The purpose of the invention is to reduce the sweat of rebral MOF. Figure 1 shows the functional diagram of the Converter; Fig. 2 is an electrical circuit of quantrons; FIG. 3 is a timing diagram of a rz-bots converter. The voltage converter in the code contains blocks 1 and 2 of the time interval conversion into a code, the voltage converter 3 in the time interval 5 photodetectors 4-7, elements IPI-NE 8-10, block 11 delay, element 12, elements OR 13-16, formers 17–19 for resetting quanta 20-27, emitter 28 for light optical harnesses 29, electro: optical switches for 30–39, formers 40 and 41 for pulses with the quantrons consisting of diode 42, the anode of which is input 43, transistor 44, LED 45, having optical outputs 46 and 47, photodetectors 48 and 49, later One of them has an input 50 and an optical input 51, a resistor 52 having an input 53, a photodetector 48 has an optical input 54. In the timing diagram, the voltage at the outputs corresponds to the number of blocks. Consider the operation of a two-unit converter. On. the input of the converter 3 is supplied with a transformable voltage, which is converted into a proportional pulse, which through the elements OR 3 and 15, the drivers 17 and 18 to the inputs 43 of quantrons and sets them to the zero state. Such a state will be the initial state of the quantrons. Quantrons work as follows When a electrical signal is simultaneously applied to the input 53 of the resistor 52 and the optical signal to the input of the photoreceiver 48, the transistor 44 opens, the quantron returns to the excited state, which is maintained for an arbitrarily long time due to the reverse optical coupling between the LED 45 and the photodetector A8. When a signal is applied to the input 43 or 682 of the simultaneous angular and electric signals at the inputs 50 and 51 respectively of the photodetectors 49, the transistor 44 is closed and the quanuron goes to the zero state. While the installation of the quantases in the initial state takes place, the pulse of the time interval arrives at the emitter 28, the light of which falls on the inputs of all the optical bundles 29 and propagates along their length. The lengths of the optical fiber through which the light enters the photodetector of 48 quantum dots 20–23 are chosen so that the light gets to the photodetector of the quantron 20 at time t after the start of the conversion, the photoreceiver of the quantron 21 is time 2, etc., i.e. if the conversion is carried out in the decimal number system (there are nine quantum dozens in each discharge), then the light gets into the photodetector 48 of the quantum 23 after 9T of time, after 9o of time the light can also fall on the photodetectors 5 and 6 of the device. After a time, a timed interval pulse through a delay block 11 and the element NOT 12 hits the elements OR-HE 8 and 9, opens all the electronic-optical keys, and the light hits the photodetector 4, the input of the element 1-ШИ-НЕ 8, by means of which electronic optical keys 35-39. Through 9T, the light enters the receiver 6. By means of the photodetector 5 and the element OR 34, the driver 40 generates pulses for enabling the excitation: the value of the next, not yet excited, next-generation quantum laser (conversion unit 2). ILmpile., Which produces a photodetector 5, falls on the element OR NOT 9, closes the electro-optical keys 30-34. After that, by means of the photodetector 4 and the element OR-HE 8, the electron-optical keys 35-39 are being torn. The device is ready for further transformations. After the light signal arrives at the photodetector 6 by means of the ILR 14 fop element, the finder 40 generates the next-bit excitation signal (conversion unit 2). At this time, the entry of light to the photoceramic 5 stops and, from its output, the signal enters the RSHI-HE element 9, by means of which the electro-optical keys 30-34 are opened. The photodetector 4, to the input of which light arrives, generates a signal that, through the element OR-NO 8, closes the electro-optical switches 35-39.

Upon receipt of an optical signal at the optical input and an electrical signal at the electrical input, the photodetector 7 generates a signal that arrives at the OR 16 element and the pulse former 41, which produces the excitation signal of the next not yet excited quantum laser of the next bit (conversion unit), and through the OR element 15, from the output of the photoreceiver 7, the signal is fed to the input of the imaging unit 18, which produces a reset pulse, resets the quantrons 24-27, preparing the conversion unit 2 for further conversion formation. Subsequent conversion units have a block diagram the same as conversion unit 2 and work similarly to it.

At the end of the time interval, the signal from the output of the OR-NOT 10 element is fed to the excitation inputs of the quantrons 20-23. When a signal is simultaneously applied to the optical inputs of the quantrons 20-23 and the signal arrives from the output of the OR-NOT 10 element, the quantrons of the conversion unit 1 are excited.

With the arrival of the signal from the element NO 2 (Fig. 3) on the elements OR-HE 8 and 9, by means of which all the electron-optical keys are closed, the light entering the quantrons 20-23 is stopped, the excitation of the quantrons is completed. From the output of the delay unit M through the element 12, the time interval signal is fed to the input of the pulse generator, which produces a reset pulse, which is fed to the electrical inputs 50 of the optical reset of all quantrons (except for quantrons 23 and 27) and resets them, except for the last excited quantrons of all bits Dov converter. Thus, only one quantron of the conversion unit remains in the unit state and the information is presented in the unit position code,

In the converter, the quantum dots of the first conversion unit are not excited for the entire conversion time, but only at the end of the conversion. Let Pn be the power consumed by a known transducer during the conversion time, P be the power consumed by one excited quitron, and if the numeration system is ten and an average of 4.5 quantarons are excited during the entire conversion time (power consumed by the element OR are NOT neglected, since the consumption of the dog takes place over a short time interval (delay time), then the power consumed by the proposed converter will be.
