Abstract: A head mounted display device has a mount which attaches the device to a user's head, a beam-splitter attached to the mount with movement devices, an image projector which projects images onto the beam-splitter, an eye-tracker which tracks a user's eye's gaze, and one or more processors. The device uses the eye tracker and movement devices, along with an optional head-tracker, to move the beam-splitter about the center of the eye's rotation, keeping the beam-splitter in the eye's direct line-of-sight. The user simultaneously views the image and the environment behind the image. A second beam-splitter, eye-tracker, and projector can be used on the user's other eye to create a stereoptic, virtual environment. The display can correspond to the resolving power of the human eye. The invention presets a high-resolution image wherever the user looks.

Abstract: An information recording carrier according to one embodiment has minute pattern including plural grooves or lands formed to be substantially in parallel and adjacent each other and comprises a supporting body having the minute pattern, a recording layer formed on the minute pattern formed on the supporting body and a light transmission layer formed on the recording layer. The minute pattern is formed under a relation of P<?/NA, where a pitch of each groove or land is P, a wavelength of a laser beam is ? and a numerical aperture of an objective lens is NA. The plural grooves or lands have at least a wobbling region and data is recorded wobblingly in the wobbling region by frequency shift modulation. A phase relation between a high frequency portion and a low frequency portion composing the frequency shift modulation is ±(?/20.5) to ±(?/0.751).

Abstract: A computer-based prosthodontic method is provided, for enabling a dental practitioner to define a finish line of a dental prosthesis of at least one tooth to be fitted over a tooth preparation. The method comprises the following steps: providing a three-dimensional (3D) digital data relating to the patient's dentition, the 3D data includes data representative of the surface topology of the preparation and its surroundings; generating first finish line data representative of at least a portion of the finish line and superimposing an image of the finish line on an image of the dentition; obtaining second finish line data determined on the basis of input received from a dental practitioner; and using the second finish line data to update the first finish line data and superimposing the updated data on the dentition image.

Abstract: Determining surface topology of a portion (26) of a three-dimensional structure is provided. An array of incident light beams (36) passing through a focusing optics (42) and a probing face is shone on said portion. The focusing optics defines one or more focal planes forward the probing face in a position which can be changed (72) by the focusing optics. The beams generate illuminated spots (t2) on the structure and the intensity of returning light rays propagating in an optical path opposite to that of the incident light rays is measured (60) at various positions of the focal plane(s). By determining spot-specific positions yielding a maximum intensity of the returned light beams, data is generated which is representative of said topology.

Abstract: A card manufacturing method for manufacturing the card and a card manufacturing apparatus for manufacturing the card are provided. The card 51 includes a card base 1, a first receptor layer 1a arranged on one side of the card base 1 to contain a sublimation-ink image 8, a protecting layer OC1 laminated on the first receptor layer 1a and an invisible-ink image 10 formed on the protecting layer OC1. Owing to the interposition of the protecting layer OC1 between the sublimation-ink image 8 and the invisible-ink image 10, the card 51 is capable of suppressing color fading of a sublimation ink in the image 8 in spite of a card structure where the sublimation ink and an invisible ink are printed so as to overlap each other, allowing the card 51 to be used for a long time.

Abstract: The compounds of formula I in which R1, R2, R3, R4, R5, R6 and n have the meanings as indicated in the description, are novel effective PDE3/4 inhibitors.

Abstract: On one surface of a piece of wooden sheet, a cloth or paper is adhered to make an adhered sheet. An approximately V-shaped notch is provided on the adhered sheet, the adhered sheet is wetted to be softened, and a lubricant which acts to keep water is impregnated thereinto. Edge portions of the notch are overlapped, and the adhered sheet is tentatively molded in an approximately horn shape by a first hot press molding. The adhered sheet is then dried, impregnated with thermosetting resin, and half-dried. The adhered sheet is subject to a second hot press molding. A moisture-proof agent is applied on the adhered sheet, a center hole for a voice coil and periphery are removed to make a speaker diaphragm having a predetermined dimension and shape.

Abstract: Needle-spring locking device for pump-injectors (injectors) of diesels, in which in order to significantly increase the lift and closing pressures of the nozzle needle, the locking spring (17) is disposed in the central cavity of the body around the outer surface of the plunger's bushing (2) and is connected with the needle (14) via a transversal cross-arm (15) disposed in the plunger bushing (2). This allows for increasing the average diameter of the needle spring (17) from 1.2-1.4 cm to 2-2.5 cm, and the spring power from 35-50 kgf to 180-220 kgf, respectively. In this case, the lift pressure of the nozzle body (10) (when the needle diameter is 0.6 cm) can amount to about 1200 kgf/cm2, and the closing pressure of the nozzle body (10) can amount to about 800 kgf/cm2, which corresponds to maximum injection pressures of 2000-2500 kgf/cm, as required for ensuring greater fuel efficiency and lower exhaust smoke and particle matter emission in future diesels.

Abstract: A surface light source device 1 includes a base member 3 provided with a plurality of point-source lines, each of which has a plurality of point sources 11 arranged in a line, and a plurality of diffuse transmission members 14 for covering the point-source lines. Each of the diffuse transmission members 14 is located while keeping substantially equal distances from the respective point sources 11 at least in a direction perpendicular to each of the point-source lines. Consequently, it is possible to allow light fluxes emitted from the point sources 11 to be transmitted in diffusion through the diffusion transmission members 14.

Abstract: A machine tool is described, in particular a grinding machine, with a tool storage device. The tool storage device contains an outer magazine wheel (34) and an inner magazine wheel (58), which are independently concentrically rotatable in a controlled manner. The outer magazine wheel (34) preferably holds grinding tools (56), while the inner magazine wheel (58) preferably holds grinding wheel protectors (68). The grinding tool (56) and the grinding wheel protector (68) are removed from the tool storage device and are returned to the latter by the tool spindle (30). The grinding tools (56) and grinding wheel protectors (68) can be exchanged independently in arbitrary combinations and possibly also simultaneously.
