摘要： A surface-emission cathode formed on an insulating surface having cantilevered, i.e. “undercut,” electrodes. Suitable insulating surfaces include negative electron affinity (NEA) insulators such as glass or diamond. The cathode can operate in a comprised vacuum (e.g., 10−7 Torr) with no bias on the electrodes and low vacuum electric fields (e.g., at least 10 V cm−1). Embodiments of the present invention are inexpensive to fabricate, requiring lithographic resolution of approximately 10 micrometers. These cathodes can be formed over large areas for use in lighting and displays and are suitable for satellite applications, such as cathodes for tethers, thrusters and space-charging neutralizers.

摘要： A buffer layer is employed to fabricate diamond membranes and allow reuse of diamond substrates. In this approach, diamond membranes are fabricated on the buffer layer, which in turn is disposed on a diamond substrate that is lattice-matched to the diamond membrane. The weak bonding between the buffer layer and the diamond substrate allows ready release of the fabricated diamond membrane. The released diamond membrane is transferred to another substrate to fabricate diamond devices, while the diamond substrate is reused for another fabrication.

摘要： A subcaliber kinetic energy projectile (1) including a penetrator (2) and a segmented sabot (3) which is provided with a front support (4) and with a second support (5) that is disposed at an axial distance behind the first support, with the second support (5) including a rotationally symmetrical air pocket (6) that faces the first support (4) and the first support (4) is provided with air passage openings (43, 44, 45).In the sabot, the relationship of L/D.gtoreq.1.2 exists between the length L of the penetrator tip (8) ahead of the first support (4) and the caliber D. The relationship x.gtoreq.0.45 * .iota. further applies between the distances x and .iota., with x being the distance between the trailing edge (10) of the sabot and the base surface (11) of the air pocket (6) in the second support (5) and .iota. being the distance between the trailing edge (10) of the sabot (3) and the leading edge (12) of the sabot at the surface of the penetrator (2). Finally, the first support (4) is composed of at least three laterally extending web-like components (40-42) whose shape and dimensions are such that they form and have the effect of three separate air pockets.
