    摘要： An optical subassembly (OSA), in accordance with the present invention, includes a housing, which may be substantially rectangular, the OSA includes a first end portion and a second end portion oppositely disposed from the first end portion. The first end portion forms a bore configured and dimensioned to receive a ferrule having an optical fiber therein. The bore is adjacent to a ferrule stop which is integrally formed in the housing. A lens is integrally formed with the housing. The lens has a planar surface and a convex surface opposite the planar surface. The planar surface of the lens is substantially parallel to and set in from the ferrule stop to prevent contact between the ferrule and the planar surface. The optical device, the lens, and the bore which accepts the ferrule are all in optical alignment.

    摘要： An optical subassembly for transferring light between an optoelectronic converter and an optical fiber where the housing and the lens are of plastic in which the housing is made to dimensions within the precision of molded plastic and the lens imparts focusing properties that compensate for the limitations of the plastic technology. Alignment in the X-Y plane only is employed. The lens has a first surface focused on the optoelectronic converter which substantially collimates the light through the lens and a second surface that introduces deliberate longitudinal spherical aberration that compensates for component position. Attachment or fixing of the optoelectronic converter to the housing is accomplished by RF heating a TO can to quickly cure an epoxylayer.

    摘要： Processes for thermal transfer printing are disclosed which comprise electroerosion printing to produce an image bearing element and exposing the imaged element to irradiation so as to permit transfer of thermographic ink from an associated ink layer or ink-containing element onto an ink receiving substrate thus producing copies of the image carried by the image bearing element. Also, described are products for use in such processes.

    摘要： Improved electroerosion recording media are described in which ablatable polymers are used in the electroerosion recording medium. This medium includes at least a substrate or support layer, a base layer which protects the substrate, a thin film of conductive material on the base layer and which can be eroded, and a protective overcoat layer. Ablatable polymers are used as binders in either the base layer or the top protective layer, or both, in order to provide advantages during electroerosion. These ablatable polymers undergo thermally induced depolymerization in such a way that the result is the formation of volatile monomeric or low molecular weight species as the predominant products, with little or no adherent residue.

    摘要： SLM field access bubble devices which include at least one conductor crossing a bubble propagation path have severely limited operating margins (especially for small bubbles) for the bubble in the vicinity of the conductor. Apparatus and method for operating such a bubble device is disclosed which improves the device operation in this region. The improved apparatus and method provides an additional field source with a sense and magnitude to support the bubble when it reaches the conductor region. Such a field source, as disclosed, includes a current pulse in the conductor.
