After the war, some of the inventions found new applications. The first transistor radio was released in 1954, and its manufacturing process made use of vacuum pumps. [43] The first integrated circuit or “chip” came to the market at the end of the 1950s, and vacuum pumps again played an important role in their production. These early ...
Edwards' IPUP2 Vacuum Pump Sets New Standards for Load Lock and Transfer Chamber Applications Advanced design of 2 nd generation pump achieves early success. CRAWLEY, England--(BUSINESS WIRE ...
A partial vacuum may be generated by increasing the volume of a container. To continue evacuating a chamber indefinitely without requiring infinite growth, a compartment of the vacuum can be repeatedly closed off, exhausted, and expanded again. This is the principle behind a positive displacement pump, for example the manual water pump. Inside ...
Most general pumps can increase as well as decrease the pressure of a gas; however, this category contains pumps that are usually exclusively used to decrease pressure. Wikimedia Commons has media related to Vacuum pumps .
Single-stage vacuum pumps typically produce vacuum to 35 torr (mm Hg) or 47 millibars (4.7 kPa), and two-stage pumps can produce vacuum to 25 torr, assuming air is being pumped and the ring-liquid is water at 15 °C (59 °F) or less. Dry air and 15 °C sealant-water temperature is the standard performance basis, which most manufacturers use for ...
A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the triode in 1906.
Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical circuits involving active components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.
Nole Floyd "Nokie" Edwards (May 9, 1935 – March 12, 2018) was an American musician and member of the Rock and Roll Hall of Fame. He was primarily a guitarist , best known for his work with The Ventures , [ 1 ] and was known in Japan as the 'King of Guitars' .
