Abstract: Provided is a novel inkjet printer system that can use machine learning to improve the inspection performance of a printing inspection device. The inkjet printer system includes, in the machine learning, a random test printing function unit (301) that has a function that prints a random dot arrangement that is based on various characters printed in the printing area of a printing target, and an evaluation function training function unit (302) that has a function that optimizes an evaluation function for inspecting a printed image on the basis of a captured image of the results of the printing.

Abstract: A joined article including: a resin (1) having a linear expansion coefficient at 30° C. to 200° C. of 17 ppm/° C. or higher and a thickness of 5 to 100 ?m; and a metal joined to a surface of the resin (1) and having a thickness of 5 to 50 ?m. The resin (1) includes a heat-affected layer that is close to the metal and that occupies 80% or less of the thickness of the resin (1), and the joined article is a dielectric material for a substrate. Also disclosed is a substrate including the joined article and a resin (2) stacked on the joined article.

Abstract: A chair (1) includes an installation base (10), a leg column (11) supported by the installation base (10) in a tiltable manner, a seat body (12) supported on an upper part of the leg column (11), an elastic member (19) which urges the leg column (11) to an initial tilted posture, and a coming-off restriction member (22) which restricts coming-off of the leg column (11) from the installation base (10). On a support wall (16) of the installation base (10) having an insertion hole (20) through which part of the coming-off restriction member (22) is inserted, a slide guide (21) coming into slidable contact with a slide guide (21) at a peripheral edge portion of a lower surface side of the insertion hole (20) is provided. The coming-off restriction member (22) has an upwardly protruding spherical guide surface (23) which is slidably brought into contact with the slide guide (21) below the insertion hole (20).
