Abstract: A roller unit aligns tapes in a width direction and feeds the tapes in a length direction while pressing the tapes in a thickness direction. The tapes are made of fibers which have not been impregnated with resin or have been impregnated with the resin. The roller unit includes rollers and a support shaft. The rollers rotate by friction force between the tapes and the rollers. The rollers are aligned so that rotation axes lie on a same straight line. Maximum diameters of the rollers are same as each other. The support shaft supports the rollers rotatably at rotational speeds independent from each other. Each of the rollers includes springs and thereby has elasticity. Length directions of the springs as well as expansion and contraction directions of the springs are radial directions of the each of the rollers. The springs are radially disposed inside the each of the rollers.

Abstract: A liquid ejection apparatus includes a liquid ejection head configured to eject liquid from a plurality of nozzles to a medium and a plurality of caps configured to cover a plurality of nozzle groups. The plurality of caps includes a first cap group covering a first nozzle group positioned near the center of the liquid ejection head among the plurality of nozzle groups and a second cap group and a third cap group provided at positions sandwiching the first cap group in the width direction. The liquid ejection head is configured to execute a first idle ejection for ejecting liquid from the plurality of nozzles constituting the plurality of nozzle groups to the plurality of caps and a second idle ejection for ejecting the liquid from the plurality of nozzles constituting the second nozzle group and the third nozzle group to the second cap group and the third cap group.

Abstract: A server apparatus includes a receiving section that receives first apparatus information and associated information in association with each other, a storage section that stores second apparatus information and user information in association with each other, a control section that determines an execution condition based on the associated information received by the receiving section, and a transmitting section that transmits, to a printing apparatus, the execution condition determined by the control section. The control section causes the execution condition thus determined and the user information associated with the second apparatus information that matches the first apparatus information to be stored in the storage section in association with each other. The transmitting section transmits, to the printing apparatus having the first apparatus information that matches the second apparatus information associated with the user information, the execution condition associated with the user information.

Abstract: A combined substrate includes a first substrate having multiple first metal posts, a second substrate having multiple second metal posts such that the second metal posts are positioned to oppose the first metal posts, respectively, and multiple solder structures interposed between the first metal posts and the second metal posts, respectively. The first metal posts and/or the second metal posts have recessed surfaces formed such that the solder structures are formed on the recessed surfaces, respectively.

Abstract: A printed wiring board includes a first circuit substrate having first pads and second pads such that the first pads are positioned to mount an electronic component on the first circuit substrate and that the second pads are positioned to electrically connect the first circuit substrate to a second circuit substrate, and metal posts including plating material and formed on the second pads respectively such that the metal posts are positioned to mount the second circuit substrate on the first circuit substrate. Each of the metal posts has a height h1 and a thickness b such that the metal posts have a value h1/b which is greater than 0.1 and smaller than 1.0 where the value h1/b is obtained by dividing the height h1 by the thickness b.
