    Abstract: PROBLEM TO BE SOLVED: To provide a ball auto-balance system control method for an optical disk device, to be applied to all auto-balance systems.
    SOLUTION: The ball auto-balance system control method for the optical disk device is provided with a spindle motor and a rotor for housing at least one ball, and includes the steps of: setting the acceleration/deceleration range of the spindle motor between a first rotational speed and a second rotational speed; performing acceleration/deceleration within the acceleration/deceleration range at least twice by driving the rotor by the spindle motor; obtaining a signal error value generated by the optical head of the optical disk device after the acceleration/deceleration of the spindle motor within the acceleration/deceleration range; and controlling the spindle motor to accelerate up to an operation rotational speed when the signal error value is smaller than a predetermined value.

    Abstract: PROBLEM TO BE SOLVED: To provide a keyboard structure which is excellent in the portable convenience and the efficiency of an operation where key intervals are adjustable.
    SOLUTION: This keyboard structure is provided with at least a substrate, a plurality of key modules, a piezoelectric element and a differential device. Each pair of key modules are arranged symmetrically to a horizontal direction on the substrate with reference to a horizontal axial center line S of the substrate. The piezoelectric element is connected to the key modules so that an electric signal can be outputted. The differential device is provided with at least one differential element and at least one movement control unit, and a pair of key modules are interlinked by adding a horizontal force, and moved close to or apart from the horizontal axial center line S of the substrate so that the corresponding movement control unit can be interlinked by the key modules, and that the other key modules can be moved close to or apart from the horizontal axial center line S of the substrate.

    Abstract: PROBLEM TO BE SOLVED: To provide a method to detect a lost status report which is deterministic and adaptive to the transmission conditions of a communication system.
    SOLUTION: The method to detect the lost status report determines that a second status report is required when an AMD PDU not negatively acknowledged in the first status report, an AMD PDU with a polling bit set, or the last negatively acknowledged AMD PDU is received after the expiry of a roundtrip timer and before all the negatively acknowledged AMD PDUs in the first status report are received. The method provides a deterministic way of detecting a lost status report, resulting in improved transmission throughput in a wireless communications system.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for avoiding deletion of new key set in an Inter-RAT procedure and wireless equipment relating thereto. SOLUTION: The wireless equipment first normally completes any Inter-RAT procedure of Inter-RAT delivery, Inter-RAT cell re-selection or Inter-RAT cell change instruction from UTRAN. The wireless equipment than determines presence/non-presence of USIM. When the USIM is present, the wireless equipment determines whether or not the new key set is received and whether or not the key set is used for an encryption function and an integrity function in the case of current RRC connection. When the new key set is present but is not used, the wireless equipment stores a value of zero in the USIM as a security START value for a CN domain associated with the RRC connection.
