Publication number: 20140145422Abstract: The present invention provides an airbag that is capable of stabilizing a flow of a gas introduced into a lower air chamber to thereby stabilize an expansion behavior, the air bag being capable of stably constraining an occupant. Along a bulkhead configured to partition an airbag main body portion into an upper air chamber and the lower air chamber, a patch is mounted into the lower air chamber so that a rear end part is opposed to a distributing portion.

Patent number: 8339130Abstract: The surface length of a metal subject to be inspected is evaluated by detecting an eddy current without using a combination of a scale and visual or liquid penetrant inspection. An exciting coil and a detecting coil are scanned above the subject in a length direction. An eddy current detector measures an output voltage corresponding to scanning positions based on an output from the detecting coil. Based on an output voltage distribution curve indicating a distribution of output voltages corresponding to the scanning positions, position information is extracted corresponding to values which are within a differential voltage range and lower by 12 dB than a maximum value of the output voltages on the left and right sides of the distribution. A distance between the positions included in the extracted information is calculated to evaluate the length of a slit which is a defect present on the subject surface.Type: GrantFiled: February 16, 2011Date of Patent: December 25, 2012Assignee: Hitachi, Ltd.Inventors: Akira Nishimizu, Yoshio Nonaka, Isao Yoshida, Motoyuki Nakamura, Akihiro Taki, Masahiro Koike
