Patent CA-2254490-C (CA)
Inventor: LULING MARTIN
IPC: G01V3/20
Filed: 1992-10-30
Granted: 1999-08-24
Abstract: Apparatus and method are disclosed for determining the resistivity of formations surrounding an earth borehole.          An electrically conductive metal body, such as a drill collar on a drill string, is movable through the borehole.  A transmitting toroidal coil antenna is disposed on the body and is energized to induce a current which travels in a path that includes the body and the formations.  An electrode is disposed on the body, and a first signal which depends on the electrical effect of the current on the electrode is measured to obtain an indication of the resistivity of the formations.          In a form of the invention, a second transmitting toroidal coil antenna establishes a second current in the body that travels in a path that includes the body and the formations, and a second signal is measured at the electrode.  A current monitor measures the axial current passing a monitor position on the body, to obtain a monitor current value.  A compensated indication of formation resistivity can then be obtained as a function of the first signal, the second signal, and the monitor current value.  A local communication system facilitates the ultimate communication of information to the earth's surface.

Filed: 1998-07-03
Granted: 2002-08-27
Abstract: In a broadcasting receiver, to quickly switch channels of the received multiplexed broadcasting signals at a high response speed to improve the convenience for a viewer, when broadcasting signals of a plurality of channels are to be code-division-multiplexed and broadcasted from a ground broadcasting station (BC1, BC2) to a broadcasting receiver (MS) in a service area via a geostationary satellite (SAT), the broadcasting signals are multiplexed and transmitted after matching the spreading code phase between the channels in the ground broadcasting station (BC1, BC2). Alternatively, the spreading code phase difference between the channels of a CDM broadcasting signal arriving from the ground broadcasting station (BC1, BC2) is detected in the geostationary satellite (SAT), and the broadcasting signal is transmitted to the broadcasting receiver (MS) after matching the spreading code phase between the channels on the basis of the detection result.
