A storage device being one of a plurality of storage devices storing data includes a memory and a processor coupled to the memory. The processor executes determining, when having received a new request and a new priority information during a preparation for an execution of another update processing, whether a new priority indicated by the new priority information is higher than a priority of the update processing in the preparation. The process including canceling the update processing in the preparation when having determines at the determining that the new priority is higher than the priority of the update processing in the preparation. The process includes forwarding the new request and the new priority information to another storage device when having determined at the determining that the new priority is higher than the priority of the update processing in the preparation.

In an air bag having a structure wherein part of the gas generated from a gas generator inside the air bag is released so as to absorb an impact force on a human body, the present invention provides an air bag type protector for occupant including at least one auxiliary bag from storing the released gas, fitted outside a foundation cloth of the air bag. The apparatus of the present invention makes it possible to reduce the size and weight of a filter device inside the gas generator and hence, to reduce the size and weight of the gas generator as a whole. The auxiliary bag is preferably fitted in such a manner that the upper half of the foundation cloth of the air bag is covered therewith.

The activity monitor (100) includes a basic information acquisition unit (20) that accepts input of basic physical information (BA) of the user's body, a target information acquisition unit (30) that accepts input of the user's target physical expenditure (CS), an activity pattern acquisition unit (40) that acquires pattern information indicating the user's intent on the activity amount (AM), and a target activity calculation unit (50) that determines a target activity amount (TA) on the basis of the basic physical information (BA), the target physical expenditure (CS), and the pattern information acquired by the activity pattern acquisition unit (40).
摘要:
A method for measuring bromate ion is provided that provides high-sensitivity measurement results more simply and more quickly than conventional bromate ion measurement methods. A fluorescent substance that is quenched by coexistence with bromate ions is added to a sample 130 and the fluorescence intensity of the fluorescent substance after quenching is measured, the measured fluorescence intensity being subtracted from the fluorescence intensity of a standard sample containing no bromate ions to calculated the fluorescence intensity difference. The bromate ion concentration is calculated from the calculated fluorescence intensity difference, using a pre-determined calibration line between the fluorescence intensity difference and the bromate ion concentration.

An internode put requesting unit detects a time-out with respect to a put request issued to the next node in the order of a multiplexing chain and notifies a put/get executing unit of the time-out. The put/get executing unit sends an error to the previous node in the order of the multiplexing chain or a client and instructs a put-failed-data synchronizing unit to synchronize data failed to be put, and the put-failed-data synchronizing unit performs a synchronization process. A primary makes other put requests wait until completion of the synchronization process. Furthermore, when having received the error, the client issues a get request to the tail end of the multiplexing chain.
