    摘要： Single flat metal sheet blank in which thin metallic parts including side frames which are to form side walls, a shield plate and external lead and the like are connected together in a developed state in positional relationships necessary for the assembly of the high-density circuit module. A circuit board is then placed on one side of the shield plate of the flat metal sheet blank. Terminals having pedestals are formed on the shield plate. The terminals are inserted into holes formed in the circuit board and connected to conductors on the circuit board. Then, operations such as severance or bending are effected on selected connecting portions at which the thin metallic parts arranged in developed state are inter-connected, and required processings are executed on the portions to be jointed, whereby the circuit module is completed. According to this production method, a space for receiving circuit components is formed between the circuit board and the shield plate, so that both sides of the circuit board can be used for mounting the circuit components, whereby a high packaging density is attained.

    摘要： A perpendicular magnetic recording medium includes an intermediate film formed of a plurality of layers between a soft magnetic film and a perpendicular magnetization film. The intermediate film includes at least two layers, i.e., an oxygen-containing layer, or a nonmetallic element-containing layer containing nitrogen, silicon or carbon, and a metallic layer formed on a surface side of the oxygen-containing layer or the nonmetallic element-containing layer. The metallic layer includes a plurality of isolated island-shaped structures. Crystal grains of the perpendicular magnetization film are formed so as to correspond to the isolated island-shaped structures. As a result, a high recording density is obtained.

    摘要： In a gradation display method, an image is divided into pixels having fine areas, this pixel is furthermore divided into very fine pixels (Si) having very fine areas, and then gradation is displayed based upon a ratio of a colored very fine pixel (Si) with respect to all of very fine pixels (Si) within a pixel. Also, the above-described colored very fine pixel (Si) is formed by both a first growth core which is formed by increasing the number of colored very fine pixels of a single cluster, and a second growth core which is formed by increasing the number of colored very fine pixels of another single cluster.

    摘要： Disclosed is a magnetic recording medium and a method for manufacturing the same to provide a magnetic recording medium reducing medium noise and having excellent thermal stability. The magnetic recording medium includes a substantially amorphous seed layer and a polycrystal underlayer made of crystal grains having a substantially columnar structure, the polycrystal underlayer contacting thereto. In a boundary between the seed layer and the underlayer, fine grooves having a period up to as large as the magnetic layer crystal grain diameter are formed in the disc circumferential direction. Accordingly, the magnetic recording medium is allowed to have a grain shape with a value obtained by dividing the average grain diameter for the disc circumferential direction by the average grain diameter for the disc radial direction of no less than 0.5 and no more than 0.9, thus achieving simultaneously reduction of the medium noise and thermal stability.
