The complex of technological and metrological researches concerning development of filamentous monocrystals application and fixing methods on various materials of substrate (elastic elements) is considered. The ways of uncontrolled distortions avoiding of the initial monocrystal defect-free structure that can occur at the nodes of its mounting and reduce the Q-value of the resonator oscillations, which is the main characteristic of the tensotransducer quality, is shown.
Overviewed conceptual basis for development frequency dividers and disadvantages of standard decisions were analyzed. A high-speed with variable division ratio and minimum phase shift of output signal against input signal, which forms output square waves, is presented in the article.
Vibratory conveyor with three-component oscillations provides the opportunity to move the piece goods and details for any trajectory on a plane. Phase difference between independent horizontal (longitudinal or transverse) and vertical (normal) oscillations releases elliptical vibration of conveyor in plane perpendicular to the conveyor’s track. Elliptical vibrations allow increasing conveying velocity and inclination angle of conveyor’s track in comparison with the simplest linear vibrations.
Investigation of electromagnetic and electromechanical processes, which take place in the autonomous power supply system based on asynchronised generator with three phase modulated exciter, was conducted by means of mathematic experiment. The processes in terms of work suitableness of power supply system during its work at the junction of asynchronous motors and active-inductive load were analysed. Regularities of electromagnetic and electromechanical processes, depending on the schedule of consumers’ work and system of commutator management parameters were determined.
The description of law frequency vibrocavitator design for cavitational processing of chemically active liquids, liquids under pressure and high temperature is carried out. Its basic design and technological parameters are set up; by controlling them one can choose optimal regimes of cavitational processing. A special device for choosing range frequency fluctuation of cavitation breakers is developed.
The article is dedicated to one of the most important areas of quantitative studies of language and speech that is the study of information and statistical properties of text. An attempt was made to establish Cheremshyna’s literary works percentage sufficient to analyze relative frequencies of characters in his works and to investigate the stability of these frequencies. A number of conclusions were made about the size of text passages which may form text-sample for statistical surveys.
