  • Patent number: 7713631
    Abstract: A ceramic paste is applied to a first glass sheet 11, and a ceramic paste is applied to a second glass sheet 13 with a lower solar absorptivity than that of the first glass sheet 11. In this case, the amount per unit area of the ceramic paste to be applied to the first glass sheet 11 is allowed to be smaller than that of the ceramic paste to be applied to the second glass sheet 13. Alternatively, a first ceramic paste and a second ceramic paste are allowed to have different compositions from each other. The first glass sheet 11 and the second glass sheet 13 are bent so that the surfaces onto which the ceramic pastes have been applied are shaped as concave surfaces. The applied ceramic paste is fired using the heating used for bending. Thus maskings 12 and 14 are formed. The first glass sheet 11 and the second glass sheet 13 are bonded to each other, with a resin interlayer film 15 being interposed therebetween.

  • Publication number: 20090302681
    Abstract: A power supply system capable of smoothing photovoltaic generation output, and enabling time shift is provided. A power supply system including a DC power supply string in which a storage battery is connected in parallel to a DC power supply; and a DC/AC power conversion device for connecting the DC power supply string to a power system or a load is provided. A switch is connected between the DC power supply and the storage battery, where an output power of the DC power supply or a combined output power of the DC power supply and the storage battery is switched and supplied to the DC/AC power conversion device by the switch. The photovoltaic generation output is thereby smoothed, and time shift is enabled.

    Abstract: A lithium secondary battery which comprises: a negative electrode comprising as an active material a carbonaceous material capable of electrochemically holding/releasing lithium; a positive electrode comprising as an active material a lithium chalcogenide; and polymer electrolyte layers united respectively with the negative electrode and the positive electrode. The polymer electrolyte layers comprise an ionically conductive polymer matrix holding a nonaqueous electrolytic solution. They are obtained by crosslinking and polymerizing a liquid mixture of a monomeric precursor for the ionically conductive polymer and the nonaqueous electrolytic solution respectively on the negative electrode and the positive electrode using different polymerization initiators.

  • Publication number: 20090257141
    Abstract: A bent glass sheet (1) with a light-shielding film for vehicles includes a glass sheet, and a light-shielding film formed in at least a part, i.e. a film-formed portion (11), of a peripheral portion of one surface of the glass sheet. The light-shielding film is composed of a band-shaped film (12) and a dot-patterned film (13). The band-shaped film is arranged in an outer part of the peripheral portion. The dot-patterned film composed of a plurality of dots (14) is arranged in an inner part with reference to the band-shaped film. The plurality of dots are positioned so that a distribution of the dot shielding ratios decreases from the edge of the band-shaped film toward a side of a glass surface (a non-film-formed portion (15)) on which the band-shaped film is not formed, where the dot shielding ratios are values of peaks of mountains formed of a distribution of the dot-width shielding ratios, or dot-diameter shielding ratios.

  • Publication number: 20090151604
    Abstract: A cement additive contains industrial waste and has the effect of inhibiting formation of monosulfate in a hardened cementitious material. The cement additive contains specifically calcium carbonate, gypsum and coal ash and/or blast-furnace slag powder. This enables efficient use of industrial waste, allows inhibiting monosulfate formation in the hardened cementitious material, and allows producing a hardened cementitious material having good durability (sulfate resistance).

  • Patent number: 7514654
    Abstract: The present invention is intended to provide a glass article with a metal member joined thereto in which an electroconductive coating film is formed on at least a part of the surface of the glass article by baking a silver paste that includes Ag particles and a glass frit, a joining plane of the metal member is fixed onto the electroconductive coating film with a lead-free solder alloy containing Sn as a main component, and the lead-free solder alloy contains at least 1.5 mass % of Ag, which prevents the appearance of the electroconductive coating film and the bonding strength from degrading. Furthermore, in the present invention, when using a metal member having at least two joining planes, the total area of the joining planes is set within a range of 37 mm2 to 50 mm2, which allows high bonding strength between the glass article and metal member to be maintained while using the lead-free solder alloy.
