    Abstract: A method of manufacturing a rotating electrical machine has steps of a preparation step that accommodates the cap in a jig space while bringing the jig and the pulley in contact in an up-and-down direction so that an operation space is sealed, and a main step that decompresses the operation space to pressure lower than atmospheric pressure, moves the cap to an upper side in the decompressed operation space, and press-fits the cap into the pulley. By this, an inclination and a misalignment in the axial direction of the cap by the action of the reaction force can be suppressed since the reaction force acting downwardly on the cap can be weakened compared with the case where the cap is press-fit under atmospheric pressure. Therefore, the press-fit-state of the cap can be stabilized.

A multiferroic element may be disposed proximate to each memory domain allowing the magnetization of the memory domain to be changed using a spin torque current, and ensuring the stability of the magnetization of the domain when it is not being written. The domain boundary between the memory domain and one of its adjacent fixed domains may thereby be moved. An antiferromagnetic element may be disposed proximate to each fixed domain to ensure the stability of the magnetization of these.

  • Patent number: 8327524
    Abstract: Disclosed herein is an inductive component whose soft magnetic core is produced by pouring a casting resin into a mold filled with a soft magnetic alloy powder and by subsequently hardening the casting resin with the alloy powder in order to form a solid soft magnetic core. This technique prevents the surface insulation of the alloy particles from becoming damaged, thereby largely preventing the formation of bulky eddy currents in the resulting soft magnetic cores. This enables a distinct reduction in the electric loss of the inductive component.

  • Patent number: 8302286
    Abstract: A stator winding is manufactured by a forming step, a winding step, and a expanding step. In the forming step, an S-shaped offset shape is formed on a conductor part corresponding to a coil end part. Thereby, in a coil end part, it is possible to provide an expected shape stably at the coil end part. The conductor is wound around a bobbin in the winding step. In the winding step, a twisted shape is given to the conductor parts to be the inclined part of the coil end and the conductor part to be accommodated in a slot. In the expanding step, a preform product removed from the bobbin is expanded into a shape of the stator winding.

  • Publication number: 20120233849
    Abstract: A damascene process is utilized to fabricate the segmented magnetic core elements of an integrated circuit inductor structure. The magnetic core is electroplated from a seed layer that is conformal with a permanent dielectric mold that results in sidewall plating defining an easy magnetic axis. The hard axis runs parallel to the longitudinal axis of the core and the inductor coils are orthogonal to the core's longitudinal axis. The magnetic field generated by the inductor coils is, therefore, parallel and self-aligned to the hard magnetic axis. The easy axis is enhanced by electroplating in an applied magnetic field parallel to the easy axis.

  • Patent number: 8215003
    Abstract: A method of fabricating a reactor composed of a coil, a core, and a container, capable of suppressing the core to break when a current flows in the coil to generate magnetic flux. In the method, the coil is formed by spirally winding a conductive wire. The coil is immersed in an insulating film in liquid with electrical insulation. The coil is placed in a furnace. Annealing for the coil and thermosetting for the insulating film are performed at a temperature within 250 to 320° C. for a period of time within 30 minutes to one hour before forming the core in the container. The coil is then disposed in the container. Inside and outside areas of the coil in the container is filled with a resin mixture composed of magnetic powder and resin. The resin mixture in the container is hardened to form the core.

    Abstract: A method for winding a lead wire on a multi-winding electronic component is provided. The method can prevent winding slack of the lead wire, a break of the lead wire, and/or a terminal disconnection failure. A lead wire is wound around a winding core by a certain number of turns to form at least one first layer. Next, the lead wire is folded back toward an electrode, is pulled toward the electrode at an end-of-winding side so as to be across the second layer. Then, the lead wire is caught at a bottom part of the collar to form a final terminal part for boding to the electrode.
