Ink jet apparatus with a flexible piezoelectric member and method of operating same |
摘要 |
An ink jet comprises an elastic tubular member (14) characterized by piezoelectric properties. The tubular member (14) is terminated in an orifice (26) adapted to pass droplets of ink when the chamber formed within the tubular member (14) is reduced in size. The piezoelectric properties are provided by a substantially homogeneous mixture of piezoelectric material and an elastic binder.
