    摘要: An inkjet print cartridge comprising a printhead that is formed using a sequence of etch process steps is described. The first etch of the two etch step process is comprised of a wet chemical etch. A dry etch process follows. Both etch steps are consecutively initiated from the back of the wafer. The fabrication process described offers several advantages including precise dimensional control of the ink feed channel, greater packing density of ink ejectors disposed in the printhead and greater printing speed. Additionally, the time required to manufacture the printhead, in contrast to a conventional printhead, is reduced.

    摘要: A single mask is used to form a tapered nozzle in a polymer nozzle member using laser ablation. In one embodiment of the mask, clear portions of the mask, corresponding to the nozzle pattern to be formed, each incorporate a variable-density dot pattern, where the opaque dots act to partially shield the underlying polymer nozzle member from the laser energy. This partial shielding of the nozzle member under the dot pattern results in the nozzle member being ablated to less of a depth than where there is no shielding. By selecting the proper density of opaque dots around the peripheral portions of the mask openings, the central portion of each nozzle formed in the polymer nozzle member will be completely ablated through, and the peripheral portions of the nozzle will be only partially ablated through. By increasing the density of dots toward the periphery of each mask opening, the resulting nozzle may be formed to have any tapered shape. Other mask patterns are also described.

    摘要: A general winding and feeding apparatus includes a rotating shaft on the upper side of a standing wall of a base, and a motor is connected to the rotating shaft in the standing wall. A swing arm extends across a traveling material and is situated at a suitable position on the standing wall. Digital variable frequency methods may be used to drive the motor, which operates in conjunction with light-coupled sensors to detect the traveling speed of a material on the swing arm and sense a swing position of the swing arm. Feedback is generated in real-time to modify the speed of the motor, and the constant speed travel of the material can be achieved while being either wound or unwound.

    摘要: A microfluidic device includes first and second substrates bonded together. The first substrate has first and second opposed surfaces. A die pocket is formed in the first opposed surface, and a through slot extends from the die pocket to the second opposed surface. The second substrate is bonded to the second opposed surface of the first substrate whereby an outlet of a channel formed in the second substrate substantially aligns with the through slot. The channel of the second substrate has an inlet that is larger than the outlet.
