  • Publication number: 20080257106
    Abstract: A process for producing a high-cleanliness steel which can produce, without relying upon a high-cost remelting process, steel products having cleanliness high enough to satisfy requirements for properties of mechanical parts used under severe environmental conditions. The production process comprises the steps of: transferring a molten steel produced in an arc melting furnace or a converter to a ladle furnace to refine the molten steel; subjecting the molten steel to circulation-type degassing; and casting the molten steel into an ingot, wherein, in transferring the molten steel to the ladle furnace, a deoxidizer including aluminum and silicon, is added to previously deoxidize the molten steel, that is, to perform tapping deoxidation before refining in the ladle refining furnace.

  • Publication number: 20070204881
    Abstract: An apparatus and a method are provided for accurately analyzing and evaluating a degree of contamination on a chamfered part without mixing impurities from parts other than the chamfered part into chemicals. At a position in which, on a front plane flat part of a semiconductor wafer, a boundary region bordering the chamfered part can come into contact with the chemicals, a radius direction position of the chemicals (a distance between a chemicals center and a wafer center) is determined, scanning is performed in a circumference direction, and the chemicals including impurities are collected. Then, at a position that can be brought into contact with the both chamfered part of the semiconductor wafer and the boundary region, a radius direction position of the chemicals is determined, scanning is performed in the circumference direction and the chemicals including impurities are collected.

  • Patent number: 7266691
    Abstract: After a reproduction program is installed on a PC, a key for CD ripping is furnished e.g., from an FD. With the key for CD ripping, the music contents in a CD can be copied to a PC, however, it is not possible to download music contents from an EMD server for copying on a PD. For storing the music contents distributed from the EMD server on the PD, the reproduction program first acquired a key for EMD different from the key for ripping over the network. By so doing, the contents data distributed over the network may be improved in safety.

  • Publication number: 20070174302
    Abstract: Even if contents data distributed over a network are once destroyed, the contents data are restored, as the copyright protection is maintained. A PC memorizes backup of distributed music contents on a hard disc, at the same time as it transmits the using log information of the music contents stored in the hard disc to an EMD server. If the music contents in the hard disc are destroyed, the PC acquires the using log information from the EMD server to reproduce the backup data memorized in the hard disc depending on the using log information.

  • Publication number: 20070063944
    Abstract: When displaying moving images by using liquid crystal panels and others, a problem exists in that tail streaks occur, and image degradation is resultantly caused. To solve this problem, an echo suppression circuit divides a video signal into a pair composed of two successive frames for comparison between these two frames in signal level for the purpose of suppressing an echo phenomenon occurring when a liquid crystal panel displays video signals including moving images. If these two frames are not the same in signal level, the signal is accordingly corrected so as to equalize the signal level of these frames. Based on the video signals and others corrected by the echo suppression circuit, a controller operates the liquid crystal panel with AC drive through a source driver and a gate driver. As such, the drive voltage used to operate the liquid crystal panel with AC drive is adjusted so as to be balanced between positive and negative.

  • Patent number: 7161574
    Abstract: A liquid crystal display element driving method or a liquid crystal display device uses a liquid crystal display element having a plurality of pixels constituting a screen; divides a frame period into a plurality of write periods and outputs gate signals to select the pixels sequentially during the write periods; forms each of source signals such that the source signal includes a picture signal and a non-picture signal respectively assigned for the write periods; writes each of the source signals corresponding to the selected pixels to each of the pixels with its polarity being alternated; and displays an image responsive to the source signals on the screen of the liquid crystal display element in such a manner that a transmittivity of liquid crystals of each of the pixels is controlled in accordance with the written source signal, wherein the non-picture signal having a polarity identical to that of the picture signal to be written subsequently is written to the pixels.

  • Publication number: 20060119566
    Abstract: Disclosed is a liquid crystal display capable of ensuring brightness necessary for achieving satisfactory display by increasing ratio of light-emitting time to one frame period. A liquid crystal display is adapted to have a period (non-video signal write period) required for writing non-video signals different from video signals onto all the pixels before a video signal write period. In the non-video signal write period, the non-video signals are written onto the respective pixels, thereby starting response of the liquid crystal before the start of the video signal write period. In the non-video signal write period, a backlight is turned off, and thereby image degradation is prevented even when the non-video signals are written onto the respective pixels.

  • Publication number: 20050251690
    Abstract: A content sharing system is disclosed that can efficiently execute copyright management and can promote the degree of freedom and convenience in sharing of content within a legal range of private utilization. A group management server places a plurality of content processing apparatuses in terms of a unit of an owner into a group registration and issues a notification of a group ID of the group. A content recording apparatus adds a recorder ID thereof to production content produced thereby. Further, a content reproduction apparatus controls reproduction of content based on a recorder ID read out from content and a reproduction permission ID list. If the different processing apparatuses have the same group ID, the recorder ID can be added to the reproduction permission ID list.

    Abstract: The present invention is intended to create a license for a new piece of digital content created by linking two or more pieces of digital content. A license creation apparatus has a link ID acquisition block, a link pattern storage block, and a license creation block. The link ID acquisition block acquires a link ID from a license of digital content. The link pattern storage block stores a link ID combination and license creation information for determining contents of the license to be created, in a related manner. The license creation block creates a license. The license creation block acquires two or more link IDs from a link ID acquisition block and acquires license creation information related to a combination of these two or more link IDs from a link pattern storage block. The license creation block creates a license on the basis of this license creation information.
