A plurality of beads (2) extending in the vehicle longitudinal direction are formed parallel to each other lined up in the vehicle width direction on an inner panel (1). Accordingly, an upper flange (5), a vertical wall (4), a lower flange (3), and a vertical wall (4) are formed connected in this order at a cross-section in the vehicle width direction. The vertical wall (4) includes a lower vertical wall (4a) and an upper vertical wall (4b), and there is a bend line (4c) at the boundary between the two which is bent. The inclination angle of the upper vertical wall (4b) is between 30° and 60° inclusive, which is greater than the inclination angle of the lower vertical wall (4a). The bend line (4c) is positioned more than ½ way up between the lower flange (3) and the upper flange (5) so as to be closer to the upper flange (5) than the lower flange (3).

According to an inner panel for vehicles of the present invention, a bead forming surface is so provided as to extend continuously with an upper edge part of a wall rising from a bottom surface of the inner panel. Upper beads and lower beads are formed on the bead forming surface. The upper and lower beads extend in a longitudinal direction of a vehicle and are arranged alternately in a width direction of the vehicle. The bead forming surface is positioned above a middle position between an upper surface of the upper bead and a lower surface of the lower bead. Further, the bead forming surface is positioned lower than the upper surface of the upper bead by 3 mm or more. With this structure, a sufficient first acceleration wave can be secured by expanding a stress propagation range in a direction perpendicular to the length of the beads with respect to the first acceleration wave and, also, by reducing a local deformation to be caused by a deformation load from the above of the vehicle during a head impact. Further, with respect to a load from below of the vehicle when contacting built-in components, the inner panel is easily crushed, which can lower a second acceleration wave.

A MEMS sensor driving device drives a MEMS sensor including a supporter provided on a surface of a substrate, an elastic member having one end connected to the supporter, and an oscillator which is supported by another end of the elastic member in a suspended state over the surface of the substrate and which is displaceable for the substrate. The MEMS sensor driving device includes a detecting unit for detecting an oscillation of the oscillator, and a feedback unit for amplifying a signal representing the oscillation detected by the detecting unit and inputting the amplified signal as a driving signal to the MEMS sensor.
摘要:
An inertial sensor includes an oscillator that is supported by an elastic supporting member such that the oscillator is floating relative to a base and the oscillator is displaceable along a single axis, and a displacement detection unit detecting a displacement of the oscillator. The oscillation of the oscillator is a simple harmonic motion along a Z axis. An X axis, a Y axis, and the Z axis, serving as reference axes of an oscillation coordinate system for the oscillator, are shifted to provide x, y, and z axes, serving as new reference axes. Position coordinates of the oscillator of the x, y, and z axes are determined in at least two points during one period of the oscillator. A difference vector (Δx, Δy, Δz) is calculated on the basis of the determined position coordinates. An angular velocity or an acceleration is obtained using the difference vector.

A flying head slider that keeps out dust particles while improving the CFH characteristics, skew dependence characteristics, and linear speed dependence characteristics for achieving a stable fly height. A flying head slider includes a positive pressure generating surface, which includes a leading pad for ensuring pitch stiffness; a pair of side pads, which are positioned behind of the leading pad and to the right and the left for ensuring roll stiffness; and a center pad, which is positioned between the side pads and controls the fly height characteristics. Furthermore, the flying head slider includes steps, which are at a lower height than the positive pressure generating surfaces and extend from the front of the slider toward side edges thereof in order to prevent dust particles from entering an area between the flying head slider and a disk surface.
