TL;DR: In this article, an electrically passive keyboard is provided with an array of keys, each of which cooperates with a plurality of coded shutters to intercept a beam of light passing from light projecting elements to light collecting elements.
Abstract: An electrically passive keyboard is provided with an array of keys. Each key is provided with an actuating bar which when depressed cooperates with a plurality of coded shutters. Each shutter is arranged to intercept a beam of light passing from light projecting elements to light collecting elements. Light pulses generated at a light source are coupled to the projecting elements with fiber optic cables. Decoding logic is coupled to the light collectors with fiber optic cables. Delay elements are provided in series in the fiber optic cables so that the decoding elements receives a plurality of binary coded light signals in a predetermined timed sequence which are converted into binary coded electrical signals at a point remote from the electrically passive keyboard.

TL;DR: In this paper, an electric signal transmission transducer employing a ferromagnetic amorphous ribbon and an electroacoustic signal conversion system using a Ferromagnetic Amorphous Ribbons is presented.
Abstract: An electric signal transmission transducer employing a ferromagnetic amorphous ribbon and especially an electric signal transmission element and system and an electroacoustic signal conversion system using a ferromagnetic amorphous ribbon. The transmission transducer also provides for applying a magnetic field to the ferromagnetic amorphous ribbon for controlling the electric signal transmission or delay time. Also shown are the electric and magnetic characteristics of ferromagnetic amorphous ribbons after various heat treatments in various magnetic fields.
