  • Patent number: 7762679
    Abstract: A ferrule includes a body having a cylindrical shape. Elastic gripping portions are arranged on the body so as to bulge radially inwardly. The elastic gripping portions can have elastic contact with the outer circumferential surface of a glass tube. The body of the ferrule is mounted to the glass tube via the elastic gripping portions capable of elastic and radial deformation. Thereby, the variations in outer diameter of the glass tube can be absorbed, and therefore the dimensional control with high precision is not required for glass tubes at the time of manufacturing. This leads to cost reduction.

  • Patent number: 7764585
    Abstract: There is provided an optical head which have no such problems regarding increase in cost and size thereof and can reduce errors by suppressing crosstalk components attributable to reflection on lands of a magneto-optical recording medium and thereby prevent degradation of reproduction characteristics. An optical element includes a light separating section for separating outgoing light and return light, and a phase compensation section for imparting phase compensation to light incident thereon. The optical element is provided on a light path of return light between an objective lens and a photodetector, so as to be closer to the photodetector than the light separating section is. This makes it possible to impart the phase compensation to the return light and prevent the degradation of reproduction characteristics. Light separating elements such as beam splitter are no more necessary in the configuration, with the result that decreases in size and cost can be realized.

  • Patent number: 7764261
    Abstract: A liquid crystal display device includes a panel having pixel electrodes arranged at intersections of a plurality of signal lines via switching elements for transmitting display data and a plurality of scanning lines for transmitting control signals, and a control circuit for controlling the panel. The liquid crystal panel is divided into first pixel regions and second pixel regions adjacent to the first pixel regions. The control circuit carries out impulse driving in which the control signals transmitted to each of the scanning lines are activated two times in one frame period for displaying an image. The control circuit writes the display data in either one of the pixel regions and writes reset data in the other pixel regions when the control signals are activated once of the two times. By writing the reset data in the pixel regions, the display data written in an immediately preceding frame are reset.

  • Patent number: 7764292
    Abstract: The present invention provides a three dimensional graphics processing apparatus for performing an anti-aliasing processing in an sufficient manner, without using the conventional area DDA, by using a line buffer as an area for storing display image data to reduce the required memory area, while the increase of the calculation time is restricted by performing calculation suitable for the polygon edge without degrading the precision of the calculation. In the three dimensional graphics processing apparatus, the coordinates of the intersection points between the polygon edge and the scanning lines are calculated from information on the starting vertex and the ending vertex of the polygon edge and information on the scanning lines. The calculation method is changed in accordance with the characteristics of the polygon edge. Further, a blending coefficient for the anti-aliasing process is obtained by calculating an area ratio of an internal region of the polygon occupied within a pixel.

  • Publication number: 20100182560
    Abstract: A method for repairing a glass substrate is a method for repairing a glass substrate (10) having a depression (60) formed in a display region (5). Into the depression (60), plural types of starting material from which a cross-linked epoxy resin or a cross-linked (meth)acrylic resin is made are put together with a photoinitiator, and the starting materials thus put are copolymerized by light irradiation and heat treatment. In the result, the depression (60) in a surface of the glass substrate (10) is repaired by a transparent resin (65) obtained through the copolymerization of the plural types of starting material. Therefore, the glass substrate (10) can be repaired at a low temperature without performing a sintering process.

  • Publication number: 20100182350
    Abstract: In general, when a user views an image displayed on a display apparatus, visual environments, such as ambient brightness, a distance from the user to the display apparatus and so on, may disadvantageously cause the image displayed on the display apparatus to become difficult to view. Moreover, it is complicated and troublesome for the user to enter information of ambient light amount and others when setting a picture quality. An image display apparatus holds both question constituent information related to visual environments and choice information serving as answers to questions constituted by the question constituent information, and further holds a plurality of picture quality control rules suitable for visual environments assumed in accordance with the choice information serving as the answers.

  • Publication number: 20100185710
    Abstract: The objective of the present invention is to manage reference movies using an index file, without causing the user to be perplexed. The reference movies are generated because of, for instance, the upper limit of the file size. The index file manages sets of information regarding the files being managed. Examples of these sets of information are information for determining whether or not a file is presented to the user, information for determining whether or not a file is original, and information indicating whether or not nondestructive editing has been done. Based on such information, the erasure, displaying a list, and so on are carried out. Thus, it is possible to manage the reference movies using the index file, without causing the user to be perplexed.

  • Publication number: 20100183223
    Abstract: When N kinds of foreground identifiers for identifying color information of a foreground of a color image is to be reduced to M smaller than N, foreground identifiers corresponding to similar chromatic colors are merged and foreground identifiers corresponding to similar achromatic colors are merged but a foreground identifier corresponding to a chromatic color and a foreground identifier corresponding to an achromatic color are not merged. Thus, image quality degradation derived from color change from an achromatic color to a chromatic color or vice versa may be suppressed. On the basis of a foreground layer including the M kinds of foreground identifiers, M binary images respectively corresponding to the M kinds of foreground identifiers are generated, each of the binary images is subjected to lossless compression and a background layer is subjected to lossy compression.
