  • Patent number: 8598405
    Abstract: An object of the present invention is to provide a waste solution solidifying agent which can solidify a waste solution, particularly, a waste solution containing blood or body fluid at a low cost, uniformly, and in a short time; in particular, to provide a waste solution solidifying agent which can solidify a waste solution uniformly and in a short time in a vertically oriented waste solution equipment. As a means of achieving this object, a waste solution solidifying agent of the present invention is a particulate treating agent used in a method of treating a waste solution which solidifies a waste solution into a gel by placing a treating agent in a waste solution, and is characterized in that said agent contains, as an essential component, a water-absorbent resin having a crosslinked structure obtained by polymerizing a water-soluble ethylenic unsaturated monomer and, when flowing-placed at once into a 0.

  • Patent number: 8394504
    Abstract: Disclosed is an optical planar thermoplastic resin composition including a lactone ring-containing polymer as a main component thereof, or including a lactone ring-containing polymer and at least one other thermoplastic resin. The optical planar thermoplastic resin composition of the present invention has high transparency, high heat resistance, and high optical isotropy, and therefore, can sufficiently exhibit characteristics according to various optical applications.

  • Publication number: 20090081469
    Abstract: The present invention provides a pressure-sensitive adhesive composition containing a near infrared ray absorption agent excellent in heat resistance and hygrothermal resistance while maintaining sufficient NIR shield characteristics and transparency. The problem can be solved with a pressure-sensitive adhesive composition, comprising: (I) at least one kind selected from phthalocyanine-based compound and naphthalocyanine-based compound having maximum absorption wavelength in a region from 800 to 920 nm, as near infrared ray absorption agents; (II) at least one kind selected from phthalocyanine-based compound and naphthalocyanine-based compound having maximum absorption wavelength in a region over 920 nm as near infrared ray absorption agents; and a pressure-sensitive adhesive resin having an acid value not higher than 25.

  • Patent number: 5676901
    Abstract: Consequently, the resin molding can be coated over the whole surface with a coating material uniformly and with an excellent adhesion.A molding material is compressed and molded with a mold comprising split molds and capable of forming a space between them outer periphery and slidable position of which are tapered, the molds are mutually separated before complete curing to define a space between at least one side surface of the molding and an opposing surface of the mold, a gas flow is formed inside the molds and in a direction towards the outer periphery for discharging any foreign material such as molding-flash and dust through the space to the exterior of the molds, and a fluid coating material is injected in the space between the molding and the surface of the mold and, with the molds clamped again, compressed to be cured.
