DIFF Subgroup
H03K 19/185 using dielectric elements with variable dielectric constant, e.g. ferro-electric capacitors
Introduced: July 1974
Full Title
Full titles differ between systems:
IPC:
Logic circuits, i.e. having at least two inputs acting on one output; Inverting circuits > using specified components > using dielectric elements with variable dielectric constant, e.g. ferro-electric capacitors
CPC:
Logic circuits, i.e. having at least two inputs acting on one output (circuits for computer systems using fuzzy logic G06N7/02); Inverting circuits > using specified components (, H03K19/003 - H03K19/0175 take precedence) > using dielectric elements with variable dielectric constant, e.g. ferro-electric capacitors
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
IPC defines codes here since 1974.
