At least one row of memory cells including memory cells having a threshold voltage lower than a desired erase threshold voltage is identified. The carbon fiber yarn can be a structure with metal particles on the surface, a dual-layered structure with a metal layer or a graphite layer on the surface, or a porous structure. The area including the indentation is at least greater than an area where comes in contact with the face of an occupant. An angular speed calculation unit calculates an angular speed of the rotor.
