  • Patent number: 8367210
    Abstract: The invention provides the advantages of a metallic housing and those of a synthetic resin structure for electronic devices, home electrical devices, etc., achieves high productivity and mass productivity, and enables a desired configuration and structure to be designed freely. As a pretreatment, a shaped aluminum alloy material is dipped in an aqueous solution of at least one selected from the group consisting of ammonia, hydrazine, and a water-soluble amine compound. A thermoplastic resin composition containing polyphenylene sulfide as a component is integrally bonded to the surface of the treated shaped aluminum alloy material by injection molding or other method. The molded article is a product made of the shaped aluminum alloy material and the thermoplastic resin composition containing PPS. Thus, the characteristic features of metal can be utilized in terms of mechanical strength and external appearance design. Moreover, a complicated configuration and structure can be formed inside the housing.

  • Patent number: 8334044
    Abstract: A hydrogel-metal assembly is provided. An intervening polymer network is used to bond together a water-swollen hydrogel layer and a biocompatible surface-modified metallic layer. The hydrogel layer is a water-swollen hydrogel layer of at least two interpenetrating polymers. The surface of the biocompatible surface-modified metallic layer is surface-modified with an inorganic material. The intervening polymer network has been chemically grafted to the inorganic material of the biocompatible surface-modified metallic layer through bi-functional linker molecules. The intervening polymer network is further physically or chemically cross-linked with the polymers of the water-swollen hydrogel. The hydrogel-metal assembly can be adapted to form a medical device, medical implant, an artificial implant, an orthopedic implant, or at least as part of a joint.

  • Patent number: 8323799
    Abstract: Soft, flexible highly lubricious coatings for polymeric IOL insertion cartridges that allow IOLs to be easily inserted through small bore cartridges suitable for use with small (less than 3 mm) incisions are provided. These lubricious coatings allow IOLs to be inserted into the eye of a patient without the risk of lens damage or transfer of lubricants to the lens surface during implantation. Specifically, polymeric coatings comprising a matrix polymer having an equivalent weight greater than 5000 g/eq are used to form interpenetrating networks (IPN) on the surface of hydrophobic structural polymers. The IPNs thus formed entrap highly lubricious hydrophilic compounds within the IPN using multi-functional cross linkers.
