Abstract: A shape follow-up support device for selective laser melting and a method thereof are provided. The device includes a lifting base, where the lifting base is provided with an inner cavity, and a top wall of the lifting base is provided with multiple first through holes communicated with the inner cavity of the lifting base, and the multiple first through holes are arranged at equal intervals. Multiple driving assemblies are arranged in the lifting base; output ends of the driving assemblies extend out of the lifting base through the first through holes and are provided with support rods, and protruding ends of the support rods are detachably connected with sacrificial assemblies. A porous substrate is provided with multiple second through holes, and the multiple second through holes are in one-to-one correspondence with the multiple first through holes and communicate with the multiple first through holes.

Abstract: This application provides a storage device, a distributed storage system, and a data processing method, and belongs to the field of storage technologies. In this application, an AI apparatus is disposed inside a storage device, so that the storage device has an AI computing capability. In addition, the storage device further includes a processor and a hard disk, and therefore further has a service data storage capability. Therefore, convergence of storage and AI computing power is implemented. An AI parameter and service data are transmitted inside the storage device through a high-speed interconnect network without a need of being forwarded through an external network. Therefore, a path for transmitting the service data and the AI parameter is greatly shortened, and the service data can be loaded nearby, thereby accelerating loading.

Abstract: A rapid cycle pressure swing adsorption (RCPSA) air purification process, apparatus, and device for the removal of at least one of water, carbon dioxide, nitrous oxide, and one or more hydrocarbons from a feed air stream prior to cryogenic air separation.

Abstract: Disclosed herein is a stator plate for a rotary bed PSA apparatus that has an exhaust slot that has first and second sections for receiving blowdown and purge exhaust gas streams, the sections being separated by a flow restriction that restricts but does not full prevent gas flow between the sections, or that has separate exhaust slots for separately receiving the blowdown and purge exhaust gas streams. Also disclosed is pressure swing adsorption (PSA) apparatus including such a stator plate, and a rotary bed PSA process using such an apparatus.
