  • Publication number: 20190106104
    Abstract: A drive assist apparatus includes an electronic control unit configured to: compute, when an object that causes a blind spot is ahead of a host vehicle, a first reference velocity which is a velocity at which the host vehicle is able to run without colliding with a moving object assumed to be in the blind spot of the object; estimate a degree of risk associated with a road on which the host vehicle is running, based on environment information that indicates a running environment of the host vehicle; and compute a second reference velocity which is determined by correcting the first reference velocity based on the estimated degree of risk.

  • Patent number: 8537488
    Abstract: Embodiments of the present invention help to reduce damage of a head element portion or a magnetic disk in a procedure for specifying a heater power value for adjusting a clearance between the head element portion and the magnetic disk. In an embodiment of the present invention, an HDC/MPU sequentially performs data writing and reading while increasing heater power. The HDC/MPU further determines whether or not a head slider has retrieved the data properly. When the data cannot be retrieved properly, the HDC/MPU specifies a heater power value in a normal operation based on the heater power value at which the data could not be retrieved properly.

  • Patent number: 7719785
    Abstract: Embodiments of the present invention help to accomplish accurate and reliable clearance control. In one embodiment of the present invention, a disk drive device adjusts the clearance between a head element portion and a disk with a heater on a slider. The clearance control according to the present embodiment incorporates the variation in heater power efficiency in the clearance variation depending on the radial position. The clearance variation in a unit of heater power varies depending on the radial position. Taking account of the variation in the heater power efficiency in the thermal fly-height control (TFC) depending on the radial position in addition to the clearance variation between the head element portion and the disk caused by variation in fly-height or attitude, accomplishes more accurate TFC.
