(54) ПРИЕМНАЯ ЭЛЕКТРОННОЛУЧЕВАЯ ТРУБКА ДЛЯ ЦВЕТНОГО ТЕЛЕВИДЕНИЯ(54) RECEPTION ELECTRON BEAM FOR COLOR TELEVISION

1one

Изобретение относитс  к области цветного телевидени , в частности, к усовершенствованию цветных электроннолучевых трубок масочного типа.The invention relates to the field of color television, in particular, to the improvement of color electron-beam tubes of the mask type.

Известна приемна  электроннолучева  трубка дл  цветного телевидени , в которой цветоделительным элементом  вл етс  апертурна  маска одинаковой толщины по всей ее поверхности.A prior art receiving tube for color television, in which the color separation element is an aperture mask of uniform thickness over its entire surface, is known.

Недостаток этой трубки заключаетс  в том, что за счет неравномерного нагрева поверхности маски при ее бомбардировке электронным пучком ухудшаетс  качество воспроизводимого изображени . Это объ сн етс  разной теплопроводностью рабочей поверхности маски И поверхности, не имеющей отверстий.The disadvantage of this tube is that due to the uneven heating of the surface of the mask when it is bombarded by an electron beam, the quality of the reproduced image deteriorates. This is due to the different thermal conductivities of the working surface of the mask AND the surface that does not have holes.

Цель изобретени  - улучщение распределени  температуры по всему объему маски во врем  бомбардировки ее электронными пучками И предотвращепие механической деформации отверстий в маске.The purpose of the invention is to improve the temperature distribution throughout the volume of the mask during electron beam bombardment and to prevent mechanical deformation of the holes in the mask.

Поставленна  цель достигаетс  тем, что нерабоча  поверхность имеет множество углублений . Толщина и форма углублений должна быть такой, чтобы масса на единицу площади поверхности была бы одинаковой па обеих част х поверхности маски (рабочей и нерабочей ).The goal is achieved by the fact that the non-working surface has many recesses. The thickness and shape of the recesses should be such that the mass per unit surface area is the same on both parts of the mask surface (working and non-working).

Благодар  этому улучшаетс  распределение температуры по всей поверхности маски, а соответственно улучшаетс  качество воспроизводимого цветного изображени .This improves the temperature distribution over the entire surface of the mask, and the quality of the reproduced color image accordingly improves.
