using displaceable coupling elements, e.g. ferromagnetic cores, to produce change between different states of mutual or self-inductance

Full Title

Digital stores characterised by the use of particular electric or magnetic storage elements; Storage elements therefor (G11C14/00 - G11C21/00 take precedence) > using displaceable coupling elements, e.g. ferromagnetic cores, to produce change between different states of mutual or self-inductance
