Abstract: An object of the present invention is to provide a DP receptor antagonist. A compound represented by general formula (I): (wherein all symbols are as shown in the specification) and a pharmaceutically acceptable salt thereof have DP receptor antagonistic activity and are also highly safe, and thus are useful as active ingredients of pharmaceuticals for DP receptor-mediated diseases. In addition, the compound represented by the general formula (I) and the pharmaceutically acceptable salt thereof also have good transferability to the central nervous system, and thus are particularly useful as a preventive and/or therapeutic agent for diseases associated with DP receptors present in the central nervous system among DP receptor-mediated diseases, that is, sleep-wake disorders.

Abstract: It is an objective to provide a method for controlling root parasitic plants. The present invention is directed to a method for protecting plants from root parasitic plants comprising regulating the activity of a protein associated with the strigolactone biosynthetic pathway (including the strigolactone biosynthetic and signalling pathway) in plants or expression of a gene encoding such a protein.

Abstract: An apparatus for efficiently cleaning a platen roller of a printer. A cleaning unit is attached to a main unit in place of a removal unit for an intermediate transfer sheet. A cam is turned by means of turning an arm UP/DOWN lever, and the arm is turned from an UP position to a DOWN position by means of the cam, to thus bring a cleaning pad on a leading end of the arm into contact with a platen roller and perform cleaning operation. When an operation mode is set to a cleaning mode and when attachment of the cleaning unit UC is detected, the platen roller is rotated, thereby allowing cleaning operation.

Abstract: A printer transfers to one image formation area a plurality of single colors of ink repeatedly arranged in a longitudinal direction of the ink sheet, to thus produce in an image formation area of an intermediate transfer sheet a transfer image formed as a result of lamination of single color images, and also transfers the transfer image of the intermediate transfer sheet to a subject to be printed, thereby producing a desired image on the subject. During the course of a first single color of ink C being transferred from the ink sheet to an image formation area of an intermediate transfer sheet, to thus produce a single color image in the first color on the intermediate transfer sheet, a position mark is transferred by use of a black ink area provided at a widthwise edge of an area of the first single color of ink of the ink sheet and outside the image formation area of the intermediate transfer sheet.

Abstract: An image is appropriately printed on a print target with at least a print area having a print surface and other areas connected to the print area at angles. A retention member for retaining the print target is formed from a disk tray, and an adapter removably attached to the disk tray. When an image is printed on a print target having a U-shaped cross-sectional profile, a recessed section on which the print area (an upper arm section) is to be placed is formed in an upper surface of the adapter. A lateral hole into which a lower arm—a non-print area—is to be inserted is formed in a side surface of the disk tray. In order to form a cutout space for accommodating a connection section which connects the upper arm with the lower arm, a cutout is formed in the side surface of the disk tray and in a side surface of the adapter, as well.
