摘要:
Standardized card processing modules are mechanically and electrically interconnected to form an application specific card personalization machine. A controller is coupled to a communication bus which permits the controller to download card data to the card processing modules and to upload status information from the card processing modules. Each one of the card processing modules performs a different encoding or personalization function under the control of a local processor.

In various embodiments, sputtering targets are formed by introducing molybdenum powder into a sheet bar mold, pressing the powder to form a sheet bar, sintering the sheet bar to form an ingot having a density of at least 90% of a theoretical density, preheating the ingot, rolling the ingot to form a plate, and heat treating the plate.

In various embodiments, tubular sputtering targets comprising molybdenum are provided and sputtered to produce thin films comprising molybdenum. The sputtering targets may be formed by forming a tubular billet having an inner diameter IDI and an outer diameter ODI, the formation comprising pressing molybdenum powder in a mold and sintering the pressed molybdenum powder, working the tubular billet to form a worked billet having an outer diameter ODf smaller than ODI, and heat treating the worked billet. The sputtering targets may have a substantially uniform texture of (a) a 110 orientation parallel to a longitudinal direction and (b) a 111 orientation parallel to a radial direction.

Refractory metal powders are dehydrided in a device which includes a preheat chamber for retaining the metal powder fully heated in a hot zone to allow diffusion of hydrogen out of the powder. The powder is cooled in a cooling chamber for a residence time sufficiently short to prevent re-absorption of the hydrogen by the powder. The powder is consolidated by impact on a substrate at the exit of the cooling chamber to build a deposit in solid dense form on the substrate.

A multi-station flexographic printing system includes a plurality of flexographic printing stations. Each flexographic printing station includes a flexo master. Each flexo master comprises a Fresnel zone pattern in a unique position. A method of aligning a plurality of flexographic printing stations includes printing a Fresnel zone pattern on a substrate in a unique position for each flexographic printing station. Light is directed through the Fresnel zone patterns on the substrate. The light focused by the Fresnel zone patterns is captured with a sensor device.

In various embodiments, low-oxygen metal powder is produced by heating a metal powder to a temperature at which an oxide of the metal powder becomes thermodynamically unstable and applying a pressure to volatilize the oxygen.

A method for making a light guide includes transferring ink onto a master tool having a three-dimensional feature pattern formed thereon and then transferring ink from the master tool to a transparent light guide. The method also includes curing the ink on the light guide. Alternatively, the ink may be printed onto a substrate (e.g., a film) and then laminated to the light guide.
摘要:
In various embodiments, a sputtering target initially formed by ingot metallurgy or powder metallurgy and comprising a sputtering-target material is provided, the sputtering-target material (i) comprising a refractory metal, (ii) defining a recessed furrow therein, and (iii) having a first grain size and a first crystalline microstructure. A powder is spray-deposited within the furrow to form a layer therein, the layer (i) comprising the metal, (ii) having a second grain size finer than the first grain size, and (iii) having a second crystalline microstructure more random than the first crystalline microstructure. Spray-depositing the powder within the furrow forms a distinct boundary line between the layer and the sputtering-target material.
