TL;DR: An ink jet recording method which comprises contacting or bringing closer an electro-thermal transducer with or to a recording liquid in an operating chamber having a discharge orifice is described in this article.
Abstract: An ink jet recording method which comprises contacting or bringing closer an electro-thermal transducer with or to a recording liquid in an operating chamber having a discharge orifice, introducing into the electrothermal transducer an input pulse signal with its pulse width being in a range of from 01 μsec to 500 μsec, said input pulse signal being introduced in such a manner that its input cycle becomes at least three times as large as said pulse width, discharging and sputtering said recording liquid from said discharge orifice in the form of fine droplet in accordance with operating force developed within said operating chamber, and effecting image recording on the surface of a recording medium with the liquid droplets

12 Nov 2008TL;DR: In this article, the arrangement of ejection openings is determined so that between the last scanning for completing the black image and the first scanning for printing of the color image, scanning with no performing printing exists.
Abstract: A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.

29 Jan 1997TL;DR: In this paper, an ink-jet recording head includes a discharge-port portion including a first dischargeport portion continuing from a discharge port, and a second dischargeport part communicating the first discharge port portion with a bubble generation chamber.
Abstract: An ink-jet recording head includes a discharge-port portion including a first discharge-port portion continuing from a discharge port, and a second discharge-port portion communicating the first discharge-port portion with a bubble generation chamber. The second discharge-port portion has an end surface that includes a border portion bordering the first discharge-port portion and is parallel to a main surface of an element substrate. The cross-sectional area of the second discharge-port portion, anywhere from an opening surface facing the bubble generation chamber to an end surface facing the first discharge-port portion, that is parallel to the main surface of the element substrate, is larger than the area of the border portion. The cross section of the opening surface of the second discharge-port portion has a length in a direction perpendicular to an arrangement direction of the discharge ports that is greater than its length in a direction parallel to the arrangement direction.

27 Jun 1996TL;DR: In this article, a micromachine is incorporated in a liquid jet recording head to cause recording liquid to flow compulsorily in order to remove accumulated bubbles in the liquid paths for maintaining good performance of the recording head at all times.
Abstract: A micromachine comprises at least one heat generating unit arranged on the surface of a substrate, a housing for retaining liquid having a liquid retaining portion along the heat generating unit, and a rotator rotatively supported in the liquid retaining portion of the housing for retaining liquid. This rotator is structured to rotate by way of the boiling of liquid in the liquid retaining portion by heat generated by the heat generating unit. The micromachine, such a micropump or a micromotor, is incorporated in a liquid jet recording head to cause recording liquid to flow compulsorily in order to remove accumulated bubbles in the liquid paths for maintaining good performance of the liquid jet recording head at all times.

13 Nov 1979TL;DR: In this article, a liquid jet recording method is proposed, which includes controlling thermal energy quantity to be generated by driving predetermined numbers of heat generating bodies selected in accordance with recording information from a plurality of heat-generating bodies which disposed along a flow path in a liquid chamber communicatively connected with a discharge orifice.
Abstract: A liquid jet recording method, which includes controlling thermal energy quantity to be generated by driving predetermined numbers of heat generating bodies selected in accordance with recording information from a plurality of heat generating bodies which disposed along a flow path in a liquid chamber communicatively connected with a discharge orifice for discharging and spattering liquid droplets in a predetermined direction, and each being driven independently of the other; causing the thus controlled thermal energy to act on the liquid in the liquid chamber to bring about instantaneous change in the state of the liquid to develop foams; and discharging and spattering the liquid droplets from the discharge orifice for recording.

TL;DR: In this paper, a source of energy is selectively applied to a liquid stream to reduce the surface tension of the liquid and is applied before the stream would randomly break up into droplets.
Abstract: A source of energy is selectively applied to a liquid stream to reduce the surface tension of the liquid and is applied before the stream would randomly break up into droplets. Both the quantity of energy applied and the time period that the energy is applied are controlled to control the time to droplet breakoff and the time between droplets by selectively reducing the surface tension of segments of the stream. The source of energy can be high intensity light, which is converted by the stream to heat energy, or a source of heat (resistive or inductive) with the resistive heat being applied to the stream by conduction and the inductive heat being converted by the stream to heat energy.
