Patent number: 9404398Abstract: A continuously variable valve timing device is provided and includes a cam sprocket connected with a camshaft having a plurality of cams to rotate the camshaft and an electric variable valve timing mechanism connected with the cam sprocket, and driven by an electric motor. A chain cover protects the cam sprocket and a chain system from foreign substances and an electric variable valve timing mechanism cover protects the electric variable valve timing mechanism from foreign substances. A seal ring partitions an internal space between the electric variable valve timing mechanism and the electric variable valve timing mechanism cover. In addition, a pressure maintaining device is mounted within the electric variable valve timing mechanism cover to maintain pressure formed within the internal space of the electric variable valve timing mechanism cover at about atmospheric pressure.Type: GrantFiled: June 12, 2014Date of Patent: August 2, 2016Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Seung Woo Lee, Hyunjin Kang, Jae-Chun Kim, Hong Kil Baek, Gang Il Kim

Publication number: 20140017847Abstract: Provided is a method of manufacturing a solar cell, wherein a solar cell is manufactured by combining a damage removal etching process, a texturing process and an edge isolation process. The method is advantageous in that RIE and DRE are conducted, and then DRE/PSG and/or an edge isolation removal process are simultaneously conducted, so that the movement of a substrate (that is, a wafer) is minimized, thereby reducing the damage rate of the substrate.Type: ApplicationFiled: February 24, 2012Publication date: January 16, 2014Applicant: Hanwha Chemical CorporationInventors: Deoc Hwan Hyun, Jae Eock Cho, Dong Ho Lee, Gui Ryong Ahn, Hyun Cheol Ryu, Yong Hwa Lee, Gang Il Kim
