摘要:
A method of making a repositionable adhesive backed photo media is provided. The method includes the steps of (a) providing an imageable substrate or providing a photograph; (b) providing an attachment mechanism having a carrier film with opposing first and second surfaces; a thermally activating adhesive disposed on the first surface; a repositionable adhesive disposed on the second surface; and a liner disposed on the repositionable adhesive; (c) stacking the imageable substrate or stacking the photograph with the attachment mechanism; and (4) exposing the stack to heat causing the thermally activating adhesive to bond to the imageable substrate or the photograph.
摘要:
Immunoliposomes and use thereof in highly specific and sensitive nucleic acid amplification assays relying on amplification of specific nucleic acid sequences released from encapsulation within a liposome after a receptor on the liposome couples with a targeted analyte/antigen immobilized on a select surface. The immunoliposome nucleic acid amplification assay permits both quantitative and qualitative analyte detection.
摘要:
A method of applying a coating of hot melt polymeric material from a die to a substrate. Hot melt polymeric material is extruded through the die onto the peripheral surface of a rotating application roller to provide a coating layer along that peripheral surface. A substrate is conveyed past the peripheral surface of the application roller at an application interface to cause transfer of the first coating layer to the substrate and shearing and thinning of the coating layer because the substrate is conveyed faster than the peripheral speed of the application roller. The velocity of the peripheral surface and spacing between the die and the application interface along are selected to provide a time interval of at least 0.12 second for movement of portions of the coating layer from the die to the application interface, thereby affording relaxation and molecular reorientation of the hot melt polymeric material after the extruding step to facilitate shearing of the first coating layer at the application interface without causing ribbing or breaking of the coating layer.
摘要:
A method for automatically providing a surface profile analysis of a submicron device using a microscope system typically used to measure critical dimensions of the submicron device is disclosed. The method generates a data point array that is linearly interpolated along a particular scan line measured. The system then calculates an angle for performing a rotational correlation then rotates the measurement profile from the scan line to an absolute horizontal position based on this rotational correlation angle. Next, the system separates the scan line into independent subset features having line and trench features. The number of these line and trench features are then determined in the scan line and using the data point array, the system then calculates the height, width, and angle for each subset feature in that scan line.

A dispenser includes an upper member having a slot and a lower member attached to the upper member thereby forming a housing, the lower member having an outer surface; a stack of sheets assembled in a fan-fold configuration disposed in the housing; and a polymeric holding film having a first surface attached to the outer surface of the lower member. The holding film having a flexural modulus less than about 50 MPa, as measured according to ASTMD790 standard, and a roughness parameter, Ra of less than about 1 micrometer, as calculated according to ASME B46.1 standard.
摘要:
A dispenser package for dispensing flexible sheets from a plurality of stacks of releasably adhered sheets. A carrier member supports the plurality of stacks, and a lowermost sheet of each of the plurality of stacks is adhered to the carrier member. The carrier member and stacks thereon are positioned within an enclosure having a bottom wall, a top wall, and transverse side walls. The top wall defines a transverse slot, with a first end of an uppermost sheet of each of the plurality of stacks projecting through the slot. The transverse side walls of the enclosure are spaced from transverse side edges of the carrier member to afford end-to-end movement of the carrier member and stacks of sheets thereon within the chamber as sheets are dispensed.
摘要:
A label for applying to an optical recording media including a film or paper layer coated with an ink receptive coating on one major surface and a layer of repositionable non-pressure sensitive adhesive coated onto the other major surface.
摘要:
A chlorine dioxide solution generator, which injects a chlorine dioxide solution into a pressurized fluid system, including an absorption loop for effecting the dissolution of chlorine dioxide into a liquid stream. The chlorine dioxide gas source can include an anolyte loop and a catholyte loop. The generator avoids or eliminates the introduction of air or other gases that can cause corrosion in the process distribution system.
