Abstract: A semiconductor device and a manufacturing method therefor. The semiconductor device comprises: a semiconductor substrate. A first drift region is formed in the semiconductor substrate. A gate structure is formed on the semiconductor substrate A part of the gate structure covers a part of the first drift region. A first trench is formed in the first drift region, and a drain region is formed in the semiconductor substrate at the bottom of the first trench.

Abstract: A manufacturing method for a P-type laterally diffused metal oxide semiconductor device includes: forming a N-type buried layer in a substrate, forming a P-type region located on the N-type buried layer, and forming a mask layer located on the P-type region; patterning the mask layer to form at least two injection windows; performing N-type ion implantation by the at least two injection windows; forming an oxide layer; removing the mask layer; performing P-type ion implantation on the P-type region to form a P-type doped region; diffusing the P-type doped region to form a drift region and two P-type well regions, diffusing the high-voltage N-well doped region to form a high-voltage N-type well region, and diffusing the low-voltage N-well doped region to form a low-voltage N-type well region; and forming a source doped region, a drain doped region, and a gate.

Abstract: A method for extracting germanium based on acid decomposition is provided, including acid decomposition and post-treatment steps, and specifically including: adding an acid to a coal ash for conditioning to obtain a material a; heating the material a to 350° C. to 800° C., and keeping the material a at this temperature for 10 min to 10 h to obtain an acid-decomposed material b; milling the acid-decomposed material b until more than 60% of a milled material has a particle size of less than 200 mesh to obtain a material c; subjecting the material c to distillation to obtain a residual slurry d and a distillation fraction e; and hydrolyzing the distillation fraction e with a dilute hydrochloric acid solution, and then oven-drying to obtain GeO2.

Abstract: One embodiment of the present invention sets forth a technique for performing a virtual try-on task. The technique includes determining a dense pose associated with a first figure depicted in a first image. The technique also includes converting, based on the dense pose, a second image of a first garment into a third image of a first warped garment. The technique further includes inputting the dense pose, one or more regions of the first image, and the third image of the first warped garment into a first neural network and generating, via execution of the first neural network, an output image that depicts the first figure wearing the first garment.

Abstract: The present invention relates to a vertical floor self-locking musical instrument stand and a self-locking hook. The vertical floor self-locking musical instrument stand is provided with a plurality of folding structures, which can facilitate telescopic storage and reduce the occupied space. The telescopic length can be changed as needed to be portable. Various components are flexibly connected and assembled. The height of the position can be adjusted as needed. The stand is equipped with a folding anti-collision component and a self-locking hook, which can better protect the musical instrument and prevent the musical instrument from bumping or falling. When the musical instrument is suspended on the self-locking hook, the self-locking hook automatically locks the self-locking locking arm under the gravity of the musical instrument itself, providing protection for the musical instrument suspended thereon.
