摘要:
A method of filling an ink tank with ink for use with a printer, the method includes the steps of providing or obtaining an ink tank which ink tank includes both an ink supply port and an ink fill port that are enclosed within a rim that extends outwardly from the ink tank; providing an ink fill tube connected to a source of ink; connecting the ink fill tube to the ink fill port; flowing ink from the source of ink through the ink fill tube to the ink tank; removing excess air from the ink tank; and withdrawing the ink fill tube from the ink fill port.

A process for making an optical compensator, comprising the steps of coating a orientable resin in a solvent onto a support; drying the resin-containing coating; orienting the resin-containing layer in a predetermined direction; coating a nematic liquid-crystal compound in a solvent carrier onto the orientation layer; drying the nematic liquid-crystal-containing coating; thermally treating the nematic liquid-crystal compound layer, cooling the nematic liquid-crystal compound layer, polymerizing or curing the anisotropic nematic liquid-crystalline layer to form an integral component; and optionally repeating the above steps on top of the integral component so that the optical axis of the first anisotropic nematic liquid-crystal layer is positioned orthogonally relative to the respective optical axis of the second anisotropic nematic liquid-crystal layer about an axis perpendicular to the plane of the support.

An ink tank that is mountable to a printhead, the ink tank includes a wall including an ink outlet configured to supply ink to the printhead; a first film including a sealing portion that is adhered to a sealing area surrounding the ink outlet; and a second film adhered to the first film, the second film configured to capture ink residue when the first film is removed from the sealing area.
摘要:
An ink tank including a reservoir for holding ink, the reservoir including a flexible wall for adjusting an internal volume of the reservoir; a biasing element for applying a force to the flexible wall that tends to increase the internal volume of the reservoir; an ink supply port for delivering ink from the reservoir to a printhead; and a breather element, at least a portion of which is disposed inside the reservoir, including a capillary material in contact with ink in the reservoir, wherein the breather element is configured to allow air to enter the reservoir in response to an internal pressure of the reservoir being less than atmospheric pressure outside the ink tank by an amount that is related to a property of the biasing element and a capillary pressure of the breather element.

摘要:
A method for forming an ink tank for an inkjet printhead, the method includes providing a housing including a back wall, a side wall extending from the back wall, and an ink supply port for providing ink to the inkjet printhead; providing a convex-shaped flexible wall including a peripheral bonding region; inserting a first capillary member into the housing, the first capillary member including a first surface and a second surface opposite the first surface; inserting a spring into the housing such that a first portion of the spring contacts the back wall; affixing the peripheral bonding region of the flexible wall to an edge of the side wall of the housing to form a reservoir for holding ink; removing air from the reservoir such that the flexible wall is drawn toward the back wall; and adding liquid ink to the reservoir such that the liquid ink contacts the first surface of the first capillary member and such that air from outside the housing contacts the second surface of the first capillary member.
摘要:
A method of coating moveable supports at high speeds comprises moving the support along a path through a coating zone, forming two or more layers of coating liquids including an actual top coat layer to form a liquid composition (with a slide hopper coating a plurality of outlets for coating liquids) and applying a starting top most layer of coating liquid, which layer has a lower viscosity than that of the actual top coat layer, to the liquid coating composition either through the first outlet of the hopper or through an x-hopper located between the first outlet and coating zone, applying the coating composition and starting top most layer, and terminating the application of the starting top most layer when the coating operation is at steady state. Apparatus for carrying out this method is also described.
