A folded back portion flattening device includes a gripper and a presser. The gripper grips a sheet bundle formed into a booklet with the folded back portion protruding from the gripper. The presser presses the folded back portion of the sheet bundle gripped by the gripper, and includes pressing rollers which have pressing rotational surfaces and which are disposed along the folded back portion. The pressing rotational surfaces press the folded back portion. The pressing rollers are disposed so that the rotational pressing surface of a second pressing roller, which presses the folded back portion after the rotational pressing surface of a first pressing roller has pressed the folded back portion, presses deeper into an edge of the sheet bundle than the rotational pressing surface of the first pressing roller. At least one of the gripper and presser is movable in a direction parallel to the folded back portion.

A sheet processing device includes a pair of gripping rollers which can grip and convey a sheet bundle in a booklet-like form, a pressing roller which presses and flattens the folded back portion of the sheet bundle gripped by the gripping rollers, and a control unit which performs rotation control on the pair of gripping rollers. The control unit controls the gripping rollers so as to stop when the folded back portion of the sheet bundle protrudes from the rollers by a predetermined amount. The pressing roller flattens down the protruding folded back portion when the gripping rollers are stopped by the control unit and is in the state of gripping the sheet bundle.

A folded back portion flattening device includes a gripper and a presser. The gripper grips a sheet bundle formed into a booklet with the folded back portion protruding from the gripper. The presser presses the folded back portion of the sheet bundle gripped by the gripper, and includes pressing rollers which have pressing rotational surfaces and which are disposed along the folded back portion. The pressing rotational surfaces press the folded back portion. The pressing rollers are disposed so that the rotational pressing surface of a second pressing roller, which presses the folded back portion after the rotational pressing surface of a first pressing roller has pressed the folded back portion, presses deeper into an edge of the sheet bundle than the rotational pressing surface of the first pressing roller. At least one of the gripper and presser is movable in a direction parallel to the folded back portion.

A sheet processing apparatus including a folding unit, a crease processing unit, and a holding portion. The folding unit is configured to fold a sheet bundle, the crease processing unit forms a crease on a folded part of the sheet bundle, and the holding portion holds the sheet bundle between the folding unit and the crease processing unit as the crease processing unit forms the crease on the folded part.

First, an ionic liquid is placed on a glass slide, which is then installed in an evaporation apparatus, and a metal (for example, indium) is mounted as a target material at a position facing the ionic liquid, followed by sputter deposition of the metal. After sputtering, the ionic liquid containing nanoparticles dispersed therein is recovered. The nanoparticles are solid nanoparticles. Next, the ionic liquid containing the solid nanoparticles dispersed therein is placed in a test tube and then oxidized by heating in air at 250° C. for 1 hour. As a result, hollow nanoparticles having cavities formed in core portions of the solid nanoparticles are produced.
