摘要： In a system for laser welding upper and lower work pieces along a weld interface, the upper work piece being transparent to laser light and having a non-uniformly thick dimension, compensation plates and compliant members are taught that mate or otherwise contact the upper work piece such that a combined thickness of the upper work piece and the compensation plate or compliant member is substantially uniform in a region at least above the weld interface. In this manner, substantially consistent amounts of laser light reach the weld interface. The upper work piece may include positive projections, negative voids, contoured profiles, surface imperfections or other that cause the non-uniformity. In one embodiment, the compensation plate is fashioned together with a compliant member. In another embodiment, the upper and lower work pieces comprise inkjet printhead lids and bodies, respectively.

摘要： In a system for laser welding work pieces along a collapsing weld interface, methods and apparatus include providing welding pads and/or stop projections on either or both of the work pieces to control the manner or amount of collapse. Preferably, the stop projections exist a separation distance from the weld interface while the welding pads exist at and form a portion of the weld interface. Buffers are taught between the weld interface and stop projection. The work pieces may comprise inkjet printhead lids and bodies. In another aspect, the invention teaches methods of laser welding inkjet printhead lids and bodies according to whether the inkjet printhead body embodies a mono or color ink body type and especially includes selective control of one or more laser light sources to illuminate the inkjet printhead lid in a specific pattern of light.

摘要： Multi-compartmentalized ink cartridges for ink jet printers and improved methods for making the ink cartridges. The multi-compartmentalized ink cartridge includes a molded, open-topped body having an interior cavity and a printhead surface area opposite the interior cavity. A divider wall is integrally molded with the molded body structure and disposed in the interior cavity to provide at least three segregated ink chambers. The divider wall includes a first wall section and a second wall section attached substantially perpendicular to the first wall section. At least first, second, third molded ink flow paths connect each of the at least three segregated ink chambers with the printhead surface area. The second and third ink flow paths are oriented relative to their corresponding ink chambers for molding with a mold insert tool so that the cartridge body does not require a separately attached member to close mold insert tool insertion areas in the body.

摘要： An inkjet printhead having a unitary body with an ink conduit between an ink outlet port of an ink compartment and an ink feed slot compatible with a heater chip has an ink conduit plug laser welded thereto to prevent ink from leaking from the ink conduit as the ink flows from the ink outlet port to the ink feed slot during use. In one embodiment, the ink conduit plug has a lid and an insertion portion. The lid has a laser transparent periphery that becomes illuminated with a laser light to weld an undersurface thereof over an opening of the ink conduit. Techniques for laser welding include an advancing laser beam or a simultaneous welding structure. In another embodiment, the ink conduit plug has two plug sections banded together with either a flexible material or angularly disposed links. The banded plug sections may or may not be laser welded.

摘要： Ink delivery systems achieve balanced ink flow by positioning two or more ink chambers around ink ejection mechanisms in a printhead. A plurality of pie-shaped ink chambers may be arranged in a circle above an ink ejection mechanism, which provides short ink paths from each ink chamber, and ink paths having approximately the same length. This fosters even ink flow rates and equal pressure drop/loss of ink supplies, thereby improving ink feeds to a printhead and providing improved jetting efficiency and printhead performance.
摘要翻译：墨水输送系统通过在打印头中的墨水排出机构周围设置两个或更多个墨水室来实现平衡的墨水流动。多个饼形墨水室可以布置在喷墨机构上方的圆圈中，其从每个墨水室提供短的墨水路径，以及具有大致相同长度的墨水路径。这促进了墨水流量和墨水供应的相同的压降/损失，从而改善了对打印头的墨水供给，并提供了改进的喷射效率和打印头性能。

摘要： A removable ink tank includes a floor including an ink output port. A free ink chamber is located over the floor. A suspended ink chamber is located over the floor and around the ink output port. The suspended ink chamber is separated from the free ink chamber by a divider wall. The divider wall has an ink communication port located near the floor to facilitate fluid communication between the free ink chamber and the suspended ink chamber. A frame is formed around the ink communication port. The frame protrudes outwardly into the suspended ink chamber to ensure a good seal with the ink suspension member.
