Caption: Figure 2: Distribution of the emission's current densities in the penetration channel during excitation of a non-self-sustaining discharge: [j.sub.t0] is the density of the thermionic
current; [j.sub.t] is the current density, accounting for the Schottky effect.
-- Carex Health Brands has acquired Thermionic
Corp.'s ThermiPaq hot and cold therapy line.
On the other hand, as the energy source in the TWT is the electron beam that emits from a thermionic
cathode, the power is limited by maximum current density.
As for algorithms S I once had to reproduce a diagram of a thermionic
SEMs use high-temperature tungsten wire filaments to emit electrons.
This author has analyzed the chronological timelines of numerous scientific discoveries, including these: Euclidian Geometry, Newton's derivation of fluxions (calculus), Newton's development of a theory of universal gravitation, unified geometry, thermionic
emission, and Pauli's exclusion principle in physics (Harmon, 1973).
Their new wireless sets were built around thermionic
valve or vacuum tube technology.
The Lane-Emden type equations describe a variety of phenomena in theoretical physics and astrophysics, including the aspects of stellar structure, the thermal history of a spherical cloud of gas, isothermal gas spheres, and thermionic
It was shown  that thermally assisted tunnelling, and not thermionic
emission, dominates carrier injection into 1D semiconductors.
Having had Sir John Ambrose Fleming, the inventor of the thermionic
valve, as the first chair of electrical technology in the late 1800s, UCL built on this pioneering work, often with Marconi, in the following years.
The EISA judges awarded the HT--E6750W Best in Class not just because it is "bridging the generations between thermionic
valves and modern Class D amplification," but also because the combination of its features and functionalities ensures endless home entertainment enjoyment.
