摘要:
In a demodulator for demodulating a BPSK modulated signal, demodulation performance degradation caused by analog circuits such as fabrication variation is suppressed, and furthermore, frequency variation in the BPSK modulated signal is followed by the demodulator. A multiplication circuit 105 multiplies a carrier, generated from a BPSK modulated signal by a carrier information extraction circuit 101 and a carrier generation circuit 102, by a digital BPSK modulated signal obtained by digitizing the BPSK modulated signal by an A/D converter 104 via a LPF 103. A carrier period integration circuit 106 integrates the multiplication result with respect to the period of the carrier, and the integration result is then binarized in a discriminator 107, thereby realizing demodulation.

A disk storage system containing a storage device having a record medium for holding the data, a plurality of storage sub-systems having a controller for controlling the storage device, a first interface node coupled to a computer using the data stored in the storage sub-systems, a plurality of second interface nodes connected to the storage sub-systems, a switch connecting to a first interface node and a plurality of second interface nodes to perform frame transfer therebetween based on node address information added to the frame. The first interface node has a configuration table to store structural information for the memory storage system and in response to the frame sent from the computer, analyzes the applicable frame, converts information relating to the transfer destination of that frame based on structural information held in the configuration table, and transfers that frame to the switch.

Disclosed is storage system, that is, an array-type disk apparatus which is provided with an error monitor section which monitors the status of error occurrence in a disk drive and instructs initiation of mirroring between the disk drive and a spare disk drive when the number of errors occurred of the disk drive exceeds a specified value, and a mirror section which performs mirroring between the disk drive and spare disk drive. Storage system, that is, the array-type disk apparatus may be provided with an error monitor section which monitors the status of error occurrence in a disk drive and gives such an instruction as to set the status of the disk drive in a temporary blocked state, and a data restoring section which executes data restoration by reading data from the temporary blocked disk drive when reading from another disk drive constituting a disk array group is not possible during data restoration. Further, at the time of shifting data from a disk drive to a spare disk drive, it is possible to store a failure counter indicating the number of errors occurred in the disk drive in a common memory and ensure selection of either reading of data of a data-shifting disk drive from the disk drive or reading data from some other disk drives constituting a disk array group and restoring data through redundancy. calculation.

摘要:
A heterogeneous computer system, a heterogeneous input/output system and a data back-up method for the systems. An I/O subsystem A for an open system and an I/O subsystem B for a mainframe are connected by a communication unit. In order to back up data from at least a disk connected to the I/O subsystem B in a MT library system and in order to permit the mainframe to access the data in the I/O subsystem B, the I/O subsystem A includes a table for assigning a vacant memory address in a local subsystem to the memory of the I/O subsystem A for an open system. A request of variable-length record format received from the mainframe is converted into a fixed-length record format for the subsystem B. The disk designated according to the table is accessed, and the data thus obtained is sent to the mainframe and backed up in the back-up system.

A trouble determining apparatus for a chopper type DC boosting circuit capable of determining whether or not a switching device is in trouble securely and quickly and when the switching circuit is in trouble, preventing other circuit from being in a trouble. Upon determining a short-circuit trouble of a transistor Q, a boosting circuit control unit 22 is turned OFF a power relay RL and then determines whether or not a voltage VP1 of a connecting point P1 rises over a first set voltage VS1 by the time when a first predetermined time t1 elapses since an ignition switch IG is turned ON with the transistor Q set to OFF. Upon determining an open trouble of the transistor Q, the boosting circuit control unit 22 determines whether or not the voltage VP1 of the connecting point P1 falls below a second set voltage by the time when a second predetermined time t2 elapses since the transistor Q is turned ON with the power relay RL set to OFF and whether or not the voltage VP1 falls from a state before the transistor Q is turned ON by more than a third set voltage.
