Improvement of technological process of galvanizing in flowing electrolyte without decrease in its reliability and quality of the received deposit can be carried out by carrying out anode etching of the processed surface directly in the main electrolyte of sedimentation. And, providing such conditions of anode etching at which, the details which are formed on a surface products of reactions easily are removed a channel of electrolyte is possible. For the purpose of identification of extent of influence of technology factors on anode dissolution of the processed surface it is necessary to conduct elektrokhikmichesky researches. The installation including electric was for this purpose developed and made and gidravklichesky speak rapidly. The Elektkrichesky part contains power-supply circuits of an electrolytic cell to the asymmetric variables odnopoluperiodno straightened, dvukhkpoluperiodno straightened by current and straightened by current with the lowered pulsation, and also a chain of heating of working electrolyte. The hydraulic scheme of experimental installation includes: the kisloktostoyky electric pump, pipelines, filters, the device for an electrolytic precipitation of coverings and a bathtub with electrolyte. Electrolyte in a cell moved by means of the electric pump. Giving changed in steps, due to change of diameter of the section through passage of the giving pipeline by means of replaceable inserts. Authors of the device for electrolytic drawing coverings are Zakharov Yu.A. and Spitsyn I.A. (patent No. 2155827). The design allows: to increase the speed of a channel of electrolyte; to carry out activation of the cathode, using energy of a channel of electrolyte; to increase the accuracy of copying of the cathode the activating elements; to use higher density of current and to reduce power consumption of the device. Electrolyte, in the course of sedimentation, was constantly filtered. As filtering material used fiber glass. The filter if necessary it is possible to dismantle and wash out quickly. Such filtering element slightly interferes with a channel of electrolyte, is simple in service, is cheap and quite sufficient. Thus, the offered design of experimental installation allows to conduct necessary researches of process of sedimentation of a zinc electrodeposit for its improvement.

Nowadays, the main way to improve power density is increasing the junction temperature of semiconductor devices and as a result, increasing the temperature of the heat sink. This results in a lower efficiency due to the high temperature caused by increasing power losses. To solve this problem, it’s possible to develop the heat sink for a specific system, or to optimize existing heat sink profiles. This paper presents an FEM-analysis describing thermal behavior of a bidirectional switch used in a direct matrix converter.

The basic virtue of the sowing apparatus of an overpressure is possibility of conducting of sowing on the big speeds and with high uniformity of dispensing of seeds. But the processes occurring in the sowing apparatus of an overpressure at dispensing of seeds, are insufficiently studied. In the article one of stages of process of dispensing by the overpressure sowing apparatus - transportation of a unit seed by dosing elements of a seed disc is observed. The forces acting on a seed in the course of transportation with a dosing element of a seed disc are defined. The gravity, centrifugal force, force of air drag and pressure force of air refers to to them. The scheme of forces is presented. As a consequence of theoretical research dependence of magnitude of an overpressure in the seed vessel from key parameters of work of the sowing apparatus of an overpressure has been defined. Graphs of theoretical dependence of pressure in the seed vessel from diameter of holes and a seed disc angle of rotation are built. The analysis of the gained results allows to draw following conclusions. The increase in diameter of holes of dosing elements of a seed disc leads to considerable decrease of the pressure necessary for transportation of a seed. At increase in an angular velocity of a seed disc pressure necessary for the secured transportation of a seed is augmented. The increase in an angle of rotation of a seed disc puts insignificant agency on pressure in the apparatus seed vessel.
