Patent JO-2950-B1 (JO)
Title: Wellbore mechanical integrity for in situ pyrolysis
Inventor: KAMINSKY ROBERT D
Filed: 2011-08-28
Granted: 2016-03-15
Abstract: A method of completing a wellbore in a subsurface formation is provided herein. The method principally has application to subsurface formations comprising organic-rich rock that is to be heated in situ. Heating the organic-rich rock pyrolyzes solid hydrocarbons into hydrocarbon fluids. The method includes identifying sections along the wellbore where the organic richness of formation rock within the identified zones varies over short distances. Such variance presents a risk of mechanical failure to downhole equipment. The method further includes strengthening the downhole equipment in at least one of the identified sections.

Inventor: TREICHEL HELMUTH
IPC: H01L21/316
Filed: 1987-12-10
Granted: 1992-11-13
Abstract: A method of producing a defined arsenic doping in silicon semiconductor substrates is provided. Preferably, the arsenic doping is produced in the sidewalls and floors of trenches having high aspect ratio which are etched into the substrates. An arseno-silicate glass layer is deposited into these trenches to be used as a diffusion source, the glass layer being removed after the diffusion. The arseno-silicate glass layer is deposited by thermal decomposition from the vapor phase of tetraethylortho silicate Si)OC2H5)4 and triethylarsenate AsO(OC2H5)3. A steep and reproducible doping profile having constant, maximum penetration depth and high arsenic concentration in the substrate surface which is needed for VLSI semiconductor circuits is obtained through the process of the present invention.

Abstract: A parallel frame bit detecting  circuit  of  a  communication equipment for processing distributed frame data includes  a  first variable  frequency  demultiplier,  a  frequency  demultiplier,  a second  variable  frequency  demultiplier  and  a  comparator  for performing parallel detection of the frame bit and shortening  the time required for the detection, thereby reducing the time by  1/4 as compared with that required for the detection of only frame bit of "1100".
