  • Publication number: 20240081867
    Abstract: Provided is a fixture rod that is excellent in bonding strength between a core material and a reinforcing fiber layer and has high rigidity and high durability against a deformation load. A fixture rod according to one embodiment of the present disclosure comprises: a core member containing a resin; and a reinforcing fiber layer provided on the core member, and is configured such that the resin of the core member and a resin of the reinforcing fiber layer are the same resin, or the resin of the core member and the resin of the reinforcing fiber layer are different resins, and a critical surface tension of each of the resin of the core member and the resin of the reinforcing fiber layer is 20 mN/m or more.

  • Publication number: 20090091122
    Abstract: The present invention provides a personal information protecting sheet in which personal information can be easily made illegible. The personal information protecting sheet includes a base material, a release layer formed on at least a part of the surface of the base material, and an image-receiving layer formed on the release layer. When a force having a directional component that is larger than a predetermined value and parallel to the surface of the base material is applied to the surface, a portion of the image-receiving layer to which the force is applied is peeled from the release layer.

  • Publication number: 20050113738
    Abstract: There is provided an electrode device for iontophoresis capable of retaining a drug in a gel state with a force just enough so as not to disturb the treatment. In order to retain the gel (70), a sheet member (50) composed of a nonwoven fabric is laminated on a base film (20) including an electrode layer (30) so as to be integrated with the base film (20). The sheet member (50) has a property for allowing the gel (70) to permeate therein. Owing to this feature, the gel (70) loaded on the sheet member (50) is retained thereon with at least a part of the gel (70) permeated therein.

  • Patent number: 6150004
    Abstract: An antimicrobial laminate excelling in the ability to effect gradual release of an antimicrobial agent and providing an antimicrobial action evenly and bags and other containers using the antimicrobial laminate are disclosed. A substratal film 24 impervious to steam is provided on one side of a substratal film proper 22 of paper with a gas-barriering layer 23 of aluminum foil. An antimicrobial film 21a pervious to steam is formed by sequentially superposing an adhesive agent layer (AITC regenerating layer) 16a containing an AITC inclusion cyclodextrin compound 15 (fine powder), a steam-pervious film 17a having a fine powder of silica gel dispersed therein, an adhesive agent layer 16b identical in construction with the adhesive agent layer 16a, and a sealant material 17b of steam-pervious film in the order mentioned. An antimicrobial layer 121 is constructed by adhesively superposing the substratal film 24 and the antimicrobial film 21a through the medium of the adhesive agent layer 16a.
