  • Patent number: 7641966
    Abstract: A curable re-release adhesive which, when subjected to a curing reaction caused by irradiation with radiation, shows a sufficient drop of adhesion and causes the adherend to be warped to a minimized extent as developed by the shrinkage force caused by the curing reaction. The re-release adhesive contains a radiation-reactive polymer including a main chain and a plurality of intramolecular side chains, each such side chain having a terminal carbon-carbon double bond, a chain length of 6 or more in terms of number of atoms, and the same or a different number of atoms as each other side chain in the polymer. The release adhesive shows a shrinkage force of 30 MPa or less as developed by a curing reaction upon irradiation. A re-release adhesive sheet is also disclosed, including a substrate film and an adhesive layer containing the re-release adhesive, provided on one surface thereof.

  • Publication number: 20080095517
    Abstract: A combination apparatus incorporating a hard disk drive and an optical disc drive (audio-visual recording and reproducing apparatus) stores one or more keywords inputted as a result of user operation in a memory and monitors whether or not a closed caption signal contains any of the keywords. When the closed caption signal contains at least one of the keywords, output of images and audio corresponding to this closed caption signal and subsequent images and audio is stopped. A blue background may be outputted during stopping of outputting. The stopping of outputting may be released after a predetermined period elapses. When at least one of the keywords is contained in a closed caption signal during recording, images corresponding to the closed caption signal are subjected to mosaic processing and are recorded.

  • Publication number: 20080049103
    Abstract: When the camera surveillance mode is set, the signal waveform data of the input video image from the camera is compared with the signal waveform data of the reference video image stored in advance in the memory. Then, it is determined whether or not there is a change in the signal of the input video image from the camera. When it is determined that there is a change in the signal of the input video image from the camera, then it is determined whether or not a number of scan lines in the signal of the input video image exceeds the set scan line change quantity that corresponds to a surveillance level selected by a user from among a plurality of surveillance levels. When it is determined that the number of scan lines in the signal of the input video image from the camera exceeds the set scan line change quantity, a warning is generated, thereby notifying an intruder.

  • Patent number: 6995799
    Abstract: An information communication apparatus for conducting information communication such as a telephone conversation, sending and reception of E-mails and the like and for capturing an image of a subject comprises an image capturing unit for capturing an image through the zoom optical system, and a body unit for displaying an image and accepting a user's input. A rotating mechanism is provided between the image capturing unit and the body unit. When a user conducts information communication or carries the information communication apparatus, the image capturing unit is positioned so that the optical axis of the zoom optical system is substantially parallel to a display screen of a display. This prevents impairment of the portability of the information communication apparatus. When the user captures an image, the image capturing unit is positioned so that the optical axis of the zoom optical system is substantially perpendicular to the display screen of the display.
