IPC: G06F12/12
Filed: 2002-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a method to copy data from a virtual tape server to another virtual tape server in a peer-to-peer environment. SOLUTION: Every time when a data set is modified or created, a flag is used for indicating whether the data set necessitates to be copied from a memory device to another. In one of the preferred implementation, when data is removed from a memory device based on LRU rule according to the time stamp of each data set, the time stamps of the data sets not copied are modified by adding some period of time to give priority to the not-copied data sets. Upon copying a data set, the time stamp is recovered to an ordinary one by reducing the same period of time that was added when a flag was given to the data set to indicate the necessity of a copy.

Title: Control method of brushless motor
Inventor: IWASAKI TAMOTSU
IPC: H02P6/06
Filed: 2002-06-07
Abstract: <P>PROBLEM TO BE SOLVED: To prevent unnatural correlation current from passing, for example, in PWM control of a brushless motor.  <P>SOLUTION: At the time of the initial start of timer processing, respective carrier cycles of a V-phase timer TMv and a W-phase timer TMw are set as respective delay correction periods tv1 (=t-tv) and tw1 (=t-tw) subtracted by respective timer starting delay components tv, tw for a carrier cycle (t) preset to a U-phase timer TMu. This can synchronize the carrier cycles of the respective phases from the second time onward with each other, so that its completion can be met so as to obtain no lags, even if the starting time of the respective phases of the carrier cycle at the initial start lags from each other. It is thus possible to prevent the unnatural correlation current from passing through in the PWM control.  <P>COPYRIGHT: (C)2004,JPO
