At controllers testing for various subsystems of compound objects when the application of standard measuring instruments or systems is impossible, it is often necessary to develop additional sensors resistant to external influences, in particular to vibrations and noises. The devices presented in the paper reflect the recent experience of such problems solution in the Institute of Control Sciences.

Semenov V. S. Investigation of the domain structure in a thin-film magnetic recording head
The change in the domain structure of a ferromagnetic strip used as a magnetic conductor in thin-film magnetic recording and sensing heads is examined. The paper shows that under the exposure of homogeneous external field along the longer side of the strip, the domain walls splitting the strip into domains shift and remain uncharged, while a magnetization zone appears at the edges of the strip. This zone turns out to be a magnetic leakage field source for the thin-film magnetic head’s record.

The paper analyzes the conductance characteristics changes of multi- and single-layer carbon nanotubes and their grids in the temperature range from the room temperature up to 200°C. The structures’ conductance temperature dependency is shown. General patterns of conductance decrease in various structures are discovered. A mechanism of thermally initiated carrier transfer in the zone of nanotube contact with the electrode is proposed that prevails over desorption processes under atmospheric conditions.

Taimanov R. E., Sapozhnikova K. V., Lukashev A. P., Pronin A. N. Quality control in advanced reliability sensors manufacturing
The necessity of quality management system improvement at the plants manufacturing sensors with normalized long-term calibration period is justified. The paper notes that the special validation of the manufacturing process underpinned by additional control results confirms the realizability of the normalized calibration interval. Additional control should include process stability tests (low scatter of sensor parameters’ change rates) and accelerated tests justifying the specified calibration interval. Additional control can be organized based on the analysis of error changes within the range significantly smaller than the standardized error value for the manufactured sensors. The necessity and comprehension of additional control are illustrated with practical case studies.
