The chopped strands of carbon fibers can be used in spinning. During production, the chopped strands include water, or an organic medium, in which 1-15% by weight of carbonaceous spherules are dispersed. The chopped strands of carbon fibers show no fusion of filaments together, are excellent in separationability and easily disperse in a matrix while maintaining excellent bundling properties.

Abstract: An optical recording medium for storing data is provided having a visible logo on a read side of the medium for providing some anticounterfeiting protection. A logo coating for producing the visible logo is carded by the read-side of the substrate; the coating has a sufficiently high transmittance at a read or write wavelength such that light at the read or write wavelength passing through the logo coating toward the other side of the substrate and reflected back through the logo is substantially transmitted and unchanged by the coating so that the data can be detected as well the coating is sufficiently light absorbing in the visible spectrum such that there is a visible contrast between the recording coating and the logo coating. In another embodiment, the logo coating forms a portion of a reflective recording layer on the other non-read side of the substrate. In this case, the logo coating is visually distinguishable from the rest of the recording layer and is made of a different material.

Abstract: A partly-overlapped portion of a sheath film is meltbonded by heat to provide a seal which a user can tear open with ease. A heat sealing area of the sheath film is halftone printed to reduce the bonding area, thereby decreasing the bonding strength. A tearing portion is provided along the heat seal which is printed so that it has a bonding strength which gradually increases along the tear part until it reaches the bonding strength of the remainder of the heat seal. A curl section having minimal bonding strength relative to the tearing portion of the heat seal is induced to curl up using heat treatment to allow the user to grasp the sheath film at the tear part.

Abstract: A photocopy-resistant document which has a background pattern or logo which is printed with solvent-sensitive, dye based ink and a method of making such a document. The presence of this photocopy-resistant background pattern or logo makes it impossible for a would-be forger of a face-value note such as a bank check to duplicate the original document as a color photocopy. It also makes it impossible for a printing plate to be made based on a photocopy of the document. Besides being photocopy-resistant, the indicia printed with the solvent-sensitive ink are washed away when acetone or bleach solvent is applied to the surface of the document. A fluorescence material can also be added to the solvent-sensitive ink to make the indicia printed with the ink fluorescent under black light.

Abstract: A single-sided ablative write-once optical disk is usable without a protective cartridge. The disk includes the conventional radiation-transparent polycarbonate substrate that has one surface serving as the disk outer face and an opposite surface that supports the fluorinated hydrocarbon subbing layer and the tellurium-based active data layer. The tellurium alloy in the data layer flows to form holes when subjected to incident laser radiation through the substrate. A multilayer protective coating is formed over the tellurium-based layer and has an outer surface that serves as the other outer face for the disk. The multilayer protective coating includes a deformable layer formed directly on the tellurium-based layer and a scratch-resistant hardcoat formed on the deformable layer. The deformable layer has sufficient hardness and modulus of elasticity to permit the tellurium alloy to flow at conventional laser power levels. In one embodiment the deformable layer is a silicone elastomer.
