Abstract: ABSTRACT OF THE DISCLOSURE   A semiconductor laser module comprising a serial arrange-ment of a laser assembly for emitting a substantially collimated beam of light, an optical isolator assembly having an optical isolator housed in a tubular package for transmitting the collimated beam of light with less loss in a forward direction than in a reverse direction, and an optical fiber assembly having a lens for converging and directing the beam from the optical isolator assembly into an optical fiber. There is also dis-closed a method of optimizing the forward loss and isolation characteristics of the optical isolator assembly through adjustment of its angular position about its optical axis which is set at an angle to that of the laser assembly. For such adjustment, not only the isolator assembly is made rotatable relative to the laser assembly, but also the optical isolator itself is made rotatable within limits relative to the tubular package of the isolator assembly.

Title: System and method for editing a structured document to preserve the intended appearance of document elements
Inventor: BORGENDALE KENNETH W
IPC: G06F17/24
Filed: 1991-03-28
Granted: 1998-01-20
Abstract: A data processing system is disclosed for editing a text document stored as at least one alphanumeric string of structured document  text  and displayed  as WYSIWYG text. Look characteristics are controlled for a child document element of the text located within a parent document element of the text. The method performs the step of constructing a child resolved look data set necessary to specify a WYSIWYG appearance of the child element by first accessing modified look value customized by the user for first look parameters and accessing defined look values standardized for second look parameters.  For those look parameters which are not customized by the user or which are not defined as standard values for the child element, the values are inherited by the child element from the parent element.  To do this, the method performs the step of augmenting the child resolved look data set by accessing at least one of the plurality of look values in the parent resolved look data set which does not correspond to the first or the second look parameters. The  resulting  resolved  look  can  completely  specify  the appearance of the child portion of the text when displayed in WYSIWYG form on a display, or when printed in hard copy.

Title: Integrated circuit for processing digital signals in video camera havingelectronic zooming function
Inventor: KAWAKAMI KIYOTADA
IPC: H04N9/74
Filed: 1991-10-31
Granted: 2000-06-27
Abstract: An output from a solid state image sensing device spatially modulated by a color filter is A/D converted and stored in a field memory. Digital signals read from the field memory during electronic zooming are successively delayed by 1H period by means of first, second and third 1H delay elements connected in series. The output from the field memory and outputs from the first, second and third 1H delay elements are separated into luminance components and line sequential color components by first to fourth Y/C separating circuits, respectively. A first set of three primary color signals are calculated based on outputs from the first, second and third Y/C separating circuits, and a second set of three primary color signals are calculated based on outputs from the second, third and fourth Y/C separating circuits. Three primary color signals corresponding to a new display point formed along with the execution of electronic zooming function are formed based on the calculated two sets of three primary color signals, and a luminance signal corresponding to the new display point is formed based on outputs from the first and second delay elements.

Title: Process and apparatus for removal of h2s with separate absorber and oxidizer and a reaction chamber therebetween
Inventor: HARDISON LESLIE C
IPC: C01B17/05
Filed: 1992-04-07
Granted: 1999-04-20
Abstract: A method and apparatus including a reaction chamber interposed in a polyvalent metal redox solution flow path between an absorber chamber and an oxygenation chamber, including one or more oxygenation stages, for contact in the reaction chamber of H2S-laden catalytic polyvalent metal redox solution form the absorber chamber with highly oxidized polyvalent metal redox solution from the last oxygenation stage to accomplish oxidation of the dissolved H2S species by interaction with the oxidized redox catalyst essentially in the absence of gaseous dissolved oxygen.  The highly oxidized polyvalent metal redox solution, including Fe+3 or V+5, contacts the H2S-laden solution from the absorber chamber for reoxidation of the dissolved HS-, S=  and any of the polyvalent metal sulfur compounds (presumably a chelated iron sulfide or a vanadium sulfide), to avoid formation of sulfate or thiosulfate salts which reduce the yield of sulfur and build up in the solution.  To avoid the formation of crystals of iron sulfide or crystals of vanadium sulfide, thereby avoiding loss of polyvalent metal, the residence time of the redox solution after contact with the H2S-containing gas and prior to contacting with the oxidized metal redox solution is limited to a relatively short time. Flow of solution from the last oxygenation stage, preferably through a valve or other circulation control device, to the reaction chamber provides controlled and continuous elemental sulfur formation in the reaction chamber.
