摘要： A novel structure for a bubble-jet type ink-jet printhead is provided. A substrate is covered with a nozzle plate perforated by a predetermined number of nozzle holes a predetermined distance from said nozzle plate. The structure is surrounded by walls, within which form a common ink chamber. Each nozzle hole has, on the substrate underneath, a set of resistive elements. One of the resistive elements encircles an edge of a nozzle hole while another lyes directly underneath the perforation. During operation of the printhead, the encircling elements form a doughnut-shaped bubble forming an imaginary or virtual chamber within the doughnut from the rest of the common chamber. After formation of the doughnut-shaped bubble, the resister underneath the perforation forms a big bubble which causes ink to be ejected through the nozzle hole. The structure that allows for the above is easy to manufacture, and produces high quality print.

摘要： A heater of a bubble-jet type ink jet printhead enabling gray scale and manufacturing method thereof are provided. The heater includes two or more heating elements arranged concentrically around a nozzle. Each of the heating elements is formed in polygonal or annular shape and spaced apart by a different distance from the center of the nozzle. Each heating element is coupled to an electrode for applying heater drive power independently. Thus, the heater drive power is applied to each electrode selectively or in combination, thereby forming bubbles having different volumes.

摘要： A moving object capable of recognizing an image and a system for directing the moving object are disclosed. The system for directing the moving object includes: a charging device on which a docking direction pattern is printed, such that a central point of the docking direction pattern for directing the moving object to a docking location and a power-supply terminal are arranged in a straight line; and a moving object for driving wheel operations to allow the central point of the docking direction pattern captured by a camera to be identical with a central point of an image captured by the camera, and moving to the docking location. The moving-object directing system drives a wheel to track a central point of the docking direction pattern captured by a camera, such that it can quickly and correctly move to the docking location of the charging device.

摘要： An ink cartridge using separate magnets is provided. The ink cartridge includes an ink container, which includes first and second chambers separated by a vertical partition formed therewithin for containing ink, and a head for ejecting the ink in the ink container onto a printing medium in the form of droplets. The first chamber includes a sponge filling most of the inside of the first chamber, a filter provided on a bottom portion of the sponge, and an ink supply pipe for supplying the ink which has passed through the filter to the head. The second chamber includes a magnet float floating on the ink in the second chamber and including a first magnet in its inside, and a second magnet provided in the bottom surface of the second chamber. The ink cartridge includes a magnet sensor for detecting a magnetic flux having at least a predetermined level when the magnet float contacts the second magnet. Accordingly, the ink cartridge with separate magnets does not require a cartridge container to be formed of a transparent material. By using the separate magnets, a magnetic flux having a strength necessary for detection can be induced while preventing magnetic interference between ink containers provided for different colors.
