摘要： An improved ink jet head is provided. This improved ink jet head comprises a diaphragm, which is part of an ink chamber. The diaphragm includes a segment which contacts an opposing wall by a drive voltage lower than that for the rest of the diaphragm. The ink jet head also comprises an opposing wall opposite to the diaphragm. When the pressure for ink droplet ejection is generated, the segment of the diaphragm contacts the opposing wall, creating an extremely low compliance state. After ink droplet ejection, the segment of the diaphragm separates from the opposing wall, producing a high compliance state that absorbs the pressure created in the ink chamber by oscillation in the ink channel. Thus, pressure in the ink chamber resulting from ink vibration in the ink path including the ink chamber is buffered to prevent satellite emissions. When plural different gaps are formed between the diaphragm and the opposing wall to create the segments requires different drive voltage for contacting the opposing wall, the part of the diaphragm contributing to ink droplet ejection can be selected by appropriately controlling the voltage applied to opposing electrodes. The mass of the ejected ink droplets can thus be variably controlled. Drive at a lower drive voltage is also possible because contact with the opposing wall is propagated from the segment of the diaphragm to the other parts of the diaphragm. A high ink nozzle density is also achieved in an ink jet head using an electrostatic actuator without increasing the drive voltage.

摘要翻译： 提供改进的喷墨头。 这种改进的喷墨头包括作为墨水室的一部分的隔膜。 隔膜包括通过低于隔膜其余部分的驱动电压接触相对壁的段。 喷墨头还包括与隔膜相对的相对壁。 当产生用于墨滴喷射的压力时，隔膜的部分接触相对的壁，产生非常低的顺应性状态。 在墨滴喷射之后，膜片的分段与相对的壁分离，产生高的柔顺性状态，其通过墨水通道中的振荡吸收在墨水室中产生的压力。 因此，缓冲由包括墨水室的油墨路径中的油墨振动引起的油墨室中的压力，以防止卫星排放。 当在隔膜和相对壁之间形成多个不同的间隙以产生段时，需要不同的驱动电压来接触相对的壁，可以通过适当地控制施加到相对电极的电压来选择有助于墨滴喷射的隔膜的部分。 因此可以可变地控制喷射的墨滴的质量。 在较低的驱动电压下驱动也是可能的，因为与相对壁的接触从隔膜的段传播到隔膜的其它部分。 在使用静电致动器的喷墨头中也可以实现高墨水喷嘴密度，而不增加驱动电压。

摘要： A method of jetting drops of ink from a print head, and a print head adapted to the method are described. The drops of ink are stably jet with a size smaller than the nozzle openings. Described is a method in which a meniscus m that is initially stationary at a nozzle opening is rapidly drawn so that a central region mc of the meniscus is strongly drawn toward a pressure producing chamber. When the movement of the central region of the meniscus toward the pressure producing chamber begins to reverse, the pressure producing chamber is caused to contract to produce an inertial stream and causing the inertial stream to act intensively on the central region of the meniscus close to the pressure producing chamber side. As a result, by pushing only the central region of the meniscus at a high speed, an ink droplet whose size is smaller than the diameter of the nozzle opening is jetted out stably at a speed suitable for printing.

摘要： An ink supply communication path is formed so that one end thereof is arranged outside a region confronting a pressure producing chamber at a region confronting a reservoir chamber; and an ink supply constricted port is arranged at a portion of the ink supply communication path, the portion being remotest from the pressure producing chamber. Since the pressure producing chamber is connected to the ink supply constricted port through the elongated ink supply communication path, a jet flow from the ink supply constricted port grows into a large flow along the ink supply communication path, which in turn allows air bubbles susceptible to stagnation in the vicinity of the ink supply constricted port to be discharged by such large flow.

摘要： An ink-jet recording head, in which two piezoelectric substrates are opposite each other in polarization direction, and grooves are formed across the interface of the two substrates at a predetermined pitch so as to form cavities. One of each of the cavities is opened to the atmosphere and include an orifice adapted for squirting ink drops. The cavities have electrodes formed on their inner surfaces. When a voltage of one polarity is applied to the electrode for the cavity from which ink drops is to be generated whereas a voltage of the other polarity is applied to the electrodes for the two adjacent cavities, the diaphragms separating the three cavities deform in a shear mode towards the cavity from which ink drops is to be generated. As a result, the capacity of the cavity from which ink drops is to be generated decreases to have the ink in the cavity squirt outward from the orifice.

摘要： Droplets of a liquid are ejected through a plurality of nozzles to a plurality of coating regions on a substrate based on nozzle information including the ejection amount of a droplet of the liquid ejected through each nozzle. According to arrangement information for disposing the liquid, a plurality of droplet groups are disposed in each coating region while the plurality of nozzles and the substrate are scanned for relative movement. A calculation is performed according to the nozzle information and the arrangement information. Adjustment amount is calculated so that the assigned adjustment amounts vary from one droplet group to another. Driving signals, which drive selected nozzles, are set so that combinations of the driving signals give coating amounts that have taken the assigned adjustment amounts into account.
