摘要： A finite element mesh generating method generates triangular meshes used in finite element method analysis. This finite element mesh generating method includes the steps of (a) inputting orthogonal meshes used in finite difference method and mesh joining conditions, (b) setting flags indicating candidates of lattice points which are to be deleted out of lattice points of the orthogonal meshes, based on the orthogonal meshes, (c) reducing a number of meshes by joining the lattice points having the set flag and lattice points adjacent thereto, based on the mesh joining conditions, and (d) successively generating triangular meshes by searching nodes formed by lattice points remaining on the meshes after joining the lattice points and generating oblique sides of rectangles which are formed by connecting the nodes.

摘要： A yarn supply system for a loom includes a yarn supply member changing apparatus for replacing a using yarn supply member with a new one when the weft yarn of the used yarn supply member has been used up or broken. The new yarn supply member is supplied to the yarn supply member changing apparatus at a mounting position from a self-propelled carriage. The new yarn supply member is carried to a yarn supply position by a carrying member movably mounted on the yarn supply member changing apparatus. A weft yarn wound on a bobbin forming part of the yarn supply member has a free tip end section which has been inserted into the central hole of the bobbin. The weft yarn tip end section of the yarn supply member at the yarn supply position of the yarn supply member changing position is drawn out of the bobbin and threaded into a weft winding arm forming part of a weft measuring and storing device under the influence of air stream. Thus, the weft yarn is supplied through the measuring and storing device to a weft inserting nozzle which projects the weft yarn into a warp yarn shed so as to accomplish a weft picking.

摘要： According to one embodiment, in a disk drive having a disk and a flash memory, the disk controller controls the timing of performing a block erase when the flash memory is accessed, so that this timing may differ from the timing of a seek operation that is performed when the disk is accessed. This prevents the current flowing in the disk drive from exceeding the maximum operating current.

摘要： In formation of an upper shield of a magnetic thin film head by electroplating, a current density of electroplating is regulated stepwise with time. Thus, in the upper shield formation, a film composition and magnetic characteristic with respect to the direction of film thickness can be controlled precisely, making it possible to provide a magnetic thin film head featuring significantly reduced noise-after-write and output fluctuation.

摘要： The invention provides a magnetic domain controlling structure wherein a lamination stack M1 adjacent to a magnetoresistive stack of a GMR, CPP-GMR or TMR magnetic head has at least two magnetic films 14 and 16 anti-ferromagnetically coupled through a non-magnetic film 15, or the lamination stack M2 disposed on the end portions of the free layer of the magnetoresistive stack of the GMR magnetic head has a magnetic layer anti-ferromagnetically coupled to the free layer 2 through the non-magnetic film 27. Ferromagnetic film deposition dead zone area problems and the consequent problem of film rippling in free layer portions that reduces element sensitivity are prevented, as is the problem of increased error from read drift in the magnetic field exchange coupling method, resulting in a highly stable, highly sensitive MR head with no loss of magnetic field intensity.
