Abstract:
Lateral cathode field emission devices and methods of fabrication are set forth. Conventional integrated circuit fabrication techniques are advantageously used to produce the lateral FEDs. Cathode tips on the order of several hundred angstroms are consistently obtained as well as exact spacing of the cathode to gate and cathode to anode. Various cathode and device configurations are described, including a circular field emission device. A single integrated structure having multiple cathodes and multiple gates is possible to perform various logic operations and/or enhance current output from the device. Multiple field effect devices, with cathodes disposed parallel or perpendicular to the substrate, are integrally coupled through a sharing of one or more metallization layers definitive of the elements of the devices. Significant advantages in current density and circuit layout can be obtained. Methods for fabricating the various devices are also explained.

A device for storing embedded charge includes a first insulator and at least one second insulator. The first insulator has at least two outer surfaces and has a band gap of less than about 5.5 eV. The second insulator is deposited on at least each of the at least two outer surfaces of the first insulator to form at least one interface for storing charge between the first and second insulators. The second insulator has a band gap of more than about 6.0 eV.
Abstract:
A method of fabricating a microchannel plate includes defining a plurality of pores extending from a top surface of a substrate to a bottom surface of the substrate where the plurality of pores has a resistive material on an outer surface that forms a first emissive layer. A second emissive layer is formed over the first emissive layer. The second emissive layer is chosen to achieve at least one of an increase in secondary electron emission efficiency and a decrease in gain degradation as a function of time. A top electrode is formed on the top surface of the substrate and a bottom electrode is formed on the bottom surface of the substrate.

Some embodiments of the present invention disclose a shelving system having one or more support posts with a plurality of shelf connectors connected to the side of the support post. The connectors can be rigidly secured to the posts and/or can extend through the post and have a portion protruding from both lateral sides of the post. One or more shelves can attach to one or more of the shelf connectors at a variety of heights and extend in a variety of directions with respect tot the support post. These shelves can have a plurality of fingers for connection with laterally-extending support pins mounted to the support posts. Some embodiments also employ shelf brackets having bearing surfaces to distribute load from the shelves tot the vertical support posts.

Methods for injecting charge include providing a target comprising a first layer on a second layer, coupling a conductive base to the second layer, and providing a medium which is in contact with at least a portion of the first layer. An electrode is positioned to face and is spaced from the first layer and is at least partially in contact with the medium. An electric field is provided across the first and second layers to inject charge to an interface between the first layer and the second layer.
Abstract:
The present invention is directed to an integrated assembly for gathering information and transferring it to a surface. The assembly comprises a housing, a base resiliently connected to the housing, one or more sensors mounted to sense a parameter and a marker positioned so a mark is produced on the surface when the housing is pressed toward the surface. The marker is capable of marking a plurality of different types of marks. Each type of mark provides different information derived from the sensor. A selector is capable of selecting among the plurality of different type of marks to provide a unique mark specific to a type of information detected.
Abstract:
A power system includes a member with two or more sections and at least one pair of electrodes. Each of the two or more sections has a stored static charge. Each of the pair of electrodes is spaced from and on substantially opposing sides of the member from the other electrode and is at least partially in alignment with the other electode. At least one of the member and the at least one pair of electrodes is moveable with respect to the other. When at least one of the sections is at least partially between the pair of electrodes, the at least one of the sections has the stored static electric charge closer to one of the pair of electrodes. When at least one of the other sections is at least partially between the pair of electrodes, the other section has the stored static electric charge closer to the other one of the pair of electrodes.
Abstract:
A marking attachment for attachment to a linear or angle-measuring system has a support, means for attaching the support to the measuring device, a marking element attached to the support for marking on a surface (the marking element having a predetermined height), and a resilient element whereby the marking element is maintained in a spaced-apart relationship to the surface until the support is moved in a direction substantially perpendicular to the surface to contact the surface with the marking material for marking the surface. The marking element preferably comprises a marking material including an oleate-based pigment ink for marking the surface. The resilient element for maintaining the marking element in a spaced-apart relationship to the surface preferably comprises a quantity of elastomeric material disposed adjacent to marking element, the quantity of elastomeric material having an uncompressed thickness greater than the height of marking element. The resilient element may have an aperture generally surrounding the marking element or may consist of two or more pieces disposed alongside the marking element. Various embodiments have features including a cursor aligned with the marking element and/or including a modular, removable, and replaceable marking element. Any combination of the attachment's support, means for attaching, marking element, and resilient element may be made removable and replaceable.
