Filed: 1989-12-08
Abstract: PURPOSE:To correctly reproduce a signal regardless of a bad quality of the signal by using plural discrimination windows whose phases are shifted from one another to simultaneously discriminate and reproduce the signal and discriminating even a bit, which has the phase locally shifted, so that it can be correctly put in a discrimination window. CONSTITUTION:A pulse 2a corresponding to the peak of the signal reproduced by a head 20 is generated by a waveform processing circuit 1 and a pulse converting circuit 2 and is inputted to a PLL 3 and plural discriminating circuits 4. Discrimination windows synchronized with the pulse sequence of the pulse 2a are generated in the PLL 3 and are inputted to plural discriminating circuits 4 as discrimination windows 6a to 6c whose phases are slightly shifted from one another by a delay circuit 6. Discriminating circuits 4 generate discrimination data 4a to 4c corresponding to discrimination windows of respective phases. Consequently, even a bit which has the phase locally shifted is so discriminated that it can be correctly put in discrimination windows 6a to 6c. Thus, the signal is correctly reproduced regardless of a bad quality of the signal.

Title: Multiple reflection optical device and reflection mirror tilting mechanism
Inventor: ISHII NORIYOSHI
IPC: G02B17/00
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce a spatial margin for positional deviation by calculating the tilt amount of a 1st reflection mirror from the detected position of an optical path and controlling the tilt of the 1st reflection mirror in accordance with the tilt amount so that closed loop control may be constituted. SOLUTION: Reaction light 3 is propagated to a downstream side while it is repeatedly reflected on the reflection mirrors 1a and 1b, and the position of the optical path of the reaction light 3 transmitted through the reflection mirror 1a is observed by a position sensor 16. When the reaction light is positionally deviated, the positional deviation is detected by the positional deviation sensor 16, and the tilt amount of a tilt mechanism for correcting the positional deviation is calculated by a signal processing part 17. Furthermore, the elongation/contraction amount of an actuator incorporated in the tilt mechanism 19 for obtaining the necessary tilt amount is obtained by a driving part 18, and the actuator is driven. When a signal from the driving part 18 is inputted, the actuator is elongated and contracted.  After all, the reflection mirror 1b is tilted until positional deviation output from the sensor 16 becomes zero. Thus, the reaction light 3 is always transmitted to a fixed position.

When the current DC voltage is higher than the preceding value and the current output power is lower than the preceding value, a mans 1 updates the target DC voltage to a lower value, because such a target DC voltage is too high, and when the current DC voltage is lower than the preceding voltage and the current output power is higher than the preceding voltage, the means 1 updates the target DC power to a higher value, because such target value is too low and a DC voltage comparing means 13 controls the increase or decrease of the amplitude of the reference waveform, so that the DC voltage becomes the updated target DC voltage until the next prescribed time elapses. With the repetition of such a process, the target DC voltage is trial controlled.
