  • Patent number: 6511716
    Abstract: Ultraviolet rays are radiated over a lubricant film formed on the surface of a recording medium such as a hard disk. The recording medium is then subjected to exposure to a bases. The radiation of the ultraviolet rays allows the lubricant film to uniformly spread over the surface of the recording medium. The repellency can be enhanced over the surface of the recording medium. The friction can be reduced on the recording medium. Moreover, when the recording medium is exposed to the base, organic acid existing on the surface of the recording medium and/or in the lubricant film can be transformed into salt. The organic acid can be washed off or removed from the surface of the recording medium and/or out of the lubricant film in this manner. Less organic acid greatly contributes to prevention of generation of corrosion mounds on the recording medium over a longer period.

  • Patent number: 6423382
    Abstract: A high gloss coating on a mineral substrate, such as a roof tile or floor tile, can be achieved by a method comprising: i) applying a first coating consisting of an aqueous composition comprising a film forming polymeric binder to a surface of the uncured substrate; ii) exposing said first coating to hot air or infrared, ultraviolet or microwave radiation, for sufficient time for at least the surface of said coating remote from the substrate body to form a film of polymeric binder, and iii) applying a second coating consisting of an aqueous composition comprising a film forming polymeric binder on top of the first coating. After application of the second coating, the substrate and coatings are dried and cured, for example in an oven or autoclave.

  • Publication number: 20020090565
    Abstract: Electrically (and, possibly, mechanically) active patterns are applied using a colloidal suspension of nanoparticles that exhibit a desired electrical characteristic. The nanoparticles are surrounded by an insulative shells that may be removed by therefrom by application of energy (e.g., in the form of electromagnetic radiation or heat). The nanoparticle suspension is applied to a surface, forming a layer that is substantially insulative owing to the nanoparticle shells. The applied suspension is exposed to energy to remove the capping groups and fuse the particles into cohesion. If the nanoparticle suspension was deposited as a uniform film, the energy is applied in a desired pattern so that unexposed areas remain insulative while exposed areas exhibit the electrical behavior associated with the nanoparticles. If the nanoparticle suspension was deposited in a desired pattern, it may be uniformly exposed to energy.

  • Patent number: 6406758
    Abstract: A method of applying a protective coating to a touch screen panel. A coating material which cures at an elevated temperature is applied to a touch screen panel on at least one surface thereof. The panel is then heated to a temperature which does not adversely affect the panel by irradiating the panel imparting energy to the coating material to more fully cure the coating material in a shorter time period without damaging the panel.

  • Patent number: 6399280
    Abstract: According to the present invention there is provided a method for making a lithographic printing plate comprising the steps of applying a first magnetic field to a dry, light absorbing powder, which comprises a magnetic material and a hydrophobic thermoplastic binder, thereby coating said powder on a surface of a metal support; image-wise exposing to light the powder in contact with the surface of the metal support, thereby increasing the adhesion of the powder to the surface of the metal support, without substantially ablating the powder; and removing the non-exposed magnetic powder from the surface of the metal support under action of a second magnetic field with a polarity substantially opposite to the first magnetic field.

  • Patent number: 6399012
    Abstract: Varistors are produced by pressing ceramic ZnO powder to provide discs, sintering the discs with microwave radiation, and firing outer electrodes with microwave radiation. The sintering has a maximum plateau temperature of 1000° C. to 1300° C. and the duration for ramping to this temperature and maintenance at this temperature is 120 to 180 minutes. These parameters also apply for multi-layer varistors with inner electrodes. The outer electrodes are fired at a maximum plateau temperature of 550° C. to 820° C. for a total duration of 40 to 45 minutes.

  • Publication number: 20020048637
    Abstract: In a method for producing a magnetic recording medium, at least one magnetic layer is formed on a nonmagnetic support by coating. After all coating processes are completed, heat treatment is performed by heat-treating the support, which is undergone all the coating processes, at 95 to 140° C. for 1.0 to 10.0 seconds with continuously applying tension of from 1.0 to 4.0 kg/m to the support. Then, calendering process is performed at a temperature lower than the temperature of the heat treatment.

    Abstract: A coating powder comprising a macrocyclic oligomer and a ring-opening polymerization agent is applied to an article, fused, and converted to a linear polymer at a temperature of from about 160 to about 400° C. The powder has the low melt viscosity and friability of a thermoset powder but is converted at high fusing temperatures to a tough coating having the good impact resistance and good elongation of a thermoplastic powder. The oligomer is a polyester, polycarbonate, polyamide, polyimide, polyamideimide. The article may be coated electrostatically or in a fluidized bed.

  • Patent number: 6350496
    Abstract: A method of making permanent drawings and markings on a mosaic tile having a grid frame with a plurality of replaceable plastic tiles or tiles made of polycarbonate material. The method comprises the steps of providing a plurality of separate and replaceable tiles on a grid frame of the mosaic tile; providing an ink-jet printer having an ultraviolet stable ink; spraying the ultraviolet stable ink out from the ink-jet printer onto the plurality of replaceable tiles of the mosaic tile to form an image, and exposing an ultraviolet light on the image to cure the ultraviolet stable ink onto the plurality of replaceable tiles of the mosaic tile. The method further comprises the step of replacing an old tile with a new tile having the same marking or new markings as the old file. The method causes the ink to be embedded onto the files and remain in a very permanent state.

  • Patent number: RE37875
    Abstract: Solid objects are formed in an imagewise layering process in which components of a dispersion are homogenized to form an alloy. Imagewise exposure of the layers to radiation to form an alloy permits separation of the exposed, homogenized regions from non-exposed, non-homogenized regions. As each layer is formed and imagewise homogenized, contiguous layer regions are bonded together to form a homogenized, three-dimensional object which may be separated from surrounding dispersion.
