摘要： A fluid ejection device includes a substrate; a plurality of resistors on the substrate with separation of between 4 and 8 microns between adjacent resistors; an adhesion layer applied over the plurality of resistors; and a layer of silicon carbide (SiC) applied directly over the adhesion layer such that the silicon carbide is between adjacent resistors. A method of forming a fluid ejection device includes forming resistors and conductive traces attached to a substrate; depositing an adhesion layer over the resistors; depositing a silicon carbide (SiC) coating directly over the adhesion layer; and forming an epoxy layer over silicon carbide layer.

摘要： The purpose of the present invention is to minimize the degradation of ink ejection performance by providing a circulation flow path and to effectively discharge air bubbles and the like near a nozzle without applying a load to a device. This inkjet head (1) is characterized in that: the inkjet head (1) is provided with a plurality of nozzles (211) for ejecting ink, a pressure chamber (231) individually communicated with the nozzles (211) and filled with ink, a pressure-generating means (piezoelectric element 24) as a driving source for discharging ink by applying pressure to the pressure chamber (231), an inlet (232) supplying ink to the pressure chamber (231) and having a constricted portion in which the flow path is narrower than the pressure chamber (231), and a circulation flow path (213) capable of discharging ink in the pressure chamber (231) from the vicinity of the nozzles (211); the viscosity resistance of the circulation flow path (213) is lower than the viscosity resistance of the nozzles (211); and the impedance of the circulation flow path (213) is at least half the impedance of the inlet (232).

摘要： Various configurations of print head die are described. In an example, a first print head die has first print structures disposed along a major dimension thereof perpendicular to the media path, the first print structures including a leading print structure with respect to the media path. A second print head die independent of the first print head die has second print structures disposed along a major dimension thereof perpendicular to the media path, the second print head die being staggered with respect to the first print head die along the media path, the second print structures including a leading print structure with respect to the media path. A portion of the second print structures overlap a portion of the first print structures by an extent between a minimum value and a linear function of a separation between the respective leading print structures of the first and second print head dies.

摘要： A liquid ejecting head includes a flow path portion that has a first communication path, a case member that has a second communication path, a seal member that is pinched between the case member and the flow path portion, and a cover member to which a head chip that discharges the liquid from a nozzle communicating with the second communication path is set. An opening that has a predetermined space formed inside is formed on a recording medium side of the case member. The cover member covers the opening in a state where the head chip is arranged in the predetermined space and the nozzle is exposed to an outside. The seal member allows the first communication path and the second communication path to be connected in a liquid-tight manner and seals the predetermined space on a case member side.

摘要： A microfluidic device (10) includes first and second glass substrates (12, 42) bonded together. The first glass substrate (12) has first and second opposed surfaces (14, 16). A die pocket (18) is formed in the first opposed surface (14), and a through slot (22) extends from the die pocket (18) to the second opposed surface (16). The second glass substrate (42) is bonded to the second opposed surface (16) of the first glass substrate (12) whereby an outlet (O2) of a channel (48) formed in the second glass substrate (42) substantially aligns with the through slot (22). The channel (48) of the second glass substrate (42) has an inlet (I2) that is larger than the outlet (O2).
