Abstract: Изобретение относится к химико-фотографическим материалам, используемым для получения фотоформ - фотошаблонов с помощью лазерных гравировальных автоматов. Материал представляет собой полиэтилентерефталатную основу (ПЭТ-основу), на которую нанесен чувствительный к лазерному излучению слой - приемный слой. Приемный слой получают нанесением на ПЭТ-основу композиции на органических растворителях и ее последующим высушиванием. Качество гравирования приемного слоя и, следовательно, качество получаемых фотоформ в большей степени зависят от величины адгезии приемного слоя к ПЭТ-основе. Задачей является увеличение адгезии приемного слоя к ПЭТ-основе. Поставленная задача достигается подслоированием ПЭТ-основы композицией на органических растворителях, в которой в качестве полимерного компонента используют насыщенные полиэфирные смолы, представляющие собой олигомерные сложные эфиры фталевых кислот и полиспиртов - этиленгликоля, или глицерина, или пентаэритрита, или их смесь, а одним из органических растворителей является N-метилпирролидон. 1 табл.

Abstract: FIELD: engines and pumps, electrical engineering. 
     SUBSTANCE: method is designed to convert electrical signal into a jet signal in automatic control systems with higher requirements to operating speed and noise immunity. The method consists in that the flow-through combustion chamber, directly before the jet element control channel, accommodates two electrodes arranged with a gap allowing a spark discharge at appropriate voltage at the electrodes. Gases, which, when mixed, form a blasting gelatine, are fed into the said chamber via separate channels at a pressure insufficient for the jet element operation. The said mixture is ignited by sending an electrical signal to the electrodes to form the detonation products that, getting expanded, increase the pressure in the combustion chamber to switch over the discrete jet element via the control channel. 
     EFFECT: shorter process of conversion, meeting the requirements to noise immunity.
