Abstract: An ion source head structure of a semiconductor ion implanter including a filament, a filament clamp, a cathode, a cathode clamp, an insulation assembly is provided. The filament clamp clamps the filament. The cathode presents a shell shape and has a receiving space. The filament is located in the receiving space. The cathode clamp clamps the cathode. The insulation assembly is disposed between the filament clamp and the cathode clamp such that the filament clamp is insulated from the cathode clamp. The insulation assembly has a first surface, a second surface opposite to the first surface, and an outer surface between the first surface and the second surface, wherein the first surface of the insulation assembly is in contact with the filament clamp, and the second surface of the insulation assembly is in contact with the cathode clamp. A step difference exists on the outer surface of the insulation assembly.

Abstract: A light-emitting device comprises a textured substrate comprising a plurality of textured structures, wherein the textured structures and the textured substrate are both composed of sapphire; and a light-emitting stack overlaying the textured substrate, comprising a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer, wherein one of the plurality of textured structures comprises a top portion and a bottom portion, wherein a first distance between a first projection of the top portion on the bottom portion and the bottom portion at one side is different from a second distance between a second projection of the top portion on the bottom portion and the bottom portion at another side.

Abstract: A user of an image forming device selects from among a plurality of pre-stored color rendition dictionaries (CRDs) in order that a set of system process parameter setpoints associated with that CRD may be referenced to bias and/or skew an available color gamut in the direction of a particular nominally out-of-gamut color which the user wishes to produce in a color image output by the image forming device. A capability is included in a color image forming device store and/or update multiple sets of special process parameter setpoints defining a plurality of CRDs each of which may be identified and associated with a specific color in order that requests to print out-of-gamut colors may be satisfied routinely as exceptions to a nominal gamut based on a nominal set of stored setpoints when a CRD is selected and the setpoints associated with that CRD are input for reference by the color image forming device on a temporary basis.

Abstract: A color management system is provided for enabling imaging of selected colors called spot colors that document dynamically adjusting the normal printer gamut to achieve extended colors. Developed mass may be increased or decreased by changing set points such as a photoreceptor roll charge, development bias or raster output scanner laser power.

Abstract: A printing system and associated method is provided which is capable of operating in a standard output color gamut mode and/or a non-standard output color gamut mode. According to an exemplary method, the printing system non-standard output color gamut mode is associated with an off-gray balance calibration to extend the gamut of the printing system to include colors outside the gamut associated with the standard output color gamut mode.

Abstract: A marking device is provided which is capable of operating in a standard output color gamut mode or a non-standard output color gamut mode. The device includes: a color manager that performs color processing on input color data in accordance with a calibration of the device; and, a marking engine that applied colorants to an image-receiving medium in accordance with output from the color manager. Suitably, when the device is operating in the non-standard mode, then the calibration of the device which is conducted is an off-gray balance calibration.
