摘要： A channel wafer has a plurality of nozzle flow channels and a common ink reservoir. Pits communicating with the ink reservoir from above heating elements are formed in a polyimide layer on a heater wafer. Each of the pits has a throttled portion in the rear of the heating element and the terminal of a nozzle flow channel is situated on the throttled portion so as to form the minimum sectional area portion of the flow channel. Stable ink discharge characteristics are attained by means of the flow channel resistance of the minimum sectional area portion and bubble pressure is prevented from being relieved toward the ink reservoir. The pressure propagated to the ink reservoir is made to attenuate internally, so that no crosstalk is produced.
摘要翻译：通道晶片具有多个喷嘴流动通道和公共墨水储存器。在加热器晶片上的聚酰亚胺层中形成有来自上述加热元件的与墨水储存器连通的凹坑。每个凹坑在加热元件的后部具有节流部分，并且喷嘴流动通道的端子位于节流部分上，以便形成流动通道的最小截面积部分。通过最小截面积部分的流路阻力来实现稳定的油墨排放特性，并且防止气泡压力朝向油墨储存器释放。传播到储墨器的压力在内部衰减，使得不产生串扰。

摘要： Ink-jet recording apparatus to reduce the change of the pressure of ink in the inside of ink discharge nozzles in an ink-jet recording apparatus as well as to improve the efficiency of use of ink. In the condition where an ink tank is used in an ink-jet recording apparatus, an ink joint provided in the lower end portion of the ink tank communicates with ink discharge nozzles of a head tip. Upon reception of air pressure from above, ink kept by a porous ink keeper stored in the inside of the ink tank is permitted to be supplied to the head tip. The ink tank is formed so that the internal volume of the ink tank increases in order from the lower portion to the upper portion. Accordingly, when the initial residual quantity of ink is relatively large, the change of the pressure (negative pressure) of ink in the inside of the head tip as caused by consumption of ink can be reduced. Further, when the residual quantity of ink is small, ink is collected into a small sectional area region in the lower portion of the ink tank. Accordingly, the finally residual quantity of ink can be reduced.
摘要翻译：喷墨记录装置，用于减少喷墨记录装置中的喷墨嘴内部的油墨的压力变化，并提高油墨的使用效率。在喷墨记录装置中使用墨水盒的情况下，设置在墨水罐的下端部的墨水接头与头部的喷墨嘴连通。在从上方接收到空气压力时，允许储存在墨水罐内部的多孔墨水保持器保持的墨水供应到头部尖端。墨水罐形成为使得墨盒的内部容积从下部到上部依次增加。因此，当油墨的初始残留量相对较大时，可以减少由油墨消耗引起的头部内部的墨水的压力（负压）的变化。此外，当墨水的剩余量小时，墨水被收集到墨水罐的下部的小截面积区域中。因此，可以减少油墨的最终残留量。

摘要： An ink supply passage 16 has a large cross-sectional area and ink tanks 6 are connected to the top of the ink supply passage 16. An ink supply passage 17 is a flow passage shaped like a semicylinder and has a cross-sectional area equal to or smaller than the cross-sectional area of the ink supply passage 16. Even if bubbles are mixed into the ink supply passage 17, they adhere to the upper portion of the flow passage 17 and do not flow into lower corners, so that a flow passage can be provided and the ink flow is not hindered. Since an ink supply passage 19 connected to a head chip 4 has a small diameter, bubbles mixed into the ink supply passage 19 can be removed by maintenance for sucking ink forcibly. Bubbles mixed upstream are not transported to the ink supply passage 19 because of the flow rate difference caused by the cross-sectional area difference.
摘要翻译：供墨通道16具有大的横截面积，并且墨水罐6连接到供墨通道16的顶部。供墨通道17是形状类似于半圆柱形的流动通道，其横截面积等于或小于供墨通道16的横截面积。即使气泡混入供墨通道17中，它们粘附到流动通道17的上部并且不流入下角，使得流动可以提供通道并且墨流不受阻碍。由于连接到头部芯片4的墨水供应通道19具有小的直径，所以通过维护来强制吸入墨水可以去除与供墨通道19混合的气泡。由于由横截面积差引起的流量差，上游混合的气泡不会输送到供墨通道19。

摘要： Considering the differential pressure .DELTA.P between pressures applied to both faces of a meniscus formation member, the differential pressure .DELTA.P becomes the maximum when an ink supply unit is left standing with the meniscus formation member placed upward. At this time, water head PH of ink attempting to fall due to gravity is applied to the inner face of the meniscus formation member in the same direction as negative pressure PR of a capillary member. Thus, the differential pressure .DELTA.P becomes .DELTA.P=PR+PH. The bubble point pressure PB of the meniscus formation member is set greater than the maximum value of the differential pressure, .DELTA.P=PR+PH, whereby air does not enter an ink tank through the meniscus formation member.
摘要翻译：考虑到施加到弯液面形成构件的两个面上的压力之间的压差DELTA P，当向上放置弯液面形成构件而使供墨单元立起时，压差DELTA P变为最大值。此时，试图由于重力而下降的油墨的水头PH以与毛细管构件的负压PR相同的方向施加到弯液面形成构件的内表面。因此，压差DELTA P变为DELTA P = PR + PH。弯液面形成构件的泡点压力PB被设定为大于压差的最大值DELTA P = PR + PH，由此空气不会通过弯液面形成构件进入墨罐。

摘要： An optical sensor has a sensor compensation to compensate for sensor degradation due to airborne contaminations in the operating environment. For example, in a thermal ink jet printing environment, the thermal ink jet operation produces misting or splashing of the thermal ink jet droplets, causing a gradual degradation of the sensor sensitivity due to a surface accumulation of the ink jet droplets. The optical sensor device includes an optical emitter emitting an optical signal according to an emitter input, an optical detector disposed to detect the optical signal and output a detector output having an output level according to the detected optical signal, a variable attenuator having an adjustable attenuation setting, and a controller adjusting the attenuation setting of the variable attenuator. During an adjustment operation, the controller determines the attenuation setting at which the output level of the detector output exceeds a predetermined value, and accordingly sets the variable attenuator to operate the detector output at an output level exceeding the predetermined value by a margin. Compensations for the optical emitter and the optical detector are disclosed, including the use of a variable pulse-width modulated signal.

摘要： A main ink chamber with a through-hole contains a capillary member. An intermediate ink chamber is provided on the side wall of the main ink chamber. A path communicatively interconnects the main ink chamber and the intermediate ink chamber. A second meniscus forming member is disposed in a joint port, to thereby prevent ink leakage. In a print mode, ink flows from the main ink chamber to the joint port, through a meniscus forming member that is disposed in the through-hole. Air bubbles mingled into the ink move along the slanting upper wall of the path by their buoyant force, and are accumulatively stored in the upper part of the intermediate ink chamber. When ink is reduced to zero in the main ink chamber, air bubbles are introduced into the intermediate ink chamber through the meniscus forming member. As a result, the liquid level of the intermediate ink chamber is quickly reduced, thereby indicating a state that ink is used up.
