    en.wikipedia.org/wiki/Gate_valve

    Gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber ...

    en.wikipedia.org/wiki/Gate_array

    A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a prefabricated chip with components that are later interconnected into logic devices (e.g. NAND gates, flip-flops, etc.) according to custom order by adding metal interconnect layers in the factory. It was popular during the ...

  8. Four-phase logic - Wikipedia

    en.wikipedia.org/wiki/Four-phase_logic

    The output C becomes valid during this time – and therefore, a 1 gate output can't drive another 1 gate's inputs. Hence 1 gates have to feed 3 gates, and they, in turn, have to feed 1 gates. One more thing is useful – 2 and 4 gates. A 2 gate precharges on ϕ1 and samples on ϕ3: and a 4 gate precharges on ϕ3 and samples on ϕ1.
