摘要： Flushing regions for receiving ink droplets to be ejected when flushing signal is supplied to a recording head are provided in both of non-print regions situated at both sides of print region in order to prevent throughput during the flushing operation from deteriorating. A guide member having a slant surface is disposed between the recording head and an ink absorbing member to which the ink landed on the slant surface flows in order to reduce in size of the ink absorbing member. A porous sheet member closely faced to nozzle orifices of the recording head for receiving the ink droplets ejected therefrom is provided in order to prevent undesired mist of fine ink droplets from generating. A plurality of plate members closely faced to the nozzle orifices are provided at a predetermined angle with respect to the flight direction of the ink droplets in order to prevent the undesired mist from generating. The flushing operation is performed so as to prevent solidification of the ejected ink.

摘要： A SIMD processor includes plural processor elements (PEs) each having a processing unit for data processing, a register for holding data to be processed or already processed by the processing unit, a data transfer bus interconnecting with other PEs, and a register controller for inputting a read or write signal to the register. Read and write processing steps in the processor are carried out by the register controller in response to the signals which are sent form the register controller and inputted into a register of specific processor elements responding to an addressing signal from an external interface. The processor is capable of transferring data directly to a specific processor element, thereby achieving higher speeds of data transfer and resultant data processing and makes flexible use of registers to thereby attain efficient data processing utilizing arbitrary combinations of the register depending on bit width of the data.

摘要： The ink jet recording apparatus comprises an ink end detector for detecting when ink in each of the cartridges mounted on the carriage is exhausted, and a cover detector for detecting whether the cover member attached to the casing body of the apparatus is open. And when the ink end detector detects that the ink has been exhausted and the cover detector detects that the cover member is open, a carriage driver is driven and moves the carriage and positioned it at an opening formed in the casing body for the exchange of ink cartridges. Therefore, the operability for the exchange of ink cartridges when the ink has been exhausted can be improved.

摘要： Disclosed is a pigment dispersion that can be used for an ink jet printing-use pigment ink that affords stable printing characteristics and has excellent storage stability in an ink jet printer having a head driven at a high frequency and having finer nozzles in order to enhance image quality and raise the speed. Disclosed is also a method for manufacturing this pigment dispersion. This manufacturing method includes a step of surface-treating a self-dispersing type of pigment, in which at least hydrophilic, dispersibility-imparting group is introduced to the pigment surface directly and/or via a polyvalent group, and a step of dispersing the self-dispersing pigment obtained in said surface-treating step in an aqueous medium, wherein the dispersion step is a step in which at least the self-dispersing pigment, a wetting agent, and water are dispersed in the form of a liquid mixture.

摘要： Generally speaking, in accordance with the invention, an ink cartridge for an ink-jet recording apparatus can include a container formed by a plurality of walls, an ink supply port extending through at least one of said walls of the container to permit ink to pass out of the container, a porous member disposed within the container for transferring ink to the ink supply port, and a projecting member that projects into the container and is formed with an inlet of the ink supply port. The projecting member can engage against and locally compress a portion of the porous member in the region of the inlet of the ink supply port. The projecting member can be formed so that a first region of the container proximal the front wall of the container is shallower than a second region of the container proximal the back wall of the container.

摘要： An ink supply communication path is formed so that one end thereof is arranged outside a region confronting a pressure producing chamber at a region confronting a reservoir chamber; and an ink supply constricted port is arranged at a portion of the ink supply communication path, the portion being remotest from the pressure producing chamber. Since the pressure producing chamber is connected to the ink supply constricted port through the elongated ink supply communication path, a jet flow from the ink supply constricted port grows into a large flow along the ink supply communication path, which in turn allows air bubbles susceptible to stagnation in the vicinity of the ink supply constricted port to be discharged by such large flow.
