Publication number: 20080211874Abstract: A fluid ejector head, including a fluid ejector disposed on an ejector support, and a semiconductive junction photo sensor electrically coupled to the fluid ejector. The fluid ejector head also includes a photon source photonically coupled only to the semiconductive junction photo sensor. Photons emitted from the photon source interact with the semiconductive junction photo sensor and generate an activation signal. The activation signal in turn activates the fluid ejector ejecting a fluid away from the fluid ejector.Type: ApplicationFiled: May 5, 2008Publication date: September 4, 2008Inventors: Antonio S.

Patent number: 4695854Abstract: An impulse ink jet print head of the type including a plurality of operating plates held together in a contiguous superposed relationship. A plurality of piezoceramic transducers are mounted on a diaphragm such that each transducer overlies one of a similar plurality of ink chambers. The transducers are electrically energized and thereby caused to displace ink in the chambers resulting in the ejection of ink droplets through a plurality of nozzles, one nozzle being in fluidic communication with each of said chambers. An IC driver may be interfaced between an external control computer and the transducers to simplify the external circuitry necessary for operation of the print head. Ink is delivered to the chambers through compliant manifolds mounted externally of the print head, then through restrictor orifices formed in the same plate in which the nozzles are located. The construction allows for venting of the manifolds.Type: GrantFiled: July 30, 1986Date of Patent: September 22, 1987Assignee: Pitney Bowes Inc.Inventor: Antonio S. Cruz-Uribe
