  • Publication number: 20050265169
    Abstract: A recording condition and a dubbing condition of a desired program that is to be broadcast are designated by using a remote controller. These conditions are stored in the information storage unit. In accordance with the recording condition, a controller permits a tuner to receive a program for which unattended recording is designated, and to record the program on an HDD. When a DVD is set in a dubbing unit and the dubbing operation is instructed by using the remote controller, a recorded program for which a dubbing condition stored in the information storage unit is applied can be dubbed. Then, the information for this program is displayed on a monitor so as to confirm the program and the dubbing condition, and to examine or correct CM skip if the CM skip is included in the dubbing condition. Thereafter, the dubbing operation is performed.

  • Publication number: 20050213018
    Abstract: The present invention provides a liquid crystal display device and a liquid crystal cooling unit, which are reduced in noise and have high cooling capability, and in which air is not directly blown on a liquid crystal panel module or a polarizing plate. A cooling jacket having an internal flow channel is formed by being adhered to a periphery of a light-transmissive, highly heat-conducting sapphire plate larger than a light transmitting area to which a polarizing film is applied or attached, by means of a highly heat-conducting adhesive. A liquid crystal cooling unit is formed by clamping the liquid crystal panel module by inserting a light-transmissive, highly heat-conducting substance. Further, the liquid crystal panel module and the polarizing film are cooled by circulating a cooling medium in the internal flow channel of the cooling jacket.

  • Patent number: 6850694
    Abstract: The present invention relates to a video signal processing apparatus for outputting an inputted video signal after subjecting the video signal to time axis correction, particularly to a video signal processing apparatus preferable in the case of subjecting the video signal to image compression. In the case in which a nonstandard signal is inputted to an image compression circuit of an MPEG2 encoder or the like, a drawback of freezing image or generating block noise or the like is resolved. A time axis correcting circuit stores an input signal to a memory and reads the input signal at a timing delayed from V synchronization of the input signal by a predetermined time period. For that purpose, a read synchronizing signal generator is reset at respective input field. A reset position is set to a position preceding the read V synchronization position by 3H through 10H.

  • Publication number: 20040105967
    Abstract: In coloration of a shaped article composed of a curable resin, the addition operation can be reliably conducted and a reliable coloration effect can be obtained in both the single-color addition and in the multicolor addition. A liquid-phase, non-colored photo-curable resin is cured by irradiation with laser light and a lowermost layer 5n is formed. A liquid-phase, photo-curable resin is applied on the upper surface thereof and a colored layer 5n-1 comprising a cured non-colored region and a liquid-phase pool region is formed. A color ink is drop-wise added to the liquid-phase pool region. The pool region is irradiated with laser light and cured to the same hardness as that of the non-colored region. A block-like coating film having the prescribed thickness if formed from the surface coating film produced by the color ink covering the pool region. As a result, the formation of the next layer (colored layer 5n-2) on the upper surface of colored layer 5n-1 can be conducted without obstacles.
