  • Patent number: 8778183
    Abstract: A filtering apparatus that sucks liquid in hollow portions (10) of the filtering elements (1) via suction pipes (3) so that liquid passes the filtering elements and is filtered. Each suction pipe has suction holes (4) connected to the hollow portions. The suction pipes are inserted into through holes (2) of the filtering elements. The filtering elements are arranged side by side and connected to the suction pipes. A ring-shaped packing is interposed between the filtering elements, and water-tightly seals the clearance between the filtering element and the suction pipe. The through holes are arranged at peripheral locations of each filtering element. The suction pipes are inserted into the through holes of each filtering element. The filtering elements are held at the peripheral locations by the suction pipes.

  • Patent number: 8744248
    Abstract: When the playback speed of a moving picture is changed to a slower playback speed during playback of the moving picture, the playback at the slower playback speed starts from the top of the range which includes, out of the moving picture being played back, the frames being played back when an instruction to change the playback speed was received and in which frames having the same recording frame rate as the frames are continuously recorded. Consequently, when the playback speed is changed during the playback of a moving picture, the scene for which the user wishes to change the playback speed can be played back reliably.

  • Patent number: 8654642
    Abstract: A wireless packet transmission apparatus of this invention includes a packet priority controller that controls the order of transmitting packets with different priorities, and an adaptive modulation controller that changes the modulation scheme of the packets. The packet priority controller includes: a schedule selector that, when a modulation scheme is changed, with respect to packets with a priority of a predetermined value or more, provisionally sets a strict priority control scheme; and a comparison section that compares the transmission rate of the packets for which the strict priority control scheme is provisionally set and the transmission rate of the wireless packet transmission apparatus that is determined by the modulation scheme that has been changed by the adaptive modulation controller. Based on the comparison result, the schedule selector determines whether or not to set the strict priority control scheme for the packets for which the strict priority control scheme is provisionally set.

  • Publication number: 20130284655
    Abstract: A plurality of hollow filter sheets have a suction pipe inserted therethrough to be stacked with a ring-shaped packing clamped therebetween. Therefore, a gap between the hollow filter sheet and the suction pipe is watertightly sealed. In the hollow filter sheet, a hollow portion is provided between two filters, and then a spacer with a surface having pits and projections is provided in the hollow portion. A narrow passage space allowing liquid to pass through is provided between the filter and the spacer by pressing the two filters against surfaces of the spacer with the packings and causing the filters to be deformed into a shape according to the surfaces of the spacer. The narrow passage space is smaller than a drainage space between the filters and the spacer that are not clamped by the packings.

  • Patent number: 8437616
    Abstract: A recording system includes an input unit for inputting moving image data, a memory for accumulating the moving image data input by the input unit, a recording unit for recording the moving image data in a recording medium, and a selection unit for selecting either one of a first recording mode and a second recording mode. In the first recording mode, a predetermined amount of the moving image data is accumulated in the memory, is read out from the memory, and is recorded in the recording medium. In the second recording mode, the moving image data is recorded in the recording medium without being accumulated in the memory.
