Thyratrons, klystrons, and magnetrons I've heard
of, but trochotrons, charactrons, tonotrons I ain't heard of. That made this quiz
more of a learning exercise for me than a test of any sort of knowledge possessed.
Heck, I thought an 'ignitron' was a pejorative term for a really dumb techie wannabe.
In all there are 17 types of '-tron' devices given for which to match from a list
of descriptions. You'll probably do better than I did on this quiz that appeared
in the October 1963 issue of Electronics World magazine.
"-Tron" Teasers - An Electronic Quiz
By Robert K. Re
How many electronic devices do you know that end with the suffix "-tron"? Check
your knowledge of the field with this quiz.
Quite a few devices used in electronics today were named using the suffix "-tron"
(electron, cyclotron, etc.).
Out of the many words with this ending, can you match each
1. This special tube is used to generate TV test signals
when stations are off the air.
2. A gas-filled device, this counting tube is widely
used in digital circuits.
3. High currents are rectified in the electroplating
industry with this mercury-cathode diode.
4. Much older than a tunnel diode, this four-electrode
tube exhibits negative resistance in oscillator circuits.
5. Widely used in r.f. circuits, this u.h.f. transit-time
triode is called a "lighthouse" tube because of its shape.
6. Once fired, the grid in this gas-filled tube ceases
to have control over plate current until plate voltage is removed.
7. This is the general name for beam-switching tubes.
It describes the path of the electron in the tube.
8. Operating near absolute zero temperature, this super-conducting
switching element shows great promise for
9. This linear sweep generator, once triggered, will
keep itself turned on until the sweep is completed.
10. Crossed magnetic and electric fields are the key to the
operation of this high-power, high-frequency oscillator.
11. A new device, this special CRT is a direct-viewing storage
tube. Information can be stored for long periods, yet
12. This new class of computer circuits uses multiple phase
"clock" signals to perform majority logic operations.
13. Having one or more tunable cavities, this high-frequency
tube "bunches" the electrons to produce oscillations.
14. This neon lamp is capable of generating short bursts of
15. A special color CRT, this tube has only one gun and uses
phosphor strips in place of phosphor dots.
16. Using a special mask and beam-shaping plate, this CRT can
generate symbols on its face.
17. This new 12-pin subminiature, multi-function vacuum tube
is finding wide use in electronic equipment.
Popular Electronics published many quizzes over the
years (as did a few other magazines to a lesser extent) - some really simple and
others not so simple. Robert P. Balin created many of the quizzes. This
