The impregnated cathode is made up of a first sintered porous element whose surface functions as an electron emitting region and a second sintered porous element whose surface is a peripheral region other than the electron emitting region. The porosity of the first sintered porous element is ...
Sutures are made up of : View Solution In the electrolysis refining of blister copper , a thin strip of pure copper is used as ___. View Solution (a) Describe the method of refining crude nickel metal. (b) Name the common element present in the anode mud in electrolytic refining ...
Deflection is possible, however, only up to a maximum angle α, such that (11.3)αLd+θ+θL=12d From these three expressions, certain quantities fundamental to the rating of a cathode-ray tube with electric field deflection can be derived. 11.8.1.3 Definition This is the maximum sweep of ...
CONSTITUTION:A cathode 30 is made up out of a laminated configuration composed of 2 layers of a transparent indium oxide tin (ITO) film 32 and a transparent conductive film 34 furnished with anti-sputtering properties. The ITO film 32 is provided as a bed for the back surface plate side ...
A solid cathode in a fused salt electrolytic cell for the production of aluminum is made up of individually exchangeable elements (10). These cathode elements are made up of two parts which are rigidly joined together and which are resistant to thermal shock. The upper part (12) which project...
X-ray tube with regulator ca 1904 On the tube is etched; G.M. no.298815 and probably made by the company of Franz Schilling from Gehlberg Germany. This tube has a bulb diameter of 10cm and has a regulator with mica plates, which was an "automatic"regulator. When the tube gets "...
This very tiny CRT pictured above, was made using 3mm outside dia. glass tubing. It's face can fit loosely inside a 1/8" hole. The cathode (visible on the far end) is made of 1/16" dia. aluminum tubing. It also serves as the evacuation tube. ...

This gauge is referred to as the pressure indicator. The order of magnitude of pressure in a vacuum system can be appreciated over the range of about 2666.6 to 10−1 Pa (20–10−3 Torr) by setting up a glow discharge in the residual gas. For that purpose, a glass tube with metall...
(q/rratio) of Na+is lower than Li+in solid materials and in certain cases the diffusion of Na+in solid phases is much faster than Li+, thus allowing a fast-charging up to 500 °C current rate (58.5 A.g−1) as recorded by Yang et al.13Despite the higher molar mass of Na, ...
