Abstract: Изобретение относится к контрольно-измерительной технике, в частности к области методов контроля толщины покрытий в установках электронно-лучевого испарения. Способ непрерывного контроля толщины напыляемой на лопатки керамики заключается в определении толщины напыляемого покрытия по контрольному образцу, размещенному в одной камере с лопатками. Перед началом рабочего напыления экспериментальным путем при заданных скорости напыления и температуре лопаток определяют зависимость толщины напыленного на лопатки слоя от привеса на контрольном образце и строят градуировочный график. В течение всего цикла рабочего напыления непрерывно контролируют скорость напыления, температуру нагрева лопаток, а также привес на контрольном образце. Останавливают процесс напыления при достижении привеса на контрольном образце, соответствующем по заранее построенному градуировочному графику требуемой толщине напыленного слоя на лопатках. Изобретение позволяет повысить точность измерения толщины напыляемого слоя керамики на лопатках, а соответственно, повысить качество продукции, снизить количество лопаток с недопыленным или перепыленным слоем керамики, идущих на переподготовку и перенапыление. 2 з.п. ф-лы, 1 табл., 3 ил.

Granted: 1982-01-28
Abstract: In a time-division multiplexing system, data are supplied to the multiplexer with different speeds. Depending on the speed, time slot groups are allocated to the data, with the number of allocated time slots increasing with the speed. The search for groups of free time slots occurs in a fixed sequence. Data to which time slot groups at the end of the fixed sequence have been allocated, are relocated to time slot groups which have become free nearer the beginning of the sequence. The allocated time slot group for the forward transmission direction is signalled to the multiplexer of the remote station which in turn occasions a corresponding allocation of time slots for the reverse transmission direction for data originating at the remote station.
