Vacuum tubes and sprytrons are some of the electronic switching and amplifying devices based on vacuum conductivity.

Category: Vacuum tubes

Vacuum tubes use the flow of electrons to manipulate electrical signals, and they played a critical role in the development of electronics technology.

Vacuum tubes are still used in some specialist applications such as high power RF amplifiers, cathode ray tubes, specialist audio equipment and some microwave devices.

* Vacuum tubes create a distortion, the so-called tube sound, that some people find to be more tolerable to the ear.

Vacuum tubes are obsolete in consumer electronics, having been replaced by solid-state devices.

Vacuum tubes are thus used for rectification, amplification, switching, or similar processing or creation of electrical signals.

Vacuum tubes were critical to the development of electronic technology, which drove the expansion and commercialization of radio broadcasting, television, radar, sound reinforcement, sound recording and reproduction, large telephone networks, analog and digital computers, and industrial process control.

Vacuum tubes, which could be used for switching, made electronic computing possible for the first time, but the cost and relatively short mean time between failure of tubes were limiting factors.

Vacuum became a valuable industrial tool in the 20th century with the introduction of incandescent light bulbs and vacuum tubes, and a wide array of vacuum technology has since become available.

Vacuum pumps were added to the tubing systems, and preheaters were developed to recycle heat lost in the steam.

* Vacuum channel transistor: In 2012, NASA and the National Nanofab Center in South Korea were reported to have built a prototype vacuum channel transistor in only 150 nanometers in size, can be manufactured cheaply using standard silicon semiconductor processing, can operate at high speeds even in hostile environments, and could consume just as much power as a standard transistor.

Vacuum Tube Voltmeters or valve voltmeters ( VTVM, VVM ) were used for voltage measurements in electronic circuits where high impedance was necessary.

The vans of the British Vacuum Cleaning Company ( BVCC ) were bright red ; uniformed operators would haul hose off the van and route it through the windows of a building to reach all the rooms inside.

The only significant additions to the game's engine were the Jjaro ship, multiple paths between levels, a new rapid-fire weapon that could be used underwater, and vacuum-enabled humans carrying fusion weapons ( called " Vacuum Bobs " or " VacBobs ").

Once there were several industries in and around the town, including Ronson's Lighters and Goblin Vacuum Cleaners.

Vacuum tubes were the dominant active electronic components in amplifiers manufactured from the 1930s through the early 1970s, and tube amplifiers continue to be preferred by some professional musicians.

Vacuum tubes ( valves ) were by far the dominant active electronic components in most instrument amplifier applications until the 1970s, when semiconductors ( transistors ) started taking over for performance and economic reasons, including heat and weight reduction, and improved reliability.

Vacuum tube amplifiers were used in the UNISERVO tape drive for the UNIVAC I computer.

Vacuum cleaners at that time were exceptionally noisy.

During their later life, some locomotives were fitted with Dual ( Air and Vacuum ) Brakes.

Shortly before the scheduled second flight of the Falcon 9, two cracks were discovered in the-long Merlin Vacuum niobium alloy sheet nozzle.

Vacuum cleaners and front loaders were replaced with imported products, the plastic moulding production was contracted out, the factory was being stripped of production, volume and jobs.

Vacuum brakes were introduced as a result of the accident.

The album's second and third singles were " Love in a Vacuum " and " Looking over My Shoulder "; the latter peaked at No. 61 on the Billboard Hot 100.

The Monitor reveals that their calculations were used to model Charged Vacuum Emboitments ( CVEs ) as a means of excising off excess entropy from this universe into others as to stave off the imminent heat death of the universe ; without the calculations, the CVEs have disappeared.

The visual output of these games can range from a few small light bulbs or LED lights to calculator-like alphanumerical screens ; later these were mostly displaced by liquid crystal and Vacuum fluorescent display screens with detailed images and in the case of VFD games, color.

Vacuum tubes were developed for long-distance telephone networks and radio transmission and were later used for electronic computers.

Vacuum tanks were installed on trailers to control their integrated braking systems.

" Vacuum " is one of the few words in the English language that contains two consecutive ' u's .< ref name = double_u >

Vacuum metal deposition using gold and zinc has been shown to be non-specific, but can detect fat layers as thin as one molecule.

") Between 1950 and 1952, he variously worked as a door-to-door salesman for the Electrolux Vacuum cleaner company, as a Gunther Beer truck relief driver, where he achieved a certain fame for burning out three truck clutches in six weeks, and as a ticket agent for United Airlines, all before escaping into the United States Air Force, where he ultimately became head of the Policy Branch of the USAF Psychological Warfare Division, about which he would write in his humorous autobiography, Which Way to Mecca, Jack ?, that his " principal achievement " was in formulating the principle that " a 500-pound sack of propaganda leaflets, if dropped from an altitude of 13, 000 feet and provided it scored a direct hit, would drive one North Korean soldier approximately four feet into the ground.

Between One Human Minute and A Perfect Vacuum, he reviews 19 fictional books ( and one fictional lecture ).

* The Vacuum Gun: Enlists the help of Batty-Man, Riff Raff, Electric Eel, and the gangs that each one led to pull crimes all over the world.

Two matched transistors of the same polarity ( or, less often, Vacuum tubes ) can be arranged to supply opposite halves of each cycle without the need for an output transformer, although in doing so the driver circuit often is asymmetric and one transistor will be used in a Common-emitter configuration while the other is used as an Emitter follower.

* Each Bruce " 4 pack " has its own Vacuum Building, while Pickering has one per eight reactors.

Today, Futabas two main products lines are radio controls on the one hand and press die set components, mold base components and VFD ( Vacuum Fluorescent Displays ) modules.
