Inside the casing, the desiccant extracts airborne water vapor. The two-stage removal of odor-causing constituents and water vapor rapidly and effectively extracts moisture and odors. The silica gel and activated carbon are porous and have high surface areas available for adsorption, whereby the insert is adapted to maintain moisture and odors at low levels during long-term storage.

  • Patent number: 7622199
    Abstract: A thin-profile organic EL device with a high degree of reliability is provided. The anode, the organic layer and the light transmissible-type cathode are laminated on the substrate and the inorganic water-barrier layer are laminated thereon, and then a UV rays-curable type water-capturing agent comprising a UV rays-curing agent and a water-absorbing agent is cured to bond to the sealing substrate instead of an adhesive layer. The UV rays-curing agent comprises an acrylic monomer, initiator and accelerator. The UV rays-curable type sealing agent is placed to the outer peripheral portion of the UV rays-curable type water-capturing agent to be cured. The emission of the organic layer is transmitted upward via the cathode, UV rays-curable type water-capturing agent and the sealing substrate.

  • Publication number: 20090242833
    Abstract: Disclosed are soil additives comprised of self-situating, stimuli-responsive polymer compositions and methods of their use. In one embodiment, the polymer composition or polymer network comprises permanent cross-links and non-permanent cross-links, wherein the non-permanent cross-links are capable of being removed upon application or exposure to a stimulus, typically located within the soil. In another embodiment, the method of increasing water retention in soils includes applying a soil additive, comprising polymer networks of the present invention admixed with an aqueous solution to form a colloidal dispersion solution or suspension, to a soil surface. The suspension or colloidal dispersion solution facilitates penetration of the polymer composition through the soil surface and into the soil, migrating typically to lower water potential areas and, more typically, along drainage channels located within the soil.

  • Patent number: 7521864
    Abstract: An electron device such as a fluorescent display tube is provided, wherein a simple ring-less getter can be simply fixed and arranged with a large degree of freedom. The ring-less getter is securely fixed to the inner surface of the glass anode substrate using laser beams. The laser beam is irradiated onto the ring-less getter from outside the anode substrate. Thus, the laser beam passes through the anode substrate thus heating and melting the ring-less getter. The corresponding inner surface of the anode substrate is melted through the heating. In cooling, the portion where the ring-less getter and the anode substrate are in a molten state is solidified, so that the ring-less getter is bonded to the anode substrate. The ring-less getter is shaped arbitrarily through press-working a getter material.
