摘要： PURPOSE:To falitate the disposal, and make the recycling possible by using a foamed polystyrene film as the raw material. CONSTITUTION:For a press through pack 1, a tablet M such as medicine, etc., is stored in each depressed part 2 on a bottom member 3 on which a plurality of independent depressed parts 2 for storage of a content are shaped, and under that condition, a lid member 4 for press through pack is put on the top, and the lid member 4 and the flat part of the bottom member 3 other than depressed parts are sealed by heat-bonding. In this case, as the lid member 4, a foamed polystyrene film is used, and preferably, a heat-sealing layer 5 is provided on one surface of the lid member 4. When the press through pack 1 utilizing such a lid member 4 is pressed from the bottom member 3 side, the lid member 4 is easily broken by the tablet M, etc., the content, and the taking out of the content in the packaging body can be easily done. Also, since the lid member 4 leaves no residue at the time of incineration, the disposal is easy, and the recycling as a plastic raw material becomes possible.

摘要： PURPOSE:To make visual recognition of information stored in a card easy by a method wherein a liquid and magnetic powder afloat in the liquid and sensitive to a magnetic field are contained in microcapsules arranged in a recording layer laid by coating on a base of a magnetic display section. CONSTITUTION:An information storage section 4 and a magnetic diaplay section 10 are laid on a base of a prepaid card. The information storage section 4 is made up of a magnetic tape or an IC memory, and the magnetic display section 10 has a base and a recording layer containing microcapsules that is laid by coating directly, or through an intermediate layer, on the base. A liquid and magnetic powder that is afloat in the liquid and sensitive to a magnetic field are contained in the microcapsules. The information is recorded, in accordance with the information stored in the information storage section 4, in a visible form on the recording layer of the magnetic display section 10, and is erased from the layer.

摘要： PURPOSE:To obtain a mold release sheet which is capable of using at a molding temperature of at least about 200 deg.C, by forming a cured resin film comprised of curable phosphazene compound on the surface of a base sheet. CONSTITUTION:A coating layer of a coating agent consisting mainly of a curable phosphazene compound is formed on the surface of a base sheet. Then the curable phosphazene compound in the coating layer is polymerized partly. Embossing processing is performed to a coating layer surface under this state, the curable phosphazene compound in the coating layer is polymerized completely further and a desired mold release sheet is obtained.

摘要： PURPOSE:To perform a good finish-polishing so that a substrate develops the cushioning ability and other various performances intended for use during the time of using a polishing tape by forming the substrate by two or more types of films having different physical properties. CONSTITUTION:A substrate for a polishing tape used for polishing magnetic heads, magnetic discs, optical fiber end faces is formed by two or more types of films having different physical properties. As a result, the substrate develops the cushioning ability and other various performances (mechanical strength, dimensional stability, heat-resisting property and the like) intended for use during the time of using the polishing tape. When a work is finish-polished with the polishing tape held closely in contact with the work, an excessive pressure applied to the polishing tape can thus be absorbed by the cushioning ability of the substrate, and the work can be favorably polished and finished.

摘要： PURPOSE:To improve the dispersion performance and stability of the inorganic fine powder in coating agent by forming the polishing agent particle made of the composition which forms the polishing layer of a polishing tape, into the inorganic fine powder whose surface is hydrophobic-treated. CONSTITUTION:The inorganic fine powder such as silica which is used as polishing grains is heat-treated at a temperature of 150-200 deg.C, and after the physically adsorbed water on the surface is removed, said fine powder is immediately dispersed into the organic solvent such as isopropyl alcohol, and further the surface hydrophobic treating agent such as trimethylcholorosilane is added, and after the heating and stirring, the solvent is filtered, and the powder is dried and hydrophobic-treated. The inorganic fine powder, binder consisting of polyester group resin, and the mixed solvent consisting of toluene and methyl ethyel ketone are kneaded, and the obtained coating agent is applied onto a thermoplastic polyester film and dried, and then a polishing tape is obtained. Thus, the dispersion and stability of the inorganic fine powder can be improved, and a uniform polishing layer can be obtained.

摘要： PURPOSE:To eliminate the inclusion of bubbles and obtain a smooth surface and god appearance by forming a polishing layer with polishing grains made of specific resineous film coated inorganic fine powder filled in a resineous layer soluble in an non-alcoholic solvent. CONSTITUTION:In the floating field of resineous liquid fine grains dissolved in a solvent of alcoholic system, air flows containing inorganic fine grains are made to collide with each other at extra-high speed, thereby cracking and crushing an aggregate of inorganic fine powder and coating inorganic fine powder with a resin soluble in an alcoholic solvent after further cracking and crushing in a coating chamber 1 for the formation of polishing grains. The polishing grains so formed are dispersed in a resineous liquid made from a resin soluble in an non-alcoholic solvent dissolved in a non-alcoholic solvent and a resineous solution containing dispersed polishing grains is obtained. Then, the resineous solution is applied to the base material of a polishing tape without any inclusion of bubbles and dried to form a polishing layer.
