    Abstract: PROBLEM TO BE SOLVED: To provide the effective and highly practical protection mechanism of a magnetic disk device, capable of finely dealing with the used situation of a portable terminal device.
    SOLUTION: This protection mechanism is provided with a registered stable position data storing part 53 for storing the information of a stable state indicating the setting of a magnetic disk device in a stable using environment, a stationary state measuring part 51 for determining whether the magnetic disk device is in a stationary state or not based on the information of acceleration applied to the magnetic disk device and detected by a sensor 20, and an operation state determination part 54 for determining whether the stationary state is the stable state stored in the registered stable position data storing part 53 or not when the magnetic disk device is determined to be in the stationary state, and setting a prediction detecting sensitivity for predicting the occurrence of shocks on the magnetic disk device based on the result of the determination. A magnetic head operation control part 60 retreats a magnetic head 11 when the prediction of shock occurrence is detected based on the detecting sensitivity.

    Abstract: PROBLEM TO BE SOLVED: To provide an information processing device that prevents the transition of a system operating state by a user's erroneous input. SOLUTION: The information processing device which transits a system operating state according to a user's direction input comprises a request signal acquisition part for acquiring a transition request signal requesting the transition of a system operating state, an instruction signal generation part for generating a transition instruction signal for transiting the system operating state according to the transition request signal acquired by the request signal acquisition part, an operation control part for transiting the system operating state according to the transition instruction signal generated by the instruction signal generation part, and an instruction signal generation control part for prohibiting the instruction signal generation part from generating a transition instruction signal if the request signal acquisition part reacquires the same transition request signal as the transition request signal until a time for transition processing in the normal transition processing of the system operating state by the operation control part elapses.

    Abstract: PROBLEM TO BE SOLVED: To provide an information processor which prevents the protection function of a disk drive for the anticipated impacts from causing troubles in the predetermined processing, and also to provide a control method of the information processor, and a program and a recording medium thereof.
    SOLUTION: When the predetermined conditions are fulfilled after the magnetic disk drive 13 is made highly shockproof, a second prediction means 20 issues a second prediction that the anticipated impact is not imminent. When power switching is made impossible by the protection function of the magnetic disk drive 13, a condition relaxation means 28 relaxes the conditions for issuing the second prediction in the second prediction means, and prompts the disk drive 13 to return to the state allowing to read/write the data. The information processor 10 has a protection function to switch the drive 13 to the highly shockproof state unable to read/write the data when an impact to the magnetic disk drive 13 is anticipated, and a power switching function to properly switch the drive 13 to the power saving mode. In the power switching function, disk accessing is requested, and the power switching is often suspended for a long time if an impact is predicted to be imminent to the disk drive 13. Such cases are prevented.

    Abstract: PROBLEM TO BE SOLVED: To prevent a situation in which an authenticator is read out by a malicious code and unauthorized authentication is gained by using the authenticator read out. SOLUTION: An authenticator acceptance period detection means 96 detects a period over which any yet-to-be authenticated program is guaranteed as inoperative as an authentication acceptance period. A program execution means 97 defines a period for sending the authenticator to be within the authentication acceptance period. An authentication means 98, after it is authenticated as bona fide during the authentication acceptance period, computes a unidirectional function value for the authenticator from the program execution means 97, and compares the computed value X with data Y stored previously concerning the program execution means 97. The authentication means 98, if X equals Y, authenticates the program execution means 97. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To prevent cutoff of a system caused by a problem of electric power supply from a battery. SOLUTION: This computer device is constituted to connect a main battery 60 for performing charge-discharge with a second battery 61 for performing charge-discharge, and receives supply of electric power from the main battery 60 and the second battery 61. An embedded controller 41 is equipped in the computer device, and seizes residual capacity at a temperature of the second battery 61 at discharging time by receiving information from a CPU 66, and receives supply of the electric power from the main battery 60 by switching the second battery 61 to the main battery 60 when a seized temperature exceeds a prescribed temperature (for example, 55°C) and the seized residual capacity is less than prescribed capacity (for example, 20%).
