    摘要: A turbocharger with a rotary electric machine has a permanent magnet, nonmagnetized metallic member, or surfaces of different light reflectivities fixed upon a rotatable member of the turbocharger, as a detectable means. The detectable means is disposed in a position corresponding to the angular position of magnetic poles of the permanent magnet rotor of the rotary electric machine. A detecting means is disposed in a position coacting with the detectable means for detecting the angular position of magnetic poles of the permanent magnet rotor. A shield means is provided for preventing the detectable means from being adversely affected by magnetic fields, oil, and dust, so that a detected signal of a high S/N raio can be produced for accurately detecting the angular position of the magnetic poles of the permanent magnet rotor as it rotates.

    摘要: An exhaust pipe injection control device to optimally control a degree of exhaust gas recirculation (“EGR”) opening during diesel particulate filter (“DPF”) regeneration. The device includes a regeneration-time opening control unit which controls a degree of EGR opening of an EGR device during DPF regeneration, and a regeneration-time opening map in which an optimal degree of EGR opening of the EGR device during DPF regeneration is set in advance according to an engine rotation speed and a fuel injection amount of an engine. The regeneration-time opening control unit performs exhaust gas recirculation by referring to the regeneration-time opening map based on the engine rotation speed and the fuel injection amount of the engine and controlling the degree of EGR opening of the EGR device.

    摘要: A plasmon generator positioned away from the substrate and extending to the air bearing surface (ABS) as facing a part of the waveguide. The plasmon generator has a propagation edge extending in a longitudinal direction. The propagation edge has an overlapping part overlapping the waveguide in the longitudinal direction, and a near field light generator positioned on the ABS and located in the vicinity of the edge part of the recording magnetic pole. The overlapping part of the propagation edge is coupled with the laser light propagating through the waveguide in a surface plasmon mode so that a surface plasmon is generated. The propagation edge propagates the surface plasmon generated in the overlapping part to the near field light generator. The magnetic recording element further has a grounding element electrically connecting the plasmon generator and the substrate.

    摘要: An MR element in a CPP-GMR structure includes a first ferromagnetic layer, a spacer layer that is epitaxially formed on the first ferromagnetic layer, a second ferromagnetic layer that is located on the spacer layer, and that is laminated with the first ferromagnetic layer to sandwich the spacer layer. A sense current flows along a lamination direction of the first and second ferromagnetic layers. Angle of magnetization directions of the first ferromagnetic layer and the second ferromagnetic layer relatively change due to an externally applied magnetic field.

    摘要: Provided is a method for manufacturing a thermally-assisted magnetic recording head including a light source unit with a light source and a slider with an optical system. The method comprises steps of: adhering by suction the light source unit with a back holding jig; moving the back holding jig, then aligning a light-emission center of the light source with a light-receiving end surface of the optical system in directions within a slider back surface of the slider; bringing the light source unit into contact with the slider back surface, with a suction surface of the back holding jig tilted from the normal to the slider back surface; applying a load to a load application surface of the unit substrate by a loading means to bring a joining surface of the light source unit into conformity with the slider back surface; and bonding the light source unit and the slider. This method can improve the conformity, thereby achieving adequately strong junction and adequately high accuracy in position.

    摘要: A plasmon generator has a near-field light generating part located in a medium facing surface. The plasmon generator has an outer surface including a plasmon exciting surface and a plasmon propagating surface that face toward opposite directions. The plasmon exciting surface is substantially in contact with an evanescent light generating surface of a waveguide's core. The plasmon propagating surface is in contact with a dielectric layer that has a refractive index lower than that of the core. The plasmon exciting surface includes a first width changing portion. The plasmon propagating surface includes a second width changing portion. Each of the first and second width changing portions has a width that decreases with decreasing distance to the medium facing surface, the width being in a direction parallel to the medium facing surface and the evanescent light generating surface.
