Appraisal of chrome ores from several deposits

Chrome ore shipments from the Pobuzhskoe deposit (Ukraine), Turkey, and the United Arab Emirates (UAE) were appraised for chemical and mineral composition. Laboratory tests were made and trial lots of refractories were fabricated. The Turkish and UAE chrome ore and also Pobuzhskoe chrome ore with 39 to 45% Cr₂O₃ were found suitable for the manufacture of chrome refractory products.

Use of laser trimming for the development of a project for accuracy-normalization of the resistance of resistors in hybrid integrated circuits

The possibilities for laser trimming are studied, the disadvantages of this method are revealed, and the ways of developing this approach on the basis of computer-aided design and modeling are proposed. The hierarchy analysis method and the fuzzy-set theory are used to evaluate the normalization projects.
