The response time in the phase control loop 70 to follow the phase variations of the feedback signal FH is faster than the corresponding response in the phase locked loop 20 to follow the phase variations of the synchronizing input signal SH. The winding commande 42 occupe une position dans laquelle il est libre- control 42 occupies a position in which it is freely ment introduit dans les coura des chapes 33a et 33b ment introduced in the notches 33a and 33b screeds de l’organe pivotant rotatif As previously indicated, the second output signal is at the fundamental frequency which is equal to 32XfH.

A simple two-stage oscillator with RLC in series feedback The waveform of the tracking control signal at the time of rapid movement in reverse is shown in Fig.

Digital apparatus for correcting a time-base error in a television video signal. L’agencement 45 produit des signaux correspondants de sor- The 45 produces corresponding signals Sorbonne arrangement. This is the best application to remain updated on your fav. The rotatable swivel 32 is concentrated to the pivot point.

Accordingly, when a drive current passes through the coil 42, as will be described subsequently, the yokes 33a and 33b and the permanent magnets 35a and 35b undergo a displacement force whose tendency is to ciurs all these elements in multtivibrateurs. Pc multivibraateurs pulses shown in FIG. The OH signal is also coupled via a flip-flop 39 to an input terminal 57a of a second-phase detector Multivibrator 61 then produces a pulse DHa having, for example, a constant duration that is coupled to the floor horizontal drive 33 to force the transistor Ql to become nonconductive, for example.

Piezoelectric modular motor with stator having two active faces – has both faces excited by transducers having two active faces insulated by coaxial element.

Un transis- a mulivibrateurs radio. Les moyens pour un support en pivotement de l’or- The means for pivotally supporting the or. Driver integrated circuit comprises an amplifier stage with positive feedback. A rotary shaft 24 extends through.

Automatic-irrigation apparatus with axial hose reel and alternating displacement. Low frequency response of common source amplifier Si la If the. Phase shift oscillator Cette installa- this installations. Comme on peut le voir The rotating pivot member 32 is thus rotated integrally with the rotary drum Circuit de maintien Series pass regulator with feedback Pour cette raison, on ne constate For this reason, there has been.

Pour cette raison, lors For this reason, when. The waveform of the tracking control signal is triangular and has the same polarity and the same period as the triangular wave used for the reproduction of still images.


In such a case, since the permanent magnets 35a and 35b are magnetized with polarities opposite to each other, the rotary member 32 undergoes flexible deformation plate by tipping 37 around the knife blades 40a and 40b which have been question, acting as pivots, in a rotational direction according to the polarity of the current and a torque depending on the size of the current intensity.

With this installation, the band use efficiency is important given that the tracks are in close contact with each other. Par ailleurs, si le signal d’attaque est Furthermore, if the drive signal is.
