Title: An optical fiber switching system for laser welding
Inventor: YOSHITANI KATSUMI
IPC: G02B6/35
Filed: 1992-04-23
Granted: 1998-08-04
Abstract: A switching system for selectively distributing a laser beam from a laser source to one of a plurality of welding stations for laser welding thereat.  The system includes a first optical fiber directing the laser beam therethrough, and a pair of second optical fibers leading to the welding stations, respectively.  A switching device connects the first optical fiber selectively to one of the second optical fibers so as to pass the laser beam to the corresponding welding station for enabling the laser welding thereat.  The switching device comprises a housing having a longitudinal axis and holding input ends of the second optical fibers in parallel relation with the longitudinal axis, a carrier supporting an output end of the first optical fiber and linearly movable together therewith within the housing in a direction perpendicular to the longitudinal axis such that the output end of the first optical fiber comes into and out of closely end-to-end facing relation to the input ends of the second optical fibers.  An electromagnetic relay is included to have an armature which is movable between two positions and operatively connected to move the carrier for aligning the output end of the first optical fiber to the input end of a selected one of the second optical fibers for passing the laser beam to the selected one of the second optical fibers.  The output and input ends of the optical fibers are each provided with a heat-radiating sleeve for dissipation of heat.

Title: Method and system for transactioning of modifications to a tree structured file
Inventor: ATKINSON ROBERT G
IPC: G06F17/30
Filed: 1993-07-06
Granted: 2001-11-27
Abstract: A method and system facilitate transactioning of modifica-tions to data. A hierarchical structure organizes data as nodes that contain the data. Each node is designated as transacted or direct. In response to receiving a request to modify data in a transacted node, the modification is associated with the transacted node. In response to receiving a request to commit the modification to file, the modification is dissociated from the transacted node. When the transacted node has an ancestor node that is transacted, the modification is associated with an ancestor node that is transacted. When the transacted node has no transacted ancestor node, the modification is stored directly in the file.      Before receiving the request to commit, a request to revert can cause disassociation of the modification from the transacted node. Depending on storage mode, a modification can be stored in a new or in an old portion of the file.

Granted: 2001-11-20
Abstract: The optical waveguide coupler device (1) is formed on two laterally adjacent optical fibers (4, 5) for splitting with wavelength-flattened ratios an incident light intensity (6) into the two fibers. Adjacent sections of the two fibers (4, 5) are fused together and first and second concatenated tapered portions are formed. These two tapered portions are separated by a central optical waveguide portion (10) including two parallel branches of slightly different lengths, each capable of propagating a light signal from either tapered portion to the other. The first and second tapered portions define optical waveguide couplers (2, 3) presenting coupling ratios varying with optical wavelength in accordance with different curves. The different lengths of the two parallel branches of the central portion (10) cause a shift ~ between the phases of the optical signals propagating through these two branches. The coupling ratios of the tapered portions and the phase shift ~ are selected to wavelength-flatten the coupling ratios of the coupler device (1).

Abstract: A process for fabricating devices is disclosed. Numerous devices are formed on a substrate. The substrate is then placed on an adhesive tape mounted on a dicing ring. The devices are then separated into individual chips by dicing the substrate. Prior to dicing, the substrate is coated with a material that is relatively insoluble in water. After the substrate is diced, the coating is removed by rinsing the substrate with an organic solvent in which the material is substantially soluble. The organic solvent dissolves the coating but does not dissolve the adhesive on the tape or otherwise adversely effect the adhesion between the tape and the substrate.
