Abstract: A printing method for printing a first image and a second image on a printing object by using a print head while changing a relative position and a relative attitude of the print head relative to the print object, includes a first printing step of printing the first image on the printing object by using the print head; a processing step of performing an expansion and contraction processing on the second image so as to adjoin the first image printed on the printing object; and a second printing step of printing the second image that has been subjected to the expansion and contraction processing so as to adjoin the first image, on the printing object by using the print head.

Abstract: A printing method for printing a first image and a second image while changing a relative position and a relative attitude of a print head relative to a printing object, includes a first printing step of printing a first print image obtained by forming an unprinted region in the first image, a detecting step of detecting the unprinted region, an adjusting step of adjusting the print head such that the second image adjoins the first image, and a second printing step of printing a second print image including the second image and a partial image.

Abstract: A sewing mechanism is provided with: a post bed and sewing needles, wherein an article to be sewn is interposed between the post bed and the sewing needles. When the post bed comes closer to the article to be sewn than that in the previous sewing by at least a predetermined distance, in other words, when a separation distance between the article to be sewn and the post bed becomes less than that in the previous sewing by at least a predetermined distance, a thread pulling mechanism pulls threads hooked in needle holes of the sewing needles in a direction away from the post bed.

Abstract: To provide a coating device which can precisely adjust a discharge amount of high-viscosity material. The coating device coats a high-viscosity material onto a workpiece, and includes a coating gun (2) which discharges the high-viscosity material having flowed in from an inlet port (211) from a discharge port (251); a supply mechanism which pushes out the high-viscosity material to supply from an injection nozzle; and a supply tube which connects the inlet port (211) and supply port. The coating gun (2) includes, at a gun flow channel (3a) from the inlet port (211) until the discharge port (251), a gear pump (31) and needle valve (26) as a discharge amount adjustment mechanism which adjusts the discharge amount of the high-viscosity material from the discharge port (251).

Abstract: There is provided a manufacturing method for a composite structure that makes it possible to join a thermoplastic resin molding, which serves as a second member for reinforcement, while at the same time preventing the deformation of a first member to be reinforced. The second member contains magnetic substances in a portion thereof that is to be abutted on the first member. The second member is introduced into an induction heating unit and subjected to induction heating, thereby heating the abutting portion of the second member to join the second member to the first member.

Abstract: A composite structural member made of a plate and a thermoplastic resin reinforcing member is manufactured by: continuously supplying the reinforcing member; cutting the reinforcing member; heating the reinforcing member; and pressing the heated reinforcing member to the plate.

Abstract: A mold for in-mold coating is provided that can ensure a space through which a coating material for performing in-mold coating flows. The mold for in-mold coating includes an undercut-shaped recess 15 formed of a wall portion 15a provided in a mold opening direction and an inclined wall portion 15b provided to face the wall portion 15a at a predetermined angle ?2 in a region corresponding to an end or a corner portion of a product.
