  • Publication number: 20030087079
    Abstract: An object of the present invention is to provide polyolefin resin composite laminates prepared only from polyolefin resin materials which are environmentally friendly and flexible, the laminates being lightweight, having high rigidity, remaining free of decay, showing no dimensional variations if subjected to temperature or humidity variations and being amenable to recycling. A polyolefin resin is reacted with a modifying monomer to modify the resin. A chemical blowing agent is added to the modified resin obtained, followed by kneading. The resulting expandable resin composition is shaped into a sheet. A facing material is laminated to one surface of the expandable sheet obtained, the facing material having a strength capable of inhibiting the sheet from expanding in in-plane directions when the sheet is heated for expansion. The expandable sheet is heated for expansion to obtain a polyolefin resin composite laminate.

  • Patent number: 5676998
    Abstract: A thin film magnet and a cylindrical ferromagnetic thin film having a high maximum energy product (greater than 120 kJ/m.sup.3) and thus suitable for use in miniature high performance devices are provided. The thin film magnet is produced by means of physical vapor deposition. The thin film magnet is an (Nd.sub.1-x R.sub.x).sub.y M.sub.1-y-z B.sub.z alloy having a ferromagnetic compound of the Nd.sub.2 Fe.sub.14 B type as its main phase, wherein R is Tb, Ho, and Dy and M is Fe metal or an Fe-based alloy including at least one of Co and Ni, 0.04.ltoreq.x.ltoreq.0.10,0.11.ltoreq.y.ltoreq.0.15, and 0.08.ltoreq.z.ltoreq.0.15. A perpendicular magnetization film having such a composition is deposited on the side wall of a substrate in the columnar (or cylindrical) form thereby obtaining a cylindrical ferromagnetic thin film having radial anisotropy.
