  • Patent number: 11981282
    Abstract: When an occupant has moved from a normal seating position, a case can occur where a hood-type airbag cannot be expanded and deployed since the airbag is stopped in the process of expansion and deployment due to contact with the head of the occupant. An airbag device is provided having an airbag, and an inflator for supplying gas to the airbag. In an expanded and deployed state where expansion and deployment of the airbag has been finished, the airbag includes a head protection chamber for blanketing an occupant from a vertex part of the head to a temporal part of the head, and a pair of lateral part protection chambers that are arranged on both of the left/right sides of the head protection chamber and that blanket lateral sides of the occupant.

  • Patent number: 5475666
    Abstract: A recording device for recording information upon optically modulated overwritable magneto-optical recording medium including four magnetic layers first records DC "1" and then a test signal at high and low recording laser power levels upon a test track of the recording medium. The high and low recording laser power levels are successively modified to scan a two-dimensional region of the high and low recording laser power levels, and the optimal high and low recording laser power levels are determined on the basis of the reproduction signal levels corresponding to respective combination of high and low recording laser power levers. The reproduction signal levels are represented upon the .alpha.-K plane which is divided into six characteristic regions, The optimal combination of high and low recording laser power levels is determined as a representative point within the region of correct reproduction with a predetermined allowance.

  • Patent number: 5070492
    Abstract: The present invention relates to apparatus and method for decoding a signal reproduced from an optical disc. The optical disc has a signal format for recording data from an original signal in a data area at the optical disc. The optical disc also has recorded thereon a clock signal having the same phase as the recorded data. During reproduction of the recorded signal from the optical disc, this clock signal is utilized to generate a delayed version of the reproduced data signal. This delayed signal is used to decode the reproduced data signal obtained from the optical disc, thereby enabling a phase shift of the reproduced clock signal to there produced data signal to be eliminated by circuit processing. During the recording on the data area of the optical disc, fixing data for setting phases of data reproducing recording clock and reproducing signal to optimum phases for decoding is recorded.
