Title: Cmi decoding circuit
Inventor: NAKAMURA KEIJI
IPC: H03M5/12
Filed: 1988-09-08
Abstract: PURPOSE:To simplify the title circuit by detecting a CMI code, selecting a phase of a frequency division clock and using the frequency division clock so as to decode the CMI code. CONSTITUTION:AND circuits 8, 9 pass outputs from flip-flops 3, 4 in the timing of a positive fc clock (e) and an inverted fc clock (f) and output a pulse when '10' is detected. The pulse (c) is detected by a pulse number detection circuit 11, which discriminates an AND circuit outputting more number of pulses. Then a selector 10 selects the fc clock with a phase having more pulse number and the selected fc clock operates a flip-flop 12. Thus, an output (d) of an exclusive OR circuit 9 is outputted as an NRZ code (g) and the CMI decoding is attained by using a 2fc clock only and no reception identification recovery circuit or the like is required.

Abstract: PURPOSE:To decrease the generation of a jitter by controlling disk rotation so that the interval of an H signal at the time of regeneration becomes the same as a stipulated value through the use of the measured value of the H signal interval separated from a regeneration stationary signal when a disk rotates forward at one rotation or above. CONSTITUTION:A disk 2 is rotated at a constant speed, a still picture signal is regenerated with a head 3, amplified 4, and the signal is sent to an H signal separating circuit 5 and is separated into an H signal used in the internal part and a regeneration stationary picture signal transmitted to the external part. In a delaying circuit 12, a delay signal V4 with an arithmetic value V3 delayed only for the time to substruct the lag time of an electric system and a mechanical system from the one-rotating time of the disk 2 is generated, and the signal is sent to an LPF15. In the LPF15, a control signal V1 to remove a high-frequency component from a signal V4 is sent to a motor driving circuit 16. Consequently, a high accuracy predictor can be obtained, and a jitter component less than the lag time of the electric system and the mechanical system can be eliminated by obtaining a new prediction value based on difference information obtained by the comparison between any H interval of a T times rotation and the stipulated value, delaying this predictor for one rotation, and using the predictor as a T + 1 times rotation controlling predictor.

Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To determine an angular rotational position of axial asymmetry of an optical PM fiber, etc. SOLUTION: Various angular positions around a longitudinal axis are irradiated during rotation (201). With regard to various angular positions, the difference between light beams passing the central section of a fiber end and light beams passing the outer side of the central section is determined to obtain the function of rotating angles. The curve of the function is analyzed to find out a valley region in which steepest ascending and descending exist (205). Only the region is used for determining an optical asymmetry (207 and 209). At this interval, the measurement points are more densely arranged and the curve becomes more accurate. Such the determination method is especially suitable to a PM fiber having a very small optical asymmetry as a fiber having an elliptical core.

Filed: 1989-09-01
Abstract: PURPOSE: To agree the number of clock pulses with the number of desired output periods by providing a resonator device, synchronous logic device, N- division counter device, feedback device and reference device. CONSTITUTION: A clock generator 14 is gate-controlled by periodic input pulses passing through a synchronous logic circuit part 12 and is used to drive an N-division counter (1st counter) 15. The 1st input of the N-division counter 15 receives a gate-controlled clock pulse signal from the clock generator 14, and the 2nd input receives a counted value N obtained by an N-counter (2nd counter) 16. A digital feedback loop gives the N-division counter 15 an appropriate value N by defining the N-counted value at the rate of one counting per input pulse. Thus, the number of clock pulses divided into N outputted during each input pulse period agrees with the number of desired output periods entered to a program input to establish a reference period counting.
