摘要： In an apparatus producing a high-quality and high-resolution image having high water and light resistances with an orifice having a diameter less than &phgr;25 &mgr;m (less than 500 &mgr;m2 in terms of cross-sectional area of the orifice) by use of a fine particle dispersion recording composition, nozzle clogging can be prevented. A recording is accomplished by a liquid jet recording apparatus for ejecting a recording composition including dispersed fine particles from a small orifice toward a receiving medium, wherein a size Dp of the fine particles and a diameter Do of the small orifice are determined by a relationship 0.001≦Dp/Do≦0.01.

摘要： An ink jet recording method includes the steps of inputting a set of driving pulses to a heater element so that the heater element is repeatedly activated by the driving pulses, repeatedly generating a bubble in ink in an ink path in accordance with repeated activation of the heater element, and separately jetting ink droplets from an ink jetting orifice due to the bubble repeatedly generated in the ink, a number of the ink droplets being equal to a number of the driving pulses input as a set to the heater element, the ink droplets jetted from the ink jetting orifice forming a single dot on a recording medium, wherein a time interval at which the driving pulses are input to the heater element is equal to or greater than 4T, T being a time period from a time at which the inputting of the pulses to the heater element starts to a time at which the bubble reaches a maximum size, and each ink droplet is a slender pillar so that a length of each ink droplet is at least three times as great as a diameter thereof. The present invention also relates to other ink jet recording methods and recording heads in which very small ink droplets can be stably jetted in a high frequency.

摘要： An improved printer head for use in a non-impact type printer such as an ink-jet printer is provided. The printer head includes a first flow passage extending from an inlet port, to which ink under pressure is supplied, to a draining port and a second flow passage branching out of the first flow passage and leading to a nozzle aperture directed against a recording medium on which a desired character is to be printed. In the vicinity of the draining port is provided a draining vibrator to which an image or character signal is supplied. Depending on the operating condition of the draining vibrator, the ink is either drained out of the draining port or ejected out of the nozzle aperture. In the preferred mode, a driving vibrator is provided in the vicinity of the inlet port, and the driving vibrator is operated to deflect periodically inwardly to cause the ink to be normally discharged out of the nozzle aperture. The draining vibrator is operated in response to an image signal to deflect outwardly in association with the inward deflection of the driving vibrator to prevent the ink from being ejected from the discharging nozzle.
