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： 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： A thermal electrostatic ink-jet recording apparatus includes an orifice for storing and jetting ink. The orifice is formed between first and second plate members and a longitudinal array of heating elements is formed on one of the plate members and is covered by an insulating layer. An electrically conductive layer is formed either on the insulating layer or the other plate member and cooperates with a counter electrode supporting a recording medium to apply an electrostatic field to ink in the orifice. The electrically conductive layer includes a central portion that extends substantially to the egress of the orifice in the area where ink is contained in the orifice and peripheral portions on either side of the orifice that are not in contact with the ink and that are spaced substantially away from the egress of the orifice. The spacing of the peripheral portion away from the egress of the orifice prevents a gas discharge phenomenon that induces instability in ink jetting.

摘要： An apparatus for developing a latent magnetic image on a moving magnetic recording medium in which the image is always satisfactorily developed without excess toner particles yet using a simple mechanism. A developing magnet extends parallel to the surface of the recording medium, which is in the form of a magnetic drum. The direction of the magnetic field produced by the magnet at the point (line) of closest approach of the recording medium and magnet is the same as the direction of the magnetic field at boundaries between background regions and recorded image regions on the magnetic recording medium. A nonmagnetic rotating sleeve is positioned around the development magnet, and magnetic toner supplied to the outer surface of the sleeve.

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.
