Patent number: 6462466Abstract: In a color cathode ray tube, inner lead pin segments which extend inside the neck of a funnel constituting an vacuum envelope, outer lead pin segments which are led out of the neck and interconnecting wires which respectively connect both lead pin segments together are provided in a stem for sealing the end portion of the neck. The inner lead pin segments are arranged along a first circumference and are supported by respective projections protruding from the stem. The outer lead pin segments are arranged along a second circumference having a larger diameter than that of the first circumference. The inner lead pin segments are connected to the respective outer lead pin segments by the respective interconnecting wires which are bent in the stem and the respective projections.Type: GrantFiled: October 12, 1999Date of Patent: October 8, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Shigeru Sugawara, Hiroyuki Koba, Fumitaka Hoshino, Hidenori Takata, Masatoshi Ichikawa

Patent number: 6455999Abstract: In a color cathode ray tube, the outer diameter of a neck is set at 22 mm-23 mm, the diameter of a pin circle formed by stem pins outside the flare section of a stem welded to an end of the neck is set at a nominal value of 15.24 mm, and the maximum diameter of a base adhered to an outer surface of the stem is set at 23 mm or less. Accordingly, while the neck outer diameter is reduced to reduce the power consumption of the color cathode ray tube, the color cathode ray tube has a high resolution.Type: GrantFiled: April 4, 2000Date of Patent: September 24, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Takahiro Hasegawa, Syunji Ookubo, Shigeru Sugawara

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

Patent number: 5990610Abstract: This invention secures the breakdown voltage between stem pins or the like for high voltage service in a cathode ray tube. This insulator is formed of a clay-like silicone compound having a tip-throughhole and pin-throughholes or a stem base with the electric insulator mounted to the stem base. An inter-stem electric insulation device is structured by mounting either one of the electric insulator or the stem base with the electric insulator to the stem of a cathode ray tube and by pressing to fix together. This structure does not allow bubble generation caused by the electric insulator, and makes the handling easy, and furthermore, allows an automatic mounting of the electric insulator to a stem.Type: GrantFiled: September 12, 1994Date of Patent: November 23, 1999Assignee: Sony CorporationInventors: Shigeo Matsumoto, Takashi Setsuda, Haruo Ito, Kazuyuki Ota

Patent number: 5246386Abstract: A structure for a terminal plug includes a thermoplastic resin base having a key boss and a plurality of protruding shafts formed integrally on a front side thereof. Terminal pins are formed on the plurality of protruding shafts by a chemical plating process. Connection patterns are disposed on the front side of the thermoplastic resin base and connected to said terminal pins, and circuit patterns are disposed on the back side of the thermoplastic resin base. A plurality of through-holes are formed in the thermoplastic resin base which electrically connect the connection patterns and the circuit patterns.Type: GrantFiled: March 25, 1992Date of Patent: September 21, 1993Assignee: Omron CorporationInventor: Hideo Nanjo

Patent number: 4868452Abstract: The electric lamp has a lamp vessel (1) having a pinched seal (2) in which a metal foil (3) is accommodated as current lead-through conductor, which is connected to several external current conductors (7). The current conductors (7) are secured via a metal strip (8) to a current supply wire (14). Thus, deformations of the external current conductors (7) are avoided, which lead to mechanical stresses in the pinched seal (2) and to rupture thereof.Type: GrantFiled: May 9, 1988Date of Patent: September 19, 1989Assignee: U.S. Philips CorporationInventor: Leo F.

Patent number: 4674821Abstract: A base for a CRT has an outside diameter which is less than the outside diameter of the tube neck. A plurality of resilient detents are integral with the base and act against the exhaust tubulation to help retain the base on the neck of the tube. A silo is integral with the base and surrounds the high voltage pin. The pins freely pass through pinslots to avoid bending the pins when putting the base onto the neck. The pinslots are configured to facilitate the reception of bent or misaligned pins.Type: GrantFiled: February 28, 1986Date of Patent: June 23, 1987Assignee: RCA CorporationInventor: Myron H.
