deflection yoke

Deflection yokes are sometimes faulty.

This yoke has similar, if not identical inductances, unlike a TV deflection yoke.

These focus coils are essentially as long as the tubes themselves, and surround the deflection yoke (coils).

If otherwise, it indicates that the voltage isn't increasing linearly, and therefore that the magnetic field produced by the deflection yoke is not linear.

Production commenced for electronic tuners, deflection yokes, flyback transformers and capacitors 1979 Feb.

These active compensation circuits use the deflection yoke to finely adjust beam deflection according to the beam target location.

Rather than use sawtooth waves to direct the internal electron beam in a raster pattern, computer-controlled integrators feed linear amplifiers to drive the deflection yoke.

The electron current sweep is aimed using wound copper coil magnetic deflection yokes, as in a cathode ray tube (CRT).

On the wave's "ramp", the magnetic field produced by the deflection yoke drags the electron beam across the face of the CRT, creating a scan line.

In detail, scanning of CRTs is done by magnetic deflection, by changing the current in the coils of the deflection yoke.

The circular "bulls-eyes" in the centre and the four corners permitted uniform deflection yoke and oscillator amplitude adjustments for centering, pincushioning, and image size.

Instead of the deflection plates of a typical CRT, it had a unique structure they called an electrostatic deflection yoke, with metallized electrodes inside a glass cylinder.

Furthermore, wide-deflection-angle CRTs need horizontal sweeps with current that changes proportionally faster toward the center, because the center of the screen is closer to the deflection yoke than the edges.

A demonstration of a vector-drawing cathode ray tube display was made by connecting the deflection yoke in a standard television to the channels of a stereo amplifier fed with music program material.

(In detail, coils in a deflection yoke extend some distance beyond the neck of the tube, and lie close to the flare of the bulb; they have a truly distinctive appearance.)

Delta-gun CRTs required the electronically driven convergence coils placed on a "triangle" device on the deflection yoke, powered from the deflection oscillators through a complex set of tunable electromagnetic coil, capacitors and resistors.

These movable weak permanent magnets are usually mounted on the back end of the deflection yoke assembly and are set at the factory to compensate for any static purity and convergence errors that are intrinsic to the unadjusted tube.

In a cathode ray tube (CRT) display, when the electron beams are unblanked, the horizontal deflection component of the magnetic field created by the deflection yoke makes the beams scan "forward" from left to right at a constant rate.

In electronics, these (usually steady-rate) movements of the beam[s] are called "sweeps", and the circuits that create the currents for the deflection yoke (or voltages for the horizontal deflection plates in an oscilloscope) are called the sweep circuits.

However, the entire structure of the cathode, deflection yokes, anode and overall vacuum tube size is much larger, therefore made out of steel, not glass, with the main central open midsection of the vacuum tube hollow, leaving room for the scan table and object or person to lie while the scan is performed.
