DEFINITION

Classification: 327/366

Superconductive (e.g., cryogenic, etc.) device:

(under subclass 365) Subject matter including a switching circuit which operates at a very low temperature (e.g., 30 K) where the electrical resistance becomes essentially zero.

(1) Note. This subclass comprises superconductive devices which operate at a temperature less than or equal to 30 K; Class 505 comprises superconductive devices which operate at a temperature higher than 30 K.
