    摘要： Disclosed herewith is a microchip having a micromixer therein. The mixromixer employs a mixing or extracting structure having (1) a first flow pass provided at a first level of the microchip; (2) a second flow pass provided at a second level of the microchip, which is different from the first level; (3) a third flow pass having a plurality of sub flow passes separately layered at the first level and each having a first end and second end thereof, each sub flow pass being connected to one of the first and second flow passes at the first end thereof; and (4) a fourth flow pass, provided at the first level, connected to the second ends of the sub flow passes so that, at least connecting portions between the fourth flow pass and the sub flow passes of the third flow pass, an extending direction of the fourth flow pass is substantially identical to those of the sub flow passes. By allowing the first liquid to flow from the first flow pass to the fourth flow pass through the third flow pass while the second liquid to flow from the second flow pass to the fourth flow pass through the third flow pass, the first and second liquids are mixed at the fourth flow pass.

    摘要： Disclosed herewith is an extracting structure for incorporating a substance contained in a first liquid into a second liquid. The extracting structure comprises: a channel for allowing the first liquid and the second liquid to flow therein in a form of a layered flow in which first laminar flows of the first liquid and second laminar flows of the second liquid alternately come in contact with each other, wherein the substance in the first laminar flow of the first liquid moves to the second laminar flow of the second liquid through the boundaries between the first laminar flows and the second laminar flows; and a separating section, connected to a lower stream side of the channel, for separating the second liquid from the first liquid. Further, disclosed also herewith is a separating structure for separating a second liquid from the mixture of a first liquid and the second liquid.

    摘要： An ink jet head for a printer wherein an ink drop is ejected from a nozzle to fly and land on the recording paper to form an image. The ink jet head includes the nozzle for ejecting ink, an ink channel that communicates with the nozzle, a pair of oscillating plates that are opposing to each other on walls of the ink channel, a pair of electrodes disposed in contact with the oscillating plates, an ink chamber for holding the ink, and an inlet for supplying the ink from the ink chamber to the ink channel. A gap between the electrodes is filled with the ink having a relative dielectric constant higher than air. A voltage is applied between the electrodes.

    摘要： An electrostatic inkjet head has first and second electrodes. The first electrode is supported on a substrate and the second electrode is on a diaphragm so that a gap is formed between the first and second electrodes. A drive circuit is connected to the first and second electrodes to apply a voltage or pulse between the electrodes. When a voltage is applied between the electrodes, an electrostatic attraction force is generated between the electrodes. The attraction force displaces the diaphragm toward the substrate. This displacement of the diaphragm is used for the ejection of ink. Also, when the voltage is turned off, opposing central portions of the first and second electrodes define a gap that is greater than that defined by opposing end portions of the first and second electrodes. On the other hand, when the voltage is turned on, the opposing central portions of the first and second electrodes define another gap that is substantially equal to that defined by the opposing end portions of the first and second electrodes.

    摘要翻译： 静电喷墨头具有第一和第二电极。 第一电极被支撑在基板上，并且第二电极在隔膜上，使得在第一和第二电极之间形成间隙。 驱动电路连接到第一和第二电极以在电极之间施加电压或脉冲。 当在电极之间施加电压时，在电极之间产生静电吸引力。 吸引力将隔膜移向基板。 隔膜的这种位移用于喷墨。 此外，当电压关闭时，第一和第二电极的相对的中心部分限定了大于由第一和第二电极的相对端部限定的间隙的间隙。 另一方面，当电压接通时，第一和第二电极的相对的中心部分限定了与由第一和第二电极的相对端部限定的间隙基本相等的另一间隙。
