摘要： Finite element methods are unsuitable for a dispersed system. Particle methods suitable for a dispersed system are limited in their particle shapes of only spheres that require many particles to model a complicated shape especially in 3D. Proposed procedures for a particle method are roughly as follows. 1): Judging the existence of the contact between particles as that between mathematically-smooth closed surfaces representing particle shape and size. 2): Assuming an imaginary contact point and an imaginary contact plane the same as when both closed surfaces are reduced with the same scale to touch at one point. 3): Calculating imaginary contact area and imaginary contact stiffness using the above point and plane. Based on these procedures, particle shapes are not limited but smooth. Therefore, a more complicated shaped problem in a dispersed system can be analyzed with a smaller number of particles. Additionally, combined use with finite elements enlarges usability.

摘要： A magnetic head has a recording magnetic yoke on the side of an air bearing surface of which a recording magnetic gap film is interposed and a reproducing magnetic yoke on the side of an air bearing surface of which a reproducing magnetic gap film is interposed. The magnetic yoke can serve concurrently for recording/reproducing. A recording coil supplying a recording magnetic flux to a recording medium through a recording magnetic yoke is disposed along one main surface of a magnetic yoke. An MR element in which a signal magnetic flux is led from a recording medium through a reproducing magnetic yoke is disposed along the other main surface on opposite side from a recording coil of a magnetic yoke. Or, at least on extension of a film plane of a magnetic gap film, a ferromagnetic layer is disposed so as for a film plane to exist in almost perpendicular direction relative to the film plane. According to such a head structure, reproducing sensitivity decrease of the reproducing MR head due to noise or occurrence of recording fringe can be suppressed.

摘要： At least one magnetic pole out of a pair of magnetic poles is provided with a T-shaped magnetic pole having a magnetic pole chip at the position contacting with a magnetic gap and an auxiliary magnetic pole which is wider than thereof. The proximity of an air bearing surface of the T-shaped magnetic pole is composed of a laminated film containing a magnetic material layer with a high saturated magnetic flux density which composes the magnetic pole chip and a portion of the auxiliary magnetic pole and a magnetic material layer with a low saturated magnetic flux density which composes the remaining portion of the auxiliary magnetic pole. When the front portion of the magnetic pole with the track width of 1.8 .mu.m or less is composed of a laminated film containing a magnetic material layer having a high saturated magnetic flux density and a magnetic material layer having a low saturated magnetic flux density, the thickness of the magnetic material layer having the high saturated magnetic flux density is 0.5 .mu.m or more. According to the above described magnetic pole, the magnetic saturation near the tip portion of the magnetic pole is controlled, so that preferable magnetic field strength and magnetic field gradient can be attained when the track width is narrowed.

摘要： An improved semiconductor element-manufacturing method which saves a semiconductor wafer from the occurrence of cracks or damage during the manufacture of a semiconductor element and enables solder layers to be deposited without irregularities in the thickness. The method starts with the step of forming a first metal layer acting as an ohmic electrode on each side of the element regions of a semiconductor wafer in which a plurality of active elements are formed or on the whole surface of each side of the semiconductor wafer. Then a second metal layer which has an anticorrosive property and acts as a brazing material when the semiconductor element is mounted between a pair of electrodes is selectively deposited by electroplating on each of the element areas in the first metal layers.Finally, those portions of the semiconductor wafer which are interposed between the active elements are chemically etched off with the second metal layers used as masks to separate the semiconductor elements from each other, thereby producing a plurality of semiconductor elements, each of which has its surfaces coated with the first and second metal layers.

摘要： A base film of a hard magnetic film containing Co as a structural element has a crystal metal base film such as a Cr film formed on the main surface of a substrate and a reactive base film (mixing layer) formed between the substrate and the crystal metal base film and having a reactive amorphous layer containing a structural element of the substrate and a structural element of the crystal metal base film. A hard magnetic film containing Co as a structural element is formed on the crystal metal base film. With the crystal metal base film such as the Cr film formed on an amorphous layer, a hard magnetic film with a bi-crystal structure can be obtained with high reproducibility. With the hard magnetic film, magnetic characteristics such as coercive force Hc, residual magnetization Mr, saturated magnetization Ms, and square ratio S can be improved without need to use a thick base film. The hard magnetic film containing Co as a structural element is applied to a bias magnetic field applying film of a magnetoresistance effect device and a record layer of a magnetic record medium.
