  • Publication number: 20220339929
    Abstract: A liquid ejection head has a nozzle. A controller is configured to: control the liquid ejection head to perform inspection driving, the inspection driving being driving the liquid ejection head to eject liquid from the nozzle for determining whether the nozzle is an abnormal nozzle having an abnormality in ejection of liquid; acquire a determination signal outputted from the signal output device, the determination signal indicating whether the nozzle is the abnormal nozzle; acquire a non-driving signal outputted from the signal output device when the inspection driving is not performed by the liquid ejection head; generate a differential signal by superposing the determination signal and the non-driving signal, the differential signal being a signal indicating a difference between a value of the determination signal and a value of the non-driving signal at each timing; and determine whether the nozzle is the abnormal nozzle based on the differential signal.

  • Patent number: 9744749
    Abstract: A plastic container including a container body (1) made from a colored olefin resin and a decorative layer (3) laminated on the outer surface thereof. The decorative layer includes a transparent adhesive resin layer (3b), a transparent polyester resin layer (3a) which is the outer surface layer, and an intermediate gradation layer (3c) including a portion of which the thickness gradually varies in the direction of height of the container. The gradation layer is formed of a transparent polyester resin blended with a coloring agent. The thickness of the container body varies in response to a change in the thickness of the gradation layer in a manner such that the thickness of the container body portion which is the total thickness of the thickness of the container body and the thickness of the decorative layer is not varied by the presence of the gradation layer.

  • Patent number: 9713528
    Abstract: An intraocular lens insertion device having a configuration in such a manner that, with the displacement of a haptic toward the convex side of an optical portion, which can be deformed in a curved shape, restricted by an engaging part provided to the tip part of a plunger, the haptic is deformed in a curved shape in the direction in which the haptic approaches the optical portion. The configuration allows, when the intraocular lens is pushed out by the plunger, the haptic to enter a gap formed on the concave side of the optical portion which has been deformed in a curved shape.
