  • Patent number: 9399212
    Abstract: The present invention relates to a method for producing an anhydrosugar alcohol and, more specifically, to a method for producing an anhydrosugar alcohol which, when the step of subjecting a hydrogenated sugar to a dehydration reaction in a reactor so as to convert same to an anhydrosugar alcohol is performed, allows the hydrogenated sugar to be continuously introduced into the reactor and the produced anhydrosugar alcohol to be continuously discharged out of the reactor while the dehydration reaction is carried out, also prevents a reaction mixture from circulating inside and outside the reactor while the dehydration reaction is carried out, and thereby can significantly improve production efficiency compared with a conventional process adopting a batch or semi-batch-type dehydration reaction and thus can be appropriately applied particularly to a large-scale anhydrosugar alcohol production process.

  • Patent number: 9299542
    Abstract: A method of monitoring a manufacturing process includes generating a measurement data by analyzing emission intensity of plasma emission light using a measurement device, the plasma emission light being generated when a plasma gas of a manufacturing process device is changed from an energy level corresponding to a high energy state to an energy level corresponding to a low energy state, generating a compensated value based on the measurement data, the compensated value being generated by offsetting a sensitivity change that is caused due to pollution of the manufacturing process device and the measurement device or measurement locations of the measurement device, and monitoring the manufacturing process based on the compensated value.

  • Patent number: 9183950
    Abstract: A memory card includes a memory cell, a connector, a controller, and firmware. The memory cell can switch between a plurality of states. The connector can be connected to an external device and exchange signals including commands and data with the external device. The controller exchanges signals with the connector, analyzes a received signal, and accesses the memory cell to record, retrieve or modify data based on the analysis result. The firmware is located within the controller, controls the operation of the controller, and can be set to a test mode or a user mode. When the firmware receives a test command from the external device and the firmware is set to the test mode, the firmware performs a defect test on the memory cell and transmits the result of the defect test to the external device through the connector.
