摘要:
A revised image plane translator (RIPT) for a multi-pixel display is made by forming an array of subpixel position cells of refractive index n.sub.a glass frit in a binder, enclosing each cell in lower refractive index n.sub.b or n.sub.c glass frit, vitrifying the array by curing at vitrification temperature for a appropriate time, cutting the array into plates of appropriate thickness to serve as face plates, and then adding appropriate pixel controls and colorations. As a result, the face plate is inexpensive to make, robust, and of very high image quality since each pixel is a cell insulated from its neighboring cells by glass of lower refractive index n.sub.b or n.sub.c ; this traps light within the cell so that the cell can transmit the pixel without interference from its neighboring pixel position cells. There is no loss of resolution due to divergence through the thickness of the face plate. The RIPT serves as a substrate for a liquid crystal display or afield emission display, isolating high-temperature processes for semiconductor deposition and subsequent low-temperature processes for printing the pixel-defining color filters and background. This permits the use of heat-sensitive pixel defining color filters on the outer surface together with an unpatterned phosphor layer on the inner surface.

Method for producing pancreatic islet-like structures (ILS's) having histology and insulin-producing properties corresponding to those of fetal pancreatic islets and islets from adult animals maintained in culture. The ILS's are produced by culturing isolated natural pancreatic islets, pancreatic duct pieces, cell clusters consisting of mildly digested pieces of pancreas, cell tissues obtained as by-products of the culturing methods, or previously-produced ILS's, in attachment to a substrate.

This invention provides processing steps, methods and materials strategies for making patterns of structures for integrated electronic devices and systems. Processing methods of the present invention are capable of making micro- and nano-scale structures, such as Dual Damascene profiles, recessed features and interconnect structures, having non-uniform cross-sectional geometries useful for establishing electrical contact between device components of an electronic device. The present invention provides device fabrication methods and processing strategies using sub pixel-voting lithographic patterning of a single layer of photoresist useful for fabricating and integrating multilevel interconnect structures for high performance electronic or opto-electronic devices, particularly useful for Very Large Scale Integrated (VLSI) and Ultra large Scale Integrated (ULSI) devices. Processing methods of the present invention are complementary to conventional microfabrication and nanofabrication methods for making integrated electronics, and can be effectively integrated into existing photolithographic, etching, and thin film deposition patterning systems, processes and infrastructure.

Methods and systems for generating pulses of laser radiation at higher repetition rates than those of available excimer lasers are disclosed that use multiple electronic triggers for multiple laser units and arrange the timings of the different triggers with successive delays, each delay being a fraction of the interval between two successive pulses of a single laser unit. Methods and systems for exposing nanoscale patterns using such high-repetition-rate lasers are disclosed.

Described herein are processing techniques for fabrication of stretchable and/or flexible electronic devices using laser ablation patterning methods. The laser ablation patterning methods utilized herein allow for efficient manufacture of large area (e.g., up to 1 mm2 or greater or 1 m2 or greater) stretchable and/or flexible electronic devices, for example manufacturing methods permitting a reduced number of steps. The techniques described herein further provide for improved heterogeneous integration of components within an electronic device, for example components having improved alignment and/or relative positioning within an electronic device. Also described herein are flexible and/or stretchable electronic devices, such as interconnects, sensors and actuators.
摘要:
Low mass-per-unit-area plastic film, preferably polyimide, prepared by a process of controlled treating of a supply of plastic film, possibly with one surface reflectively coated, at a microlithography workstation with included photoablation optics. This treatment achieves significant controlled removal of material in a selected pattern by providing relative motion between untreated plastic film and the workstation's photoablation optics while controlling photoablation of a pattern in the film. The material has a significant quantity of the mass of its plastic removed by photoablation, leaving a tessellated pattern of ridges surrounding individual wells. The resulting low-mass, rip-resistant film retains the general attributes of a large-area plastic film. The treated film also retains its reflective surface, on which amorphous silicon may be deposited. The silicon may be thereafter crystallized, utilizing the same optics, and used for fabrication of microelectronics.
摘要:
The invention is a container for liquids, such as milk, juices and wines, which are subject to spoilage enhanced by contact with air. The container may be partially filled with liquid in a sub-chamber made anaerobic by a divider plate positioned on-the surface of the liquid and fitting sufficiently snugly within the container. The divider plate prevents contact between the beverage and air and thus reduces air-induced spoilage. Various embodiments provide springs and divider pullers to place the divider at the liquid surface, easy pouring and easy cleaning. A significant intended use is prolonging freshness of beverages in environments lacking refrigeration.

摘要:
Biological agents such as secretory cells are encapsulated in a hydrophilic gel made of agarose or collagen-agarose and gelatin sponge-agarose combinations. In a preferred embodiment, semi-solid beads are formed from a suspension containing collagen, agarose and secretory cells such as pancreatic islets, the collagen is polymerized to form solid, agarose-collagen beads and the solid beads are coated with agarose. Coating is preferably by rolling the solid beads in about 5-10% agarose, contacting the rolled beads with mineral oil and washing oil from the beads. Beads containing secretory cells can be transplanted into a mammal to treat a condition caused by impaired secretory cell function.
