    摘要: A liquid jet recording head includes a liquid path member having a plurality of liquid flow paths, each of the liquid flow paths being filled with a recording liquid, an orifice being formed at an end of each of the liquid flow paths, and a heater base member having a plurality of heater members and a plurality of radiator members. The heater base member is connected to the liquid path member, each of the heater members having a heater portion, the heater portion generating heat in accordance with a power supplied to it. Each of the radiator members is thermally coupled to the heater portion of one of the heater members so that the amount of heat transmitted from the heater portion to the recording liquid on the heater portion changes in a predetermined direction. When a power is supplied to the heater portion, a bubble is generated in the recording liquid and located at an area on the heater portion, the area having a size corresponding to the power supplied to the heater portion, the bubble causing a recording liquid droplet to be jetted from the orifice.

    摘要: The present ink-jet printer is of the type in which ink droplets are charged under control and deflected by passing through an electric field, and it has two modes of operation: deflection error compensation mode and printing mode. In accordance with the present invention, deflection error is first compensated to determine an optimum amplification gain, which is then used in the printing operation, in which interactive effects with other ink droplets are compensated as well.

    摘要: An on-demand type ink jet printing apparatus which prints out data in various forms such as characters and numerals by the combination of dots formed by ink droplets on a sheet of paper. An ink ejection head of the printer includes control electrodes disposed in at least one ink passageway. Ink droplets are formed and caused to fly by electric fields developed in the vicinity of the control electrodes when voltages are applied thereacross. Multiport ink ejection is achieved by the provision of a plurality of ink passageways in the head. The voltage supply to the control electrodes is controllable so that ink droplets may be formed and caused into flight in response to print signals.A channel defining each ink passageway can be shaped easily yet with accuracy utilizing an etching characteristic particular to a specific crystal face.A plurality of acceleration electrodes may be employed to promote desirable flight of ink droplets. Further, a counter electrode may be located in the head to face the control electrodes so that the ink droplets will be formed and fly in a further efficient and stable manner.

    摘要: An ink jet printing apparatus includes a controllable gain charge amplifier circuit adapted to supply a charging electrode with a charge voltage. A reference charge voltage is coupled to the charging electrode to detect an actual position to which charged ink droplets are deflected. The gain of the amplifier circuit is automatically determined so that the actual deflection position coincides with a predetermined reference position. Moreover, the determined gain of the amplifier is automatically adjusted in accordance with charges on preceding droplets to compensate for any distortion of a charge to be deposited on an immediately following droplet attributed to the charges on the preceding droplets.

    摘要: Ink jet deflection is maintained constant regardless of ink temperature by varying the amplitude of pressure oscillation applied to ink in an ejection head (1) as a function of temperature. The pressure oscillation causes the ink to be ejected from the head (1) and separate into droplets. The droplets are charged and electrostatically deflected where it is desired to print a dot. Variation of the amplitude of pressure oscillation changes the shape of the droplets and thereby the amount of charge thereon and the deflection.
