Magnetostrictive thin film delay line

Claim 1

AN INFORMATION CONTROL CIRCUIT COMPRISING: AN ELONGATED PLANAR BIAXIAL ANISOTROPIC THIN MAGNETIC FILM HAVING A FIRST EASY AXIS OF REMANENT FLUX ORIENTATION TRANSVERSE WITH RESPECT TO THE LONGITUDINAL AXIS THEREOF AND A SECOND EASY AXIS OF REMANENT FLUX ORIENTATION ALONG THE LONGITUDINAL AXIS OF SAID FILM; SAID FILM EXHIBITING A FIRST MECHANICALLY INDUCED ANISOTROPHY DIRECTED ALONG THE FIRST EASY AXIS OF SAID FILM AND A SECOND MECHANICALLY INDUCED ANISOTROPHY DIRECTED ALONG THE SECOND EASY AXIS OF SAID FILM IN RESPONSE TO MECHANICAL TENSION AND COMPRESSION APPLIED ALONG ITS LONGITUDINAL AXIS, FIRST MEANS COUPLED TO SAID FILM FOR PROPAGATING ALTERNATE STRESSES OF COMPRESSION AND TENSION ALONG THE LONGITUDINAL AXIS OF SAID FILM HAVING A MAGNITUDE SUFFICIENT TO ORIENT THE MAGNETIZATION OF EACH PORTION STRESSED ALONG THE FIRST OR SECOND AXIS OF INDUCED ANISOTROPY; MEANS FOR APPLYING A MAGNETIC BIAS FIELD IN THE PLANE OF SAID FILM DIRECTED ALONG THE FIRST EASY AXIS, COINCIDENTLY OPERATIVE, WHEN ANY PORTIONS OF SAID FILM EXHIBITS SAID FIRST MECHANICALLY INDUCED ANISOTROPY, TO ESTABLISH SAID PORTIONS IN A DATUM STABLE STATE OF MAGNETIZATION ALONG THE FIRST EASY AXIS; AND CIRCUIT MEANS COUPLED TO DIFFERENT PORTIONS OF SAID FILM FOR ENTERING AND PROVIDING AN OUTPUT FOR A BINARY VALUE COMPRISING; AN INPUT CIRCUIT COUPLING A FIRST PORTION OF SAID FILM, OPERATIVE WHEN SAID FIRST PORTION EXHIBITS SAID SECOND MECHANICALLY INDUCED ANISOTROPY, FOR APPLYING A FIELD DIRECTED ALONG THE SECOND EASY AXIS THEREOF TO CONJOINTLY ESTABLISH SAID FIRST PORTION IN ONE OR AN OPPOSITE STABLE STATE ALONG SAID SECOND EASY AXIS TO THEREBY DEFINE DIFFERENT BINARY VALUES.
