Abstract: A power system bus total overcurrent system is used with a part of a power system which includes two buses and first and second power line portions which extend between them. A protective relay system includes protective relays for each of the first and second power line portions, located near the two buses, wherein the relays determine the total current into and out of each bus.

In a current balance arrangement, the relays measure difference current using the same communication line arrangement between the two pairs of relays to determine a fault condition. Fault determinations are made in each case by the protection algorithms from total and difference currents.

Abstract: In a thermal-type airflow meter that measures an intake airflow rate in an internal combustion engine of an automobile or the like, there has been a problem that pulsation errors caused by external fluctuations under the environment including a large pulsation and reverse flow in the intake valve are difficult to be reduced.

Abstract: A flash memory includes an address information storage and a data write unit. The address information storage records address information about blank areas in a cluster consisting of a plurality of sectors. The data write unit writes, in response to a write request of data, data into at least one of the blank areas by referring to the address information about the blank areas. This makes it possible to solve a problem that occurs with a conventional flash memory. In particular, the number of erasable times of the improved flash memory is not limited to about one tenth of that of an EEPROM, and hence the improved flash memory can store frequently rewritten data.
