gate(redirected from -gate)
Also found in: Dictionary, Thesaurus, Medical, Wikipedia.
a projection on a casting; a piece of metal that has hardened in the gating. After being separated from castings, gates are used in the burden in smelting metal.
(Russian, shiber), a closing device in the form of a slide or damper, used to open or close a channel for the flow of liquids or gases. Gates include draft-regulating dampers in the flues of industrial furnaces and boiler installations as well as sluice gates designed to shut off water-intake channels from a river or to close connections between channels. The working member of a slidingvane pump is also a type of gate. Small gates are operated manually; large gates are operated by toothed racks, worm drives, and the like.
What does it mean when you dream about a gate?
Gates represent entrances to a new place or new circumstances in life. They also symbolize the “exit” from old, unwanted conditions. (See also Door.)
ii. The point at which a commercial flight starts.
iii. A removable lock to limit the maximum travel of the throttle under normal conditions.
iv. The position on an extended runway centerline where inbound aircraft are required to pass at a time assigned by approach control.
v. The range of the fuel-air ratio through which combustion can be started. This normally ranges from 1:18 to 1:8. See also fuel-air mixture.
vi. In air interception terminology, it means to fly at a maximum speed for a limited period.
[Sammet 1969, p. 139].
In a CPU, the term applies particularly to the buffers that route data between the various functional units. Each gate allows data to flow from one unit to another or enables data from one output onto a certain bus.
gate(1) A switch that is opened or closed.
(2) A group of transistors that makes up an AND, OR or NOT Boolean logic gate. See Boolean gates, logic gate and gate array.
(3) In a field effect transistor (FET), the gate is the element that acts as a trigger to cause the transistor to switch. In a bipolar transistor, the gate is called the "base." See transistor, FET and MOSFET.

|The gate is the trigger line. When pulsed, an electromagnetic field causes the switch to close.|
