Electronic engineering
carbon-paper recorder
Engineering; Electronic engineering
A recorder in which a signal-actuated stylus writes, by impression only, through a sheet of carbon paper onto a plain sheet underneath. This eliminates the need for an ink-carrying stylus.
barograph
Engineering; Electronic engineering
A recording barometer, using either a drum recorder (pen recorder) or a computer to store the data as a function of atmospheric pressure versus time.
dot matrix
Engineering; Electronic engineering
A rectangular array of spaces, some of which are filled in to form alphanumeric and punctuation characters.
chromaticity diagram
Engineering; Electronic engineering
A rectangular-coordinate graph in which one of the three chromaticity coordinates of a three-color system is plotted against another coordinate.
contact rectifier
Engineering; Electronic engineering
A rectifier consisting of two dissimilar materials in direct contact. Examples: copper and copper oxide, magnesium and copper sulfide, selenium and aluminum, and germanium and indium.
copper-oxide rectifier
Engineering; Electronic engineering
A rectifier in which the semiconductor material is copper oxide. Rectifiers of this type are suitable for low-voltage ser- Semiconductor disk Current flow − Magnetic field
copper-sulfide rectifier
Engineering; Electronic engineering
A rectifier in which the unilateral junction is between copper-sulfide and magnesium elements. Like the copper-oxide rectifier, the copper-sulfide unit was once widely used in low-voltage ...
