  • Patent number: 6342121
    Abstract: Disclosed is a method of accurately, simply forming a light absorbing layer for improving contrast in a transmission screen including micro glass beads two-dimensionally arranged. A light absorbing layer made from toner is formed on glass beads held in a transparent adhesive layer up to a thickness sufficient to cover the glass beads. The light absorbing layer is irradiated with parallel rays of light in the direction from a transparent substrate, to melt and remove only a portion of the light absorbing layer positioned over a light outgoing portion of each glass bead by the energy of the rays of light converged through the glass bead. By suitably selecting a material of the light absorbing layer, openings can be formed in the light absorbing layer by means of combustion, sublimation or ablation due to the energy of the converged rays of light.

  • Patent number: 6342122
    Abstract: An solvent-based pressure sensitive adhesive (PSA) having improved shear adhesion is composed of an acrylic-based PSA resin, an ethylenically unsaturated polyester, an ultraviolet radiation (UV) photosensitizer, and fugative organic solvent for the acrylic-based PSA resin. The PSA is cured by evaporation of the fugative organic solvent coupled with heat and UV irradiation or UV irradiation alone. Such PSA has improved shear adhesion by dint of the addition of the ethylenically-unsaturated polyester and an ultraviolet radiation (UV) photosensitizer. A method for adhering two substrates using the PSA includes applying the PSA to one or both of substrates. The solvent in the PSA is evaporated from the applied PSA. Finally, the polyester component of the applied PSA is cured by exposure of the applied PSA to ultraviolet (UV) radiation.

A new magnet block is transported by sliding on the upper surface of the plate yoke, and is bonded side by side with the projection or a magnet block which is already fixed. During the above operation, a magnetic member is held above the plate yoke. Preferably, the new magnet block is transported toward a corner portion, with side surfaces of the magnet block held parallel to a side surface of the projection and a side surface of the guiding rail respectively. When the magnet unit and the column yoke is connected, the column yoke or the magnet unit is lowered so that a guiding rod attached to an end face of the column yoke is inserted into a hole formed in the magnetic unit. Further, the column yoke is guided by a guiding member disposed between a permanent magnet on the plate yoke and a position where the column yoke is to be connected on the plate yoke.

  • Patent number: 6334925
    Abstract: The present invention relates to a method for bonding together two disc substrates, at least one disc substrate having a UV transmissive-visible light reflective information recording layer provided on a UV transmission base. In this method, the disc substrates are bonded together, so that the information recording layer of one disc substrate faces the other disc substrate, by employing UV irradiation to cure a UV curable composition used as a bonding agent. In the case of the present invention, to cure the bonding agent, UV is irradiated in a single or repeating flash so as not to impair the information recording layer. As a result, the bonding agent can be cured in a shorter period of time with less energy consumed as compared to the conventional method of using conditions irradiation of UV light to cure a UV curable composition used as a bonding agent. Accordingly, the present method enables a product disc to be obtained in a shorter time, with less energy used, so that productivity (i.e.

  • Patent number: 6251211
    Abstract: Electrically conductive polymer bumps are formed in electrical connection with circuitry supported by a first substrate. The polymer bumps are bonded with a conductive adhesive to circuitry supported by a second substrate, with the conductive adhesive being in electrical connection with the circuitry supported by the second substrate. Prior to said bonding, an effective amount of ultraviolet radiation is impinged onto the polymer bumps to enhance adhesion of the bumps with the conductive adhesive and electrical conduction between the circuitry of the first substrate and the circuitry of the second substrate. In one implementation, ultraviolet radiation of at least 340 nm is impinged onto conductive polymer bumps prior to subsequent bonding. In one implementation, ultraviolet radiation is impinged onto conductive polymer bumps for a time period less than one minute prior to subsequent bonding.

  • Patent number: 6251202
    Abstract: A method and system for bonding plastic parts together utilizing a heat-activated adhesive and at least one infrared lamp are disclosed. The system preferably includes first and second infrared lamps for emitting infrared radiation. A first base section supports a first infrared lamp adjacent the first plastic part and a second base section supports the second infrared lamp adjacent the second plastic part. The system also includes a controller coupled to the first and second infrared lamps for controlling power supplied to the first and second infrared lamps so that the first infrared lamp emits infrared radiation which propagates through the first plastic part and is absorbed by the adhesive and the second infrared lamp emits infrared radiation which propagates through the second plastic part and is absorbed by the adhesive for a time sufficient to heat the adhesive to a desired temperature at which the adhesive is activated. The activated adhesive bonds the plastic parts together.
