Patent number: 11123703Abstract: Apparatus for producing fine particles having a particle formation mechanism and a particle-outlet micro-channel may include a unit-structure including first and second portions adjacent to each other; and a first inlet defined in the first portion at a first height. A continuous phase solution is injected into the first inlet; and a second inlet is defined in the first portion at a second height different from the second height. A dispersed phase solution is injected into the second inlet. A merging volume is defined in the second portion and is defined at third height equal to either the first height and the second height, or has a value therebetween. The continuous phase solution and the dispersed phase solution are merged in the merging volume, wherein fine particles are formed. A first micro-channel and a second micro-channel branching from the merging volume communicates with the first inlet and the second inlet, respectively.Type: GrantFiled: March 22, 2017Date of Patent: September 21, 2021Assignee: ENPARTICLE CO.,LTD.Inventors: Jeung Sang Go, Hyo Chang Cho, Hyeong Jin Jeon, Moon Jeong Kim

Patent number: 10066923Abstract: An ice thickness measurement sensor 100 is provided to measure the thickness of ice extending from a circuit. The ice thickness measurement sensor comprises at least one capacitive sensor 150. The capacitance of the sensor 150 depends on the thickness of ice covering the sensor, because the presence of the ice changes the permittivity. The ice thickness measurement sensor may be used in a fluid pipe, for example to measure the thickness of ice extending from the inner surface of the pipe.Type: GrantFiled: February 19, 2015Date of Patent: September 4, 2018Assignee: ROLLS-ROYCE plcInventors: Jeung Sang Go, Man Yeong Ha, Changmin Son, June Kee Min

Publication number: 20100166964Abstract: The present invention relates to a method for attaching a micro bubble array on a plate surface, and more particularly, to a method for attaching micro-sized bubbles on a plate surface so as to reduce fluid frictional resistance caused by flow on the plate surface that encounters with liquid. The method for attaching a micro bubble array on a plate surface according to one aspect of the present invention includes a micro groove forming step and a hydrophobic treatment step. In the micro groove forming step, a plurality of grooves with a size of 1 to 1,000 micrometers are formed in a plate surface to be arranged therein. In the hydrophobic treatment step, the plate surface having the grooves formed therein is coated with a material having a hydrophobic property. Since the plate surface has the plurality of grooves arranged therein and also is treated with a hydrophobic material, micro bubbles are formed on the micro grooves when the plate surface goes under water.Type: ApplicationFiled: September 18, 2009Publication date: July 1, 2010Inventors: Jeung Sang Go, Moon Jeong Kim, Bong Hyun Kwon
