Publication number: 20200274195Abstract: In order to improve the safety of a rechargeable battery, methods for manufacturing the rechargeable battery using a solid-state electrolyte are being studied. However, a process of manufacturing the all-solid state rechargeable battery by separately preparing and laminating an electrode and a solid-state electrolyte is not only complicated, but also may cause side reactions due to residual moisture between the electrode and the solid-state electrolyte. In addition, additional processes are required to reduce the interface resistance between the electrode and the solid-state electrolyte. In order to solve these disadvantages, the present invention is to manufacture an integral all-solid state rechargeable battery by applying a mixed slurry of a conductive ceramic material and a polymer mixed with a solvent onto an electrode, evaporating the solvent, absorbing a liquid electrolyte, and then covering the electrode with a counter electrode.Type: ApplicationFiled: September 27, 2018Publication date: August 27, 2020Applicant: SEVEN KING ENERGY CO., LTD.Inventors: Jung Woo Son, Ji Won Son, Hyun Ji Choi, Jae Kwang Kim

Publication number: 20140233974Abstract: A method and apparatus for forming an image determine if printing paper is properly picked up, and printing data is transferred to an intermediate transfer belt (ITB). When it is sensed that the printing paper is not properly picked up, picking up the printing paper is retried considering a revolution cycle of the ITB. Thus, the frequency of errors can be decreased, and a user's convenience can be increased because picking up the printing paper is automatically retried whenever mis-pick up occurs instead of displaying an error. Further, wasting of toner is decreased.Type: ApplicationFiled: April 4, 2014Publication date: August 21, 2014Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jung-woo SON, Cheol-ju Yang

Patent number: 8010003Abstract: When the density of a toner image of a leading end of a printing sheet is no less than a predetermined reference density, a printing start time is delayed or printing data is deleted so that printing data is not printed in the leading end of the sheet. When the printing is performed in a state where a cover used for copying is opened, a printing start time is delayed or the printing data of the leading end of the printing sheet is deleted. Therefore, it is possible to prevent a fixing unit from being contaminated due to the toner image transferred to the leading end of the printing sheet.Type: GrantFiled: September 13, 2007Date of Patent: August 30, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Jung Woo Son, Soo Cheol Park

Patent number: 7720422Abstract: A fuser cleaning apparatus and method of operating a fuser cleaning apparatus for use with an image forming device. Heat is efficiently transferred to a guide member of a fuser, thereby allowing for relatively easy performance of a cleaning operation of the fuser, since a heating roller of the fuser is heated by a heater while the heating roller is not in motion. It is also possible to prevent melted toner remnants from contaminating the heating roller since a sheet of paper which has waited at an entrance of the fuser is conveyed and passed between the heating and pressure rollers of the fuser after the heating roller is heated while it is not in motion.Type: GrantFiled: September 21, 2007Date of Patent: May 18, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Jung Woo Son, Soo Cheol Park
