摘要： An aligning device includes a recognizing unit and a determining unit. The recognizing unit recognizes an intersection formed by two straight lines not parallel to each other among a plurality of straight lines of a register mark. The determining unit determines a position based on the recognized intersection. The register mark is used when an FPC terminal and a head terminal are superposed and connected. The FPC terminal is a wiring pattern formed on an FPC in a magnetic disk device. The head terminal is one of wiring patterns that are connected to a magnetic head in the magnetic disk device and is located in a portion that is superposed with the FPC terminal. The determining unit determines a position on the FPC where the head terminal is superposed.

摘要： According to the present invention, in a spark ignition-type internal combustion engine which has a spark plug and mounted in a vehicle, an ion current generated in a combustion chamber through the spark plug after ignition is detected and smoldering of the spark plug is determined on the basis of the detected ion current. An operation state of the internal combustion engine is detected and smoldering of the spark plug is determined based on that the detected ion current satisfies a predetermined condition when the detected operation state falls within an operation determination range set corresponding to an operation range in which an intake port pressure close to an atmospheric pressure is achieved using predetermined engine speed as an upper limit and a predetermined intake port pressure as a lower limit.

摘要： A fixing member is spaced from a head actuator by a predetermined distance. A flexible printed circuit board extends at least from the head actuator to the fixing member. The flexible printed circuit board is superposed on the surface of the fixing member. A viscoelastic layer and a protecting layer are overlaid on the surface of the flexible printed circuit board. A clip clips all the fixing member, the flexible printed circuit board, the viscoelastic layer and the protecting layer together. When a head slider is positioned, the head actuator changes its attitude relative to a recording disk. The inertial force based on the rotation causes the first flexible printed circuit board to vibrate when the actuator block stops rotating. The viscoelastic layer serves to absorb this residual vibration of the first flexible printed circuit board. Vibration of the flexible printed circuit board can be suppressed.

摘要： A magnetic disk device comprises a magnetic disk in which a data zone is formed. An actuator has a voice coil and a head slider carrying a magnetic head, the actuator being swung to move the magnetic head over the disk between an innermost position of the data zone and an outermost position of the data zone. A magnet has a magnetization center and is opposed to the voice coil so that a voice coil motor which swings the actuator is formed, the magnet having a north pole and a south pole confronting each other via the magnetization center. The magnetic disk device is provided so that a deviation of a center of the voice coil from the magnetization center when the magnetic head is in the innermost position of the data zone is substantially equal to a deviation of the center of the voice coil from the magnetization center when the magnetic head is in the outermost position of the data zone.
