摘要:
A method for registering patterns on a web to provide independent scale control in both the lateral and longitudinal directions is provided. The method includes routing the web over a first roller; routing the web over a second roller and stabilizing the web; applying a pattern to the web using process hardware; measuring registration of the pattern and providing an error signal; controlling lateral position error using the error signal; controlling longitudinal position error using the error signal; controlling lateral scale error using the error signal; and controlling longitudinal scale error using the error signal. The method provides independent scale control in both the lateral and longitudinal directions. Independent scale control avoids non-linear distortions otherwise imposed by attempting to accomplish both corrections by stretching the web in both directions.

A method of alignably supporting an eccentric work piece for rotary movements uses a work piece holder that supports the work piece in alignment during rotary operations. A plurality of cooperating aligning members mounted along the rotary axis of a rotary unit, provides pivoting movements relative to the rotary axis while bearing the work piece. These pivoting movements of the aligning members enable the work piece to be aligned during rotary operations.

A method for vaporizing organic materials onto a substrate surface to form a film including providing a quantity of organic material into a vaporization apparatus and actively maintaining the organic material in a first heating region in the vaporization apparatus to be below the vaporization temperature. The method also includes heating a second heating region of the vaporization apparatus above the vaporization temperature of the organic material and metering, at a controlled rate, organic material from the first heating region into the second heating region so that a thin cross section of the organic material is heated at a desired rate-dependent vaporization temperature, whereby organic material vaporizes and forms a film on the substrate surface.

A method is disclosed for forming a liquid pattern of print drops impinging a receiving medium according to liquid pattern data using a liquid drop emitter that emits a plurality of continuous streams of liquid at a stream velocity, vd, from a plurality of nozzles having effective diameters, Dn, arrayed at a nozzle spacing, Sn, along a nozzle array direction that are broken into a plurality of streams of print and non-print drops by a corresponding plurality of drop forming transducers to which a corresponding plurality of drop forming energy pulse sequences are applied. The method is comprised of forming non-print drops by applying non-print drop forming energy pulses during a unit time period, τ0, and forming print drops by applying print drop forming energy pulses during a large drop time period, τm, wherein the large drop time period is a multiple, m, of the unit time period, τm=mτ0, and m≧2; and a corresponding plurality of drop forming energy pulses sequences are formed so as to form non-print drops and print drops according to the liquid pattern data. The corresponding drop forming energy pulse sequences applied to adjacent drop forming transducers are substantially shifted in time so that the print drops formed in adjacent streams of drops are not aligned along the nozzle array direction. Also disclosed is a drop deposition apparatus for laying down a patterned liquid layer on a receiver, according to the disclosed methods, wherein the plurality of nozzles are grouped and shifted to partially or fully compensate for the shift in print position caused by the time shift of energy pulse sequences.

Methods and apparatus are provided for developing a complete set of all admissible Type I and Type II fixture designs for a workpiece. The fixture processor generates the set of all admissible designs based on geometric access constraints and expected applied forces on the workpiece. For instance, the fixture processor may generate a set of admissible fixture designs for first, second and third locators placed in an array of holes on a fixture plate and a translating clamp attached to the fixture plate for contacting the workpiece. In another instance, a fixture vise is used in which first, second, third and fourth locators are used and first and second fixture jaws are tightened to secure the workpiece. The fixture process also ranks the set of admissible fixture designs according to a predetermined quality metric so that the optimal fixture design for the desired purpose may be identified from the set of all admissible fixture designs.
