Abstract:
Disclosed is an ultraviolet absorber water-dispersed composition, comprising the following components (A) and (B); (A) a benzotriazole-type ultraviolet absorber represented by general formula (1 ) below wherein R1 and R2 denote alkyl groups having a carbon number from 1 to 18, may be identical or different, and may be substituted by one or two or more groups selected from the group consisting of alkyl groups having a carbon number from 1 to 4, and cycloalkyl groups and aryl groups both having a carbon number from 5 to 12; and (B) polyglycerol monoalkyl ester with a mean degree of polymerization of glycerol of 5 or more. The water-dispersed composition is capable of stably maintaining the dispersed state of benzotriazole-type ultraviolet absorbers even in the presence of salt.
Abstract:
A post-processing device (200) includes a circulation conveyance path, a zeroth conveyer (R0), and a controller (50). The circulation conveyance path includes a first conveyance path (W1), a second conveyance path (W2), a third conveyance path (W3), a first conveyer (R1), a second conveyer (R2), and a third conveyer (R3). The first and second conveyers convey a preceding sheet (P1) along the first and second conveyance paths. The third conveyer conveys it from the third conveyance path to the first conveyance path. The zeroth conveyer conveys a following sheet (P2) toward the first conveyer. The controller controls the third conveyer to stop the preceding sheet, subsequently controls the zeroth conveyer and the third conveyer to overlay the preceding sheet with the following sheet to form a sheet bundle (Q) having a shift amount (G) between a leading edges of the preceding sheet and the following sheet and strike the leading edges of the preceding sheet and the following sheet against the first conveyer.

Abstract:
An imprint apparatus molds and cures an imprint material on a substrate using a mold to thereby form a pattern on the substrate. The apparatus includes a first drive mechanism (18) configured to apply a force in a planar direction of the mold (7) and change the planar shape of the pattern portion formed in the mold (7), and a second drive mechanism (33a-33d) configured to deform the mold (7) about an axis (for example, the Y axis) that is orthogonal to the pressing direction of the mold (7) and the uncured resin (for example, the Z axis) and a direction of the force applied by the first drive mechanism (18) (for example, the X axis).
