Transformer-type displacement sensors containing discretely profiled sensing elements

The paper considers the design and primary data processing for transformer-type coordinate sensors having discretely profiled magnetic circuits of plate and cylindrical types. The sensors provide protection of the working windings from contact with the moving elements.Translated from Izmeritel'naya Tekhnika, No. 4, pp. 25–27, April, 1995.     

Information distribution at the output of angle encoders

We present analytic expressions for the density distribution for the information at the output of digital angle encoders. We show how the error in reproduction of quantization levels affects the basic information density distribution. Translated from Izmeritel'naya Tekhnika, No. 5, pp. 18–19, May, 1995.     

The experience of 1100 esophagoplasties

The experience of esophagoplasties in various benign diseases (566) and cancer (534) of the esophagus is outlined. The operation of choice now is extirpation of the esophagus by cervico-abdominal approach with one-state posterior-mediastinal esophagoplasty by the stomach or (in case of impossibility to form the graft from the stomach)--large bowel. If there are contraindications to such operation or in case of necessity of one-stage reconstruction of the pharynx the optimal operation is sub- and total bypass esophagoplasty by the large bowel.
