摘要： An ink-jet printhead accepts a series of digital addresses as image data. Each digital address causes an individual ejector in the printhead having the particular address to be activated. The frequency of operation of the printhead can be directly related to the frequency at which addresses are submitted to the printhead. A scheduler polls image data for spot placements which require simultaneous activation of a plurality of ejectors in a set of interdependent ejectors, and then reschedules the activation of ejectors to avoid conflicts.

摘要： Methods and apparatus provide for automatic fluid ejector alignment and performance evaluation and modification in one or multiple planes. A fluid ejector fires a drop through a drop detection module. A signal indicating drop presence or absence is sent to a computer. The computer analyzes the data, and makes a compensation determination of a preferred method of using the fluid ejector. The compensation determination may include electronically modifying the image data to be printed, physically manipulating the fluid ejector, completely skipping the fluid ejector during printing operations, or in some other way modifying the fluid ejector or image data such that apparent printed image error due to fluid ejector alignment or performance error is reduced.

摘要： When a thermoplastic spacer is applied to a glass pane in the production of insulating glass panes, the nozzle from which the plastic with the desired cross sectional shape is extruded along the edge of the glass pane. The speed with which the plastic is applied along the edge of the glass pane is chosen depending on the temperature of the plastic. Here, for a stipulated temperature setpoint the speed with which the plastic is applied along the edge of the glass pane is stipulated. If the temperature increases, the speed is increased; conversely, when the temperature drops below the setpoint, the speed with which the plastic is applied along the edge of the glass pane is reduced. This ensures that the correct amount of thermoplastic is always extruded onto the glass pane and a spacer with a uniform cross section is obtained.
摘要翻译：当在绝缘玻璃板的制造中将热塑性间隔物施加到玻璃板上时，具有期望的横截面形状的塑料沿着玻璃板的边缘被挤出的喷嘴。根据塑料的温度选择沿玻璃板边缘施加塑料的速度。这里，对于规定的温度设定值，规定沿着玻璃板的边缘施加塑料的速度。如果温度升高，速度增加; 相反地，当温度降到设定点以下时，沿玻璃板边缘施加塑料的速度降低。这确保了正确量的热塑性塑料总是被挤压到玻璃板上，并且获得了具有均匀横截面的间隔物。

摘要： In an ejector for a thermal ink-jet printhead, a heating element exposing an area to liquid ink in the printhead includes an insulative layer around the lateral edges thereof, particularly those edges not having conductors associated therewith. This insulation creates a more uniform temperature distribution over the heating area, resulting in a uniform nucleation of a vapor bubble within the liquid ink.
