<p>A piezoelectric ceramic ink-jet print head is made by an ultrasonic bonding process. Several improved features of ink jet print heads include a more cost-effective bonding process using an ultrasonic bonding technique, an improved piezoelectric ceramic structural element pattern, and improved print head piezoelectric electrical contacts. There is also disclosed an ultrasonic bonding process for joining metallic objects.</p> |
