Abstract: PURPOSE:To increase the recording capacity by providing a clock circuit having a frequency double as high as that of a variable frequency oscillator into a control circuit and carrying out the writing/reading operations with a frequency double as high as that of a buffer circuit. CONSTITUTION:A data separating circuit 1 demodulates the data of an MFM form received from an interface into the data of an NRZ form and records temporarily the demodulated data to a buffer circuit 2. A VFO clock circuit 4 has a frequency double as high as the clock received from an interface and modulates the data recorded to the circuit 2. Then an R/W control circuit 5 performs the data reading/writing operations with a frequency double as high as the clock of the interface and demodulates the read data into the NRZ form. An NFM read data generating circuit 8 turns the data stored in the circuit 2 into the data of the MFM form with the frequency of the clock of the interface. Then the data of the MFM form equivalent to two tracks of the interface are alternately recorded in time division for each sector on a single track of a magnetic disk. Thus the recording capacity increase a double.

IPC: G06F15/16
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To obtain expected parallelism and to permit fast inquiry. SOLUTION: This parallel database system is constituted by connecting a front-end server(FES) 7, a back-end server(BES) 73, an input/output server(IOS) 70, and a disk 80. The number of processors of the FES 75, BES 73, and IOS 70 and the number of disks of the disk 80 and its division number are determined according to a load pattern. For example, FES:BES:IOS:disk = 1:4:1:8. Further, scalable system constitution is obtained by increasing and decreasing the number of BESs between at least one set and up to four sets according to load variation. Further, when the BESs are increased or decreased, data are not moved and only management information is moved. Consequently, expected parallelism is obtained and a fast inquiry process is actualized. The scalability of the system can be actualized.

Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To correct an exhaust gas recirculation amount to proper value by a simple configuration even when pressure dispersion is caused in the intake system and exhaust system of an internal combustion engine. SOLUTION: On condition that a diesel engine 11 is in idling state, the respective pressures of an intake pipe 30 can be detected by a pressure sensor 30a installed on the intake pipe 30, when a final duty ratio command value for driving an electric vacuum regulating valve 40a for exhaust gas recirculation(EGR) becomes [0%] and this duty ratio command value becomes a prescribed command value determined for idling previously.
