Power diodes based on single silicon crystals of cylindrical (tubular) shape
Babak A.G., Meshalkin N.I., Kozhitov A.V., Kondratenko T. T., Kurbatov A.V., Silaev I.V., Bliev A.P.The article provides a brief analysis of the advantages of power rectifier diodes made on the basis of single crystals of silicon in the form of thin-walled hollow cylinders (tubes). The values of the operating parameters of experimental samples of tube-shaped rectifier diodes for an operating voltage of 80 V and an operating current of 100A are given.
Problems of quality and reliability, certification, standardization
Problems of improving the quality of a generator set using discrete or polynomial models
Kozlovsky V.N., Evdokimov V.G.The paper analyzes modern methods of improving the quality and optimizing the processes of designing and manufacturing automotive generators. Increasing the stability of the technical characteristics of the generator, in the conditions of the existing technological process, can be achieved by introducing selective assembly. To implement this program, it is proposed to use a discrete or polynomial generator model, which organizes a rapid transition from the dimensional parameters of the assembly units of the generator core to its technical characteristics. This provides a system for predicting output characteristics at the production stage, which meets the modern requirements of the manufacturing process.
Tasks and functions of the enterprises of the second suppliers accredited in the Certification System "Voenelektronsert"
Stepanov Yu.I.It is known that in the conditions of market relations, the connection between manufacturers and consumers of products is most optimally provided by the institution of intermediaries, i.e. organizations that purchase products from manufacturers and sell them. A network of distributors performs these functions abroad. There are also distributors of national economic products in Russia, including electronic equipment.
