  • Patent number: 7783416
    Abstract: A navigation server capable of guiding a mobile subject such as an automobile by a navigation device, while appropriately evaluating the level of safeness of individual link in a disaster occurring area in consideration of the actual disaster condition is provided. According to the navigation server of the present invention, the links included in the disaster occurring area are extracted, and the cost of each of the extracted links is evaluated on the basis of the probe information.

  • Publication number: 20090277304
    Abstract: According to exemplary embodiments of the present invention, a process for production of an amorphous alloy can be provided at low cost by, e.g., efficiently removing magnetic-property-degrading Al and Ti when using inexpensive Fe—B or scrap as an amorphous alloy raw material. An exemplary embodiment of the process for production of an Fe-based amorphous alloy ribbon can comprise, by mass, e.g., 2 to 4% of B, 1 to 6% of Si, and a balance of Fe and unavoidable materials is provided. For example, it can be determined whether the molten alloy obtained by melting a main raw material has a Ti concentration or Al concentration of 0.005 mass % or greater: When such even occurs, iron oxide source having an iron content of 55 mass % or greater can be added thereto to reduce both Ti and Al to less than 0.005 mass % by oxidative removal. Alternatively, it is possible to determine whether the main raw material has a composition whose Ti concentration or Al concentration is 0.

  • Publication number: 20080151722
    Abstract: This invention provides an optical disc device and method for discriminating between DVD and HD-DVD more rapidly. After an optical pickup has been stopped above a data region on the optical disc, a tracking error signal generator acquires amplitude “Vdpp” based on a DPP method and amplitude “Vdpd” based on a DPD method as tracking error signals. A disc discriminator discriminates the kind of optical disc by comparing the acquired “Vdpp” and “Vdpd” data with a threshold level “Vth”. Alternatively, the optical pickup is stopped above the data region and a system lead-in region on the optical disc, and then amplitude values “Vdata” and “Vlead” of tracking error signals are acquired and compared.

  • Publication number: 20080117783
    Abstract: An optical disc apparatus according to the present invention steadily performs a focus jump operation and a track-crossing seek operation relative to an optical disc having a plurality of recording layers. A signal processing section generates a focus error signal based on a conventional astigmatism detection (CAD) system and a focus error signal based on a differential astigmatism detection (DAD) system from a detection signal generated by an optical detector. When a focus jump is to be performed from one recording layer of the optical disc to another recording layer, a focus drive signal that is generated from the focus error signal based on the CAD system is used. When a read/write operation is to be performed in relation to one recording layer, a focus drive signal that is generated from the focus error signal based on the DAD system is used.

  • Patent number: 7353102
    Abstract: An internal combustion engine includes parallel first and second intake passages, and the intake passages respectively include first and second superchargers. A first airflow meter measures the intake air amount in the first intake passage. A second airflow meter measures the intake air amount in the second intake passage. An ECU obtains an air amount difference between the intake air amount measured by the first airflow meter and the intake air amount measured by the second airflow meter to compare the obtained air amount difference with a predetermined abnormality determination value. The ECU determines that an abnormality has occurred in one of the superchargers when the air amount difference exceeds the abnormality determination value. The abnormality determination of the superchargers is based on the air amount difference between the intake passages. This accurately determines the occurrence of an abnormality in the superchargers regardless of structure of the intake passages.

  • Publication number: 20070171781
    Abstract: The present invention provides an optical disk apparatus capable of stably performing a layer jump on an optical disk having plural recording layers and non-uniform interlayer distances. In an optical disk with at least three recording layers and non-uniform interlayer distances between respective recording layers, if a layer jump is carried out from a first recording layer to a second recording layer, a distance from the first recording layer to the second recording layer is obtained and driving voltages set according to the distance are applied to an actuator for the layer jump to carry out the layer jump. At this time, interlayer distances for combinations of the respective recording layers and applied driving voltages thereto are stored in a memory in advance and when necessary, corresponding driving voltages are read out from the memory and are set for the layer jump.

  • Publication number: 20070172397
    Abstract: Collectors are provided on a pair of exhaust passages extending in parallel from an internal combustion engine respectively. Each of the collectors collects black smoke particles (unclean substance) included in exhaust gas. One of a pair of differential pressure detectors detects a first differential pressure between upstream and downstream of one of the collectors while the other differential pressure detector detects a second differential pressure between upstream and downstream of the other collector. Upon finishing a regeneration process of removing the black smoke particles in each of the collectors, a control computer estimates an exhaust gas flow rate of each of the exhaust passages based on the first differential pressure and the second differential pressure.
