Josephson transitions based on new thick film technology are made. The main difference of the new technology is that the operation of a mould of ceramic slices in the forms combine with the operation of manufacturing of microcontour. In this case the silicon slices with a required microcontour in side walls of casting forms are pasted.

The paper is devoted to producing and studying magnetic properties of rapidly quenched neodymium-iron-boron based alloys (RQA). Extreme dependence of coercive force upon quenching ratio and alloy chemical composition (neodymium and boron content) is shown. Particles produced by quenching are shown to be X-ray amorphous and isotropic. By means of thermal influence it is possible to improve the magnetic characteristics of RQA and powders on their basis. The optimal annealing temperature is 600...800/spl deg/C. Composite magnets, produced from the above RQA have the following properties: B/sub r/=0,53 T, /sub i/H/sub c/=1100 kA/m.

The purpose of this study was to develop methods of brain tumor PDT, based on locoregional injection of photosensitive substance in liquor system. The first experience in performing this PDT procedure showed that it is well endured by patients with brain tumors. MRI and clinical examinations of patients 14 months after PDT revealed the absence of continued tumor growth. All this testifies to the favourable preconditions for further development and application of this treatment technique in neurooncology.

We determine the excitation conditions for the distributed generator with a ring resonator excited by several dependent sources. The resonator is formed by the segments of an artificial transmission line, and contains a distributed load, which can be provided by the plasma of the gas discharge maintained by the resonator field. The possible field patterns in a ring resonator are discussed.

A simple phenomenological model of changing asperity surface, in the process of thermal oxidation of polycrystalline silicon, is examined. This allows to prognosticate and consequently deliberately change electrical characteristics of the dielectric layer.

We report the technology of sandwich structure based on fullerene films and experimental results in research of optical and conductivity properties of sandwich samples. The single-crystal of sapphire [100] or silicon was used as a substrate. The sandwich specimens were based on structure M/C/sub 60/ fullerene film/M (M=Cr,Pd,Ag,Al,Cu). The thickness of fullerene films /spl sim/0.2-1.0 /spl mu/m. The area of C/sub 60/ film under the top contact /spl sim/1 cm/sup 2/. The specimens have been investigated in IR-spectroscopy, spectra-photometry, ellipsometry and XRD. The measurements of I-V characteristics and research in temperature dependence of conductivity were made as well. It was shown that metals as Cr, Pd, Ag, Al, Cu penetrates easy in fullerene film. It appears that specimens show the large value of conductivity. Silver/C/sub 60/ structure and other sandwich structures show semiconductor behaviour of conductivity.

The problem of distinguishability of state space model structures from input-output observations of the system is considered. We prove the proposition allowing to significantly simplify the system of algebraic equations solved in the symbolic form and, hence, to reduce the amount of required analytical computations. Two examples are given to illustrate the application of this approach.

The problem of digital controller design is discussed. The design method is based on the formation of two-time scale motions in the closed loop system. It is shown that, if a sufficient time-scale separation between the fast and slow modes in the discussed closed loop system and stability of fast modes are provided, then slow modes have the desired form. Thus, the output transient performance indices are insensitive to external disturbances. Relationships for control accuracy analysis and choice of the sampling period are obtained. Finally, an example with simulation results is presented.
