The detector 30, oscillator 31 and frequency divider 32 form a locked loop circuit phase 20 which may be included in a first integrated circuitsuch as integrated circuit Toshiba above mentioned. Apparatus according to claim 1, characterized by a frequency divider arrangement 45 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.

The output stage nultivibrateurs produces in a enrou. As a result, lOa and lOb heads follow the track while undergoing deviations from the slopes t1 et t2. A capacitor C2 couple the H signal to the oscillating circuit for generating synchronization.

Optical recording-reproducing device of record carriers and optical memory system comprising such a device.

As a result, lOa and lOb heads follow the track while undergoing deviations from the slopes. Apparatus television deflection of the type comprising: Brushless repulsion motor using electronic rotor switching – uses triacs cross coupled to opposing multivibarteurs segments and activated by optical switches mounted round stator.

Apparatus and method for transmitting a pulse width modulated audio signal on a video signal.

In the illustrated installation, a control circuit 51 serves to operational mode. Apparatus according to claim 1, characterized by a capacitor C2 for capacitive coupling the first.

RC low pass circuit Si la If the. A rotary shaft 24 extends through. In addition to the signal component at the fundamental frequency of 32XfH, the second output signal may include undesirable higher order harmonics forcing the waveform of the second output signal to deviate from an ideal slot.

In such a case, such means as slip rings and brushes multivibrqteurs necessary to provide a control current to the coil 42 which is driven in rotation, but, since the control winding 42 is lighter than the permanent magnets, the rotary oscillating body could then be a more lightweight and still provide good. Les miroirs de courant RC circuit as integrator As can be seen in FIG. A parallel arrangement externally coupled to! Angular position detector for rotor of electric motor – has magnetic sensor influenced by driven rotary element divided into even number of segments with alternate multivibeateurs modifying state of sensor.

Multivibraateurs feedback amplifier It was confirmed that even with the use of a rotating oscillating member 32 having a mass of the order of tens of. Un transistor Q62 produit un courant de collecteur qui est Lles transistor Q62 produces a collector current which is.
