Publication number: 20150044665Abstract: The present invention relates to a target-specific probe containing T7 bacteriophage with a targeting antibody, and a detection method or a detection kit for a biomarker using the target-specific probe. The biomarker can be detected by using the genetically-modified T7 bacteriophage expressing various heterogeneous proteins and peptides on its surface and antibody-antigen specific reaction which can make the probe targeted to a biomarker or bacteria; and a detectable labeling agent, for example a quantum dot.Type: ApplicationFiled: October 23, 2013Publication date: February 12, 2015Applicant: KOREA INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Kwan-Hyi LEE, Jong-Hoon CHOI, Jong-Wook LEE, Hyun-Kwang SEOK, Mintai Peter HWANG, Jang-won SONG

Patent number: 7038367Abstract: An electron gun for a cathode ray tube includes a triode portion including cathodes, a first electrode, and a second electrode arranged with predetermined gaps therebetween. A plurality of electrodes arranged in sequence starting from a position adjacent to the second electrode. The electrodes receiving a voltage, for example, a constant voltage or a dynamic voltage. The dynamic voltage is synchronized with a deflection signal of electron beams. An anode electrode is positioned having a predetermined gap between the electrode arranged farthest from the cathodes. A support maintains the electrodes at predetermined intervals. One of the electrodes is a multiple-element electrode that includes two interconnected sub-electrodes. Gaps are formed between portions the sub-electrodes of the multiple-element electrode.Type: GrantFiled: July 30, 2003Date of Patent: May 2, 2006Assignee: Samsung SDI Co., Ltd.Inventors: Jong-Hoon Choi, Min-Cheol Bae

Publication number: 20020132526Abstract: A base cap for a cathode ray tube (CRT) preventing insulation breakdown between a lead pin to which a high voltage is applied and a lead pin to which a comparatively low voltage is applied. Insulation breakdown due to poor application of a silicone composition between a stem of the CRT and a flange of the base cap is avoided. The base cap includes a cylindrical housing, a flange extending radially outward from the edge of the cylindrical housing and including holes into which lead pins fixed to the stem of an electron gun of the CRT are inserted; and at least one isolation element on the surface of the flange, facing the stem, for preventing breakdown of insulation between the lead pins.Type: ApplicationFiled: December 28, 2001Publication date: September 19, 2002Applicant: Samsung SDI Co., Ltd.Inventors: Min-Cheol Bae, Jong-Hoon Choi, Woo-Seok Huh
