  • Patent number: 9469110
    Abstract: A liquid ejecting head includes: an ejection surface along which a plurality of nozzles that eject ink are arranged; and a projection portion which has a long shape on the ejection surface, and protrudes toward the ejection surface, in which the projection portion includes a part in which the height varies from one end side to the other end side, in which the width of the projection portion becomes narrower from a base side to a tip end side in the direction of height, and in which the shapes of end portions of the projection portions on one end side and the other end side are different from each other. Accordingly, even when a medium transported opposing the ejection surface is curled, it is possible to prevent the medium from floating up by the projection portion, and thus, it is possible to prevent the medium from coming into contact with the ejection surface by a simple configuration.

    Abstract: A system for bulk separation of single-walled tubular fullerenes (100) based on chirality is provided wherein an array of longitudinally directed channels (32) are formed on a crystalline substrate (30) to form a separation plate (300). At least one of the separation plate (300) and a solution or suspension of the single-walled tubular fullerenes (100) is displaced relative to the other for exposing at least a portion of the plurality of single-walled tubular fullerenes (100) to the channels (32). Each of the channels (32) exposes portions of the upper surface (38) of the crystalline substrate (30) and the longitudinal direction is selected to be an energetically favored “locking angle” for single-walled tubular fullerenes (100a) of one chiral angle to be adsorbed to the exposed is substrate surface (38). The adsorbed single-walled tubular fullerenes (100a) are subsequently removed from the separation plate (300).
