Aluminum sacrificial anodes (light colored rectangular bars) mounted on a steel jacket structure. Zinc sacrificial anode (rounded object) screwed to the underside of the hull of a small boat. Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an ...
Schematic symbol used in circuit diagrams for a vacuum tube, showing control grid. The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode.
Turn off is accomplished by a negative voltage pulse between the gate and cathode terminals. Some of the forward current (about one-third to one-fifth) is stolen and used to induce a cathode-gate voltage, which in turn causes the forward current to fall, and the GTO will switch off (transitioning to the blocking state).
A silicon-controlled switch (SCS) behaves nearly the same way as an SCR; but there are a few differences. Unlike an SCR, an SCS switches off when a positive voltage/input current is applied to another anode gate lead. Unlike an SCR, an SCS can be triggered into conduction when a negative voltage/output current is applied to that same lead.
In May 1942, the U.S. government assigned Curtiss-Wright a defense production factory for wartime aircraft construction at Louisville, Kentucky, to produce C-76 Caravan cargo aircraft, which was constructed mostly of wood, a non-priority war material. After difficulties with the C-76, including a crash of a production model in mid-1943, as well ...
Main Terminal 1 (MT1) and Main Terminal 2 (MT2) are also referred to as Anode 1 (A1) and Anode 2 (A2) respectively. [ 2 ] The relative sensitivity depends on the physical structure of a particular triac, but as a rule, quadrant I is the most sensitive (least gate current required), and quadrant 4 is the least sensitive (most gate current required).
The Chrysler Town & Country, released in 1990, was a more luxurious repackaged version of the Caravan and had no manual transmission option. Manual transmissions were not available on V6 models of the passenger Caravan, but were an option on the Mini Ram Van and Caravan C/V's long-wheelbase models with a 3.0 L V6. [citation needed]
The YC-76. The first flight of the YC-76 prototype took place on 3 May 1943. [2] The C-76 proved severely underpowered from the start, with a cruising speed of 160 mph (260 km/h), a service ceiling of 22,600 feet (6,900 m), a range of only 750 mi (1,210 km), and a cargo capacity of under 8,000 lb (3,600 kg).
