An ink tank for use in a printer. In one embodiment, an ink tank includes an outer housing that defines an interior space, and an internal ink bag provided within the interior space, the ink bag being configured to be repeatedly be filled with and deliver ink, the ink tank including a metalized layer having a layer of polymeric material on which has been deposited a metal material.

Refillable ink tanks

An ink supply containing an alkaline ink passivates a silicon diaphragm of a pressure sensor against etching from the alkaline ink using a silicon dioxide layer.

Ink supply

A laser welding system includes a free-spacing beam delivery laser head having a linear array of at least two laser diodes. Each of the diodes generates a laser beam of a predetermined wavelength and spectral width, the laser beams adapted to weld a workpiece having a first component and at least one other component to be welded to the first component, the first component being substantially transmissive to the wavelength, the other component being substantially absorptive of the wavelength. A lens is spaced a predetermined distance from each of the laser diodes, each of the lenses adapted to focus the respective laser beam into a focused laser beam segment, thereby forming a continuous line of laser energy from a substantially serial combination of each focused laser beam segment. The continuous line of laser energy is in a plane containing the workpiece, and is substantially orthogonal to the workpiece translation direction.

The laser beams are adapted to weld a workpiece having a first component and at least one other component to be welded to the first component, the first component substantially transmissive to the wavelength, the other component substantially absorptive of the wavelength. A lens is spaced from the linear array, and directs the laser beams to at least one other lens spaced from the lens. The other lens shapes the laser beams to a predetermined width and length, and focuses the laser beams to substantially the same location, thereby forming a continuous line of laser energy being in a plane containing the workpiece, and being substantially orthogonal to the workpiece translation direction.

A method is provided for depositing a patterning material onto an optically transparent substrate by the use of a laser beam. A solid layer of a patterning material is placed adjacent to a receiving surface of the substrate. A laser beam is directed at an incident angle between 0 and 90&#xb0; relative to the receiving surface. The laser beam is transmitted through the substrate and onto the solid layer to cause patterning material from the solid layer to deposit onto the receiving surface of the substrate.

Laser-assisted deposition

A method for laser patterning of a passive matrix organic light emitting diode device having a multilayered structure comprising a substrate and at least one light emitting organic layer disposed between two electrode layers, the method comprising the step of: irradiating areas of the multilayered structure with a laser beam in a predetermined pattern thereby causing ablation of the multilayered structure in the irradiated areas; wherein, the electrode layers and the light emitting organic layer or layers are patterned substantially simultaneously during the same irradiation operation. Also described are a passive matrix organic light emitting diode device patterned by the method of the present invention and a display comprising the same.

Method for patterning an organic light emitting diode device

A method and apparatus for the removal of mold flash from an IC device using a non-thermal laser ablation method. Ablation is achieved under conditions in which the mold flash is converted to plasma under short laser pulses which do not give sufficient time or energy for significant thermal processes to occur. As a result, the heat sink underneath the mold flash is prevented from heating up due to lack of heat transfer, thereby protecting the heat sink from heat damages. According to one feature of the invention, a mask is provided to protect the molded packaging of the IC device from the laser beam. The mask has at least one hole which corresponds to the heat sink of the device wherethrough the laser beam can pass. According to another feature of the invention, a large beam diameter is provided to increase the efficiency of the deflashing process.
