Abstract: There is provided an initial filling method for a functional liquid droplet ejection head in which a filling liquid consisting essentially of a functional liquid or a solvent thereof is initially filled in a passage of a functional liquid drop-let-ejection-head for ejecting a functional liquid droplet on a workpiece. The method includes: a sealing step of sealing a functional liquid introducing port of the functional liquid droplet ejection head communicating with the passage of the head; an immersing step of immersing a head main body of the functional liquid droplet ejection head in the filling liquid stored in a sealed vessel; a pressure-reducing step of reducing pressure inside the sealed vessel to a predetermined degree of vacuum by exhausting the atmosphere inside the sealed vessel; and a pressure-restoring step of restoring the pressure inside the sealed vessel after the pressure-reducing step.

Abstract: An inspection apparatus includes an inspection body that has a non-conductive substrate, a droplet receiving portion for receiving a droplet that is provided on the substrate, and a plurality of electrodes that are exposed on an inner surface portion of the droplet receiving portion. The droplet receiving portion has a size that corresponds to a droplet size in a state when a discharged droplet impacts normally. The inspection apparatus also includes a detector that is connected to the electrodes of the inspection body and detects a conductivity in the droplet receiving portion. The inspection apparatus makes it possible to inspect easily and in a short time period the discharge performance of a droplet discharge head of a droplet discharge apparatus. A droplet discharge inspection method is also provided.

Abstract: A wiping unit is provided that wipes a droplet discharge head included in a droplet discharge unit and reduces the likelihood or prevents a cleaner to be sprayed to a wiping sheet from getting dispersed and adhering to peripheral units. A wiping unit included in a droplet discharge unit is provided with a charged electrode, an absorption electrode, and a static elimination brush. A cleaner sprayed by a cleaner spray head is electrically charged by the charged electrode. The charged cleaner is absorbed toward the absorption electrode, and adheres to a wiping sheet that is placed just before the absorption electrode. Accordingly, it is possible to reduce the likelihood or prevent the cleaner from getting dispersed and adhering to peripheral units.

Abstract: A heating furnace includes a housing chamber adapted to house a heating object, a heater for heating the heating object housed in the housing chamber, a vacuum pump for reducing a pressure inside the housing chamber, a pressure detector for detecting the pressure inside the housing chamber; a leakage detector for detecting any leak current that is caused by reducing the pressure inside the housing chamber while power is supplied to the heater; and a controller for switching the power to the heater on or off on the basis of detection results from the pressure detector and the leakage detector.
