摘要： PURPOSE: To make it possible to form a thick coating layer with one time of stage and to form finer partitions by molding a coating liquid contg. a material forming partitions with a molding material and parting the moldings from molds after curing at the time of forming the partitions on a substrate surface. CONSTITUTION: The coating liquid 21 consisting essentially of fine powder of low melting glass contg. an adhesive is applied on the mold material 3 and a coating liquid layer is formed on the mold material 3. The excess coating liquid 21 built up on the surface of the mold material 3 is then scraped off by a scraper to flatten the surface of the mold material 3. Next, the glass substrate 1 is placed on the mold material 3 and the entire part is inverted to bring the side formed with the recessed parts of the mold material 3 into tight contact with the glass substrate 1. After the coating liquid 21 is cured, the mold material 3 is peeled from the glass substrate 1. Finally, the partitions 22 consisting of the cured coating liquid is calcined to form the glassy partitions. The partitions suitable for a plasma display device or a liquid crystal display device executing scanning by a plasma discharge are formed.

摘要： PURPOSE: To reduce a partitioning wall forming cost to fine the partitioning wall width, by constituting a partitioning wall layer, formed on a glass base board, of the sintered body of a thin plate state glass fine particle. CONSTITUTION: The partitioning wall 2 of a fine particle, composed of thin plate state glass having a thickness of 2μm or thinner, is formed on a glass base board 1. Coating liquid, prepared by blending photosensitive resin and an organic solvent, is applied to a thin plate state glass fine particle to be dried. Ultraviolet light 6 is irradiated to the glass base board 1 via a photomask 5 to make the photosensitive resin be sensitized. A resultant is developed to remove an unnecessary part to be baked and sintered, thereby obtaining a partitioning wall forming glass plate. When a thin plate state glass fine particle is used as a glass fine particle in the coating liquid, since the glass fine particle is arranged in a direction parallel to the base board 1 at the time of coating, the ultraviolet light becomes difficult to be expanded in a direction other than an irradiation part in an exposure process, and the attenuation of the ultraviolet light is reduced in a thickness direction, thereby a fine partitioning wall, having high height and narrow width, can be formed.

摘要： PURPOSE:To remarkably reduce the load fluctuation at the time of grinding, extremely reduce dressing, and improve the availability factor by flattening the tip sections of exposed abrasive grains, and specifying the concentration of the abrasive grains. CONSTITUTION:The content of abrasive grains in a grinding wheel, i.e., concentration specified by JIS-B 4131, is set to 1-20. The tip sections of the abrasive grains exposed on the surface of the grinding wheel are flattened. The flattened portion of the abrasive grains is preferably set to about 30% or more of the cumulative area. When the flattened portion is less than about 30% of the cumulative area, the roughness of the grinding surface of a work becomes too rough, the abrasive grains are abraded, and the frequency of dressing is nonpreferably increased.

摘要： PURPOSE:To provide a surface of a glass plate where there is little undulation and damages and micro-cracks are shallow and few by laminating a hard sheet for grinding made of the organic resin containing diamond powder of the specified mean grain size as the surface layer for the grinding and a soft sheet with the cushioning quality as the layer of the rear surface. CONSTITUTION:A hard sheet 3 for grinding made of the organic resin containing diamond powder is laminated on a soft sheet 1 with an adhesive layer 2 to make the desired sheet for grinding. The diamond powder of fine grain size where the mean grain size is 3mum or under is used. If the diamond powder whose mean grain size is >=4mum is used. micro-cracks of >=1mum in depth are likely to be generated in the surface of the glass plate, and to remove this, further grinding of several mum becomes unpreferably necessary. The grain size of 0.1-2mum is more preferable to increase the working and removing speed and to make it difficult to increase the depth of micro-cracks.

摘要： PURPOSE:To improve corrosion resistance and wear resistance of the medium by providing a protective film comprising at least one layer on the upper side of a magnetic recording film and constituting the protective film to have an oxide layer as the most outer layer exposed to air. CONSTITUTION:The protective film is formed to prevent microcorrosion and to reduce inner stress by selecting the ratio of Zr/B, Zr/Si or Zr/(B+Si) in a proper range. Namely, by reducing the ratio of Zr/B, Zr/Si or Zr/(B+Si) and increasing the number of atoms of B, Si or (B+Si), inner stress can be reduced. By this method, the protective film can maintain enough corrosion resistance and good wear resistance even when the film is as thin as 100 - 500 Angstrom thickness.

摘要： PURPOSE:To prevent crosstalks and to allow the formation of tracks to a smaller pitch by providing recesses or projecting parts having the pitch, width and depth of specific ranges spirally or concentrically to the surface of a substrate. CONSTITUTION:The pitch of the recesses 2 or projecting parts on the substrate 1 is specified to 1-100mum, more preferably 1-20mum. The width of the recesses 2 or the projecting parts is specified to 0.2-50mum, more preferably 0.2-10mum. The depth thereof is specified to 0.01-10mum, more preferably 0.02-2.0mum. While a well shape, inverted trapezoidal shape, tray shape, etc., can be adopted for the inclination from the recesses 2 toward the projecting parts, the magnetic crosstalks from the adjacent tracks are prevented by making use of the fact that the magnetic field intensity in the recesses 2 is different from the magnetic intensity in the projecting parts. The track pitch is reduced to a min. 1mum in this way without being affected by the crosstalks.
