摘要： A recording device has a cartridge that holds a first ink tank filled with ink, and a second ink tank that is filled with ink of the same color; an inkjet head that prints using a first nozzle row that ejects ink supplied from the first ink tank, and a second nozzle row that ejects ink supplied from the second ink tank; and recording control unit that prints on a recording medium by ejecting ink from the first nozzle row or the second nozzle row. The recording control unit determines which ink tank contains more ink, and ejects ink to print from the nozzle row connected to the ink tank containing the most ink.

摘要： A passive optical network system such that the power consumption can be reduced as much as possible according to the end-user traffic. An OLT uses the DBA function thereof and sequentially uses frequencies in ascending order of transmission rate in order to sequentially allocate bands to ONUs in ascending order of the requested bandwidth. At this time, a frequency to be allocated is selected so that the bandwidth allocated to each ONU is narrower than a maximum bandwidth through which transmission using the allocated wavelength is enabled. An OLT uses a grant area to specify the transmission timing of the secondary station and to inform the specified transmission timing to the secondary station. In addition, an area is set for storing information used to inform the secondary station of a new frequency to be used.

摘要： In a light reception element such as an APD (Avalanche Photo Diode) used for receiving a high-speed and weak optical signal, it is possible to prevent the phenomenon of distortion of a signal inputted after a large-level light is received. A PON (Passive Optical Network) system includes an OLT (Optical Line Terminal) which can impartially and effectively transmit light reception data to each ONU (Optical Network Unit). According to a light reception amplitude received by each ONU, an inter-frame gap of an appropriate length is assigned for each ONU. The OLT includes a unit for measuring and accumulating the reception light amplitude and data on the inter-frame gap of an appropriate length decided in advance according to the characteristic of the light reception device and generates a grant value for assuring an inter-frame gap of an appropriate length by using the both information.

摘要： In a passive optical network system in which communication signals from a master station to a plurality of subsidiary stations are multiplexed by time division and transmitted, after converting (modulating) data with a high transmission speed to a low transmission speed, a base speed, in the master station, a header including an identifier destined for each subsidiary station is attached to the data with a low transmission speed and the converted data, respectively, the data and the header being multiplexed by time division inside a frame and transmitted to the subsidiary stations at the base speed. In the subsidiary station having received the concerned frame, only the data destined for the station itself is read, on the basis of the identifier included in the header, and by means of demodulation, the converted data are reconverted to the original high speed data and supplied to a user terminal.
