摘要： A vehicle-mounted information processing apparatus such as a car-navigation system detects that a key switch of the vehicle has been set up at a Lock position (i.e., the engine is stopped). After that, the apparatus performs data reproduction of data files in an order from the oldest, then re-recording the reproduced data files with no change added thereto. Here, the above-described data files, which are stored within a magnetic disk device built in the apparatus, have been not updated for a constant time-period. This re-recording prevents a data loss caused by a thermal decay in the case where the magnetic disk device is mounted inside the vehicle that is likely to have existed under a high-temperature environment for a long time-period.

摘要： In a magnetic head supporting apparatus having a second actuator for fine movement in addition to a first actuator having a voice coil motor for coarse movement, the second actuator is fixed so as to bridge the upper surface of a suspension and the upper surface of a suspension supporting member to support the suspension, and the second actuator is a plate-shaped structure which has two polarization regions separated by a non-polarized region and is formed by laminating piezoelectric flat plates in which the polarizing directions and the directions of electric fields to be applied are thickness directions. Thus, a magnetic disk apparatus which can be driven by a low voltage, a displacement in the vertical direction of the suspension is small, a productivity is high, and a recording density is high can be realized.

摘要： A voltage conversion apparatus includes a booster circuit, a boost stop circuit, a Zener diode, and a capacitor. The boost stop circuit includes a transistor. When an overvoltage equal to or larger than a breakdown voltage of the Zener diode is output to an output line of the booster circuit, the Zener diode is turned on. Accordingly, the transistor is turned on and a switching element is turned off to stop a boost operation. Further, the capacitor is charged through the Zener diode. Even when the Zener diode is turned off due to a drop in the output voltage after the stop of the boost operation, the transistor maintains its on state for a certain time by discharge of the capacitor. Thus, the stop of the boost operation is continued.

摘要： A conductive resin composition which includes an epoxy resin (A), a compound (B) having a (meth)acryloyl group and a glycidyl group, a phenolic resin curing agent (C), a radical polymerization initiator (D) and a conductive particle (E). The conductive resin composition which may be B-staged (semi-cured) at a relatively low temperature to exhibit sufficient tack-free properties and excellent pressure-sensitive tackiness. This permits temporary bonding of parts without involving solvent evaporation or light illumination, thereby reducing or avoiding an increase in facility costs. The conductive resin composition may thereafter be cured (C-staged) to provide a cured product having a desirable bond strength, while maintaining a low specific resistivity.
