Abstract:
A highly transparent, colorless anti-reflection film and a plastic substrate with the anti-reflection layer that offers superior productivity. Furthermore, an anti-reflection film and a plastic substrate with the anti-reflection layer offering superior optical characteristics and resistance to moisture and gases. An anti-reflection film is made of a hard-coat layer formed on a substrate and transparent, high index of refraction oxide layers and transparent, low index of refraction oxide layers laminated on top of each other on the hard-coat layer. The transparent, high index of refraction oxide layers comprises Nb2O5 layers formed by a reactive ion sputtering method. Furthermore, in the anti-reflection film using a substrate composed of an organic material, an inorganic moisture barrier layer, having an index of refraction similar to the organic material, is formed in contact with one side of the substrate.

A thin film magnetic head has a lower magnetic layer (2) and an upper magnetic layer (3) formed over the lower magnetic layer (2) so that a small gap (FG) is formed between a magnetic gap section (Dp) of the lower magnetic layer (2) near a sliding surface to be brought into sliding contact with a magnetic recording medium and a magnetic gap section (3a) of the upper magnetic layer (3) extending in parallel to the magnetic gap section of the lower magnetic layer near the sliding surface. The the upper magnetic layer has a first sloping section (3b) extending from the magnetic gap section at an inclination theta 1 in a range defined by 2 DEG

PROBLEM TO BE SOLVED: To provide a reflection type screen in which the contrast of a display image is high and a variation in white balance is less. SOLUTION: The reflection type screen 10 comprises by bonding together in the following order: a light reflection layer 11 having substantially uniform reflectance in at least a visible wavelength region; a light absorption layer 12 absorbing part of transmitting light; and a light diffusion layer 13. The reflection type screen 10 displays an image by reflecting projection light from a projector, in which the light absorption layer 12 has such a light absorption characteristic that the absorption factor of a green wavelength region is greater than those of blue and red wavelength regions.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing a magnetic recording medium, capable of achieving high-density recording by smoothing a recording medium and reducing a spacing loss, and reducing image defects by the deterioration of an error rate caused by an abnormal projection, and the magnetic recording medium. SOLUTION: An abnormal projection formed on the surface of a magnetic layer is removed by forming a protective film by a CVD method after a magnetic layer is polished, and the surface of the magnetic recording medium after the formation of the protective film is smoothed. The polishing of the magnetic layer and the formation of the protective film are executed in the same vacuum vessel. When the magnetic layer is polished, a tape-shaped polishing tape abuts on the magnetic layer-formed surface of a nonmagnetic support, and the nonmagnetic support and the polishing tape are slid relatively to each other. The formation of the protective film is executed by a plasma CVD, and the carbon of a diamond structure is contained in the protective film. Preferably, the thickness range of the protective film is 2 nm to 14 nm. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To solve problems such as power reduction, drop-outs in the reproduction output of a magnetic recording and reproducing device which performs magnetic recording and/or reproduction due to the dust sloughing off or moving from another part (which is called a slough powder). SOLUTION: The device is provided with a cleaning mechanism 2 which scrapes the sticking powder on a magnetic recording medium. The cleaning mechanism 2 consists of a cleaning roller Rc which is brought into contact with a magnetic head and is separated from the head and a scraping blade B, and the blade B is constituted so that the ridgeline of the edge of the blade is extended in the axial direction of the roller Rc and the edge can slide along the periphery of the roller by the rotation of the roller. Thus, the slough powder on the magnetic layer of the magnetic recording medium which is moved from the magnetic head and stuck to the roller is scraped off by the blade and the power is prevented from moving from the cleaning roller and sticking to the magnetic head again.

PROBLEM TO BE SOLVED: To solve the problem that a long time is required in the cleaning work for cleaning a reaction tube in a plasma enhanced CVD system. SOLUTION: The reaction tube 9, in which a plasma opening toward an arrange part for arranging a work to be film-deposited is generated, is constructed as a separate structure constituted of an outer housing 91 and a cylindrical inner wall body 92 detachably inserted into the outer housing 91 so as to be disassembled into a plurality of parts, in a vacuum chamber. Thereby, the cleaning of the reaction tube 9 can be carried out by cleaning the cylindrical inner wall body 92 having a simple structure. Accordingly, the cleaning can be surely and easily carried out, and the working efficiency is improved, and further the yield of products by the film deposition is enhanced. COPYRIGHT: (C)2004,JPO
