2results about How to "Applicable quality control" patented technology

The application relates to the technical field of traditional Chinese medicine, and particularly provides a characteristic spectrum of a Shuangge anti-diarrhea preparation and a construction method thereof. The application adopts a multi-wavelength switching technology by screening a sample processing method and optimizing chromatographic conditions, and simultaneously characterizes main efficacy components of six medicines in a prescription. The method can evaluate the overall curative effect of the Shuangge anti-diarrhea preparation from a qualitative point of view, and significantly improves the quality control level of the Shuangge anti-diarrhea preparation.

The invention discloses a non-parallel workpiece form and location tolerance detector and a detection method thereof. The detector comprises a programmable micro numerical control system, a reference plane precision regulation and control module, a three-dimensional rack multi-axis linkage module, a stepping motor driver module, an output type digital display dial indicator module and a data processing and interaction module. The programmable micro numerical control system is in signal connection with each module and is used for commanding linkage; the reference plane precision regulation and control module is adjusted to a preset angle through closed-loop control to bear and fix a workpiece; the three-dimensional rack multi-axis linkage module comprises a three-axis linkage structure and drives a dial indicator module at the lower end of a Z axis to scan the surface of a workpiece and collect data; the stepping motor driver module drives each stepping motor to operate; collected data is transmitted to the data processing and interaction module for analysis. According to the invention, high-precision automatic detection of the form and location tolerance of the non-parallel workpiece can be realized, the measurement stability and precision are high, manual errors can be eliminated, the efficiency is improved, the cost is reduced, and the method is suitable for quality control in the manufacturing industry.
