Patent EP-0390487-A2 (EP)
Inventor: JEDLICKA JOSEF E
IPC: H01L21/58
Filed: 1990-03-27
Abstract: A process for fabricating a full width array in which plural smaller chips (5A-5N) are bonded end-to-end onto the metallic covering (8) of an elongated substrate (6) by an electrically conductive heat activated adhesive (20) , in which a photocurable adhesive (22) is used to temporarily retain the smaller chips in position while the heat activated adhesive is cured, the process accommodating the inability to cure the photocurable adhesive through the opaque chips and substrate covering by locating the photocurable adhesive so that it extends outside of the boundary (25) of the smaller chips and forms an adhesive fillet or bridge between one side of the smaller chips and the substrate when cured by ultraviolet light. 
     In an alternative embodiment, the photocurable adhesive is located within the boundary of the smaller chips initially but is squeezed out from below the smaller chips to form the exposed adhesive bridge when the smaller chips are placed on the substrate.

Abstract: Color video signals representing gradation values of yellow, magenta, cyan and black components of a halftone original are stored into respective video memories (4) and matrix patterns of screen values are stored in respective areas of a screen memory (7) corresponding to the colors of the video signals. Each matrix pattern has repeating areas extending in a direction inclined to the orientation of the original at an angle φ which satisfies tan φ = 1/(tan ϑ + cot ϑ). Each of the color signals is retrieved from the video memories (4) at line intervals depending on the screen angle ϑ so that if the video signal is reconstructed on a hypothetical plane the line starting points of a resultant image would substantially delineate a line path that is inclined to the orientation of the original by an amount corresponding to the screen angle ϑ of the color of the video signal. The screen values of each matrix pattern are repeatedly retrieved corresponding to the color of the video signal and compared with the retrieved video signal to produce print signals.

Abstract: A power supply which senses whether a primary battery is discharging to below a predetermined dead battery level or the primary battery has been removed and the system is operating from an auxiliary battery, which has a lower voltage. When the battery voltage goes below the dead voltage level, the system is in a low power mode and the power supply output voltages are satisfactory, a timer may be started. If the battery voltage does not drop to the auxiliary battery voltage level within a predetermined time, a shutdown signal is generated and the power supply ceases providing output voltage levels. In this manner the primary battery can be removed and the system can continue running on the auxiliary battery until a charged primary battery is installed and yet the primary battery discharge rate will be greatly slowed when the primary battery voltage is below a given level and the primary battery is still installed in the system.

Abstract: The present invention is a method and an electrical circuit (28 and 50) for effectively eliminating the effects of time jitter caused by metastable states by rejecting measurements made under timing conditions that could lead to the development of metastable states. In a preferred embodiment, the circuit of the invention effectively eliminates time jitter caused by metastable states in digital oscilloscope circuitry by determining in advance the timing conditions that can lead to such jitter and detecting whenever the transitions of trigger and trigger hold-off signals meet such timing conditions. The circuit then generates a "possible metastable" signal that can be used by the oscilloscope circuitry, or by the controlling software, to reject any measurement made under those timing conditions.

Abstract: A system using a ray-tracing algorithm and a hierarchy of volume elements (called voxels) to process only the visible surfaces in a field of view. In this arrangement, a dense, three-dimensional voxel data base is developed from the objects, their shadows and other features recorded, for example, in two-dimensional aerial photography. The rays are grouped into subimages and the subimages are executed as parallel tasks on a multiple instruction stream and multiple data stream computer (MIMD). 
     The use of a three-dimensional voxel data base formed by combining three-dimensional digital terrain elevation data with two-dimensional plan view and oblique view aerial photography permits the development of a realistic and cost-effective data base. 
     Hidden surfaces are not processed. By processing only visible surfaces, displays can now be produced depicting the nap-of-the-earth as seen in low flight of aircraft or as viewed from ground vehicles. 
     The approach employed here is a highly-parallel data processing system solution to the nap-of-the-earth flight simulation through a high level of detail data base. The components of the system are the display algorithm and data structure, the software which implements the algorithm and data structure and creates the data base, and the hardware which executes the software. The algorithm processes only visible surfaces so that the occulting overload management problem is eliminated at the design level. The algorithm decomposes the image into subimages and processes the subimages independently.

Abstract: An information signal modulates a first optical carrier. The information signal is inverted to modulate a second optical carrier. The modulated first and second optical carriers are multiplexed into a single optical signal for communication over an optical fiber path. At a receiver, the optical signal is demultiplexed to recover the information signal and the inverted information signal. The recovered signals are combined to provide the information signal in the electrical domain with reduced distortion. A dual-detector balanced optical diode pair can be used to combine the recovered information and inverted information signals and provide an analog RF output. The apparatus is particularly suitable for the transmission of AM-VSB television signals.

Abstract: A leveling valve (10) for vehicle air springs has an elongated body (15) in which an actuating mechanism (70) is mounted at one end and a valve means (19,24) at the other end with a dampener (50) and a pilot-operated dump means (23) located between the actuating mechanism and the valve means. An elongated plunger (40) extends from the actuating means to the valve means through the dampener and the pilot-operated dump means. One end of the plunger (40) is attached to the actuating mechanism (70) which includes a sleeve (71) slidable on the plunger and on the opposite sides of which are located coil springs (73,74) for maintaining the neutral position of the plunger and valve means. The springs provide a means for permitting over-travel of the actuating mechanism when the plunger reaches its limit of travel and also assist a dump piston (23) in overriding the actuating mechanism. The dampener (50) provides a time delay in the actuating of the plunger (40) which also provides a means for minimizing fluctuations in the actuation of the valve means caused by a vehicle encountering large bumps in the road. The dampener (50) is formed of two transparent parts (51,52) between which is located a piston (54) and a viscous fluid (57) visible through the transparent parts. The actuating means (70) includes rotatable eccentric means (81a,82a,81b,82b) on each side of the sleeve (71) adapted to actuate the sleeve and a forked actuator arm (14) having two arms (14a,14b) connected to each of the rotatable eccentric means.
