Method for adjusting the electrical parameters of the articles of the type R̅C̅-̅0̅ in the manufacturing process thereof

The invention relates to electronics, namely to methods for adjusting the electrical parameters of the articles of the typein the manufacturing process thereof, and can be used in the fields of construction of accurate measurement devices, computer engineering and in the manufacture ofg phase-shifting elements and elements for selecting circuits.The method for adjusting the electrical parameters of the articles of the typein the manufacturing process thereof comprises selection as an electrical parameter of a preset time constant τ0 in the manufacture of the article of the typeof more than two coaxial microwires n, prefabrication of the article of n-1 microwires, connected in parallel, which is the time constant τn-1, thermal treatment of the prefabricated article, measurement of the real time constant value τr thereof, determination of the desired value of the time constant τx of thedeferred coaxial microwire, winding of the deferred coaxial microwire with the time constant τx onto the prefabricated article, simultaneous measurement of the time constant of the deferred microwire wound until the attainment by the time constant of the value τx and its connection in parallel to the n-1 microwires, forming an article of the typewith a preset time constantτ0= τr+τx. Invenţia se referă la electronică, şi anume la metodele de ajustare a parametrilor electrici ai pieselor de tipîn procesul de confecţionare a lor, şi poate fi utilizată în domeniile construcţiei aparatelor de precizie, tehnicii de calcul şi la confecţionarea elementelor de defazaj şi elementelor pentru circuite selective.Metoda de ajustare a parametrilor electrici ai pieselor de tipîn procesul de confecţionare a lor include selectarea în calitate de parametru electric a unei constante de timp prestabilite τ0 la confecţionarea piesei de tipdin mai mult de două microcabluri coaxiale n, prefabricarea piesei din n-1 microcabluri, unite în paralel, care constituie o constantă de timp τn-1, prelucrarea termică a piesei prefabricate, măsurarea valorii constantei reale de timp τr a acesteia, determinareavalorii necesare a constantei de timp τx a microcablului coaxial rezervat,bobinarea microcablului coaxial rezervat cu constanta de timp τx pe piesa prefabricată, măsurarea concomitentă a constantei de timp a microcablului rezervat bobinat până la atingerea constantei de timp a valorii τx şi unirea în paralel a acestuia cu cele n-1 microcabluri, formând o piesă de tipcu o constantă de timp prestabilită τ0= τ
