摘要： An impulse ink jet print head and method of fabricating same. The print head comprises a plurality of superposed, contiguous plates including a nozzle plate with at least a pair of nozzles for ejecting ink droplets in a direction perpendicular to a plane of the plates. Another plate is a channel plate defining at least a pair of coplanar axially aligned elongated chambers, each connected to an ink supply and having an outlet communicating with an associated nozzle. A diaphragm plate overlies the channel plate and has transducers thereon for displacing ink in each of the chambers to eject discrete ink droplets from the nozzles. Other plates may include a manifold plate for directing ink to a plurality of pairs of chambers and a restrictor plate with restictor orifices positioned between the manifold plate and each of the chambers. The method of fabricating the print head includes forming the different plates, forming the transducers, and assembling all of the components in a particular relationship.

摘要： High frequency of droplet ejection with minimized crosstalk and a uniform large ink droplet weight are realized in an inkjet printer printhead which employs two ink feed channels to couple an ink firing chamber to the source of ink. A first one of the ink feed channels has a lower fluid resistance to ink flowing in the channel than a second one of the ink feed channels. The first ink feed channel and the second ink feed channel each have an inlet to the ink source and are arranged such that the inlet of the first ink feed channel is closer to the ink firing chamber than the inlet of the second ink feed channel. Furthermore, adjacent ink firing chambers are arranged such that a lower fluid resistance ink channel of one ink firing chamber is next to a higher fluid resistance ink channel of a neighboring ink firing chamber. Nozzle diameter, heater resistor, and firing chamber dimensions are also optimized for the printhead.

摘要： An improved drop-on-demand ink jet print head is formed of a plurality of superposed metal plates that are diffusion bonded into a unit. A plurality of superposed metal plates are diffusion bonded into a unit. Punched and/or etched holes form ink passages that include manifolds that supply ink chambers through restrictors and exit orifices that supply ink to nozzles for ejection as droplets. Crosstalk among nozzles is minimized by the use of a compliant manifold plate and a relief slot in an adjacent nozzle plate so as to be coextensive with its associated manifold. The restrictors and the nozzles are substantially equal in diameter and length. The print head produces droplets up to 80 micrometers in diameter at frequencies up to 7 KHz with little variation in droplet size and velocity as a function of frequency.
