Abstract: FIELD: communication equipment. SUBSTANCE: device has communication channel cells, each of which has base station, which process joint control channel for calling mobile station and access channels for connecting mobile station or establishing call from it. Mobile station has information about frequency range of all access channels. Connections are established using duplex communication channels. Physical region which is covered by all respective communication channel cells is detected by means of tools for servicing all communication channels within this region for defined common targets. Each communication channel cell has at least two access channels which frequencies are separated by given level and provide same effective range as communication channels. When mobile station needs access, it scans signal level or power for all access channels twice in moments which are separated by 20 ms. Duplex access channels provides possibility to find access channel with maximal signal level in spite of heavy fading. Mobile station in this case establishes communication using communication channel in most pertinent cell with maximal signal level. EFFECT: decreased occurrences of communication channel switching, improved quality of voice signal, increased speed of establishing connection. 2 cl, 11 dwg

Abstract: FIELD: plasma engineering; coating large-area sheets of insulating materials. SUBSTANCE: unit comparing mean values of power and rate of current and voltage variation with reference signals is introduced in power system of magnetron phytosystem. Its output is connected to current interrupter and, through delay line, to starting device of adjustable regulated- voltage supply. When using phytosystem with small working chamber for coating large-area sheets, it will be good practice to make output sluice chamber in the form of blind pocket. For multiple-cathode phytosystems with long working chamber, multichannel gas admission system is used to pass gas through injection holes spaced maximum 100 cm apart. When such working chamber is divided by diaphragms into separate compartments and injection holes in each compartment are connected to separate gas admission system, such arrangement can apply multilayer coats simultaneously. Ionic cleaning functions are implemented by means of electrodes installed in sluice camber and connected to additional high-voltage supply. The latter may be of pulse type. EFFECT: provision for avoiding transfer of glow discharge into arc discharge thereby preventing failure of facility and coatings. 6 cl, 4 dwg

Abstract: Изобретение относится к буровой технике, а именно к средствам контроля забойных параметров при бурении и геофизических исследованиях скважин. Задачей изобретения является повышение достоверности приема информационных сигналов при весьма малой мощности излучателя. Это достигается тем, что передача электрических сигналов, возникших в результате создания электрического потенциала между массой колонны бурильных труб и излучающим электродом, установленным в промывочной жидкости внизу колонны бурильных труб, происходит по промывочной жидкости и токопроводящему металлу колонны бурильных труб, электрически разделенных между собой оксидным слоем. В данном случае используется эффект, возникающий от разной электропроводности металла труб буровой колонны, промывочной жидкости и поверхностного слоя буровых труб, образованного оксидной пленкой. Электрические сигналы передаются по металлу трубы и промывочной жидкости, разделенным поверхностным слоем, имеющим существенно меньшую электропроводность, чем металл и промывочная жидкость. Прием электрического сигнала осуществляется приемным устройством, установленным на устье скважины, приемный электрод которого размещен в промывочной жидкости, и по току между приемным электродом и колонной бурильных труб судят о параметрах бурения. 1 ил.
