Patent number: 9568728Abstract: An electrowetting display device includes a first substrate comprising a wall pattern surrounding a pixel electrode disposed in a display area of the first substrate, a spaced apart second substrate comprising a common electrode and a dam member disposed in a peripheral area surrounding the display area. The dam member has sealable openings (a.k.a. sealable dam spillways) through which there is discharged an excess portion of an excessively supplied wetting layer, the discharge of the excess occurring while the first and second substrates are brought together about top and bottom portions of a sealing ring that seals them together.Type: GrantFiled: August 11, 2016Date of Patent: February 14, 2017Assignee: Samsung Display Co., Ltd.Inventors: Dong-Hwan Kim, Sung-Ku Baek, Gil-Hwan Yeo, Tae-Woon Cha, Gyung-Mo Tahk

Publication number: 20140091067Abstract: A device that prevents soot in a stud welding machine. In particular, the device includes a cap holder that is fitted on a stud chuck of a stud gun for a stud welding machine and has extenders at the sides thereof. In addition, fixing rods attach the cap holder to the stud gun by connecting the extenders of the cap holder with the sides of the stud gun and a cap that is inserted in the cap holder from below is movably combined with the cap holder by a cap nut, and has an end that comes in contact with an edge of a welding portion of a base material during stud welding. Further, a shock-absorbing member is disposed between the cap and the cap holder, inside the cap holder, and provides an elastic force to the cap.Type: ApplicationFiled: September 30, 2013Publication date: April 3, 2014Applicants: SUNGWOO HITECH CO., LTD., HYUNDAI MOTOR COMPANYInventors: Han Jaehee, Sung Ku Baek

Patent number: 7792453Abstract: An image forming apparatus capable of minimizing a temperature rise of a cover by substantially preventing heat emission from a fusing device to an outside is disclosed. The image forming apparatus includes a main body, a fusing device mounted in the main body, the fusing device having an outlet to discharge paper, an opening/closing member opening and closing the outlet of the fusing device, a cam member moving the opening/closing member between a first position in which the opening/closing member closes the outlet to prevent heat in the fusing device from being emitted through the outlet and a second position in which the opening/closing member opens the outlet to permit the paper to pass through the outlet, a driving part rotating the cam member, and a control unit controlling the driving part to determine a rotational position of the cam member.Type: GrantFiled: May 15, 2008Date of Patent: September 7, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Sung Ku Baek, Sung Hyup Kim, Sun Soo Kim, Gyu Deok Hwang, Jong Woo Kim, Hyun Ki Cho, Je Hyoung Ryu, Tae Hee Kim
