摘要： The polarization-maintaining optical fiber 10 of the present invention is designed so that a plurality of core portions 12a,12b which have a high refractive index is provided in parallel along a single diameter direction in the cross section of the optical fiber, these core portions 12a,12b cooperating to propagate a single fundamental mode. In the production method for the polarization-maintaining optical fiber of the present invention, a plurality of holes 22 are formed longitudinally in parallel along a single diameter direction of a glass rod 21 having a low refractive index which forms the cladding, glass rods 23 for core use having a high refractive index which form the core portions are inserted into these holes 22, heating to form a unitary body is carried out, creating a preform which is then drawn. Further, the rare-earth-doped polarization-maintaining optical fiber of the present invention uses a rare earth element to dope the optical waveguide portion of the polarization-maintaining optical fiber, and can be employed in a light amplifier or laser oscillator. Moreover, the polarization-maintaining optical fiber coupler of the present invention is formed by bringing two or more polarization maintaining optical fibers into contact, heating, fusing and elongating them, and heating the vicinity of the connection point before and after connection.

摘要： A grating surface of a diffraction grating diffracts a laser beam emitted from a semiconductor laser device in ±1st order directions. The grating surface is formed in a rectangular or elliptic shape in such dimensions that a light spot formed on an objective lens by ±1st order diffracted beams is located in an aperture of the objective lens and not displaced from the aperture even if the objective lens is horizontally moved in a tracking operation. A grating surface of another diffraction grating has a width smaller than the width of an overlap region of a light spot on the diffraction grating corresponding to a part of a beam, diffracted in the +1st direction, entering an objective lens and a light spot on the diffraction grating corresponding to a part of a beam, diffracted in the −1st direction, entering the objective lens.

摘要： For page data containing shadow-casting objects, trap graphics are generated according to the following procedure. First, an ID drawing process is performed for all objects within a page, and based on the process result, a related graphic list indicating relative positional relationships between the objects is generated. Thereafter, an ID drawing process is performed for all objects in the area of each shadow-casting object, excluding the shadow-casting object. The result of the ID drawing process in the shadow-casting object area is reflected in the related graphic list, and thereafter, trap graphics are generated based on settings information in the related graphic list.

摘要： In trapping process of a multicolor image, an adjacent vector between an objective figure and a relative figure at an upper side is specified first. Then, with the use of the contour of the objective figure except for this adjacent vector, an adjacent vector between the objective figure and a lower relative figure is extracted. This enables to extract, as an adjacent vector, only the portion at which the color of the objective figure and the color of the lower related figure are adjacent each other in appearance. Therefore, the trapping process is executable without generating any unwanted color component on the image.

摘要： In trapping process of a multicolor image, it is judged whether trapping process is required or not, and trapping process is performed only when required. Specifically, trapping process is executed when in a portion where a plurality of figures constituting an image overlap, the plate color value of a relatively lower figure is erased or overwritten. This enables to execute trapping process only when there is the danger that a gap occurs in a boundary portion where different two colors are adjacent each other.

摘要： In the method of evaluating a characteristic of a magnetic head, a failure of a measuring equipment can be detected without stopping shipment of magnetic heads which have been previously evaluated, reevaluating the magnetic heads and stopping the measuring operations. The method of evaluating characteristics of the magnetic head comprises the steps of: storing measured data, which are a prescribed characteristic of the magnetic head measured by a measuring equipment, in storing means; detecting if the measuring equipment is failed or not on the basis of the measured data; and evaluating characteristics of the magnetic head when a failure of the measuring equipment is not detected in the detecting step.
