  • Patent number: 9903324
    Abstract: An engine device, which employs various types of fuels, plural fuel pipes can compactly be disposed without being thermally affected by exhaust gas. In the engine device, a gas fuel pipe that supplies gas fuel to a gas injector, a fuel oil pipe that supplies liquid fuel to a main fuel injection valve are disposed to be divided on both sides of a row of head covers arranged in a line. In addition, in the engine device, an intake manifold that supplies air taken in by a main combustion chamber toward an intake valve extends in parallel to the row of head covers in a cylinder block, and the fuel gas pipe and the intake manifold are arranged on the same side of the row of head covers.

  • Patent number: 7295499
    Abstract: The present invention has an object to stably reproduce wobble signals of all disks of CD-R/RW, DVD-R/RW and DVD-RAM by one wobble signal reproducing circuit. In the wobble signal reproducing circuit, an AGC (AUTOMATIC GAIN CONTROL) circuit for equating a push-pull circuit output of a wide range and an RF amplitude of an optical detector output of two systems obtained by push-pull, and an AGC (AUTOMATIC GAIN CONTROL) circuit for making a wobble amplitude uniform are provided with a function to hold a gain or to change over a response time constant, and at the time of reproduction of the DVD-R/RW, a land pre-pit region is detected by the push-pull output to hold AGC (AUTOMATIC GAIN CONTROL) or change over a response time constant. Besides, in an address information recording region (PID region) at the time of reproduction of the DVD-RAM, the AGC (AUTOMATIC GAIN CONTROL) is held or the response time constant is changed over.

  • Patent number: 7216159
    Abstract: An access point comprises a data table in which a correspondence relationship between a terminal ID specific to each mobile terminal and a virtual ID specific to a virtual LAN group to which each mobile terminal belongs, identifies a terminal. ID registered in a packet received from the mobile terminal, inserts a virtual LAN tag in the received packet, extracts the virtual ID corresponding to the terminal ID from the data table to register in the virtual LAN tag, and transfers it to switching means. The switching means selects an output port of the received packet based on the virtual ID registered in the virtual LAN tag of the received packet, and deletes the virtual LAN tag from the received packet and sends it.

  • Patent number: 6904086
    Abstract: An adaptive equalizer processing an input having a fluctuating amplitude realizes a stable adaptive equalization operation without changing over a reference value for computing an equalization error. An input signal is held as a sample with a timing signal shifted from a reference clock of the input signal by a phase of ½ cycle. An equalization output is compute from sample data. The difference between only the first output value after a zero-crossing and an arbitrary reference value is computed, and the computed value is set as an equalization error. A coefficient of the adaptive equalization circuit is updated from the equalization error and the sample data. To stabilize for displacement of symmetry of the input, the reference value of the equalizer is changed corresponding to the change of a digitization threshold value of a digitization circuit which constitutes a rear stage of the adaptive equalizer.

    Abstract: In an adaptive equalizer circuit, to an input having a fluctuating amplitude, a stable adaptive equalization operation can be realized without changing over a reference value for computing an equalization error. An input signal is held as a sample with a timing signal shifted from a reference clock of the input signal by a phase of ½ cycle. An equalization output is computed from an obtained sample data. The difference between only the first output value after a zero-crossing and an arbitrary set reference value is computed and the computed value is set as an equalization error. A coefficient of the adaptive equalization circuit is updated from the equalization error and the sample data. Further, to the displacement of the symmetry of the input signal, the reference value of the adaptive equalizer circuit is changed corresponding to the change of a binarization threshold value of a binarization circuit which constitutes a rear stage of the adaptive equalizer circuit.
