Abstract: A display apparatus makes it possible to check video contents of another video source while continuing to watch a presently watched program. A first region for displaying first video contents, and a second region for displaying selection icons to select second video contents different from the first video contents are formed on a display screen. The selection icons make possible selection from a plurality of video sources providing the video contents and including one or more broadcasting networks and a video recording medium. The broadcasting networks are one or all of ground-based broadcasting, BS broadcasting and CS broadcasting. The video recording medium is an HDD incorporated in the display apparatus and/or a removable HDD which can be inserted into and removed from the display apparatus.

Abstract: The present invention provides a broadcast receiving apparatus capable of allowing the user to check other available programs while viewing a certain program without switching the channel. This broadcast receiving apparatus is configured so that if such an off-screen program is selected, program information concerning the selected off-screen program is displayed in the [off-screen program check] OSD without occupying the currently viewed broadcast program and, asynchronously with this program information, broadcast video information concerning the selected off-screen program is rendered in an internal thumbnail window thereof.

Abstract: A fuel cell comprises a cathode (electrode catalyst layer), an anode (electrode catalyst layer), and a gas diffusion layer provided at least on one of the cathode and anode between a collector and the electrode catalyst layer and containing carbon having an oil absorption larger than that of a catalyst-supporting carbon used in the electrode catalyst layers. As a result, the dropping of the cell voltage due to external factor is suppressed, even if the cell temperature is low (room temperature to 50° C.). The water-absorption pressure of the water passage in the gas diffusion layer is higher than those of the electrode catalyst layers. The produced water and moving water in the cathode is absorbed into the water passage in the gas diffusion layer exhausted to the collector side. When a cell temperature is low, the evaporation speed of water from the collectors is lowered.

Abstract: A program information notifying method suitable for view or selection of video reservation is provided. In the method, a character string of program information is converted into a voice and the voice is output. When an item in specified program information is converted into a voice for reading aloud or when the program information exceeding a display zone is displayed, a letter at the end of the last character string of the program information is replaced with another letter indicative of ‘to be continued’ of the information to partially display the program information, and voice output is carried out by reading aloud all the program information. When a broadcast symbol is included in the program information, the broadcast symbol is removed, or converted into a character string meaning the broadcast symbol, and the character string is vocally output.

Abstract: An editing apparatus, an editing method and an editing program have remarkably improved operability. A first reproduction slider bar that indicates the current position of the reproduction of sound information and a reduced image are displayed on a display, the reduced image being obtained by reducing the image size of a bookmark image to a predetermined size, and are arranged at a sound position (time code position) related with the bookmark image. The reduced image is moved in response to an operation of moving it along the first reproduction slider bar.

Abstract: A sine wave electric signal whose frequency continuously varies within a predetermined frequency range is applied to a piezoelectric speaker, whereby a vibration frequency characteristic of the piezoelectric speaker is detected. A change of the frequency characteristic of the piezoelectric speaker when the piezoelectric speaker is brought into contact with concrete filled into a precast concrete form is detected based on the vibration frequency characteristic detected. With this unique feature, a filling status of concrete in the precast concrete form can exactly be detected independently of the hardness of water contained in the concrete and ambient temperature, and even if a temperature difference between air and the concrete is small.

Abstract: An electroconductive resin composition which exhibits excellent moldability and electric conductivity, and is produced at low costs. The electroconductive resin composition contains a zinc-based metal powder, low melting metal which melts upon molding, and thermoplastic resin. The zinc-based metal powder having a large surface area captures the molten low melting metal to prevent the phase separation thereof from both the resin and zinc-based metal powder. The zinc-based metal powder has a round configuration, as compared to that of fiber so as not to damage the fluidity of the resin greatly. Thus, the resultant electroconductive resin composition is excellent in moldability, and can be produced at low costs.

Abstract: The object of the present invention is to provide fuel cell including a cell that is formed by sandwiching solid polymer membrane between an anode and a cathode that generates electricity with stability and high performance by evenly moistening the solid polymer membrane. For this purpose, in a gas diffusion layer 24, which is positioned adjacent to a cathode catalyst layer 22, the content of fluororesin in an area on the side of the entrance for the oxidizer is set to be higher than in another area on the side of the exit so that the water repellency in the entrance side area is higher than in the exit side area. As a result, a water permeation suppressing part 24A, where the water permeability is relatively low, is formed in the area on the entrance side, while a water permeable part 24B, where the water permeability is relatively high, is formed in the area on the exit side.
