The reactive stresses induced in Ni₄₉Fe₁₈Ga₂₇Co₆-alloy single crystals during martensitic transformations with a limited possibility of shape-memory-strain recovery have been experimentally studied. The data on these crystals are compared with the results obtained previously for Cu–Al–Ni, Ni–Ti, and Ni?Fe–Ga crystals. The potential of application of the Ni₄₉Fe₁₈Ga₂₇Co₆ single crystals in designing drives and power motors is demonstrated.

Follow-up angle-to-digital converter with self-adjusting two-phase angle sensor

We consider a slave angle-to-digital amplitude converter structure in which the initial conversion accuracy that decreases with use is adjusted automatically.Translated from Izmeritelnaya Tekhnika, No. 11, pp. 25–27, November, 2004.     

Determining the Errors of an Angle Digitizer Containing a Two-Phase Angle Sensor

A method is considered for determining the error of a tracking angle digitizer with two-phase angle sensor not requiring the use of high-precision angle-measuring devices or devices for exact definition of the angular velocities of those angle sensors. The method provides immediate, clear, and complete monitoring of the conversion errors in real time with simple equipment of analog type.
