and a fan installed at the other end of the fan, wherein the bottom end of the oiling pipe is close to the bottom of the oil storage cavity. According to the horizontal compressor, smooth stretching-out of a sliding piece during starting of the compressor and attachment between the sliding piece and the air cylinder during normal running of the compressor are effectively ensured. The invention further discloses a temperature adjusting device comprising the horizontal compressor.

The invention discloses a manufacturing process of a metal film screen plate. The manufacturing process of the metal film screen plate includes taking the screen in advance and laying it flat, and then placing the metal film on the transfer film, and attaching the metal film to the metal film after heating. The glue that plays the role of adhesion, and finally heat-press the side of the metal film attached to the glue to the screen, and remove the transfer film; wherein, before the hot-pressing operation, the metal film is engraved to achieve the desired shape. The metal film screen plate is bonded to the screen screen plate by glue to make a printing screen plate, and the metal film screen plate can be produced quickly and efficiently by adopting the process method provided by the invention. The metal film screen plate is resistant to the extrusion of foreign particles during use, and is not easy to wear and tear. It can improve printing stability and production efficiency, reduce printing costs, and has perfect overall functions and strong practicability.

The present invention relates to the technical field of conveying operations, and specifically provides a workpiece transfer system. The system includes a track formed by a plurality of monorails arranged in parallel, and also includes bearing seats for being arranged on different monorails and cooperating with the monorail guides. The bearing seat is provided with a fixing structure for fixing the workpiece placed on the bearing seat to be transferred. The technician can arrange the track along the direction of the processing station for processing the workpiece. When the workpiece and the bearing seat move along the track, the workpiece can be processed along the track and the processing process can be completed at the previous station. After moving to the next station for processing, the efficiency is high; the bearing seat and the workpiece are combined to form a "car" moving on the track, the workpiece becomes the frame, and the bearing seat below the workpiece becomes the wheel. After the transportation is completed, the bearing seat can be directly removed from the workpiece for reuse. The matching form is flexible and the operation efficiency is high.

The invention discloses a frequency offset estimation method, system, electronic equipment and storage medium. The frequency offset estimation method includes: receiving subframe samples of a downlink physical channel; calculating signal power information and interference power information based on the subframe samples; and calculating an estimated frequency offset value based on the signal power information and the interference power information. The present invention weights the disturbing sound factor into the calculation process of the estimated frequency offset value, and adaptively weights the size of the output estimation result through the weight relationship between the signal and the disturbing sound. While improving the confidence of the output result, there is no need to The estimated values ​​undergo additional post-processing, which can be flexibly adapted to various scenarios.

The invention belongs to the field of face recognition, and specifically relates to a method, system, and device for detecting key points of a face based on semantic alignment, aiming at improving the accuracy of key point detection of a face. After the face key point detection network, use the constructed training samples including the face image samples marked with key points and the standard Gaussian response map centered on the position of each key point, and use the probability model containing hidden variables as the maximum The goal of likelihood estimation is then optimized for the face key point detection network; the coordinates of face key points are predicted through the final optimized face key point detection network. The invention effectively overcomes the training shock problem caused by the randomness of labeling in the network training process, and improves the accuracy of face key point detection.
