Patent number: 11970566Abstract: Disclosed is a method of manufacturing a polyurethane filter foam having excellent air permeability, elasticity, and restoring force. In the method of manufacturing the polyurethane filter foam, the cell size of the filter foam is made regular by controlling the pressure by adjusting the diameter of the foaming head of a foaming machine, rather than adding a cell opener, cell irregularity caused by poor dispersion of the cell opener is alleviated, and air permeability, porosity, and compression set are excellent.Type: GrantFiled: September 30, 2022Date of Patent: April 30, 2024Assignees: HYUNDAI TRANSYS INC., CHIN YANG CO., LTD.Inventors: Jae Yong Ko, Seung Keon Woo, Young Tae Cho, Won Sug Choi, Sung Yoon Lee, Jae Kwang Lee, Jun Ho Song

Publication number: 20240118607Abstract: The inventive concept provides a substrate treating method. The substrate treating method includes pre-treating a substrate by cleaning the substrate; etching the substrate by supplying an etchant and heating a substrate supplied with the etchant; and post-treating the substrate after the etching the substrate, and wherein the pre-treating the substrate, the etching the substrate, and the post-treating the substrate are each performed in different chambers, a substrate on which the pre-treating the substrate is completed is transferred in a dry state to a chamber at which the etching the substrate is performed, and a substrate on which the etching the substrate is completed is transferred in a wetted state with a liquid to a chamber at which the post-treating the substrate is performed.Type: ApplicationFiled: March 14, 2023Publication date: April 11, 2024Applicant: SEMES CO.,LTD.Inventors: Hyun YOON, Ki Hoon CHOI, Seung Un OH, Young Ho PARK, Sang Hyeon RYU, Tae Hee KIM, Sang Gun LEE

Patent number: 8268034Abstract: Provided is a manufacturing method of ferromolybdenum from molybdenite concentrate, and more particularly, a manufacturing method of ferromolybdenum with copper content of 0.5% or less from molybdenite with high copper content without carrying out a separate copper removing process by putting molybdenite, aluminum metal and iron metal, in a heating furnace and reacting them at high temperature to manufacture the ferro molybdenum at the lower portion thereof, forming a slag using aluminum sulfide and iron sulfide as the main components at the upper portion thereof, and putting most of the copper (80 to 95%) existing in the molybdenite in a slag layer. The exemplary embodiment can shorten a process as compared to a metallothermic reduction (Thermit) method of the related art and reduce the consumption of a reducing agent, i.e., aluminum.Type: GrantFiled: October 20, 2010Date of Patent: September 18, 2012Assignee: Korea Institute of Geoscience and Mineral Resources (KIGAM)Inventors: Young Yoon Choi, Sang Bae Kim, Chang Youl Suh, Chul Woo Nam
