Title:
【発明の名称】陰極線管偏向ユニット及びその製造方法
Document Type and Number:
Japanese Patent JPH10508426
Kind Code:
A
Abstract:
The deflection unit has a yoke ring mounted on, and secured to, a coil assembly comprising deflection coils carried on a support. The yoke ring (22) is secured using a flow process in which the coil assembly is rotated about a vertical axis and flowable adhesive, e.g. polyurethane resin, is directed at one end (28) of the yoke ring such that the adhesive (30) flows over its outer surface (24) to its other end, forming a protective coating, and onto an adjacent part (20) of the coil assembly. The adhesive flows also over a substantial portion of the inner surface (23) of the yoke ring in the gap between the yoke ring and the coil assembly providing extensive bonding (32) between the yoke ring and the coil assembly which reduces unwanted noise effects from the unit in subsequent operation.
