摘要： An elongate fastener that may not be removed without destruction is provided for insertion in adjacent cooperating holes defined in box structures and their closure elements to maintain closure. The fastener defines a head, larger than the hole to carry the fastener, that structurally carries a peripherally extending tab to aid manual manipulation. The head structurally connects an elongate perpendicularly extending body that fits in the cooperating holes and is formed by spaced peripheral webs that carry barb-like fasteners in their end portions distal from the head that allow insertion of the body through a hole by deformation, but thereafter expand responsive to retentent memory to prevent removal. The interconnection of the body and head is weaker in tensile strength than the material on either side of the interconnection so that the head may be removed from the body by manual manipulation of the peripheral tab, without the use of tools, to allow opening of the box structure.

摘要： A mulitchannel optical waveguide page scanner has a diode laser and a primary optical channel waveguide. Light is coupled from the diode into the primary channel waveguide. Multiple secondary side channels each have a thin-film electro-optic waveguide modulator. A series of T-branch connectors distribute light from the primary channel to the secondary side channels. Each of the electro-optic waveguide modulators is addressable individually.

摘要： A fully integrated electro-optic page-scanner comprises an optically-transparent waveguide made from an electro-optic polymer formed as a Langmuir-Blodgett film, and a linear array of electrically-addressable, spaced, parallel electrodes for selectively altering the refractive index across pixel-sized portions of the polymeric waveguide. Parallel addressing of the electrodes in accordance with the intensity pattern of a line of pixels to be recorded acts to modulate the phase front of an optical wave propagating within the waveguide in accordance with such line intensity pattern. Schlieren optics, also integrated with the page-scanner, convert the phase-front-modulated wave to an intensity-modulated pixel pattern which can be imaged onto a moving photosensitive recording element to record a two-dimensional (page) of image information. By using an electro-optic polymer formed as a Langmuir-Blodgett film as the waveguide, certain disadvantages of prior art scanning devices are eliminated.

摘要： Miscible compositions comprising from about 1 part by weight to about 99 parts by weight of an aromatic polyetherimide and from about 99 parts by weight of about 1 part by weight of an aromatic polybenzimidazole. Preferably, the composition comprises from about 5 parts by weight to about 95 parts by weight of an aromatic polyetherimide and from about 95 parts by weight to about 5 parts by weight of an aromatic polybenzimidazole. In a composition mostly comprised of an aromatic polybenzimidazole, it is preferred that the aromatic polyetherimide be present in the composition in an amount sufficient to make the aromatic polybenzimidazole more thermally processable and also less susceptible to moisture. More preferably, such compositions are comprised of from about 65 parts by weight to about 95 parts by weight of an aromatic polybenzimidazole and from about 35 parts by weight to about 5 parts by weight of an aromatic polyetherimide. In a composition mostly comprised of an aromatic polyetherimide, it is preferred that the aromatic polybenzimidazole be present in an amount sufficient to render the aromatic polyetherimide less sensitive to solvents, and to increase the glass transition temperature of the polyetherimide. More preferably, such compositions are comprised of from about 65 parts by weight to about 95 parts by weight of an aromatic polyetherimide and from about 35 parts by weight to about 5 parts by weight of an aromatic polybenzimidazole.

摘要： Photoconductive compositions comprising an organic photoconductive material, an activator capable of forming a charge transfer complex with the photoconductive material, and a protonic acid. Imaging members provided with an imaging layer prepared from the above composition are highly light sensitive, requiring only brief exposure times, and exhibit a photoinduced state of elevated conductivity which persists long after exposure to light is terminated. These compositions can be returned to their relatively insulative state by merely subjecting the imaging layer to heat in the dark, thereby erasing this photoinduced image pattern of elevated conductivity.

摘要： Electrostatographic imaging method employing an imaging member provided with a photoconductive imaging layer containing an organic photoconductive material, an activator capable of forming a charge transfer complex with said material and a protonic acid sensitizer. The acid sensitization of the charge transfer complex in this imaging layer dramatically enhances the photosensitivity of this photoconductive composition and yet avoids the undesirable memory effects generally experienced in such materials when a photoconductive layer of these materials is imaged in accord with the method of this invention.
