Abstract: A drink pack position-keeping device of the present invention keeps a drink pack in a drink container at the reasonable location and the drink pack can easily be taken out from the drink container any time. The drink pack position-keeping device of the present invention comprises a stopper, a suspending unit and an attaching unit. The drink pack containing an object to be infiltrated is attached to the suspending unit with the attaching unit. When the drink pack position-keeping device is attached to the drink container, the stopper is placed on the entire rim of the upper end of the mouth of the drink container, and the drink pack suspending from the stopper is located at the predetermined length lower than the liquid level in the drink container. Accordingly, the drink pack is prevented from going to the bottom of the drink container.

Abstract: This invention provides the following: an amphiphilic functional substance with lipophilicity, affinity for supercritical CO2, and if necessary hydrophilicity comprising an oligoolefin chain and a perfluoroalkyl group(s) at a single end thereof or at both ends thereof with or without the intervention of a poly(oxyalkylene) chain, which enables the utilization of supercritical CO2 as a reaction medium; a photopolymerizable functional substance comprising an oligoolefin chain and a reversible photopolymerization/dissociation group(s) at a single end thereof or at both ends thereof and a functional substance comprising a photo- and/or thermodissociable polymer obtained by photopolymerization of the aforementioned photopolymerizable functional substance, which can be utilized as recycle polymers; a hydrolyzable functional substance comprising a polymer obtained by chain-elongating plural oligoolefin chains through ester linkages, which can be utilized as a recycle polymer; and a functional substance capable of fo

Abstract: A resin composition of the present invention comprises a polymer having functional groups and a metal oxide surface modified to form functional groups at a surface of the metal oxide and dispersed uniformly in the polymer. The functional groups of the polymer and the functional groups of the metal oxide are ionically bondable to the metal oxide and the polymer, respectively, so that the polymer and the metal oxide are bonded by ionic bonds to each other.

Abstract: For producing a modified silica composition, finely particulate silica with silanol groups is used. The finely particulate silica is so modified as to have a modification factor of 0.45 to 8 as expressed by the product (A×B) of the hydrophobic ratio (A) of its silanol groups and the total carbon number (B) of alkyl groups. It makes with a matrix resin a transparent resin composition of high transparency and rigidity which can make a thermoplastic resin laminate having an excellent appearance and suitable for application to a part for the exterior decoration of a vehicle.

Abstract: A resin composition to be used as a material of a part of an automotive vehicle. The resin composition comprises a matrix resin. Linkages of inorganic fine particles are uniformly dispersed in the matrix resin. Each linkage has hydroxyl groups and hydrophobic groups which are introduced by a hydrophobicity-providing treatment. The linkages take at least one of a chain-like form and a net-like form.

Abstract: A resin composition to be used as a material for a various part of an automotive vehicle. The resin composition comprises a copolymer (A) formed by copolymerization of a first unsaturated monomer (a) and a second mononer (b). The first unsaturated monomer has a functional group which is bondable by hydrogen bond to a hydroxyl group. The second monomer is copolymerizable with the first unsaturated monomer. A metal oxide (B) is dispersed in the copolymer and having hydroxyl groups and hydrophobic groups at surface of the metal oxide.

Abstract: The configuration procedure for an access code and for a security code is provided, comprising: providing references retaining element file that records the base checkerboard-like substrate, checkerboard-like substrates and the color substrates as a graphical image with a hierarchical layered structure arranged on the base substrate, assigning the digital elements to both the x- and the y-axes of the base substrate, assigning the digital elements assigned to the references retaining element on the base substrate perpendicular to the selected two retaining element to the selected two retaining element of the checkerboard-like substrate, configuring code based on the assigned digital elements and the prescribed priority order of the first and areal codes and at the time of the code configuration, recording the location of the retaining element, coaxially rotating the checkerboard-like substrates and color substrates with respect to base checkerboard-like substrate, whereby a new code is configured based on the

Abstract: A stereo code which can display a large amount of information on a small area without impairing the beauties of the goods etc.

Abstract: In a computer system for playing a computer game of the present invention, the computer game is a competing type game and specific characteristic data of each of game players is stored in a memory card of each game player. The specific characteristic data is removable from one memory to another memory in accordance with result of the competing game. The memory card is detachable from the computer system. Further, the computer system is able to be connected with a network. Therefore, a skill of the game player is displayed and stored clearly and correctly. Further, each skill of the game players is displayed on all display units of the game players at same time on the network.

Abstract: There is disclosed a method for the preparation of a copolymer of polypropylene and organopolysiloxane, the method comprising heating a solution of an .alpha., .omega.-diene-propylene polymer and an organohydrido polysiloxane having on average at least two SiH groups in one molecule at a temperature below the boiling point of the solvent. Preferably, the .alpha., .omega.-diene-propylene polymer is obtained by subjecting polypropylene to thermal decomposition in an inert atmosphere at a pressure below atmospheric pressure.
