    • A micro-fluid ejection head structure having multiple arrays of fluid ejection actuators. The structure includes a semiconductor substrate having a first array of fluid ejection actuators for ejecting a first fluid therefrom, and a second array of fluid ejection actuators for ejecting a second fluid therefrom. The first array of fluid ejection actuators is disposed in a first location on the substrate, and the second array of fluid ejection actuators is disposed in a second location on the substrate. A thick film layer having a thickness is attached adjacent the semiconductor substrate. The thick film layer has fluid flow channels formed therein solely for the first array of fluid ejection actuators. A nozzle plate is attached to the thick film layer opposite the semiconductor substrate. The nozzle plate has fluid flow channels formed therein for both the first array of fluid ejection actuators and the second array of fluid ejection actuators.
    • 具有多个流体喷射致动器阵列的微流体喷射头结构。 该结构包括具有用于从其喷射第一流体的第一流体喷射致动器阵列的半导体衬底,以及用于从其喷射第二流体的第二流体喷射致动器阵列。 流体喷射致动器的第一阵列设置在基板上的第一位置,并且流体喷射致动器的第二阵列设置在基板上的第二位置。 具有厚度的厚膜层附着在半导体衬底附近。 厚膜层仅在第一阵列的流体喷射致动器中形成流体流动通道。 喷嘴板附着在与半导体衬底相对的厚膜层上。 喷嘴板具有形成在其中的流体流动通道,用于流体喷射致动器的第一阵列和流体喷射致动器的第二阵列。

    • A dispenser for coiled sheet material which can be operated either through lever action or by a rotatable crank without modification of the dispenser. The dispenser includes a pair of cooperating feed rolls, one of which is a drive roll having a drive shaft. A gear is connected to the drive shaft through a one-way clutch mechanism and a gear segment, which is pivotally connected to the frame of the dispenser, is engaged with the gear. Connected integrally with the gear segment is a lever having a removable knob or handle which extends outwardly through the cabinet of the dispenser. By pushing downwardly on the handle the lever and gear segment will be pivoted to thereby rotate the gear and drive the feed rolls to dispense a length of sheet material. After dispensing, the lever is biased upwardly to its original position by a torsion spring. To convert to a crank mode of operation, the handle is removed from the end of the lever, enabling the biasing mechanism to urge the lever to a further upward position where it will move the gear segment out of contact with the gear, thereby disabling the lever mode of operation. A crank arm can then be removably secured to the end of the shaft, so that rotation of the crank will dispense a continuous length of sheet material.
    • 用于盘绕片材的分配器,其可以通过杠杆作用或通过旋转曲柄操作,而不改变分配器。 分配器包括一对协作进给辊,其中一个是具有驱动轴的驱动辊。 齿轮通过单向离合器机构连接到驱动轴,枢转地连接到分配器的框架的齿轮段与齿轮接合。 与齿轮段一体连接的是具有可移除的旋钮或手柄的杠杆,其可通过分配器的机柜向外延伸。 通过向下推动手柄,杠杆和齿轮段将枢转,从而旋转齿轮并驱动进给辊以分配一段片材。 分配后,杠杆通过扭簧向上偏压到其初始位置。 为了转换为曲柄操作模式,手柄从杠杆的端部移除,使得偏压机构能够将杠杆推动到另一向上位置,在该位置将使齿轮段与齿轮脱离接触,从而禁止 杠杆操作模式。 然后可以将曲柄臂可拆卸地固定到轴的端部,使得曲柄的旋转将分配连续长度的片材。
