  • Publication number: 20240002967
    Abstract: The present disclosure relates to a hot working method for stainless steel bars, comprising: step (1) heating a steel ingot at a heating temperature in a range from 1200° C. to 1270° C.; step (2) subjecting the heated steel ingot to radial forging and cogging down according to a total compression ratio greater than 3 to obtain a square billet; step (3) heating the square billet at a heating temperature in a range from 1200° C. to 1270° C.; and step (4) subjecting the heated square billet to hot rolling to obtain a bar. The processing method of the present disclosure can avoid the quality defect of surface crack while ensuring production efficiency by optimizing the process flow and controlling key process parameters, so that niobium-containing high-alloy austenitic heat-resistant stainless steel bars with good surface quality and structure can be prepared.

  • Patent number: 11686637
    Abstract: A silicon carbide-based micro-electro-mechanical system (MEMS) combined temperature-pressure sensor chip and a preparation thereof. The chip includes a peripheric pressure-measuring unit and a center temperature-measuring unit. The pressure-measuring unit includes a silicon carbide substrate with a raised island and a pressure sensitive diaphragm formed by etching the back of the substrate. The raised island and the pressure-sensitive diaphragm constitute a membrane-island structure. Four piezoresistive strips are arranged symmetrically along a circumferential direction of a root of the pressure-sensitive diaphragm and between the raised island and the pressure-sensitive diaphragm. The temperature-measuring unit includes the raised island and a thin-film thermocouple arranged thereon.

  • Publication number: 20220097637
    Abstract: An occupancy detection system consists of a master controller for a series of joined receivers consisting of reader modules and transponder modules in close proximity to one another. The reader modules are able to both send power to the transponder modules wirelessly and receive signals from the transponder modules, where the transponder modules are sending signals based on information received from buckle sensors, occupancy sensors, or both. The transponder modules, set in each seat of the vehicle, will get the latch/unlatch signals from the buckles, and send this information back through the reader modules to the main controller. The main controller will interface with the vehicle to provide user interface notifications.
