摘要： A method of making a three-dimensional stiffener having at least one wall (6, 8) extending outwardly from a generally planar base portion (4) comprises the steps of forming the base portion by weaving at least two layers (16, 18) using orthogonally disposed first and second yarn lengths (10, 12) and using a third plurality of yarn lengths (14) located within planes extending perpendicularly to the general plane of said stiffener. Each of said plurality of yarn lengths in said third pluratlity is woven between the topmost and bottommost ones (10, 12) of said plurality of first and second orthogonally disposed first and second yarn lengths. At least one stiffener wall (6) extending orthogonally to said plane is formed by overweaving along a given section of said planar portion and in a direction perpendicular to said general plane of said stiffener coincident with a section of one of said plurality of first and second yarn lengths.

摘要： A static induction transistor fabricated of silicon carbide, preferably 6H polytype, although any silicon carbide polytype may be used. The preferred static induction transistor is the recessed Schottky barrier gate type. Thus, a silicon carbide substrate is provided. Then, a silicon carbide drift layer is provided upon the substrate, wherein the drift layer has two spaced-apart protrusions or fingers which extend away from the substrate. Each protrusion of the drift layer has a source region of silicon carbide provided thereon. A gate material is then provided along the drift layer between the two protrusions. A conductive gate contact is provided upon the gate material and a conductive source contact is provided upon each source region. A conductive drain contact is provided along the substrate. Other gate types for the static induction transistor are contemplated. For example, a planar Schottky barrier gate may be employed. Furthermore, recessed or planar MOS gates may be utilized, as may a PN junction gate.

摘要： A process for electromagnetically forming an elongated tubular workpiece (22) by applying an electromagnetic force provided by an energized workcoil (24) to the workpiece radially of its longitudinal axis, and by simultaneously applying an axial compressive force to the workpiece. The radial electromagnetic force forces a section of the workpiece against a forming surface (34) of a die (28). The axial compressive force is provided at one or both ends of the workpiece by positioning one surface of an electrically conductive plate (40, 42) in engagement with an end (44, 46) of the workpiece such that the plate extends transversely to the longitudinal axis of the workpiece, and positioning a flat electrically conductive coil (50, 52) adjacent to but electrically isolated from a second surface of the plate. By energizing the flat coil, a force is created against the plate to thereby compress the workpiece between its ends.
摘要翻译：一种用于通过将通电功卷（24）提供的电磁力在其纵向轴线径向地施加到工件上并通过同时向工件施加轴向压力来电磁地形成细长管状工件（22）的方法。径向电磁力迫使工件的一部分抵靠模具（28）的成形表面（34）。轴向压缩力通过将导电板（40,42）的一个表面定位成与工件的端部（44,46）接合而设置在工件的一端或两端，使得板横向延伸到纵向并且将平坦的导电线圈（50,52）定位成与板的第二表面相邻但电隔离。通过对扁平线圈通电，产生抵抗板的力，从而在其端部之间压缩工件。

摘要： Transistors have source, drain and bulk regions all of the same conductivity type. The bulk region is very thin, not more than about 500 ANGSTROM and preferably about 300 ANGSTROM or even 100 ANGSTROM in thickness. A very thin oxide layer having a thickness of much less than about 100 ANGSTROM , such as 20 ANGSTROM and preferably about 5 to about 10 ANGSTROM , isolates a gate electrode from the bulk region. When operated at temperatures at or below 150 DEG K, such as 77 DEG K, very low threshold voltages, well below 25 millivolts, are achieved. Gigahertz speed complementary MOS transistors, formed by adjacent NNN and PPP devices exhibit power-delay products of about 1E-16 joules operating at supply voltages on order 100 millivolts or lower, making this technology of particular interest for multi-gigahertz processing rates at very low power.

摘要： A liquid cooling system contained completely on a circuit board assembly. The liquid cooling system uses microchannels etched within the circuit board, these microchannels being filled with electrically conductive fluid that is pumped by a non-mechanical, magnetic pump. The pump can be separate from the device on the circuit board which is to be cooled or it can be integrated with the device that is to be cooled. In the latter circumstance, the same current which flows through the electronic device is the current which generates the Lorentz force that pumps the electrically conductive fluid through the microchannel.

摘要： Cooling of densely packaged semiconductor devices is achieved by microchannels which extract heat by forced convection and the use of fluid coolant located as close as possible to the heat source. The microchannels maximize heat sink surface area and provide improved heat transfer coefficients, thereby allowing a higher power density of semiconductor devices without increasing junction temperature or decreasing reliability. In its preferred embodiment, a plurality of microchannels are formed directly in the substrate portion of a silicon or silicon carbide chip or die mounted on a ground plane element of a circuit board and where a liquid coolant is fed to and from the microchannels through the ground plane. The microchannels comprise a plurality of closed-ended slots or grooves of generally rectangular cross section. Fabrication methods include deposition and etching, lift-off processing, micromachining and laser cutting techniques.

摘要： Beam control pulse modulation (CPM) in an RF transmitter tube (101) is provided by a solid state switch on (S1) connected between the cathode power supply (103) and the cathode (102) of the transmitter tube. The beam controlling element (104) is returned to the normal cathode power source such that closing the switch (S1) between the two cathodes and the cathode power source brings the beam controlling element voltage to cathode potential causing beam current to flow, while opening the switch (S1) provides a very high equivalent cathode resistance, which self-biases the tube in the cutoff region, eliminating the need for a separate "off" voltage power supply. Off-edge performance may be further improved by providing an off switch (S2) connected between the cathode (102) and a collector tap on the cathode power supply (103), and closing the switch (S2) when the on switch (S1) is opened to accelerate return of the cathode potential to the cutoff voltage.
摘要翻译： RF发射器管（101）中的光束控制脉冲调制（CPM）由连接在发射器管的阴极电源（103）和阴极（102）之间的固态开关（S1）提供。光束控制元件（104）返回到正常阴极电源，使得闭合两个阴极和阴极电源之间的开关（S1）使得光束控制元件电压成为阴极电位，从而使光束电流流动，同时打开开关（S1）提供非常高的等效阴极电阻，其在截止区域内自发偏置管，消除了单独的“关闭”电压电源的需要。通过提供连接在阴极（102）和阴极电源（103）上的集电极抽头之间的关闭开关（S2），并且在接通开关（S1）上闭合开关（S2）时，可以进一步改善边缘性能，被打开以加速阴极电位返回到截止电压。

摘要： A method of fabricating or forming a tubular member (10) to produce a torque joint wherein the torque joint is formed using an external die arrangement (64) for electromagnetic concurrently forming longitudinal and circumferential or radial grooves in tubular members (10). For the concurrent formation of longitudinal and circumferential or radial grooves (76, 78), the external die (22) which encompasses the area of the components which is to be joined, has grooves (28) or recesses (26) machined in the circumferential inner surface of the die (22) such that upon the generating of an electromagnetic force by means of an internal coil (16) arranged within the area (20) which is to be deformed, the superimposed tubular member (10) is expanded outwardly so as to enter the recesses (26) or grooves (28) which are present in the inner encompassing surface of the external die (22). As a result, the interlocking groove structure or pattern formed in the tubular member (10) produces a torque joint.
