摘要: An improvement of a process for producing a magnetic recording medium comprising coating a non-magnetic support with a magnetic paint comprising a magnetic layer forming component containing ferromagnetic powder and a resin component dispersed in an organic solvent and drying the coated layer. The improvement resides in the preparation of the magnetic paint. In the improvement, the magnetic paint is obtained by kneading said magnetic layer forming component and a first solvent having a solubility parameter of not lower than 9.5[cal..multidot.cm.sup.-3 ].sup.1/2 as measured by Small method and adding a second solvent to the resulting kneaded product so that the mixed organic solvent in the magnetic paint has a solubility parameter of lower than 9.5[cal.multidot.cm.sup.-3 ].sup.1/2 to thereby disperse the magnetic layer forming component in the organic solvent.

摘要: An input light signal is guided to a light receiving element by an input optical fiber, and converted into an electric signal. This electric signal is converted again into an optical signal by a light emitting element, and this optical signal is optically and positively fed back to the light receiving element by a partially reflecting film between the light emitting element and an output optical fiber. In this way, the input optical signal can be electrically or optically converted in a two-valued state at the output side of the light receiving element or light emitting element.
