  • Publication number: 20050075818
    Abstract: The precision of a micromagnetization analysis is improved. Parameters of the micromagnetization assigned to the center of a divided microelement and the vector potential assigned to a side or a node of the element are received in procedure 1. A magnetic field equation which supplies an external magnetic field for micromagnetization is generated in procedure 2. A solution of the magnetic field equation is obtained in display 3. A time integral of a LLG equation is obtained using the solution in procedure 4. It is determined in procedure 5 whether or not the micromagnetization obtained in procedure 4 satisfies a convergence condition. When it is not satisfied, a magnetic field equation is corrected and a time is stepwise increased in procedure 6, and the procedures in and after procedure 3 are repeated.

  • Publication number: 20040248336
    Abstract: A method of manufacturing a photovoltaic device includes: a step of fixing thin metal wires which are coated with electroconductive resin, to a principal surface of a photovoltaic member; a step of heating the photovoltaic member to which the thin metal wires are fixed; and a step of pressing an elastic film against the photovoltaic member and the thin metal wires while the pressure of gas on the side opposite the photovoltaic member across the elastic film is larger than the pressure of gas on the photovoltaic member side. The thin metal wires to serve as a collector electrode provided in a photovoltaic member are prevented from bending. This makes it possible to produce, with high yield, photovoltaic devices that have no fear of being reduced in output by bent thin metal wires.

  • Publication number: 20040238663
    Abstract: A first rigid body has a horizontal surface on which a composite is to be placed and a non-horizontal surface on which the composite is not to be placed, with the horizontal surface and the non-horizontal surface forming a continuous horizontal linear edge. The continuous horizontal linear edge has a first portion, which is an edge of the non-horizontal surface, and a second portion, which is an edge of the horizontal surface, and the composite has a first region provided with a first member and a second region provided without the first member. While the composite is placed so that the first portion corresponds to the first region or the first region and a part of the second region and that the second portion corresponds to the remaining second region, the composite is separated by moving down a second rigid body from above the substrate.
