  • Publication number: 20030068157
    Abstract: In a disc playback apparatus in which a plurality of digital versatile discs (DVDs) are loaded in a disc changer, a key-image extracting unit causes menu screens recorded on the plurality of loaded DVDs to be decoded, and generates predetermined key-image data by reducing video data of the menu screens decoded by a video decoder. The key-image extracting unit stores the generated key-image data in a hard disk device. An index-screen generating unit reads the key-image data stored in the hard disk device to generate and display a predetermined index screen including key images produced using the key-image data. The disc playback apparatus allows a user to readily grasp the content of the DVDs loaded therein.

  • Publication number: 20020177434
    Abstract: A receiver and a receiving system capable of obtaining content related information corresponding to a retrieval key are provided. When a retrieval instruction is performed by a user, a retrieval key setting section sets the artist name of a musical piece provided by a program being received as a retrieval key. A related information retrieval section obtains program content data added to distribution information of another program, and retrieves content related information (for example, information such as the scheduled date of the sale of a new musical piece) corresponding to the retrieval key set by the retrieval key setting section. When the content related information corresponding to the retrieval key is extracted, a display processing section creates image data for displaying the extracted content related information and displays the image data on a display section.

  • Publication number: 20020093291
    Abstract: A discharge is initiated in a cell in which an address discharge is conducted at a first timing T1 in a charge adjustment period. Next, at a second timing T2, a discharge is initiated for adjusting a wall charge in a cell where a charge remains therein because the address discharge does not occurred. Thus, some negative charges are formed in an X electrode and a Y electrode, thus preventing a false discharge from occurring in an unselected cell.

  • Patent number: 6033481
    Abstract: A plasma processing apparatus in which power consumption is reduced, which can generate uniform plasma in a large range and in which minute processing in high etching selectivity and in high aspect ratio is enabled is disclosed. High density plasma is generated in a vacuum vessel housing a processed sample utilizing an electron cyclotron resonance phenomenon caused by an electromagnetic wave in an ultra-high frequency band and a magnetic field and the surface of the processed sample is etched using this plasma. An electromagnetic wave in an ultra-high frequency band for generating plasma is radiated from a planar conductive plate consisting of graphite or silicon which is arranged opposite to the surface of the processed sample into space inside the vacuum vessel. High density plasma in the low degree of dissociation can be generated by using an electromagnetic wave in an ultra-high frequency band and as a result, the controllability of etching reaction can be enhanced.
