Abstract: <P>PROBLEM TO BE SOLVED: To provide a "device drive system and device access method" for improving the performance of a device capable of performing high speed access.  <P>SOLUTION: In this device drive system, at least two devices (HDD, DVD drive) and a host device are connected to a bus, and the prescribed device is accessed by the host device so that data transfer can be performed between the host device and the device. The prescribed amounts of data read from a first device (DVD drive) are stored in the buffer, and the data are successively read from the buffer at a normal speed so as to be reproduced. The host device monitors whether or not the amounts of unprocessed data stored in the buffer are equal to or less than set amounts, and when the amounts of unprocessed data are larger than the set amounts, the host device gives priority to the data transfer with the HDD, and when the amounts of unprocessed data are less than the set amounts, the host device performs data transfer with the DVD drive.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Failure diagnostic device and program
Inventor: ADACHI KOJI
IPC: B41J29/38
Filed: 2008-02-18
Abstract: <P>PROBLEM TO BE SOLVED: To enable updating of a diagnostic model not only on a regular basis but also in an unscheduled fashion in conformity with actualities of failure situations in a market when a failure diagnosis is performed using a causality network.  <P>SOLUTION: A threshold of update processing is determined on the basis of the number of failures and a failure occurrence rate (S120). Even when it is not update time, it is determined whether a conditional probability table is updated or not on the basis of the threshold (S130-S152). For instance, when the number of failures or the occurrence rate becomes the update threshold or more, it becomes a candidate for a target of an unscheduled update (S150-YES). When the number of failures or the occurrence rate becomes less than a certain-fold of the update threshold, the update threshold is kept certain-fold (S152-NO, S154). When the number of failures or the occurrence rate is more than or equals to the certain-fold with respect to the update threshold, weighting coefficients concerning the number of failures are adjusted so as to be different from the certain-fold on a failure part-by-failure part basis (S152-YES, S156).  <P>COPYRIGHT: (C)2009,JPO&INPIT
