  • Patent number: 10335686
    Abstract: A program that may cause an information processing apparatus that executes a game to execute: storing, in a storage unit, a first parameter associated with a first game content arranged in virtual space and a second parameter associated with a second game content arranged in the virtual space; starting a match between the first game content and the second game content; automatically changing a third parameter regarding a positional relationship between the first game content and the second game content in the virtual space to be closer to a first target value at a certain time change rate; changing the second parameter associated with the second game content, on the basis of the third parameter and the first parameter associated with the first game content; and determining that a user wins the match when the second parameter becomes a second target value.

  • Patent number: 8094412
    Abstract: Embodiments of the present invention relate disk drives, and in particular to realizing a positioning accuracy equal to that of an actuator having the mountable maximum number of suspensions, in an actuator having the smaller number of suspensions than the mountable maximum number. An embodiment of a magnetic disk device includes an actuator having an arm to which a suspension for applying a predetermined load onto a slider with a magnetic head is attached, and an arm to which a plate is attached instead of having the suspension. The plate attached to the arm in place of the suspension has a partially small section with respect to a section perpendicular to an arm longitudinal direction (constricted part), and the constricted part is located between a plate leading end and an arm attachment part.

  • Patent number: 8064171
    Abstract: Embodiments of the present invention help to reduce out-of-plane excitation force exerted on a coil in a voice coil motor of a magnetic disk drive, so that vibration of a magnetic head is suppressed. According to one embodiment, a voice coil motor has a flat magnet that faces a coil, and generates a magnetic field, and yokes that apply the magnetic field generated by the magnet to the coil. The magnet is provided with a magnetic flux guiding section, absorbing leakage flux from the magnet, on a most distal end of the magnet as viewed from a pivot axis. A most distal part of the coil as viewed from the pivot axis, may be situated in an outer side with respect to the most distal end of the magnet, and the magnetic flux guiding section is provided between the most distal end of the magnet and the most distal part of the coil.
