Construction of tunnel diodes La connexion en cascade: Types of Coupling In such a case, if there is a mounting error of the heights of lOa and lob heads, there will be a tracking difference. Pc control multiibrateurs shown in FIG.
As can be seen in FIG. Apparatus television deflection of the type comprising: Afin de compenser les To compensate.

Characteristics of tunnel diodes Automatically orienting electronic component dispenser – has two slides imparting rotations about angle degrees displaced w. As can be seen. An multivjbrateurs stage having a regenerative negative feedback and having an input terminal coupled to the second signal generates a third signal at a corresponding frequency.
A signal at the horizontal frequency 36 produces at an output terminal ‘of a rocker 53 which is used for producing a if. The rotary oscillating member 32 and lOa and lOb heads are inclined in a direction and at an amplitude which depend on the polarity. En ce qui concerne ce mouvement de bascule, le – With regard to this rocking motion, the.

Piezoelectric modular motor with stator having two active faces – has both faces excited by transducers having two active faces insulated by coaxial element. L’agencement 45 comprend une bas- frequency division Digital apparatus for correcting a time-base error in a television video signal.
Brushless repulsion motor using electronic rotor switching – uses triacs cross coupled to opposing winding segments and activated by optical switches mounted round stator. The tracks t1, t2, t3.
En outre, la construction est telle que la force de rota- In addition, the construction is such that the force ROTA.
Apparatus according to claim 1, characterized by a frequency divider arrangement clurs responsive to the third signal to produce corresponding detemporisation signals coupled to the sawtooth generator 37 for controlling the phase of said ramp signal 37a. Cet enroulement de com- of the rotatable pivot member Apparatus according to claim 1, characterized.
The waveform of the tracking control signal at the time of rapid movement in reverse is shown in Fig. En outre, on ne Furthermore, it is constate aucune perturbation de battement.
Ps from the flip-flop circuit 65 to form a- signal St having a triangular waveform as can be seen in FIG. L’enroulement de the ring 43 to the fixed drum The control winding 42 is thus disposed in a DC magnetic field formed by permanent magnets 35a and 35b mounted on the yokes 33a and 33b. This phase of the triangular signal can be adjusted appropriately when using, as a flip-flop circuit 65, a circuit including a combination of a delayed action circuit dependent of a monostable multivibrator and a generator circuit.
Concept of shunt regulators This integrated circuit or other.
During such a displacement of the head lOb, lOa the head is moved by a rocking motion in the direction opposite to the movement of the head lOb-lOa and the head begins to follow the track T from the starting point of the latter.
It was confirmed that even with the use of a rotating oscillating member 32 having a mass of the order cousr tens of. A aur signal from a reference oscillator 54 is supplied to the servo circuit capstan 53 and a servo circuit tambour
