    Abstract: Provided is a method for manufacturing a liquid-ejecting head whereby in die slide injection molding it is possible to stably inject resin in secondary molding without damaging the shapes of parts that were formed in primary molding. In order for that, in the connecting section in which a convex section of a cover member is inserted into an opening of a liquid-supply member, the closest distance to the opening in the area where secondary resin is injected is made larger than the gap between the opening and the convex section. As a result, the resin is prevented from flowing into a liquid path during the secondary molding.

  • Patent number: 10073341
    Abstract: In nanoimprinting processes, photo-cured products often separate from the substrate and stick to the mold due to insufficient adhesion between the photo-cured product and the substrate. This causes a defect of pattern separation. An adhesion layer composition used for forming an adhesion layer between a substrate and a photocurable composition includes a compound (A) having at least two functional groups, and a solvent (B). The functional groups include at least one functional group capable of being bound to the substrate, selected from the group consisting of hydroxy, carboxy, thiol, amino, epoxy, and (blocked) isocyanate, and at least one hydrogen donating group as a functional group capable of being bound to the photocurable composition.

  • Patent number: 10074029
    Abstract: A detecting unit detects subjects from an image photographed by a first camera and an image photographed by a second camera different from the first camera, a deciding unit decides whether a first subject photographed by the first camera and a second subject photographed by the second camera are a same subject, and a generating unit generates color correction information based on information indicating color of plural sets of the subjects decided as the same subject by the deciding unit. Thus, it is possible to reduce a difference of color between plural cameras even in the case where the photographing ranges of the plural cameras do not overlap.

  • Patent number: 10073663
    Abstract: A network device that is capable of notifying of a factor of an error when reboot in response to an instruction cannot be performed due to an operating state. The network device is connected to a network. A receiving unit receives a reboot instruction through the network. A determination unit determines propriety of reboot based on an operating state of the network device when the receiving unit receives a reboot instruction. A reply unit replies information indicating no error when the determination unit determines that reboot is available, and replies information indicating an error together with information indicating a factor of unavailable reboot when the determination unit determines that reboot is unavailable.

  • Patent number: 10074045
    Abstract: An image forming apparatus includes an image bearing member; a developing device; a supply device that supplies the developing device with toner; a density detector that detects information about a toner density serving as a ratio of toner and carrier of the developer of the developing device; and a controller that is able to execute a remaining amount determination mode which interrupts the image forming operation and performs a toner supply operation on the developing device from the supply device, based on the detection result of the density detector. The controller at least selectively executes a first state that immediately prohibits the image formation, a second state that allows the image forming operation, and a third state that executes the mode again, based on the detection result of the density detector acquired after the start of execution of the mode.

  • Patent number: 10075714
    Abstract: The value of a quantization parameter for at least one second color component of an image or image portion is determined using a current color format among several possible color formats. The determination comprises the steps of selecting at least one function associated with a possible color format, and determining the value of the quantization parameter for the second color component by applying said at least one function to a value of an intermediate quantization parameter which is based on the value of the quantization parameter of the first color component of the image or image portion. The at least one function is selected independently from the current color format.

  • Patent number: 10074039
    Abstract: An image processing apparatus includes a first obtaining unit to obtain a number of images in which a pair of a first person and a second person simultaneously appears, out of a plurality of images. A detection unit detects whether the pair appears in a target image group, which is one of a plurality of image groups into which the plurality of images is classified. In determining whether the pair appears in the target image group, it is determined that the pair appears in the target image group not only in a case when the target image group includes an image in which the first person and the second person simultaneously appear, but also, in a case when the target image group includes images in which the first person and the second person appear separately.
