Abstract: Abstract A borehole survey instrument has a probe with a polarized light system for transmitting a signal representing the angular orientation of the probe to the surface. Light from a source in the probe is directed through a polarizing filter with an axis of polarization orthogonal to the longitudinal axis of the probe. The polarized light beam is transmitted to the surface through an optical fiber light conduit. The angle of polarization is detected with a rotating polarizing filter and provides a measure of the probe orientation. In surveying a borehole, azimuth is determined from inclinometer measurements. The probe orientation in vertical sections of the borehole is measured by the polarized light system. Two measures of borehole azimuth are combined, providing an improved measure of azimuth in boreholes near vertical and near horizontal.

Abstract: ABSTRACT: Method of recording a digital information signal on a record carrier, record carrier provided with such an information signal and read/write apparatus for such a record carrier.          The invention relates to a method of recording a digital information signal on a record carrier. For a controlled positioning of the read element relative to the track to be read during the read-out of such a record carrier low-frequency tracking signals may be recorded in the tracks. Instead of adding separate tracking signals to the information signal, steps are taken, in accordance with the invention, that these tracking signals are represented by the d.c. content. During conversion of the information words of the information signal into channel words steps are therefore taken to provide to channel words whose d.c. content is equal but opposite for each information word. The choice between these two channel words is made depen-ding on a control signal which depends on the desired tracking signal.

Abstract: TUBULAR JOINT WITH TRAPPED MID-JOINT      METAL TO METAL SEAL                      ABSTRACT      A joint of male and female tubular elements is disclosed where the threads of the female and male members have negative load flanks and have two or more radial steps axially separated one from another by a reverse angle torque shoulder having one or two adja-cent conical sealing surfaces.  The conical sealing surfaces develop radial positional interference and the reverse angle torque shoulder serves as a positive as-sembly stop.  The negative load flank angle of the threads and the reverse torque shoulder angle combine to interlock the male and female members and to pre-vent differential radial separation of the engaged conical sealing surfaces when the joint is exposed to internal pressure, external pressure or both.  Tapered threads and sealing surfaces and interference threads may advantageously be used in the joint construction.

Abstract: RECRYSTALLIZED SILICON-ON-INSULATOR NONVOLATILE MEMORY                          DEVICE          Abstract of the Disclosure Disclosed is a nonvolatile memory device which utilizes a laser beam recrystallized silicon layer having source-channel-drain regions.  Underlying the recrystallized layer and separated therefrom by a memory dielectric is a gate in alignment with the source and drain.  The gate is formed directly on a substrate of an insulative material (e.g. non-silicon materials.         The process of forming the above device comprises forming a conductive polysilicon gate on a substrate followed by a memory nitride layer deposi-tion thereon.  A thick oxide layer is formed over the nitride followed by removal of the thick oxide corres-ponding to a central portion of the gate thereby exposing the nitride therebeneath.  The exposed ni-tride surface is thermally converted into a thin, stoichiometric memory SiO2.  A doped polysilicon layer is then formed on the structure and thereafter conver-ted to recrystallized silicon by subjecting it to laser radiation.  The recrystallized silicon is pat-terned into the device active area and a source and drain in alignment with the underlying gate are im-planted therein.

Abstract: Digital Signal Processor Modem Abstract of the Disclosure A dual speed, full duplex modem for transmitting and receiving data on a dialed-access telephone line includes a signal processor for storing samples corresponding to a sinusoidal waveform, for selecting samples at intervals determined by the mode  in which the modem is operating to synthesize a signal  for modulating by data for transmission,  and for autocorrelating a received signal at a frequency determined by the mode In which the modem is operating to recover data from the received signal. The signal processor includes configuring input ports, and a microcomputer receivers  instructions  related to the mode  in which the modem is to operate to output  a mode-configuring word to the configuring  Inputs. Conversion from the signal processor's digital output to the analog signal to the line and from the line's analog signal to the signal processor's digital   input  takes  place  through  two  time-division  multiplexed coder-decoders.  The stored sinusoid is mu-law compressed.  The modem can dual tone, multiple frequency dial.  The DTMF pair requires a different amplitude from the amplitude of the synthesized signal for modulating by data  for  transmission.   A  power  series  expansion  of  the  required amplitudes of the DTMF tone pair permits both the synthesized signal for modulating by data for transmission and the tones of the DTMF pair to be calculated from the mu-law compressed sinusoid.
