摘要:
A method for fabrication of vertical nanowire MOSFETs is considered using a gate-last process. The top ohmic electrode is first fabricated and may be used as a mask to form a gate recess using etching techniques. The gate is thereafter formed allowing a large degree in access resistance reduction.

In a method or digital printer to print a recording material with toner particles applied with a liquid developer, toner concentration of the liquid developer is determined via measurement with aid of ultrasonic pulses. At least one ultrasonic pulse is generated by discharging an ultrasound emitter charged with a charge voltage. The ultrasonic pulse permeates the liquid developer and is received by an ultrasound receiver which generates a reception signal corresponding to the received ultrasonic pulse. With a control device, the charge voltage is regulated to a value such that a representative value of the reception signal corresponds to a predetermined desired value. The toner concentration is determined from the regulated charge voltage.

In a method or system for printing of a recording medium, potential images of images to be printed are generated on a potential image carrier. The potential images are developed into an image film comprising image regions and non-image regions on the potential image carrier via application of a liquid developer comprising a polymerizable carrier fluid with dye particles suspended therein. The image film is transferred onto the recording medium. The image film is fixed on the recording medium via a cross-linking reaction of the carrier fluid such that the dye particles of the image regions are embedded in a fixed polymer matrix and the carrier fluid hardens into a transparent film that permanently bonds with the recording medium. The cross-linking reaction of the carrier fluid is started, accelerated, or extended by at least one component.

A printer has a printing drum with recesses on the surface thereof into which ink is provided for printing. After printing, any remaining ink is removed at a cleaning station including immersion in a fluid, air jets, or an air suction. The cleaning station and the inking station operate simultaneously.

In a digital printer a developer element is provided that inks charge images on a charge image carrier with toner. A feed system is provided to apply liquid developer with the toner onto the developer element. The cleaning unit is provided with a cleaning element to clean off residual liquid developer remaining on the developer element after the development of the charge images. A scraping unit rests on the cleaning element made up of a double blade arranged in a blade mount. The double blade provides a cleaning blade and a sealing blade that together form a blade chamber that is filled with fluid. The cleaning blade has at least one row of holes adjacent to a blade edge of the cleaning blade.

In a digital printer comprising a developer station using liquid developer, the developer station has an application unit via which liquid developer is transported to a charge image carrier. The supply system adjacent and lateral to the application unit supplies liquid developer to the application unit. A pre-chamber and an electrode segment are provided, the pre-chamber being filled with liquid developer and open towards the application unit. The pre-chamber is open at a top such that a compensation volume of liquid developer with an open surface is created past which the application unit passes. The electrode segment is arranged adjacent to the pre-chamber and to a side of the application unit such that it forms a gap with the application unit through which the liquid developer is directed, the electrode segment being at an electrical potential such that toner of the liquid developer transfers to the application unit in the gap.
摘要:
In a method or apparatus to optimize transfer of a developer fluid having toner embedded in a carrier fluid in an electrophoretic printing apparatus, charge images of print images are generated on an intermediate image carrier. The print images are inked into toner images by means of a developer station with the developer fluid. The toner images are transfer printed onto a printing substrate in a transfer printing zone by a transfer unit. The toner embedded in the carrier fluid is thus transported from the developer station to the intermediate image carrier in a first transport path segment and from the transfer unit to the printing substrate in a second transport path segment. A temperature acting on the carrier fluid in the first transport path segment is above a melting point of the carrier fluid, and a temperature acting on the carrier fluid in the second transport path segment is below the melting point of the carrier fluid.
