  • CONNECTION OF HIGH-PERFORMANCE PULSE DISCHARGE PLASMA GENERATOR, ESPECIALLY FOR MAGNETRON SPUTTERING
    Publication number: 20230124940
    Abstract: Connection includes transistor, transistor exciter controlled by the frequency generator and/or programmable unit, the power source of voltage, the unit with capacitors. The voltage power source is connected to the transistor through the unit with capacitors. The stabilizing non-inductive resistor is connected to the power supply branch for the magnetron with transistor. The power stabilizing non-inductive resistor is a resistor with the wire wound by Ayrton-Perry-type winding and/or the resistor with low value of the parasitic inductance on the basis of thin layers. The electronic control circuits of the gate of the transistor include a frequency generator with the cut-off switch and with support elements and also include an exciter with support elements. The connection with the stabilizing non-inductive resistor is used in case of the bipolar and/or multi-circuit pulse plasma generator. The depolarization voltage is led from the outside source through the capacitor to the depolarization block.

  • Method to suppress blood coagulation in the circuit of the device substituting the kidney function and apparatus realizing this method
    Patent number: 8529489
    Abstract: A method and device for reducing blood coagulation in the circuit of a device for substitution of the kidney function wherein, prior to the input in the device for substituting the kidney function, the blood which left the patient's body is cooled down to a temperature in the range 10° C. to 30° C. and, as the blood passes the device for substitution of the kidney function, that blood is warmed up to a temperature at least near to the body temperature and then it is returned in the patient's body.
