ACOUSTIC MEMORIZING UNIT Russian patent published in 1995 - IPC

FIELD: acoustic-electronic data processing units. SUBSTANCE: unit has piezoelectric acoustic line 1. Unit 2 for introducing into the acoustic line and unit 3 for outputting out piezoelectric acoustic line are disposed onto the sonic line. Unit has also irradiator which has in turn electron-ray gun 4 and collector electrode 5 disposed above working surface of piezoelectric acoustic line 1. Unit has capacitive electrode 6, constant voltage supply 7 for feeding gun 4. Source 7 is connected to electrodes of electron-ray gun 4 (to cathode 8, modulating grid 9, anode 10). Unit has additional power source 11 and pulse supply 12. EFFECT: improved store time; reduced losses at signal recording. 1 dwg
