摘要： PURPOSE:To provide a method for producing a thin org. polymer film useful as a surface protection film, a nonlinear optical film, a liq. crystal orientation film, a separating film, etc. CONSTITUTION:A thin org. polymer film is produced by introducing at least two polymerizable monomers into a vacuum container and causing vapor deposition and polymn. simultaneously on a substrate in the container in such a way that a carrier gas is passed at a specified flow rate through each of the polymerizable monomers kept at a specified temp. in a tightly sealed container and the carrier gas contg. the monomer is introduced into the vacuum container. Since the amt. of the monomer evaporated can be accurately controlled by controlling the flow rate of the carrier gas regardless of whether the monomer is solid or liq., the film with a higher purity is produced.

摘要： PROBLEM TO BE SOLVED: To provide a recyclable resin-ceramic powder composite material hardly causing changes in the dielectric constant of a product and therefore in electric properties of an electric part even when processed under a condition such that a relatively large shear force is exerted as in the case of injection molding or extrusion molding, and to provide an antenna and an electric appliance obtained by using the resin-ceramic powder composite material. SOLUTION: In the resin-ceramic powder composite material, the ceramic powder is composed of a dielectric ceramic having an average particle size of at most 3 μm. The antenna and the electric appliances are obtained by using the resin-ceramic powder composite material. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To reduce misreading of information and to make it difficult to forge it by partially breaking and optically parting a light guide of the information card which is sandwiched between covers and has light guides that are optically parted when necessary, and recording the information by an array of the light guides. SOLUTION: When the information card 10 is pressed on the top surface to partially break a light guide, the pressed part itself of the information card 10 becomes thin and the light guide deforms to become thin or is structurally parted when a relatively soft material is used. Therefore, when the information card 10 is pressed sufficiently, the light guide can optically be parted to
