  • Patent number: 8591750
    Abstract: Provided is a method for manufacturing a multilayer wiring board, whereby even if the multilayer wiring board suffers warping or irregularities, thin-film patterns with great uniformity that are to be used as a mask for forming a wiring layer can be obtained in a simple way. A primer-coated metal foil 20 composed of a primer resin layer 21 and a metal layer 22 is placed on a surface of a double-face CCL 10, which is prepared by applying metal layers 12 and 13 onto the surfaces of a support base 11, and the primer-coated metal foil 20 and the double-face CCL 10 are bonded and the primer resin layer 21 is cured. A via Vb is thereafter formed from the metal layer 22 side, and a metal-plate layer 30 is formed on the resulting metal layer 22. After that, the etched down metal-plate layer 30 and the metal layer 22 are patterned, and using the patterned layers as a mask, the primer resin layer 21 is patterned.

  • Publication number: 20100018630
    Abstract: In a method for manufacturing a composite wiring board, a through hole is formed in a sheet having a shrinkage-suppressing effect, and the through hole is filled with conductive paste to obtain a sheet for formation of a conductor. The sheet for formation of the conductor and a green sheet for a substrate in their laminated state are fired to obtain a ceramic substrate having a surface provided with a sintered metal conductor. A fired product of the sheet having the shrinkage-suppressing effect is removed from the surface of the ceramic substrate. Finally, a resin layer is formed on the surface of the ceramic substrate.

  • Patent number: 7561378
    Abstract: A data erasing device that erases data recorded on a magnetic disk, by a magnetic field generated in a horizontal direction by magnets, in order to prevent leakage of the data recorded on the magnetic disk of a magnetic disk device to be abandoned. The data erasing device includes a main body case having a path on which a tray is reciprocated, a demagnetizing circuit having plural permanent magnets adjacently disposed along the path in mutually adsorbing polarities, and a tray for accommodating the magnetic recording medium, and capable of reciprocating on the path. This tray includes a first accommodation groove and a second accommodation groove for accommodating the magnetic disk device. The first accommodation groove and the second accommodation groove cross each other to form an angle of 45 degrees or 90 degrees.

  • Patent number: 7416795
    Abstract: A method for manufacturing magnetic metal powder is provided. In the method, a powdered magnetic metal oxide is supplied to a heat treatment furnace with a carrier gas composed of a reducing gas. The heat treatment furnace is maintained at temperatures above a reducing action starting temperature for the powdered magnetic metal oxide and above a melting point of the magnetic metal in the powder. The powdered magnetic metal oxide is subject to a reducing process, and then magnetic metal particles, the resultant reduced product, is melted to form a melt. The melt is re-crystallized in a succeeding cooling step, to obtain single crystal magnetic metal power in substantially spherical form.

  • Patent number: 7233477
    Abstract: In a portable data erasing device, to prevent data leaks from magnetic disk devices to be disposed, data is erased by a simple operation. The data erasing device using a magnetic field generated by permanent magnets to erase data comprises a sliding tray, a main body and a swinging tray. The sliding tray is movable into and out from the main body, two permanent magnets, adjacently arranged so that the north and south poles thereof have mutually attracting polarities, are attached to the front end of the sliding tray. One end of the swinging tray is fixed to the upper surface of the main body by a shaft, so that a magnetic disk device can be mounted and swung on top of the main body. While the sliding tray is extracted stepwise from the main body, the magnetic disk device can be swung, and data on the magnetic disks erased.
