摘要： A picture display device having a display tube and a deflection unit comprising a field deflection coil and a line deflection coil is disclosed. To comply with a predetermined interference radiation standard, the picture display device is provided with one interference suppression coil or with a system of interference suppression coils, which interference supression coil or system of interference suppression coils is oriented and can be energized in such a manner that, measured at a predetermined distance from the picture display device, the strength of the local magnetic dipole field is below a desired standard.

摘要： To improve the trichromatic cathode tube shielding effect given by the frame-mask set and by a shielding material made with material of low magnetic permeability, the external conductors of a de-magnetization coil with two loops are made to pass in front of the fastening lugs and not behind the frit plane as was the case before, and the position of the internal conductors is set to obtain the best compromise.
摘要翻译：为了改进由框架掩模组和由具有低磁导率的材料制成的屏蔽材料给出的三色阴极管屏蔽效应，使具有两个环的去磁线圈的外部导体通过紧固凸耳前面而不像之前那样在玻璃料平面后面，内部导体的位置设定得最好的妥协。

摘要： A degaussing coil holder according to the present invention comprises a retaining member provided with insertion holes formed in right and left positions adjacent to each other and further provided in the insertion holes with retaining pawls which are urged and project in directions opposite to each other, and band straps each provided at one end thereof with a degaussing coil holding portion, with the other ends being inserted through the insertion holes from openings of the holes positioned in opposite directions, and further provided on one side thereof with a series of ratchet serrations adapted to engage the associated retaining pawl in the insertion hole. Therefore, the unevenness is reduced and the volume efficiency is high. Moreover, the holding tension between degaussing coil portions can be adjusted over a wide range.
摘要翻译：根据本发明的消磁线圈架包括保持构件，该保持构件设置有彼此相邻的左右位置形成的插入孔，并且还在插入孔中设置有保持爪，该保持爪被推压并相对于彼此相反的方向突出，带状带，其一端各设置有消磁线圈保持部，另一端从位于相反方向的孔的开口穿过插入孔，并且在其一侧还设置有一系列棘轮锯齿，其适于将相关联的保持爪接合在插入孔中。因此，不均匀性降低，体积效率高。此外，可以在宽范围内调节消磁线圈部之间的保持张力。

摘要： A degaussing structure for a video tube which serves to demagnetize the tube and an apertured beam-selecting member in the tube. A shroud surrounds the forward portion of the tube and the apertured beam-selecting member. A pair of degaussing coils which are connected in series are wrapped around cutout areas in the shroud at the top and bottom thereof such that the magnetic flux produced by the current carrying coils is in a direction to degauss the apertured beam-selecting member.
