    摘要： In an inkjet recording apparatus, a head unit composed of a recording head and a ink tank is mounted on a carriage with an ejection port surface facing upward. The recording head records an image on a lower surface of a medium to be recorded by ejecting ink upward from ejecting ports. A preliminary ejection receiver is disposed outside of a region where an image can be recorded on the medium to be recorded to receive ink preliminarily ejected from the recording head in order to maintain and recover an ink ejection performance of the recording head. The preliminary ejection receiver has an opening acting an inlet for the preliminarily ejected ink. Further, a ceiling surface, which inclines with respect to a horizontal direction and on which the ink preliminarily ejected into the preliminary ejection receiver deposits, is disposed above the opening. With this arrangement, ink ejected into the preliminary ejection receiver is prevented from leaking from the opening.

    摘要： A liquid ejection method includes a step of preparing a liquid ejection head including an electrothermal transducer element for generating thermal energy contributable to ejection of liquid, an ejection outlet for ejecting the liquid, the ejection outlet being provided at a position opposed to the electrothermal transducer element, and a liquid flow path in fluid communication with the ejection outlet to supply the liquid to the ejection outlet and having the electrothermal transducer element on its bottom side; and a step of applying the thermal energy to the liquid to cause the liquid to undergo a change of state and thus to create a bubble. The liquid is ejected through the ejection outlet by the pressure of the bubble. The bubble is first in communication with ambience during reduction of the volume of the bubble after the bubble reaches a maximum volume.

    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.
