Title: Image processing device
Inventor: YAMADA KIYOSHI
IPC: H04N1/46
Filed: 1984-08-29
Abstract: PURPOSE:To obtain image output within an extremely short period of time from image data input by transmitting image data between an I/O section consisting of an image data supply section and an image output section and image memory on extension bus. CONSTITUTION:Two bus lines, or a main bus line 1 and an extension bus line 1 are installed. This enables the transmission of image data between I/O circuits and image memory 11 to be independently controlled by the image memory 11 instead of the control of a CPU 4. The line 2 on which image data is transmitted can be independently used by separating it from the lines used by the CPU 4. Therefore, while the CPU 4 accesses to a color text input device 7 and a color printer 8, image data can be transmitted, which permits high-speed transmission of image data. In addition, because 4 groups of image data are transmitted, the transmission rate increases more.

Abstract: PROBLEM TO BE SOLVED: To reduce residual bubbles on a heating element while discharge efficiency is improved by a method wherein under a state in which an extension line of a free end part of a movable component opens a bubble generating area to a discharge opening, the free end is positioned by tilting the movable component, and the movable component is displaced in forming the bubble by taking this position as a standard. SOLUTION: A movable component 31 is provided on an element substrate 1 of a liquid channel 10 interconnected to a discharge opening 18. A free end 32 is provided to a downstream side to its fulcrum 33. The free end 32, before foaming, is slightly displaced to the liquid channel 10 side to be tilted, and an extension line of the movable component 31 is made to come directly to a discharge opening part forming area X. Then, a bubble generating area 11 exists between the heating element 2 and the movable component 31. Consequently, a load when liquid above the movable component 31 is pushed away is lightened by foaming pressure.  Further, since liquid of a volume W2 content of the bubble remaining in the bubble generating area in defoaming is fed principally from a second channel 16, high speed refilling is carried out by taking a retreat distance of a meniscus of about a half of the volume W1 above the movable component 31.
