  • Patent number: 7295507
    Abstract: A signal can be detected based on a level slice system and detection delay time can be reduced by setting the recording density of a header field in a linear direction lower (coarse) than that of a user data recording field. Further, a signal can be detected based on the level slice system and detection delay time can be reduced by using a mark position form having a large detection margin as an information recording system of the header field. A readout error of a sector number due to a detection error is compensated for by recording address marks AM for attaining byte synchronization of the header field in both of a head portion and tail portion of information recorded in the header field.

  • Patent number: 7287618
    Abstract: A collision object protection assembly inflates and expands an air bag on a vehicle if a collision with the vehicle is detected or predicted. The collision object protection assembly includes a retainer positioned in a space between a bonnet hood and a front window glass of the vehicle and accommodating the air bag, and a cowl top arranged around the retainer to close the space between the bonnet hood and the front window glass. The retainer has an upper opening to be covered by a lid member. The lid member is a separate member from the cowl top.

  • Patent number: 7257172
    Abstract: A partial response (PR) waveform generator generates a digital value sequence of an expected PR waveform based on the output of a soft-decision Viterbi detector included in, for example, a first-stage decoder unit incorporated in an iterative decoder. The generator also generates flag information indicative of whether reliability of the digital value sequence is low or high, in parallel with the generation of the digital value sequence. An error detector detects error values in a PR equalized sample value sequence, needed for feedback control of a control target, using the digital value sequence of the expected PR waveform as a digital value sequence of a reference waveform. An error output controller controls the output of the error values detected by the error detector in accordance with the state of the flag information generated by the generator.

  • Publication number: 20070114090
    Abstract: A collision object protection device inflates and expands an air bag on a vehicle as soon as a collision of a collision object with the vehicle is detected or predicted. The collision object protection device includes: the air bag having a main body portion that expands along a lower part of a front windshield glass of the vehicle, a pair of pillar portions that expand along front pillars of the vehicle, and a pair of pillar base portions that connect the main body portion and the pair of pillar portions; and at least one inflator for supplying a gas to the main body portion of the air bag. A partition wall having one or more openings is arranged inside the air bag respectively at a boundary between the main body portion and the pillar base portion.

  • Patent number: 7211752
    Abstract: When a small-size dummy has collided against a vehicle and once the head of the small-size dummy hits the deployed external airbag at a pre-determined velocity, the inner pressure of the deployed external airbag is set to a characteristic such that the inner pressure takes a predetermined maximum level value capable of not only preventing the dummy from bouncing off the airbag but also preventing the head of the dummy from hitting the bottom of the airbag. When a medium-size dummy has collided against the vehicle, the inner pressure of the deployed external airbag is set to a characteristic such that the inner pressure decreases away from the maximum level value at a predetermined decrease rate to prevent the medium-size dummy from bouncing off the airbag.
