Abstract: A transparent laminate useful as an optical filter having an excellent anti-reflection property, a near-infrared ray absorption property, an electromagnetic wave-shielding property, durability, visibility and reduced weight. The transparent laminate comprises a first laminate portion including a first transparent substrate, an anti-reflection layer and a near infrared ray-absorption layer respectively formed on the front and back surfaces thereof; and a second laminate portion including a second transparent substrate and an electromagnetic wave-shielding layer formed on one surface thereof. The first transparent substrate and the second transparent substrate are integrally jointed together; i.e., the near infrared ray-absorption layer and the electromagnetic wave-shielding layer or a metal mesh layer are integrally joined together via an adhesive layer.

Abstract: The present invention provides an anti-bacterial and anti-fungal glaze composition for ceramic products formed by incorporating a silver-containing substance; and a fire resistant material and/or glass composition. The present invention can be used in the manufacture of ceramic products requiring sanitary properties such as tile, sanitary earthenware, commodes, bath tubs and the like, and according to the present invention, anti-bacterial and anti-fungal properties can be effectively exhibited therein. In particular, the present invention can be used in sink basins, tile, commodes, bath tubs, and the like of hospitals, hotels and public facilities.

Abstract: There is provided a structure of artificial bone for use in implanting or grafting bone comprising; a sintered body of calcium phosphate compounds; and hollowed minute tubes in said sintered body, having very small diameter, and extending along with a direction of Haversian canal extension of live organism, so as to produce two dimensional close-packed structure in said body, in form of cubic or hexagonal arrangement. The arrangement has in the sintered body of calcium phosphate compounds; hollowed minute tubes having a diameter of 0.1 to 2.0 mm, and the major portions thereof extending along with a direction of the Haversian canal extension, and producing a two dimensional close packed arrangement in said body against the face vertical to said direction, and being arranged with a separation, distance of 1.0 to 5.0 mm. The structure has preferably really spherical pores having diameter of 50 to 600 micrometer, and the porosity thereof being 0.5 to 40 percent.
