Abstract: A direct distribution wiring system is provided which facilitates the effecting of repair or engineering change in a Multi-chip module (MCM) while eliminating the need for redistribution and/or buried connections between IC attachment pads and engineering change pads, thus eliminating the need for patterned conductor layers corresponding to such functions. The operation of the MCM is improved by the wiring system allowing the reduction of lumped capacitances by disconnection of defective conductors, accomplished by providing severable connectors in a direct distribution structure, as well as the elimination of redistribution wiring layers and increased IC density on the MCM. Full potential fault coverage as well as full discretion in reversible engineering changes is provided by forming all elements of the wiring system on the surface of the device.

Abstract: A lightly doped drain, field effect transistor with an inverted "T"-gate structure has a gate electrode disposed on a polysilicon pad in a stack opening. The inner edge of a lightly-doped source and drain region is aligned with the gate electrode and its outer edge is aligned with an edge of the polysilicon pad. The inner edge of a heavily-doped source and drain region is aligned with the edge of the edge of the polysilicon pad and its outer edge is aligned with the wall surface that forms the opening. The inner edge of a source and drain contact region is aligned with the wall and extends under the stack.

Abstract: An optimized helical resonator which increases the plasma density for efficient processing of semiconductor wafers is characterized by a low inductance and, hence, a low Q. A first embodiment uses either a distributed or lumped capacitance to reduce the value of .omega.L to less than about 200 Ohms. A second embodiment uses a flat spiral coil having a low value of .omega.L and resonant as a 1/4 or 1/2 wave resonator. A third embodiment combines features of the first two embodiments using both spiral and solenoid coils as the helical resonator.

Abstract: The common cold is best treated by providing a combination of antiviral agents and antiinflammatory compounds to a patient infected with a cold virus. An antiviral agent and two antiinflammatory compounds given to a person infected with a cold virus simultaneously reduces the likelihood of a cold developing and the amount and duration of viral shedding, as well as substantially reduces the severity of individual cold symptoms and the overall number and severity of cold symptoms. Supplementing the activity of the combined antiviral and antiinflammatory agents with such compounds as antihistamines and alpha agonists results in suprisingly good nasal benefits. The combination therapy, termed COVAM therapy, is well tolerated and has no evidence of short-term toxicity.

Abstract: In a vector calculation unit (31), a multiplication and an addition result register (50 and 53) are connected to a pipeline multiplier (14) and a pipeline adder (15), respectively. A multiplication and an addition result bus (52 and 55) are connected to the multiplication and the addition result registers, respectively. A selector (S1) connects one of an input bus (11) and the multiplication and the addition result buses to the first operand register to which a first multiplication and a first addition operand bus (44 and 45') are connected. A selector (S2) connects one of another input bus (12) and the multiplication and the addition result buses to the second operand register to which second multiplication and second addition operand buses (48 and 49) are connected. A selector (S3) connects one of the first multiplication operand, the multiplication result, and the addition result buses to an input of the multiplier.

Abstract: An electrically conductive hinge provides for the transmission of electrical power and signals between a pivotally connected display unit and system unit of a portable computer and eliminates cable connections between the display unit and the system unit. Either the system unit, the display unit, or both units have a set of wipers which contact the conductive lines in the electrical track. The conductive lines are long enough to allow the display unit to be pivoted to and from its open and shut positions while the wipers remain in contact therewith. In one arrangement, the electrical track is manufactured on the hinge pin. In another arrangement, the electrical track is manufactured on a disk positioned at or near one end of the hinge pin.

Abstract: A railroad coupler mount includes a hook (20) for contacting the inside upper lip (28) of a coupler head (10) within a single coring hole (12a), a jaw member (22) which engages the rib (18) between a pair of coring holes (12a and 14a), a pad (24) for abutting against an outside surface (26) of the coupler head (10), and a handle (30) for orienting the hook (20) in the transverse or upright positions. In a preferred configuration, end-of-train signalling and monitoring equipment (42) is connected to a railroad coupler mount (44) and the handle (64) which tightens the hook (58) against the inside lip of the coupler head also serves the function of locking a battery compartment door (54) closed.

Abstract: A port output controller for use in a microcomputer for outputting data to a plurality of output terminals in real time, includes a latch circuit for latching data being outputted to the output terminals and a buffer register for storing data to be outputted to the output terminals next to the data being outputted to the output terminals. A timer counter counts an elapsed time after the next data has been latched in the latch circuit and causes the next data stored in the buffer register to be latched into the latch circuit when the counted elapsed time becomes a predetermined data outputting period of time.

Abstract: An intelligent subsystem separately supports inking functions in order to allow stroke-ignorant software to be supported in a stylus driven environment. This subsystem thus provides the inking capability missing in existing flat-panel display controllers. Separate inking functions are incorporated into the subsystem in order to support inking management functions which do not corrupt the display refresh buffer as it is understood by existing application software. The subsystem makes no assumptions about the application's awareness of stroke data as an input modality. Instead, the subsystem assumes that a conventional display subsystem also exists in the system. The subsystem utilizes the strobes and clocks generated by the conventional display controller to generate addresses in a memory which has physically separate address and strobe lines from the display refresh buffer. The content of this added memory is used to control the source of input to the data lines of the display.

Abstract: A process of fabricating an electrical resistor and a product produced thereby in which trimming of a resistive element of a material exhibiting thermosetting properties is accomplished by in-situ annealing of one or more regions across the width of the resistive element to certain predetermined temperatures, thereby altering the crystal properties and the sheet resistance within those regions. Annealing is preferably done by laser radiation at levels below that at which any cutting or ablation of the resistive element will occur, thus avoiding defects in the resistor or associated circuits. By controlling laser radiation and the annealing process, virtually any desired trim slope may be obtained, resulting in improved trimming accuracy. Efficiency of the process is enhanced by annealing the resistive element to obtain compound trim slopes corresponding to coarse and fine trimming of the resistive element.

