Abstract: A liquid discharge head includes a nozzle substrate and a cover member. The nozzle substrate includes a liquid discharge surface, a plurality of nozzles, and a continuous recess. The plurality of nozzles is arranged in a nozzle arrangement area on the liquid discharge surface and configured to discharge liquid from the liquid discharge surface. The continuous recess surrounds the nozzle arrangement area on the liquid discharge surface. The cover member is joined to the nozzle substrate with the nozzle arrangement area being exposed. The nozzle arrangement area has a liquid repellency with respect to the liquid. An inside of the recess is lyophilic to the liquid and is provided with an adhesive, and the nozzle substrate is joined to the cover member with the adhesive.

Abstract: A metal member includes a first layer and a second layer. The second layer has an average crystal grain size different from an average crystal grain size of the first layer. An intermediate layer having an average crystal grain size smaller than the average crystal grain sizes of the first layer and the second layer is interposed between the first layer and the second layer.

Abstract: A molded product assembly includes a molded product being mountable to a body to be mounted having a mounting hole via a fastener. The molded product has a post projecting toward the mounting hole and disposed on a back surface of the molded product, at least a part of the post projecting through the mounting hole to a back surface side of the body to be mounted in mounting the molded product to the body to be mounted, and a holding portion disposed on the part of the post to hold the fastener. The fastener has a portion to be held that is held by the holding portion, and an elastic engagement leg being elastically deformable and having an engagement portion to be engaged with a peripheral edge of the mounting hole, the elastic engagement leg being located on the back surface side of the body to be mounted.

Abstract: In a long trim member for vehicle, a first side wall of an attachment portion is formed with an elastic holding lip and an elastic sealing lip. A second side wall of the attachment portion is formed with an engagement portion and a projection ridge having a slide guide surface. When the attachment portion is pushed, a tip of the elastic sealing lip is kept not in contact with a bottom wall, a projection end of a projected flange portion is slid on the slide guide surface while the elastic holding lip is deformed elastically until the projection end of the projected flange portion passes the peak of the projection ridge. When the attachment portion is pushed further, the elastic sealing lip is deformed elastically in the direction opposite to the pushing direction and the engagement portion of the second side wall is engaged with a lock portion of the flange.
