    摘要: A liquid discharging method of regulating and directing an air bubble to a discharge port by a substrate having a heat generating surface for generating heat for creating an air bubble in a liquid disposed in face-to-face relationship with a liquid discharge port, a movable member provided so as to intervene between the heat generating surface and the discharge port, and having a free end displaceable by the air bubble, the free end or a changing portion being located in an area opposed to the minimum area region of the discharge port or upstream of the opposed area, and an opposed surface opposed to a surface which provides the heat generating surface side of the movable member when the free end of the movable member is displaced by the air bubble, and fixed to cooperate with the movable member during the displacement of the movable member to direct the air bubble toward the discharge port.

    摘要: A method of recording (preserving) and reproducing an image is disclosed. The x and y axes are assumed on the plane of an original image, the z axis (density axis) is assumed to be perpendicular to the x and y axes, and a space defined by the x, y, and z axes is divided into rectangular solid cells. The volume ratio below a density distribution curved surface of the volume of each rectangular solid is recorded. Upon reproduction, the curved surface is reproduced based on the volume ratios of the rectangular solids which the density distribution curved surface crosses, and those of rectangular solids adjacent thereto.In a four-dimensional Euclidean space defined by an image plane (x,y), a density or brightness D, and time or a frame f, an image is expressed by a solid in this space. This space is divided into four-dimensional rectangular solids, and an amount proportional to the volume of the solid in each rectangular solid is recorded or transmitted. Upon reproduction, the solid is reproduced based on the volume amounts of the rectangular solids and those of rectangular solids adjacent thereto, thereby reproducing a dynamic image.
