摘要： PURPOSE:To improve the corrosion resistance of a magnetic film by exposing a magnetic recording medium on which a protective film consisting of carbon is formed to the vapor of a high-molecular monomer in a vacuum chamber to stick and polymerize the monomer in the recesses, etc., on the surface of the protective film. CONSTITUTION:The magnetic recording medium 1 constituted by forming the thin film consisting of the carbon as the protective film 4 on the surface of the magnetic film 3 is placed in the vacuum chamber and the vapor of the high-molecular monomer evaporated in the vacuum chamber is applied onto this medium. The high-molecular monomer 7 is polymerized in the recesses on the surface of the protective film 4 consisting of the carbon and the pinholes and cracks of the protective film 4 and the magnetic film 3. The carbon particles 5 are thereby confined and the lubricity with the magnetic head is maintained by the exposed carbon film; in addition, the pinholes, etc., are embedded and the infiltration of corrosive gases into the magnetic film 3 at the time of using the magnetic recording medium is obviated. The corrosion resistance of the magnetic film 3 is thus improved.

摘要： PROBLEM TO BE SOLVED: To impart antibacterial properties onto the whole surface of a target member to which the antibacterial properties are imparted without using any antibacterial agent. SOLUTION: The antibacterial properties are imparted to the porous member by an ozone treatment after forming a synthetic resin coating film by a vapor deposition polymerization on the surface of the porous member such as ceramics. This porous member is used as the antibacterial filter for an air conditioner and an air cleaner. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a vapor deposition polymn. apparatus in which a monomer is vaporized in a vacuum and is deposited and polymerized on the surface of a substate to form a polymer film thereon and which enables an easy removal of a polymer deposited on the inner wall, etc., of a vapor deposition polymn. chamber and to provide a method for cleaning the same. SOLUTION: In the vapor deposition polymn. apparatus 1, the inner wall of a vapor deposition polymn. chamber 2 and the inside of an exhaust pipe 8 are coated with a copper plating 18, 19, and copper-made feed nozzles 5a, 5b are installed for feeding a monomer vapor; therefore, a polymer deposited on the inner wall, etc., can be removed easily. A polymer deposited can be easily removed by using a vapor deposition polymn. apparatus wherein the surfaces onto which the polymer deposits are plated with copper or wherein construction members having such surfaces have been made of copper and by introducing air into a vapor deposition polymn. chamber 2 after the completion of the vapor deposition polymn., maintaining the temp. (200 deg.C) at that time for 3hr, allowing the polymer deposited to spontaneously cool, and scratching the deposit with a cutter knife, etc.

摘要： PROBLEM TO BE SOLVED: To provide methods for forming both a polymer thin film having stable characteristics and an interlayer insulating film in a simple process. SOLUTION: A diamine and a diisocyanate as raw material monomers are evaporated in a vacuum to carry out the vapor deposition polymerization thereof on a substrate to form a low-molecular weight polyurea film, which is then irradiated with ultraviolet rays and heat-treated to perform cross-linking reaction and provide a high molecular weight. Thereby, the relative permittivity of the polyurea film is reduced. 4,4'-Diaminodiphenylmethane(MDA) is used as the diamine and 4,4'-diphenylmethane diisocyanate(MDI) is used as the diisocyanate. As a result, the relative permittivity of an interlayer insulating film 23 can be reduced to 3.08.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a light transmitting material having a thin water repellent film hardly sticking flaws. SOLUTION: A molecule having hydrophobic groups is adsorbed on a surface of a light transmitting substrate A of a plate glass or a synthetic resin plate. The molecule adsorbed is preferably a silicone compound having methyl or ethyl groups such as tetramethylcyclotetrasiloxane, octamethylcyclotetrasiloxane or heptamethyltrisloxane. The ion bombardment of the light transmitting substrate A with argon is carried out in a glow discharge in a vacuum vessel 1 and the glow discharge is then stopped to introduce a gas of a silicone compound 3 having the hydrophobic groups into the vacuum vessel 1. Thereby, an adsorbed layer of the silicone compound 3 is formed on the surface of the light transmitting substrate A.

摘要： PURPOSE:To form easily a thin film of several hundred Angstrom , and also disperse pigment uniformly by using a high polymer film having a fluorochrome structure or an oligomer film as a light emitting layer when an organic EL element is formed. CONSTITUTION:An organic EL element is composed of an anode, a hole transporting layer, a light emitting layer and a cathode. To put it concretely, the anode 2 of an ITO film, the hole transporting layer 3, the light emitting layer 4 and the cathode 5 of Mg-Ag alloy are laminated, for example, on a board 1 composed of slide glass, and prescribed voltage is impressed upon the anode 2 and the cathode 5 from electric power supply 6. In this way, though light is emitted in the light emitting layer 4, at this time, a monomer having a fluorochrome structure is used in the layer 4, and a high polymer film or an oligomer film is formed. Polyurea, polyimide, polyamide and the like are used in this, and hole transportable pigment such as a pelli-one derivative or a carbazole derivative is dispersed in this. Thereby, the element is made formable all in a dry process, and a film thickness is uniformized, and durability is improved.
