Patent number: 5343111Abstract: A cathode ray tube having degaussing coils attached to an outer side of a glass vessel of a funnel part of a main body of the cathode ray tube, in which the degaussing coils each include a flattened part, extended along the outer front surface at a front side of a funnel part, a circular part having a circular cross-section and a transition part interconnecting the end parts of the flattened part and the circular part and changed in cross-section shape from a flattened rectangle to a circle. The degaussing coil may has shape flattened partially to reduce the outer size of the cathode ray tube and includes a plastic case for retaining the coil in the flattened shape. The degaussing coil is stabilized in shape and is not deformed during transport while its attachability with respect to the cathode ray tube may be improved.Type: GrantFiled: October 9, 1992Date of Patent: August 30, 1994Assignee: Sony CorporationInventors: Toru Miwa, Yasuyuki Yamasaki, Akihiko Yamagishi
