摘要： A stretched mask for a color picture tube and a material for the stretched mask. The stretched mask is formed from a nickel-iron alloy steel sheet made of a nickel-iron alloy containing 35.0% to 37.0% by weight of nickel and 0.01% to 0.06% by weight of carbon. The nickel-iron alloy steel sheet is provided with apertures by etching using a pattern provided on the sheet. The stretched mask is free from image degradation due to a rise in temperature.

摘要： An aperture grill for a cathode ray tube is formed with parallel slits by etching a cold-rolled low-carbon steel plate from the opposite sides thereof. Before carrying out the etching, the steel plate is subjected to an annealing step whereby the residual stress is reduced to 7.0 Kg/mm.sup.2 or less. The steel plate is also subjected to a tensile force for imparting a tension in the direction of the rolling of a hoop steel from which the steel plate is produced. Furthermore, the steel plate is so oriented that the direction of tapes of the aperture grill to be produced will coincide with the rolling direction. The above process makes it possible to prevent occurrence of "streaks" and improves the quality of images generated on the cathode ray tube.
摘要翻译：用于阴极射线管的孔格栅通过从其相对侧蚀刻冷轧低碳钢板而形成有平行狭缝。在进行蚀刻之前，对钢板进行退火工序，残留应力降低到7.0Kg / mm 2以下。钢板也受到张力的作用，该拉力用于在制造钢板的环形钢的轧制方向上施加张力。此外，钢板的取向使得要生产的孔格栅的带的方向与轧制方向一致。上述过程使得可以防止“条纹”的发生并且提高在阴极射线管上产生的图像的质量。

摘要： A slot tension-type shadow mask for the cathode-ray tube (CRT) has slots. Each slot has two openings and a pseudo-bridge between the two opening of the slot. The slots are formed in the X-Y plane that is formed away from the electron gun in the Z-axis. Each pseudo bridge has a pair of protuberances separated by a lacuna. The edges of each protuberance is etched to have various surface profiles in the X, Y, Z directions and/or the shape of the lacuna is also varied to provide effective shielding while overcoming various problems associated with heating and image imperfections appearing on the CRT screen.

摘要： A shadow mask is formed from a plate member comprising an outer frame portion, a body portion of a shadow mask having an outer peripheral line formed through an etching process and a plurality of connection portions through which the body portion of the shadow mask is supported by the outer frame portion. The shadow mask is formed from the plate member by removing the outer frame portion from the body portion of the shadow mask. In this process, a break portion is formed to the shadow mask by removing the outer frame portion so as to be recessed inward from the outer peripheral line of the shadow mask.

摘要： A method of producing an aperture grill of a CRT display device is disclosed. The aperture grill is of a small thickness of the order of 20 to 100 .mu.m. To a metal plate with front and rear surface resin layers are applied front slit pattern mask with a single broad slit pattern and a rear slit pattern mask with two adjacent, narrow slit patterns. With these two masks disposed in opposition, the slit patterns are printed and developed on the resist layers. Thereafter, etching is carried out on the rear surface of the metal plate via the rear resist layer, and rear cavities are formed in the metal plate. Then, a reinforcing, etchant-proof film is attached to the rear resist layer to cover the rear cavities, and thereafter etching is carried out on the front surface of the metal plate via the front resist layer, to thereby form a front cavity. As the front etching proceeds, the front cavity is caused to communicate with the rear cavities with the etchant flowing into the rear cavities, and the front and rear cavities are made into a single through slit. Thereafter the reinforcing film is removed. The method makes it possible to easily produce slits of dimensional accuracy.
摘要翻译：公开了一种制造CRT显示装置的孔格栅的方法。孔格栅的厚度小于20〜100μm。对具有前表面和后表面树脂层的金属板施加具有单个宽狭缝图案的前狭缝图案掩模和具有两个相邻的窄狭缝图案的后狭缝图案掩模。通过将这两个掩模相对设置，将狭缝图案印刷并显影在抗蚀剂层上。此后，经由后抗蚀剂层在金属板的后表面上进行蚀刻，并且在金属板中形成后腔。然后，将加强的耐蚀刻膜附着到后抗蚀剂层以覆盖后腔，然后经由前抗蚀剂层在金属板的前表面上进行蚀刻，从而形成前腔。当前蚀刻进行时，使前腔与后空腔连通，蚀刻剂流入后空腔，并使前腔和后空腔制成单个通孔。之后，除去增强膜。该方法可以容易地产生尺寸精度的狭缝。
