  • Device for generating jet with electric field
    Patent number: 4818184
    Abstract: A device for generating jets in which two electrodes are disposed in a liquid. One of the electrodes is a plane electrode and the other is disposed at a predetermined distance from the plane electrode and has a plurality of space areas. The space areas are alternately large and small. When a high voltage is applied between the two electrodes, jets are generated from the large space areas.
