摘要： A non contacting angular differential displacement torque sensor utilizes a split shaft with a connecting torsion bar with a pair of receive disks each with an intervening coupler disk carrying a conductive attenuating pattern where the inductive coupling between transmit and receive disks is individually attenuated in accordance with the angular position of the shaft on which the disks are mounted. The pair of receive disks which receive signals from a common transmitter have their angular difference taken and this is the actual torque on the shaft.

摘要： This patent application is to use dynamic electromagnetic wave reflection and refraction methods for prospecting for oil directly. The available geophysical methods including the most used seismic reflection method are all prospecting for oil indirectly, viz., aiming at finding the geological structures and stratigraphic traps, etc. The high contrasts of electric permittivity between oil cord the surrounding geological formations of rocks including gas, water (fresh and salt), on the other hand, make it possible to use the dynamic electromagnetic wave reflection and refraction methods for prospecting for deep seated oil directly.
