From what products does the electron tube manufacturing industry derive its greatest profits?
Over three-fourths (76 percent) of the value of industry revenues in the late 1990s was derived from the production of new and rebuilt receiving-type electron tubes such as TV and cathode-ray tubes
When was the electron tube invented?
Lee De Forest invented the electron tube in 1906.
How big is the electron tube industry?
Total industry shipments declined from $3.82 billion in 1999 to $3.56 billion in 2000, while the cost of materials increased from $2.08 billion to $2.21 billion
What is the positive electrode of an electron tube?
anode
Is cathode ray tube and electron tube same?
Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.
How may the electron tube industry be said to have thrived in the 1990s?
Between 1994 and 1999, the value of PC system sales (which included a CRT monitor) grew by almost 77 percent.
What does tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
How a tube light formed?
tube light us formed by sum inerts gasses like neon because they do not react with electron and the friction between electron and neon produced light.
What does vacuum tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
What is the use of shell and tube heat exchangers?
shell and tube heat exchangers are used mostly in the chemical processing industry for heating, cooling, condensing, and evaporating highly corrosive liquids and gases. AMETEK Fluoropolymer Product shell and tube heat exchanger was the first heat exchanger developed using fluoropolymer tubes and the patented honeycomb tube to tube sheet joint which has been successfully used for over 55 years. Sulfuric Acid is the chemical most used with Ametek Fpp heat exchangers. The process of making sulfuric acid can vary, but any company dealing with the manufacturing process has a high potential for the use of a fluoropolymer heat exchanger in their process. Other Acids commonly requiring fluoropolymer heat exchangers are Hydrochloric, Nitric and Hydrofluoric Acids. Another chemical manufacturing industry fluoropolymer heat exchangers are used in is the Chlor-Alkali manufacturing process.
What is the evidence that an electron carries an electric charge?
the deflection of an electron beam in a cathode ray tube by electric and magnetic feilds.
What is filament current?
The current supplied to the filament of an electron tube for heating.
