Patent DE-3382069-D1 (DE)
Inventor: CHAMPOUX ROBERT L

Granted: 1991-01-31
Abstract: The method of fastening a plurality of metal members (82,84; 232, 230) in which precision holes (86, 88; 236,234) are drilled through the metals which are to be connected together. The drilled holes in the metal members are cold-expanded to improve the fatigue performance of the metal surrounding the hole and at the sametime size the hole. Then a fastener (254) sized to make a desired fit is installed into the hole. The final hole diameters (236A, 234A) after expansion are equal to the starting hole diameters plus the retained expansions, there being spring back shrinkage of the expanded holes to the final hole diameter. The holes are sized by expanding them to at least a critical sizing expansion value which is a value of expansion beyond which the retained expansion value is linearly exceeded and to nearly the same amount as the total expansion before elongation of the hole axis of the metal surrounding the hole. This is a method of cold-expanding a series of holes to size in which the same tools are used, with the result that the holes are varied in the diameter no more than 0.001".

Title: Electronic matrix arrays and method for making, parallel preprogramming or field programming the same
Inventor: JOHNSON ROBERT ROYCE
IPC: H01L45/00
Filed: 1984-01-13
Granted: 1989-08-03
Abstract: A method of making a parallel programmed electronic matrix array includes forming at least one layer of a phase changeable material on a conductive substrate, the material preferably formed of amorphous material and having substantially nonconductive and comparatively high conductive states, and irradiating selected areas of the layer to convert them to the other state. Thereafter, in a preprogrammed embodiment, first and second sets of electrically conductive address lines are formed on respective opposite sides of the layer such that they cross each other at an angle to form a plurality of crossover points. In a field programmable array, the selected areas are irradiated through one set of lines.In accordance with another embodiment, the selected areas are irradiated through a mask. One set of lines is preferably formed by removing portions of the conductive substrate. The other can be formed by detecting the locations of the layer portions of one of the states and aligning the lines on the layer according to such detection.A diode structure can be formed with or in place of the phase changeable material.

Abstract: In the vehicle, a wheel turns sensor (18) for distance measurement and a compass (20) for direction, and a display (66) and keyboard (68) are connected to computer (14) via input/output interface (56). Coordinate data for the grid are stored in memory (12) and for numerous reference points on the road network e.g. junctions, in memory (16). At the start of a journey the keyboard and display are used to load local grid and road reference points data into working memory (62) and to insert starting position e.g. a reference point. As the journey proceeds vehicle position is computed by dead reckoning at fixed distance intervals such as 125 metres in town or 1000 metres out of town and the current estimated position data stored in memory (22). Another memory (24) stores the coordinates of the boundaries of the square in which the vehicle is presently situated and when the computed position indicates that a new square is entered the data in memory (24) are changed, and the position data in memory (22) modified so as to be relative to the sides of the new square. To cancel cumulative errors on long journeys, computed position can be corrected from the keyboard and display upon arrival at a new reference point.
