DEFINITION

Classification: 347/55

With applied electric field ejection (applied to fluid):

(under subclass 54) Subject matter wherein the source of intermittent energization is an electric field.

(1) Note. In this subclass the electric field is applied to the fluid*. The fluid* may contain ions or electrons. For application of an electric field to an ion or electron beam, see Class 346, subclasses 159 or 158 respectively. The simultaneous development of a modulated ion or electron beam formation is found in Class 346, subclasses 159 or 158.
