    摘要: A loudspeaker vibrating diaphragm with has a foam layer and two un-foamed skin layers formed on both sides of the foam layer. The average foaming magnification including the foam layer and two un-foamed skin layers is 1.1-3.0. The average foaming magnification is the ratio of the thickness of the resin after foaming (which equals the sum of the thicknesses of the foamed layer and the two un-foamed layers) to the thickness of the resin before foaming. The foam layer contains foaming bubble cells which are formed with their longer axes arranged in the thickness direction of the diaphragm. The thickness of each un-foamed skin layer is 0.05-0.20 mm.

    摘要: An overwritable method of magnetooptical recording uses an over write capable magnetooptical recording medium that comprises a substrate and a magnetic layer. The magnetic layer is stacked on the substrate and includes first and second layers each having a perpendicular magnetic anisotropy. When a high-level laser beam irradiates the medium, the magnetization of the second layer is reversed and a bit of one magnetization direction is recorded in the first layer under the influence of the magnetization of the second layer. When a low-level laser beam irradiates the medium, a bit of opposite magnetization direction is recorded in the first layer under the influence of the second layer. This overwritable method of magnetooptical recording exhibits a high C/N ratio without decreasing recording sensitivity.

    摘要: A magneto-optical recording medium includes a magnetizable amorphous alloy film having a perpendicular magnetic anisotropy to the film surface. The film is formed from rare earth metals and transition metal, such that the film has a Curie point that increases as the proportion of the transition metals increases. A magneto-optical recording method includes establishing a recording magnetic field and magneto-optically recording onto the film such that even if there are compositional changes in the film, little influence on recording sensitivity results.

    摘要: A magnetooptical recording method for recording data using a bit having upward-magnetization and a bit having downward-magnetization on a recording layer of a magnetooptical recording medium comprises the steps of using, as the medium, a multilayered magnetic recording medium consisting of a first layer having a perpendicular magnetic anisotropy acting as a recording layer, and a second layer having a perpendicular magnetic anisotropy acting as a reference layer; moving the medium; applying an initial field so that, before recording, the direction of magnetization of the recording layer is left unchanged, and that of the reference layer is aligned either upward or downward; radiating a laser beam onto the medium; pulse modulating an intensity of the laser beam in accordance with binary data to be recorded; when the laser beam is radiated, applying a bias field to the irradiated portion; and when the intensity of the pulse-modulated laser beam is at high level, forming one of the bit having upward-magnetization and that having downward-magnetization, and when the intensity of the pulse-modulated laser beam is at low level, forming the other bit.

The outer diameter of the upper dies is smaller than the inner diameter of the first recess so that a gap is formed between the inside wall of the first recess and the outside wall of the upper die. A workpiece is put between the lower and upper dies, and the upper die is pressed against the lower die to form the element.
