摘要： A fluid ejection cartridge having a cartridge body with a cavity therein and an ejection head attached to an external surface of the cartridge body opposite the cavity. A cylindrical or a rectangular-prism shaped body made of a hydrophilic open-cell foam material is disposed in the cavity of the cartridge body. The cylindrical or rectangular-prism shaped body has at least one uncoated hydrophilic surface and two or more surfaces coated with a hydrophobic material.

摘要： A method for delivering a predetermined amount of fluid from a fluid ejection head. The method includes measuring one or more parameters selected from fluid flow parameters and electrical parameters for the fluid ejection head to provide one or more measured parameters; calculating a fluid ejection offset value from the one or more measured parameters; storing the fluid ejection offset value in a memory location on the fluid ejection head; accessing the fluid ejection offset value by an ejection head controller; and adjusting an amount of fluid ejected from the fluid ejection head during a fluid ejection step using the fluid ejection offset value to provide the predetermined amount of fluid from the fluid ejection head.

摘要： A pharmaceutical drug delivery device and method of preventing drying out and drooling of an ejection head for the drug delivery device. The device includes a device body; a fluid outlet nozzle attached to the device body; and a fluid jet ejection cartridge containing a liquid pharmaceutical drug disposed in the body. A fluid ejection head is attached to the fluid jet ejection cartridge and is in fluid flow communication with the fluid outlet nozzle. An elongate, serpentine air flow path disposed between an inner surface of the fluid outlet nozzle and a sealing material that is disposed between an outer surface of the fluid jet ejection cartridge and the inner surface of the fluid outlet nozzle, wherein the elongate, serpentine air flow path provides a reduced pressure differential adjacent to a surface of the ejection head upon use of the drug delivery device and provides a humidification zone.

摘要： A backlight device comprises a plurality of point light sources, a luminance uniformity sheet, a light diffusion sheet, a plurality of lenses, and a partition wall. The luminance uniformity sheet includes transmission portions that are arranged opposite the point light sources. The light diffusion sheet is disposed on an opposite side of the luminance uniformity sheet relative to the point light sources. The lenses are disposed between the light diffusion sheet and the luminance uniformity sheet. The partition wall is disposed at least one of between the point light sources and the luminance uniformity sheet and between the luminance uniformity sheet and the lenses and is disposed between adjacent point light sources in a plan view or between adjacent lenses in the plan view.

摘要： A vibrating element includes a movable part, a substrate made of metal, a driving source, and a holding member holding the substrate. The substrate includes a pair of support beam parts, a support part, and a torsion beam part. Each of the support beam parts has a first end part and a second end part. The support part supports the first end part. The torsion beam part swingably supports the movable part. The second end part of each of the support beam parts is provided with a fixing part fixed to the holding member. By adjusting an inclination with respect to the holding member, the fixing part is fixed to the holding member in a state in which each of the support beam parts applies tension to the torsion beam part in a direction away from the movable part in a first direction in which the torsion beam part extends.

摘要： Provided is a vibrating mirror element including: a mirror part; a substrate made of metal, including a pair of beams, a support supporting each of the pair of beams, and a torsion part swingably supporting the mirror part; a driving source generating a plate wave that swings the mirror part; and a vibration suppression part suppressing vibration transmitted to the pair of beams. The vibration suppression part is configured to suppress the vibration transmitted to the pair of beams by abutting against the pair of beams at a position between a second mirror end among ends of the mirror part that is opposite a first mirror end near the support and the torsion part in a first direction in which the pair of beams extends.

摘要： A nozzle plate of a fluid ejection head for a fluid ejection device, a fluid ejection head containing the nozzle plate, and a method for making the fluid ejection head containing the nozzle plate. The nozzle plate includes at least two arrays of nozzle holes on opposing sides of a fluid supply via etched in an ejection head substrate and a photoresist layer attached to an exposed surface of the nozzle plate spanning a section of the nozzle plate between the at least two arrays of nozzle holes. The photoresist layer increases a thickness of the nozzle plate between the at least two arrays of nozzle holes to greater than 25 microns up to about 100 microns.
