Fusing nanowire inks are described that can also comprise a hydrophilic polymer binder, such as a cellulose based binder. The fusing nanowire inks can be deposited onto a substrate surface and dried to drive the fusing process. Transparent conductive films can be formed with desirable properties.

A liquid ejection device includes: a liquid ejection unit with an ejection port surface provided with an ejection port from which liquid is ejected and configured to eject the liquid onto a substrate at an ejection position; an image capturing mechanism configured to face the ejection port surface of the liquid ejection unit and to capture an image of the ejection port surface at a maintenance position different from the ejection position; and a lighting unit configured to irradiate the ejection port surface at multiple incidence angles with respect to the ejection port surface in an operation of capturing an image of the ejection port surface by the image capturing mechanism.

An application apparatus includes: an application needle that applies, to a target, an application material having its viscosity changing under shear; a drive unit that moves the application needle up and down; and a controller that controls the drive unit to move the application needle such that shear is applied to the application material at a shear speed depending on a type of the application material and depending on a target application amount or a target application diameter.

A high viscosity material is discharged in the form of a continuous thread from an application nozzle toward an end of a workpiece and a space S on the side of the workpiece so that the high viscosity material in the form of the thread adheres to a front surface of the workpiece and the high viscosity material discharged in the form of the thread into the space on the side of the workpiece pivots around an edge of the workpiece to a back surface of the workpiece and adheres to the back surface of the workpiece. The high viscosity material can thus be applied to both the front and back surfaces of the workpiece in one step of discharging the high viscosity material only from the front surface side of the workpiece.

A method includes receiving a model of the material dispenser and, at a first characterization period of a material bead dispensing operation, communicating, to the material dispenser, a first characterization flow rate input. The method also includes, at a second characterization period of the material bead dispensing operation, communicating, to the material dispenser, a second characterization flow rate input. The method also includes generating, using at least one sensor, three-dimensional data associated with a material bead corresponding to the material bead dispensing operation. The method also includes characterizing at least one parameter of the model of the material dispenser using at least the first characterization flow rate input, the second characterization flow rate input, and the three-dimensional data associated with the material bead.

A discharge apparatus includes an ink accommodating unit that accommodates a clear ink, a discharge head including a nozzle configured to discharge the clear ink to a print target, a heating unit configured to heat the print target, and a wiping member configured to wipe a nozzle-formed surface of the discharge head including the nozzle. The clear ink includes water and resin particles having a volume average particle diameter of 50 nm or less. A dried film of the clear ink has glass transition temperatures (Tg) at 50 degrees Celsius or higher and at lower than 0 degrees Celsius.

A rectifying device includes: a first flow channel member that has an annular first flow channel through which a fluid flows in an axial direction, the first flow channel being provided between an inner peripheral wall and an outer peripheral wall; a second flow channel member that has a second flow channel between the inner peripheral wall and the outer peripheral wall, the second flow channel being provided upstream of the first flow channel in a flowing direction of the fluid and being connected with the first flow channel along an entire circumference; an inflow section that is provided at the second flow channel member and that allows the fluid to flow into a circumferential area of the second flow channel located away from the first flow channel in the axial direction; a first guide wall that is provided within the second flow channel at a position located away from the inflow section in a circumferential direction and that guides the fluid flowing toward a first side in the circumferential direction through the second flow channel toward the first flow channel; and a second guide wall that is provided within the second flow channel at a position adjacent to the first guide wall in the circumferential direction, the second guide wall guiding the fluid flowing toward a second side in the circumferential direction through the second flow channel toward the first flow channel and being disposed in a direction intersecting the first guide wall.

A coating device includes: a coating liquid holding part provided with an upper opening portion and a lower opening portion and holding a coating liquid that is supplied from a coating liquid supply part; and an annular body that is disposed inside the coating liquid holding part, through which a cylindrical body penetrating the upper opening portion and the lower opening portion of the coating liquid holding part penetrates, and in which the coating liquid held by the coating liquid holding part flows in from an upper side and flows out from a lower side with a relative movement to the cylindrical body, the annular body being installed to be relatively displaceable along an installation surface intersecting a direction of the relative movement with respect to the coating liquid holding part.
