Abstract: An exposure head includes at least one light-emitting chip and a board. The at least one light-emitting chip includes a plurality of light-emitting portions for emitting light for exposing a photosensitive member from light-emitting surfaces. The at least one light-emitting chip is supplied with power from a power source via a power line. The board is on one surface of which at least one bypass capacitor connected to the power line and a ground and the at least one light-emitting chip are mounted. In a vertical direction perpendicular to the one surface of the board, a first height as a height from the one surface of the board to the light-emitting surfaces is higher than a second height as a height from the one surface of the board to an end of the at least one bypass capacitor farthest from the one surface of the board.

Abstract: A recording system includes a transportation unit that transports a paper sheet, an ejection unit that ejects an ink, a heating unit that heats the paper sheet, a discharge unit to which the paper sheet is discharged, and a control unit. The control unit specifies an amount of ejection of the ink from the ejection unit. The control unit also controls an operation of the heating unit such that an undried region where the ink on the paper sheet is not dried and a dried region where the ink on the paper sheet is dried are formed on the paper sheet. Then, the control unit controls a transporting operation by the transportation unit such that the paper sheet on which the dried region and the undried region are formed is discharged to the discharge unit.

Abstract: A method of manufacturing a glass substrate having a penetrating structure, the method includes: (1) preparing a glass substrate that has a first surface and a second surface opposite to each other, and includes 3 mol % to 30 mol % of B2O3 in terms of oxide; (2) having the glass substrate irradiated with a laser from a first surface side, to form an initial penetrating structure; (3) wet etching the glass substrate having the initial penetrating structure formed; (4) polishing the wet-etched glass substrate from the first surface side, by using an abrasive including acid-soluble abrasive grains; and (5) cleaning the glass substrate with an acid solution.

Abstract: A post-processing device includes a processing tray, an aligning plate, a transport section, a feeding section, and a pressing section. A sheet before being subjected to stapling processing by a stapler is to be mounted on the processing tray. The aligning plate aligns ends of a plurality of sheets. The transport section transports the sheet toward the aligning plate. The feeding section is provided between the transport section and the aligning plate and feeds the sheet in a transport direction. The pressing section is provided between the transport section and the aligning plate and applies, to the sheet, a pressing force having a component in a direction opposite from the transport direction. Further, the pressing section applies the pressing force to the sheet before the feeding section applies a feeding force to the sheet.

Abstract: An object of the present invention is to provide a chemically strengthened glass having enhanced surface strength and bending strength. The present invention relates to a chemically strengthened glass having a compressive stress layer formed on a surface layer thereof by an ion exchange method, in which a straight line obtained by a linear approximation of a hydrogen concentration Y in a region of a depth X from an outermost surface of the glass satisfies a specific relational equation (I) in X=0.1 to 0.4 (?m), and an edge surface connecting main surfaces on a front side and a back side of the glass has a skewness (Rsk) measured based on JIS B0601 (2001) being ?1.3 or more.
