Abstract: The method and the device are used in television studio engineering and ensure an invariably high quality of programme signal after symbols have been introduced into the latter. These can also be used in a studio which operates in accordance with the SECAM standard. The method consists of adding the programme signal and the symbol signal, the level of which is formed in such a manner that its value is always less than or equal to the difference between the brightness level of the symbol transmitted in the picture and the instantaneous brightness level of the programme signal. The brightness level of the symbol transmitted in the picture is constant (maximum or zero) or changes as a function of the instantaneous brightness level of the programme signal. The device is used in television studio engineering in all standard systems for colour transmission. Its application is particularly advantageous in SECAM signals because the mixing occurs without frequency division of the chrominance signal and without demodulating it. The adaptive method is used for forming the level of the graphic signal. The adaptivity compared with the signal is continued with reference to the optimum final contrast of the inserted graphics in accordance with the continuous brightness which also creates a novel effect of transparency in the inserted image. In the device, simple and consistent translators of the levels of the input video signal with final key processing are used, in which, apart from high consistency and accuracy, an increased signal/noise ratio is also achieved because the channel for the processing is closed when there is no signal for inverting. <IMAGE>

Abstract: A process for producing a reformed pitch useful for various carbon materials is provided. This process com­prises mixing a pitch having a ratio of aromatic hydrocar­bon fa of 0.6 or more with a Lewis acid and a co-solvent so as to give a mol ratio of the said Lewis acid to the said pitch in the range of 0.3 ∼ 5.0 and a mol ratio of the said co-solvent to the said pitch in the range of ratio of 2.5 ∼ 50, reacting the mixture at a temperature of 100 ∼ 300°C and removing the Lewis acid and the co-­solvent from the reaction product. Meso-Carbon microbeads having a uniform diameter of 20µm or less can be produced at a high yield of 60% or more by heat treating the reformed pitch at 200 ∼ 380°C to produce the optically anisotropic small spheres and separating them from an op­tically isotropic matrix.

Abstract: A facsimile apparatus (2) is connected to another (5) through a communication network (NW1) that may include a network of relative good transmission quality (e.g. a conventional wire network) (NW1A) and a network of relatively bad quality (e.g. a mobile 'phone network) (NW1B). If the selected transmission path is of good quality, transmission is carried out in a conventional manner. However, in the event that the transmission path is of relatively bad quality, an adaptive type error control means is utilised for error correction in response to the quality of the transmission path.
