摘要： A flow path formation substrate to which a nozzle plate is mounted includes a pressure chamber per nozzle, an individual supply path leading to the pressure chamber, an individual recovery path communicating with a flow channel near the nozzle. A conduction unit electrically coupled through a lead electrode to a pressure generator causing a pressure of the pressure chamber to vary is located at a position where the conduction unit overlaps with a flow path area of at least one individual flow path of the individual supply path or the individual recovery path in a plan view from a lamination direction in which the nozzle plate and the flow path formation substrate are laminated.

摘要： A fluid discharging apparatus includes an accommodation unit that accommodates a fluid, a discharge port that communicates with the accommodation unit, a moving object that moves in a first direction toward the discharge port and in a second direction away from the discharge port in the accommodation unit, and a control unit that controls driving of the moving object. The control unit performs discharging processing and moving processing. In the discharging processing, the discharge port is opened by moving the moving object from a closed position at which the discharge port is closed, in the second direction, and then the fluid is extruded and discharged from the discharge port by moving the moving object in the first direction. In the moving processing, the moving object is moved in the second direction during a period when the fluid is discharged from the discharge port in the discharging processing.

摘要： A liquid discharge apparatus includes a liquid chamber communicating with a nozzle that discharges liquid; a capacity changer that changes a capacity of the chamber; an inflow path connected to the chamber allowing the liquid to enter the chamber; an outflow path connected to the liquid chamber allowing the liquid to exit the chamber; a first resistance changer changing a flow resistance of the inflow path; a second resistance changer changing a flow resistance of the outflow path; and a controller controlling the capacity changer, the first resistance changer, and the second resistance changer. The controller allows the nozzle to discharge the liquid by increasing the flow resistance of the inflow and outflow paths, increasing the capacity of the chamber, and then, while the flow resistance of the inflow and outflow paths remain increased, decreasing the capacity of the chamber.

摘要： A three-dimensional modeling apparatus includes an ejection portion capable of ejecting a fluid material, which is a material of an object, and a control portion that forms a laminated body in which one layer or more of cross-section bodies are laminated by executing one or more repetitions of a cross-section body formation process, which forms a cross-section body equivalent to one layer of the object by controlling the ejection portion and ejecting the fluid material. The control portion executes a correction process that ejects the fluid material onto a target correction location, which is at least a portion of an outline section of an upper surface of the laminated body.

摘要： A liquid ejecting apparatus includes a liquid chamber in communication with a nozzle, a volume changing unit configured to change a volume of the liquid chamber, an inflow passage through which the liquid flows into the liquid chamber, an outflow passage through which the liquid flows out of the liquid chamber, a passage resistance changing unit configured to change a passage resistance of the outflow passage, and a controller configured to control the volume changing unit to reduce the volume of the liquid chamber so as to cause the liquid to be ejected through the nozzle. In filling the liquid chamber with the liquid for ejection of the liquid through the nozzle, the controller controls the passage resistance changing unit to change the passage resistance of the outflow passage to an increased passage resistance and controls the volume changing unit to increase the volume of the liquid chamber.

摘要： A liquid ejecting apparatus is provided with a liquid chamber which communicates with a nozzle for ejecting liquid; an inflow path which is connected to the liquid chamber; a liquid supply unit which supplies the liquid to the inflow path; an outflow path which is connected to the liquid chamber, and through which the liquid is caused to flow out from the liquid chamber; a moving object which causes the liquid to be ejected from the nozzle by reciprocating toward the nozzle in the liquid chamber; and an actuator which causes the moving object to reciprocate. In an ejecting state in which liquid is continuously ejected from the nozzle due to at least reciprocating of the moving object, a flow path resistance of the outflow path is larger than that of the inflow path.

摘要： A fluid discharging apparatus includes a storage chamber storing a fluid, a discharge port communicating with the storage chamber, a supply unit supplying the fluid to the storage chamber by pressure, a moving object moving in a first direction toward the discharge port and in a second direction away from the discharge port, a pressure changing mechanism, and a control unit controlling the moving object and the pressure changing mechanism. The control unit performs discharge processing, moving processing, and pressure control processing. In the discharge processing, the moving object moves from a closed position closing the discharge port in the first direction to discharge the fluid. In the moving processing, the moving object moves in the second direction while the fluid is discharged from the discharge port. In the pressure control processing, the pressure changing mechanism suppresses a pressure increase in storage chamber.
