    • A micro-fluid ejection device structure and method therefor having improved low energy design. The devices includes a semiconductor substrate and an insulating layer deposited on the semiconductor substrate. A plurality of heater resistors are formed on the insulating layer from a resistive layer selected from the group consisting of TaAl, Ta2N, TaAl(O,N), TaAlSi, Ti(N,O), WSi(O,N), TaAlN, and TaAl/TaAlN. A sacrificial layer selected from an oxidizable metal and having a thickness ranging from about 500 to about 5000 Angstroms is deposited on the plurality of heater resistors. Electrodes are formed on the sacrificial layer from a first metal conductive layer to provide anode and cathode connections to the plurality of heater resistors. The sacrificial layer is oxidized in a plasma oxidation process to provide a fluid contact layer on the plurality of heater resistors.
    • 一种具有改进的低能量设计的微流体喷射装置结构及其方法。 这些器件包括沉积在半导体衬底上的半导体衬底和绝缘层。 在选自TaAl,Ta2N,TaAl(O,N),TaAlSi,Ti(N,O),WSi(O,N),TaAlN等的电阻层的绝缘层上形成多个加热电阻体, 和TaAl / TaAlN。 选自可氧化金属并且具有约500至约5000埃的厚度的牺牲层沉积在多个加热电阻器上。 电极从第一金属导电层形成在牺牲层上,以提供与多个加热电阻器的阳极和阴极连接。 牺牲层在等离子体氧化过程中被氧化,以在多个加热电阻器上提供流体接触层。

    • A pivoted hand tool, such as a scissors, includes a pair of blades having non-rectilinear cutting edges to form various cutting patterns on a sheet of paper. The scissors also include at least one guide to control the angular presentation of the paper to the blades and limit the amount of paper presented to the blades. The guide may also include a pair of ridges spaced apart from a pair of abutting surfaces, thereby providing a way to further limit the amount of paper presented to the blades. The scissors preferably have identically-shaped handles and oppositely facing guides to enable a user to create several complementary patterns on the sheet of paper simply by reversing the position in which the scissors are held.
    • 诸如剪刀的枢轴工具包括具有非直线切割边缘的一对刀片,以在纸张上形成各种切割图案。 剪刀还包括至少一个引导件,用于控制纸张向叶片的角度呈现并限制呈现给叶片的纸张量。 引导件还可以包括与一对邻接表面间隔开的一对脊,从而提供进一步限制呈现给刀片的纸张量的方式。 剪刀优选地具有相同形状的把手和相对面向的引导件,以使用户能够简单地通过反转剪刀保持的位置来在纸张上创建多个互补图案。

    • A dispenser for folded paper napkins including an enclosed cabinet having an opening in the front thereof through which napkins may be removed individually. A pair of V-shaped guides are mounted on inside surfaces of opposite sides of the cabinet. A drawer for holding a supply of folded napkins has a pair of V-shaped ribs formed along opposite sides which slidably engage the guides to movably support the drawer within the cabinet. A carriage assembly including a pressure plate for engaging the rear of the napkin supply in the drawer has a pair of V-shaped slides affixed to opposite sides. The sides slidably engage the ribs to movably support the carriage assembly in the drawer. A pair of constant force springs are affixed to the cabinet and engage the rear of the pressure plate to urge the plate and carriage assembly forwardly of the drawer against the rear of the napkin supply to facilitate individual removal of the napkins through the cabinet opening.
    • 一种用于折叠餐巾的分配器,包括一个封闭的橱柜,在其前面有一个开口,卫生巾可以通过该口分开移除。 一对V形导轨安装在机柜相对侧的内表面。 用于保持供应折叠的餐巾的抽屉具有一对沿着相对侧形成的V形肋,其可滑动地接合引导件以可移动地支撑柜内的抽屉。 包括用于接合抽屉中的卫生巾供应的后部的压板的托架组件具有一对固定在相对侧上的V形滑块。 侧面可滑动地接合肋条,以将托架组件可移动地支撑在抽屉中。 一对恒力弹簧固定在机柜上并与压板的后部接合,以迫使板和托架组件向前靠在抽屉的后部,以便于通过橱柜开口单独移除餐巾。
