    摘要: There are obtainable reliable and proper tracking correction and CTC even when fluctuations occur in an irradiation position of a sub-beam in a track at the time of performing tracking correction and CTC using three beams. Five beams (a main beam, sub-beams inA and inB, and sub-beams outA and outB) are generated. Reflection beams of the five beams are received, and a differential push pull signal DPPin corresponding to the sub-beams “in” as ± first-order beams and a differential push pull signal DPPout corresponding to the sub-beams “out” as ± second-order beams are generated. By assigning weights to the differential push pull signals DPPin and DPPout and computing the sum of the weighted signals, a tracking error signal Ste having an amplitude value which can perform tracking correction is generated.

    摘要: The present invention makes it possible to accurately and adequately adjust the position where sub beams are shone when performing tracking correction or CTC using three beams.The invention adjusts the positions where the sub beams are shone onto the surface of an optical disc DK by changing the angle of a diffraction grating 211 that is mounted inside an optical pickup. When performing adjustment, the angle of the diffraction grating 211 is performed in three stages: (i) rough adjustment, (ii) initial fine adjustment and (iii) continuous fine adjustment.

    摘要: A machine tool includes a spindle head (4) movable in a predetermined direction, a spindle (9) attached to the spindle head (4) for undergoing machining of a workpiece, a column (3) supporting the spindle head (4), the column (3) being movable over a predetermined plane (X-Y plane) perpendicular to the predetermined direction so that the spindle head (4) is movable over a plurality of machining regions (22L, 22R), a plurality of palettes (23L, 23R) each detachably mounting the workpiece and movable into and away from its associated machining region, and a table (13) mounting the plurality of palettes (23L, 23R) thereon. In one aspect of the invention, an external operation box (101) is provided from which a selected program number is entered and is impressed on an input port of a CPU (100). The CPU (100) calls a machining program identified by the selected program number to thus perform machining of the palette loaded on the associated machining region. In another aspect of the invention, an end point to which the column is finally moved is checked if it is within an allowable movement range of the column and the movement of the column is prohibited if the end point is out of the allowable range.

    摘要: A virtual image display device includes: an image forming element which forms an image to be displayed; and an optical element which reflects a light emitted from the image forming element to display a virtual image. The optical element has a concave shape opposite to a traveling direction of the light emitted from the image forming element. The light emitted from the image forming element enters the optical element without being reflected by other optical element. The image forming element is arranged in a direction substantially orthogonal to a direction of viewing the virtual image through the optical element.

    摘要: The display device includes: an image forming element which forms an image to be displayed; and an optical element which reflects a light emitted by the image forming element to display a virtual image. A first angle of the image forming element with respect to a traveling direction of the light traveling from a center of the image forming element to a center of the optical element is set in accordance with a second angle of the optical element with respect to the traveling direction of the light such that distortion of the virtual image displayed by the optical element becomes small.