Abstract: For implementation typically as an IC, a semiconductor decoding device comprises an additional MOS FET (26) of a first conductivity type between ground and output terminals, each (12) of which is connected to a power supply terminal (19) through a load MOS FET (18) of a second conductivity type and to a parallel circuit (13) of a plurality of MOS FET's (14-1etc) of the first conductivity type. Connected to the additional MOS FET and such load MOS FET's and supplied with a control input signal, a charge control section (27) puts the additional MOS FET in a conductive and a non-conductive state while putting each load MOS FET in an off and an on state. Preferably, a current limiting MOS FET (28) of the second conductivity type is connected between the supply terminal and the load MOS FET's and to a current limiting circuit (31-33) for limiting a load current which flows through the current limiting MOS FET and each load MOS FET put in the on state.

Abstract: A communications stimulation system allows a user to perform a quantitative or subjective test of digital baseband devices over wireless channels using actual measured or modeled propagation data. The digital wireless communication simulation system is capable of simulating the transient nature of channels and radio hardware so that loss of synchronization can be included in the simulation. The simulator is a combination of computer software and hardware that computes a convolution, in the time domain, of a sequence of binary digits or data symbols (i.e., the data stream) with a computer model of a radio transmitter, a propagation channel or channels and a receiver. The transmitter typically comprises a coder, a pulse shaper, a modulator, and a spreader. The propagation channel or channels may include impulsive and average noise levels, co-channel interference and adjacent interference levels, fading and multipath propagation events, and non-linear channel and radio system effects.

Abstract: A multilayer, three-dimensional wiring matrix is fabricated from a plurality of individually testable plane pair sub-units (30). Each of the plane pair sub-units (30) includes a compensator (20) with capping layers (32) laminated on either side. The compensator (20) has a dielectric (14) encapsulated foil (10) which has been patterned with holes (12). Metallization patterns on the surfaces of the compensator (20) provide orthogonal wiring (22), electrical connections (24) to the foil (10), and electrical connections (26) between the top and bottom surfaces. The capping layer (32) includes joining metallurgy (38) at selected locations within a dielectric layer (36) that is in registry with the metallization in the vias (16). The joining metallurgy (38) may be a metal loaded thermoplastic and provides a seal for the vias (16) as well as planarizes the structure. The capping layers (32) may be formed in-situ on the compensator or separately.

Abstract: Highly purified and recombinantly produced polypeptides and proteins can be provided to a patient to treat systemic disorders using a metered dose inhaler (MDI). The polypeptides and proteins are solubilized in reverse micelles formed from the surfactant in the MDI propellant. By controlling the molar ratio of water to surfactant, the amount of polypeptide or protein solubilized in the reverse micelles can be controlled, thereby providing an accurate dosing mechanism. In addition, controlling the molar ratio of water to surfactant also can adjust the size and shape of the reverse micelles which will affect the degree and rate of penetration of the lung mucosa for delivery of the drugs to the patient's blood stream. Proteins which may particularly benefit from the solubilization and systemic delivery process include calcitonin, oxytocin, and insulin.

Abstract: A flow meter is provided which employs a thermal flow sensor and a correcting flow meter, for example, a Karman vortex flow meter such that the output from the thermal flow sensor is corrected by the Karman vortex flow meter, thereby making it possible to accurately and stably measure the flow rate of fluids in a wide range even if the composition of fluids changes.

Abstract: A wafer basket having a detachable wafer press means on the back face of the top lid, which resilient press strips are bent and capable of temporarily changing the bent angles in response to external shocks such that the free end of each press strip at which each strip presses on the wafer stays immobile with respect to the edge of the wafer.

Abstract: A multi-processor (MP) system having shared storage is provided with locking of exclusivity status and read only status in multi-processor caches. The multi-processor system includes a plurality of processors, a shared main storage and a storage control element (SCE). The storage control element includes a global access authorization table (GAAT). Locking of exclusivity status in multi-processor caches is accomplished by providing at each processor a local access authorization table (AAT) containing access status for recently used data blocks wherein the size of a data block is a multiple of cache line size. The access status of a block in the local access authorization table is checked when the block is to be accessed by a processor. Only if the access status for a block is not found in the local access authorization table is authorization to access the block requested from the storage control element.

Abstract: An inexpensive and reliable technique for forming connections to a substrate or buried layer of a semiconductor structure employs a laser to melt a small, selected region of a lightly doped layer and a highly doped underlying layer. Extremely rapid diffusion of impurities and mixing of materials within the liquid phase of the melt quickly creates a uniformly doped conductive region when the melt is allowed to recrystallize.

Abstract: A combination of two new access methods for ring and unidirectional bus networks supports high data rate integrated traffic. The first access method provides access for asynchronous traffic. When a node senses the channel idle, it can begin to transmit. When it senses an incoming signal, it must stop transmitting in order to avoid a collision. But unlike other access protocols which abort the transmission when a collision occurs or is imminent, the process truncates the message in a fashion such that it can be resumed later when the channel again is idle. The system is called Carrier Sensed Multiple Access-Ring Network (CSMA/RN). The second access method provides support for synchronous traffic. This method implements one or more circulating reservation packets which permit a node to have reserved space when the special packet returns. The media access system is called Circulating Reservation Packet (CRP) system. Both access protocols operate simultaneously on the network with minimal interference.
