摘要： A bubble-jet type ink-jet printhead is provided. The ink-jet printhead includes: a substrate; a nozzle plate including a plurality of nozzles, which is separated a predetermined space from the substrate; walls for closing the space between the substrate and the nozzle plate and then forming a common chamber between the substrate and the nozzle plate; a plurality of resistive layers, formed on the substrate within the common chamber corresponding to the plurality of nozzles, each resistive layer encircling the central axis passing through the center of each nozzle; a plurality of pairs of wiring layers formed on the substrate, each pair of wiring layers being connecting to each resistive layer and extending to the outside of the common chamber; and a plurality of pads which are disposed at the outside of the common chamber on the substrate and electrically connected to the wiring layers. The printhead is constructed such that the space between the nozzle plate and the substrate forms a common chamber and there is no ink channel having a complicated structure, thereby significantly suppressing clogging of nozzles by foreign materials or solidified ink. The printhead is easy to design and manufacture due to its simple structure, thereby significantly reducing the manufacturing cost. In particular, its simple structure permits flexibility in selecting a wide range of alternative designs and thus patterns in which the nozzles are arranged. Furthermore, the printhead can be manufactured by a fabrication process for a typical semiconductor device, thereby facilitating high volume production.

摘要： A bubble-jet type ink-jet printhead is provided. When forming a doughnut-shaped bubble, the printhead allows bubbles to be first grown around the heater that surrounds the central axis of the nozzle at regular angles followed by the formation of another bubble between the earlier formed bubbles, thereby forming a larger doughnut-shaped bubble. Accordingly, this can prevent the formation of an unbalanced doughnut-shaped bubble due to variations in local resistance of the heater, which may be caused by a process error. Furthermore, the printhead allows the center of the doughnut-shaped bubble to be set on the central axis of the nozzle thus causing a droplet formed within the doughnut-shaped bubble to be ejected in a normal manner, that is, in a direction vertical to the nozzle plate.

摘要： An ink cartridge for an ink jet printer includes an ink storing portion for containing ink and a head for ejecting droplets of the ink stored in the ink storing portion. The ink storing portion includes a chamber filed with ink in a liquid state, a negative pressure maintaining apparatus for maintaining the pressure of the inside of the chamber to be negative, and a uniform supply guide apparatus, installed between the chamber and the head, for guiding the ink in the chamber to be uniformly supplied to the head. Thus, since the ink is used by being stored in a liquid state, most of the amount of the stored ink can be used for printing, so that the efficiency in use can be improved much.

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： An apparatus for jetting ink including a magnet, a vibrating plate for imposing a pressure upon an ink chamber and coils attached to the vibrating plate. When an electric signal is applied to the coils, the vibrating plate is deformed by a magnetic force produced between the magnet and the coils. At this time, the ink within an ink chamber is ejected to the outside via a nozzle. The quantity and the speed of the ejected ink can be easily controlled while incorporating a simplified structure and a facilitated manufacturing process. Also, printing at a high resolution can be performed at high speed.

摘要： A bubble-jet type ink jet printhead and manufacturing method thereof are provided. In the printhead, a manifold for supplying ink and a concave ink chamber is integrated with a substrate by being recessed from the same surface of the substrate, and a nozzle palate on the substrate in which a nozzle is formed and a round-shaped heater surrounding the nozzle are integrated without a complex process such as bonding. Thus, this simplifies the manufacturing procedure and facilitates high volume production. Furthermore, the round-shaped heater forms a doughnut-shaped bubble to eject ink, thereby preventing a back flow of ink as well as formation of satellite droplets which may degrade image resolution.

摘要： A fluid jetting apparatus includes a nozzle part, a driving part, and a membrane. The nozzle part has an ink chamber and a nozzle hole. The driving part has a working fluid chamber and a heating element. The membrane serves as a partition between the ink chamber and the working fluid chamber. The working fluid chamber has an ink feeding hole through which the ink is fed from an external ink source. An intercommunicating hole is formed on the ink chamber, intercommunicated with the working fluid chamber. The ink is fed into the working fluid chamber and is fed to the ink chamber through an intercommunicating passage. During the heating operation of the heating element, the ink chamber is pressured by the membrane, so that the ink is jetted through the nozzle hole. The ink in the working fluid chamber flows into the ink chamber through the intercommunicating passage, and the ink flows into the working fluid chamber through the ink feeding hole. Accordingly, the working fluid chamber is cooled, and the durability of the fluid jetting apparatus is lengthened.

摘要： An ink tank for an ink jet printer is provided. The ink tank includes a tank body, a sponge disposed in the tank body, for absorbing and storing ink, an air flow member positioned above the sponge, for guiding air outside the ink tank to be induced into the ink tank, a nozzle coupled to one end of the air flow member, for supplying air outside the ink tank to the ink tank, and an air flow hole formed at one side of the tank body connected to the other end of the air flow member, and opened/closed by a sealing means installed on a printer frame according to the movement of the carrier and the ink tank. The air outside the ink tank is supplied only during the printing operation, thereby preventing evaporation of moisture contained in the ink stored in the ink tank. Also, the internal pressure of the ink tank is adjusted to be lower than the atmospheric pressure, thereby preventing leaking of ink.
