Title: Information reproducing device
Inventor: SATOMURA SEIICHIRO
IPC: H04L7/10
Filed: 1992-02-19
Abstract: PURPOSE:To improve the interchangeability between a device and a recording medium by delaying the start of a synchronous operation for a reproducing signal for the prescribed time from the head of a storing region and generating the correct synchronous clock for the reproducing signal surely in a storage region. CONSTITUTION:A counter 20 counts a clock while making a sector arc detection signal S1 detected by a SM detecter 1 as a reference point, the detecting position is delayed e.g. by one byte from the head position of the pattern of the counter 3 while considering variation factors. The detection signal S10 from the counter 20 is sent to a circuit for generating PLL gate signal 7 and the PLL gate signal S11 is generated. Since the head position detection signal S10 is outputted while delaying by one byte, the signal S10 rises while delaying by one byte. Consequently, the synchronous operation for the reproducing signal in the synchronous clock generating circuit 8 is started while delaying by one byte without fail. Thus, the operation is not locked to the other frequency.

Title: Pseudo lock detection circuit for costas loop type demodulator
Inventor: IWASAKI JUN
IPC: H04J13/00
Filed: 1989-03-22
Abstract: PURPOSE:To output a pseudo locking detection signal by applying synchronous detection to a signal with a frequency component appearing at the output of a multiplier multiplying the multiplication output of Ich and the multiplication output of Qch of a COSTAS loop type demodulator demodulating a phase- modulated carrier at the pseudo lock of the COSTAS loop type demodulator. CONSTITUTION:When a COSTAS loop type demodulator 20 is locked normally, since the level of an output signal S8 of a multiplier 25 of the COSTAS loop type demodulator 20 is nearly zero, the value of the detected signal S10 is nearly zero. On the other hand, when the carrier frequency of an input modulation signal S5 is shifted by the integer multiple of the bit rate of the data transmission in the increasing direction more than the oscillated frequency of a VCO 27 of the COSTAS loop type demodulator 20 and the pseudo lock state takes place, the level of the detected signal S10 reaches a prescribed level TH or above. Thus, the pseudo locking state of the COSTAS loop type demodulator is detected.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: TATARA YUSUKE
IPC: F02D43/00
Filed: 1994-04-08
Abstract: PURPOSE:To effectively avoid fuel malfunction of air-fuel mixture caused by EGR gas at the changeover of the air-fuel ratio by decreasing an EGR gas circulation rate when a target air-fuel ratio is changed over, and decreasing a fuel injection rate after making the computed residual EGR gas rate decrease less than a specified value. CONSTITUTION:Provided are fuel injection valves 81-84, an EGR gas circulation rate control means M2, a target air-fuel ratio setting means Ml and a fuel injection rate control means M4. A residual EGR gas rate computing means M3 calculates a residual EGR gas rate in an intake system. The EGR gas circulation rate control means M2 decreases the EGR gas circulation rate when the target air-fuel ratio setting means M1 switches the target air-fuel ratio. The fuel injection rate control means M4 starts deceasing the fuel injection rate after making the residual EGR gas rate decrease less than a specified value, which gas rate is computed by the residual EGR gas rate computing means M3. It is thus possible to prevent occurrence of fuel malfunction and misfire without changing the air-fuel ratio to a lean condition where the residual EGR gas rate is large.
