inhibitor

[in′hib·əd·ər]
(aerospace engineering)
A substance bonded, taped, or dip-dried onto a solid propellant to restrict the burning surface and to give direction to the burning process.
(chemistry)
A substance which is capable of stopping or retarding a chemical reaction; to be technically useful, it must be effective in low concentration.

Inhibitor

 

a circuit having m + n inputs and a single output, at which a signal can appear only when there are no signals on the m inputs (inhibiting). The other n inputs (principal) form one of the two logic connections, “AND” or “OR.” Inhibitors are used extensively in computers. They are very often understood to be a circuit having a single principal input and a single inhibiting input. A signal appears at the output of such a circuit when a signal is present on the principal input but there is none on the inhibiting input. Such an inhibitor is called an anticoincidence gate; its conventional representation is given in Figure 1.

inhibitor

A substance added to paint to retard drying, skinning, mildew growth, etc. Also see corrosion inhibitor, inhibiting pigment, drying inhibitor.
