摘要: A ground anchor load testing system includes a ground anchoring unit having a bare upper drill shaft portion along and around which a reaction anchor with its hollow shaft is temporary installed. During test loading of the installed ground anchoring unit, a test loading head is coupled with both concentric flanging ends of the ground anchoring unit and the temporarily installed reaction anchor. The test loading head exerts via a first coupling the push test load on the first flanging end of the ground anchoring unit while withholding itself via a second coupling on the second flanging end of the reaction anchor. A measurement device may be positioned on the ground adjacent the test load head. Eventual axial displacement of the ground anchoring unit under test load may be externally recognized by the measurement device via an axial displacement indicator in axial connection with the first coupling.

摘要: A method for manufacturing a programmable chalcogenide fuse within a semiconductor device is disclosed. A resistor is initially formed on a substrate. Then, a chalcogenide fuse is formed on top of the resistor. Finally, a conductive layer is deposited on top of the chalcogenide fuse for providing electrical conduction to the chalcogenide fuse.

摘要: A single logic gate array chip is disclosed having a first portion dedicated to the generation of one or more clock signals and the remaining portion occupied by logic circuits. The first portion uses the same gate array cell design as embodied in the logic circuits of the remaining portion. Both portions are powered by similar gate array metallization patterns, although some of the cells of the clock signal sources are disconnected from the normal chip powering busses and are powered instead by respective control signal generators. Each control signal represents the frequency difference between a given clock signal and a reference signal. The cells which are powered by a given control signal introduce a commensurate signal delay to drive the clock signal frequency into a predetermined relationship with the frequency of the reference signal.
