  • Publication number: 20240382895
    Abstract: A facility for treating gas includes a flow channel providing a passage through which a waste gas flows; a thermal decomposition unit for thermally decomposing the waste gas flowing through the flow channel; a quencher for cooling the waste gas passed through the thermal decomposition unit to a predetermined temperature; and a cooling chamber in communication with the flow channel such that the waste gas passed through the quencher is introduced into the cooling chamber, the cooling chamber accommodating a solid material for cooling therewithin.

  • Patent number: 11985754
    Abstract: A gas treating apparatus may include a reaction chamber configured to process a gas supplied from an outside by a plasma, the processed gas containing a nitrogen oxide, and a nitrogen oxide reduction apparatus connected to the reaction chamber. The nitrogen oxide reduction apparatus includes a cooling unit configured to cool the processed gas to a temperature lower than a nitrogen oxide generation temperature.

  • Patent number: 11430638
    Abstract: A plasma generating apparatus may include a cathode assembly including a cathode, an anode assembly including an anode having therein a plasma generation space, and one or more magnetic force generators configured to generate a magnetic force. The anode assembly has one end portion in which a gas supply path is provided and the other end portion having an opening, the gas supply path configured to supply a plasma generating gas to the plasma generation space. The gas supply path is configured to generate a vortex of the plasma generating gas in the plasma generation space and said one or more magnetic force generators are arranged such that the magnetic force is generated in a direction opposite to a rotational direction of the vortex of the plasma generating gas.

  • Publication number: 20110213804
    Abstract: Disclosed herein is a system structure for extracting relations between technical terms within a large amount of literature information using verb-based patterns. The present invention provides a system that is capable of extracting relations based on verb-based patterns from abstract and bibliography databases in all fields of science and technology using a Tech Association Mining Appliance (TAMA) capable of detecting the technical terms of text and relations therebetween in academic literature databases in the fields of science and technology. The present invention has an advantage of providing a practical relation extraction system structure using a number of academic databases.

  • Publication number: 20110208776
    Abstract: The present invention relates to a method and apparatus for extracting the semantic relations of context and a recording medium storing the program source thereof. The present invention is intended to detect technical terms by parsing full text of documents and recommend research topics using the relations therebetween using a method of searching for a first concept connected to a specific vocabulary word through a casual relationship and a second concept connected to the first concept through a causal relationship, determining the relation therebetween and performing recommendation as research topics. The present invention has the industrial utilization advantage of improving the overall search efficiency and utility of massive databases.
