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.

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.

A cantilever type latch having the fixed end on the side of exposing the terminal end surface of the optical fiber is provided on the side of the plug housing. Near the center of the upper surface of the latch, an engaging projection which is to be engaged in the engaging hole formed in the adapter or the receptacle is formed. The engaging projection has the slope which decreases the height toward the fixed end side of the latch, in which the gradient of the slope is nearly equal to or greater than the rotation angle required for the elastic deformation of the latch with the fixed end functioned as the fulcrum. Thereby easy disconnecting of the latch is implemented.

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.

Disclosed herein are a semiconductor device and a method of manufacturing the same that increases the reliability of these devices as size design limitations decrease. Generally, a first insulating film, and wiring, including conductive film patterns and second insulating film patterns are formed on a substrate. Third insulating film patterns including a silicon-oxide-based material are formed on sidewalls of the wiring, and contact patterns and spacers on the sidewalls thereof for defining contact hole regions are formed on the wiring. The contact holes contact surfaces of the third insulating film patterns and pass through the first insulating film. Thus, the thickness of a second insulating film pattern used in the wiring can be minimized, thereby increasing a gap-fill margin between the wiring. A parasitic capacitance between the wiring can be reduced because silicon oxide spacers with a low dielectric constant are formed on sidewalls of the wiring.

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 defect inspection is performed for the optical film laminate and the adhesive layer.

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.
