  • Publication number: 20090167005
    Abstract: An airbag deployment controller and a passenger protection device including the same are provided to prevent erroneous operation of an airbag due to noises and quickly deploy the airbag. The passenger protection device determines whether or not to drive an airbag unit, upon determining a detected value of a front acceleration sensor as being over a first collision threshold. Then, when determining to drive the airbag unit, the passenger protection device determines whether or not a detected value of a central acceleration sensor exceeds a second collision threshold. With the detected value being over the second threshold, it generates a driving signal and outputs it to the airbag unit in a final deployment control process. Thereby, the airbag unit operates an inflator to drive an airbag.

  • Publication number: 20070003013
    Abstract: Described herein is an X-ray beam conditioning device that has a crystal holder and a motor. The crystal holder supports a first crystal block and a second crystal block, each of which diffracts X-ray by a specific diffraction angle. The motor can rotate the crystal holder around an axis extending at right angles to a plane including an optical axis of X-ray and can support the crystal holder and fixedly supporting the crystal holder at thus rotated position. The crystal holder holds the first and second crystal blocks at such angles to each other that both crystal blocks diffract X-ray. The optical axes of the two crystal blocks can be adjusted, merely by rotating the crystal holder about said axis, namely only one axis.

  • Patent number: 6999557
    Abstract: Reciprocal-space mapping measurement of X-ray diffraction requires setting of the measuring range of 2?/? and setting of the measuring range of ?. When the measuring range of ? is designated in absolute angle, the absolute-angle-designated range is converted into a relative-angle-designated range to be acquired; preventing setting of a warped measuring region. When the measuring range of ? is designated in relative angle, it is acquired as it is. For the measuring range of 2?/?, any one of the absolute-angle-designated range and the relative-angle-designated range may be acquired.
