A perpendicular magnetic recording medium comprising a substrate, a soft underlayer, a seed layer, a non-magnetic FCC NiW alloy underlayer, a non-magnetic HCP underlayer, and a magnetic layer. We have discovered that the combination of a seed layer comprising Ta and a NiW alloy underlayer uniquely improves media recording performance and thermal stability by achieving excellent coercivity of the thin bottom magnetic recording layer and narrow C axis orientation distribution.

The present invention is directed to a method of and a mold for arranging features on a substrate to replicate the features with minimal dimensional variability. The method includes arranging features on a layer to minimize thickness variations in the layer that are attributable to density variations of the plurality of features on the layer. The features are transferred into an underlying substrate. It is believed that by forming the features so as to define a uniform fill factor in the layer, the thickness variations may be reduced, if not abrogated. To that end, one method in accordance with the present invention includes forming a flowable material on the substrate. Thereafter, a plurality of features is formed in a region of the flowable material. The plurality of features are arranged to provide a substantially uniform fill factor in the region.

An improved embolic filter frame having looped support struts. The frame configuration provides enhanced longitudinal compliance, improved sealing against a vessel wall, low profile delivery, and a short deployed length. The looped support struts have a high degree of "radial" stiffness with a low degree of "longitudinal" stiffness. In the deployed state, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains compliant in the longitudinal direction. Minor displacements of the support wire or catheter are therefore not translated to the filter. The looped support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter, the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced. When the delivery catheter constraint is removed during deployment, the struts "snap open" and assume a looped configuration which exert a high degree of force onto the vessel wall, creating an enhanced filter to vessel wall seal. In addition, the looped struts and the central collar connecting the support struts to the support wire, are positioned essentially within the plane of the filter opening. The overall deployed length of the embolic filter is therefore reduced.

An illumination device (L) includes a plurality of light source units (20) each having a light guide plate (1) and a plurality of light sources (21). The light guide plate (1) has an illumination region (4) through which incident beams of light from the light sources (21) are emitted outward and a light guide region (3) through which the incident beams of light from the light sources (21) are guided toward the illumination region (4), with the light guide region (3) and the illumination region (4) laid side-by-side. The illumination region (4) is divided into a plurality of light-emitting sections (9) by slit sections (8), provided in such a way as to extend along directions of optical axes of the light sources (21), which restrict transmission of light. At least one of the light sources (21) is provided to each of the light-emitting sections (9) in such a way as to be placed side-by-side along the light guide region (3). The light source units (20) are provided in such a way as to be placed side-by-side along at least along a first direction along which the light-emitting sections (9) are arranged in the illumination region (4). There is also provided a slit section (8) in at least part of a space between light-emitting sections (9) between light source units (20) adjacent to each other along the first direction. This makes it possible to provide an illumination device (L) capable of retaining its strength as a combination of light guide blocks while reducing leakage of light into an adjacent area and capable of emitting uniform light.

A compact near eye display generates image segments for a first dimension of an intended image. Each of the image segments is transformed into angularly distinguished beamlets that converge through a first dimension pupil within an eyebox. A scanning optic angularly separates the angularly distinguished beamlets of different image segments for creating a second dimension pupil. The angularly distinguished and separated beamlets propagate along a waveguide in a form that minimizes the thickness of the display in front of a viewer's eye and limits the overall size of the optics required to support the projection of virtual images into the viewer's eye.

A claw pole motor stator includes teeth for N phases (N being a natural number of 3 or more), for example, U-phase, V-phase, and W-phase teeth juxtaposed in an axial direction, return paths for interconnecting the U-phase, V-phase, and W-phase teeth, and (N−1) annular slots formed between the U-phase, V-phase, and W-phase teeth. A U-phase coil and one V-phase coil are housed in one annular slot, and another V-phase coil and a W-phase coil are housed in the other annular slot. In this way, only N sets of teeth and N−1 annular slots are provided for N phases, and thus it is possible to minimize the thickness in the axial direction of the stator compared with a conventional stator which requires 2N sets of teeth and N annular slots for N phases.

The light directed from a light source to a concave mirror and the light directed from a display device to an eyepiece optical system are intersected by each other in a layout. This allows the light source, the concave mirror, and the display device to be arranged in compactness adjacent to the eyepiece optical system without increasing the optical power of an illumination optical system. As the result, the apparatus can easily be minimized in the thickness or the overall size. A hologram optical element is provided where the relationship between the wavelength range Δλ1 at half of the diffraction efficiency of each of the three primary colors of the light in the hologram optical element and the wavelength range Δλ2 at half of the intensity of each of the three primary colors of the light emitted from the light source is defined by Δλ1<Δλ2. Accordingly, a component at desired wavelengths of each of the R, G, and B colors of the light emitted from the light source can be diffracted by the action of the hologram optical element and then directed to the pupil of the viewer. This allows the image to be increased in the color reproduction area and improved in the quality regardless of the display device actuated in a time-division mode.
