摘要： PURPOSE:To quicken the attenuation of the charge arising at the outside surface of a face plate by earthing the conductive film formed at the outside surface of the face plate to an explosion-proof band by the conductive member formed at the margin of this. CONSTITUTION:A band-shaped conductive material 10 is formed continuously around an irregular conductive film 2, according to the curvature of an R part, from the center R line of the R part being the coupling part between the face plate and the skirt part of a cathode ray tube 1 to the skirt part, and is connected at two or more places of connections on one side, to a metallic explosion- proof band 3 the connection 101. For the one constituted in this way, the film 2 and the band is connected enough by a member 10. The charge, which is generated on the outer surface of the face plate at on-off time of the power source of a cathode ray tube 1, attenuates quickly. Hereby, the adhesion of minute dust in the air can be prevented from adhering to the outer surface of the face place and also discomfort from arising in a supervisor by discharge phenomena.

摘要： PURPOSE: To accurately position a loop by providing each device with at least one hook including a supporting part for each loop fitting point and capable of fitting freely turnably the supporting part. CONSTITUTION: The device 1 for fitting the demagnetization loop is fitted to the head part of a screw 3 and the members of the device 1 are molded from a plastic material. A wire 1A is blocked between lingulate parts 18, 19 and lods 16, 17 so as not to be moved. Since hooks 18, 19 are arranged symmetrically about a blacket 10 and a base 9 and the blacket 10 has slight elasticity, the device 1 can be rotated around the axis of the screw 3. Since four deices 1 are arranged in the hexagon head direction of a cover, the demagnetization loop can be positioned in a sufficiently tense state only by inserting the loop into the inside of the four devices 1.

摘要： PURPOSE: To generate a magnetic field at a desired location and cancel parasitic magnetic field effect for a charged particle by depositing a conductor on a support so that the absorbance of the electromagnetic wave of a specific frequency band is constant over nearly the entire surface of a coil. CONSTITUTION: A coil 2 has a support 3 that is constituted of a plate where two main surfaces are separated by nearly equal distance over the entire surface of the coil. A conductive track 1 with a first pattern 12 is deposited on the first surface of the support 3. A pattern 13 that is constituted of a conductive track 10 is deposited on the second surface of the support 3 of the coil 2. The track 10 of the pattern 13 is complementary to the track 1 of the pattern 12. The track 1 and the track 10 are connected mutually at least at one point that crosses a connection part 11 provided at the support 3. The mutual connection part 11 is located at the center of, for example, the circular coil 2. A magnetic field generated by the track 1 of the pattern 12 needs to be added to a magnetic field generated by the track 10 of the pattern 13 and, for example, the patterns 12 and 13 are formed by a concentric arc and/or a square spiral.

摘要： PURPOSE:To provide possibility of fitting easily without damaging the base of a cathode-ray tube by chamfering the open end of a neck pipe guide pact and the socket part. CONSTITUTION:Chamfers 13, 14 are furnished at the open end of a neck pipe guide part 10 and the socket part 8. One to this chamfer 14 the neck 9 of a cathode-ray tube can be easily inserted in the neck pipe guide part 10 even though the base 3 of the cathode-ray tube 1 has a deviation of locational accuracy to a certain degree, to allow automatic location in high precision. followed by accurate and smooth insertion into the socket part 8 owing to the chamfer 13 on it. Eccentricity of the socket part 8 from the base 3 generated when the base 3 is inserted into the socket part 8 is absorbed by a damping part 11, which is well made even though there is tolerance in the overall length from the face plate of the cathode-ray tube to the base tip. Thus socket insertion can be made smoothly without causing damage to the base 3.

摘要： PURPOSE:To provide applicability of a cathode-ray tube of one sort to a plural ity of purposes with significantly different deflecting magnetic field frequencies by constructing the electron tube so that its different parts are located substan tially outside the magnetic field of the deflection yoke. CONSTITUTION:An electron gun 3 is constructed so that its different parts are located substantially outside the magnetic field of a deflection yoke 2. This eliminates necessity for resorting to a special measure for avoidance of ill influence of the deflecting magnetic field through assumption of a deflecting mag. field with a certain frequency on the electron gun 3 side in terms of design. That is, it resolves all such problems likely to occur on a color tube as variation in the concentrated condition of three electron beams, which might influence seriously the color pureness, and local overheating of a shield cup to be generat ed when the frequency of the deflecting mag. field is very high.
