Description
Изобретение относитс к области фототелеграфной техники.The invention relates to the field of photo-telegraph technology.
Одним из недостатков фототелеграфной С1 стемы, работающей по методу однострочной развертки с. использованием проекционных электронно-лучевых трубок, вл етс песовершенетво их экранов, призод пдее к недостаточной ркости свечени п тна на фотобумаге. В описы ;аемом изобретении этот недостаток устранен посредством примече; (и в системе дополнительной цнлинд )1 ческой оитики 1 электронполхчевой трубки с п тном штриховой формы.One of the drawbacks of the phototelegraphic C1 system operating on the single-line scanning method using projection cathode-ray tubes, it is the advantage of their screens, the pride more to the lack of luminance of the spot on the photo paper. In the description of the invention, this disadvantage is eliminated by a note; (and in the system an additional cluster) of 1 C Oiti of an electron-microwave tube with a dashed spot.
Использование такой электроннолучевой трубки позвол ет увеличить ркость светового п тна на фотобумаге и этим дает возможность примен ть в фототелеграфировгтпп фотобумагу с меньшей чувствительHOCTbKJ .The use of such a cathode ray tube makes it possible to increase the brightness of the light spot on photographic paper, and this makes it possible to use photo paper with a smaller sensitivity OFCTbKJ in phototelegraphic technology.
На чертеже показан обпиш вит электронно-лучевой трубки 1 с п тно--: 1итр1 хоиой формы. даюпщм след от развертываюшего штриха 2. Лампа снабже ;а упраЕзл ющим электродол J, катодол 4, фокусирх-юп-ей катушкой -Т, диафрагмо 6 истрочю отклон ющей системой 7.The drawing shows the alignment of a cathode-ray tube 1 with the spot--: 1tr1 of its shape. give a trace of the developmental stroke 2. The lamp is supplied; and the control electrode J, the cathode 4, the focus-Yup coil —T, the diaphragm 6 using a deflection system 7.
однострочной разверткой по методу бегуптего луча путс применени дополнительно ц 1линдрпческой оптики , о т л i ч а О ш. 1 и с тем, что, с целью упрощени аппаратуры i ркости светового п тна, пр1 мен ютс. развертызаюище элекТрОП;;0-ЛучеВЬ е трубки с single-line scan using the beam-beam method of using an additional ti cylinder, optics, as follows: 1 and with the fact that, in order to simplify the apparatus i, the brightness of the light spot is changed. unwrap electropower ;; 0-ray tube with
