Abstract: A process and structure are disclosed which are suitable for forming large arrays of Schottky diodes at desired locations between mutually perpendicular strips of aluminum and strips of metal-silicide. The invention is particularly useful in creating read-only memories and programmable logic arrays, and allows fabrication of Schottky diodes more compactly than previous structures.

Abstract: An adaptive word line pull-down circuit steers a pull-down current only to the word being pulled down and only for the time when that word is being pulled down. The time that it takes for the bottom word line to fall controls how long the pull-down current is steered to the falling word.

Abstract: A method and apparatus for exciting the analog input of an analog-to-digital converter and examining the output by means of analysis with histograms to determine the amplitude probability distribution of each digital output value. The amplitude probability density functions corresponding to accurately known excitation signals may then be processed to obtain a description of the transfer characteristic for the analog-to-digital converter to be calibrated. In a particular embodiment, the excitation signals applied to the analog input of the analog-to-digital converter are pairs of signals representing accurately known rising and decaying exponential signals, and particularly exponential signals which are complementary to one another. Histograms of the digital response to the analog excitation signals are then constructed which correspond to amplitude density functions.

Abstract: The present apparatus includes a base and a table movably mounted thereto, further including a body secured to the table and a rod movably mounted to the body. The rod is brought into contact with a member such as a saw blade, and the table and body are moved toward the blade a chosen distance, the rod being moved relative to the body a certain distance corresponding to a certain increase in force being applied to the blade by the rod. For a given increase in force applied to the blade, the movement of the rod relative to the body can be compared to the movement of the table relative to the base to determine deflection of the blade for application of that increase in force thereto.
