Title: System and method for preparing automatic marker
Inventor: CHIYAARUZU AA MAATERU
IPC: A41H3/00
Filed: 1995-01-24
Abstract: PURPOSE: To provide a system and method for automatically making a marker by which the formation of a new marker is facilitated by utilizing existing marker design. CONSTITUTION: A marker analogous to a marker to be formed is selected by retrieving a computer data base of the existing markers. When the existing marker satisfies the criterion for forming the user-specified marker, the marker is recognized to be 'an analogue'. Corresponding pieces are arranged and oriented in the new marker by using the data of the positions and the orientations obtained from the pattern pieces of the analogous marker. Thereafter, the new marker is compressed by using a soft ware routine, and the whole new pieces are simultaneously nested without nesting the pieces one by one or two by two. The compression routine corrects the overlapping of pieces and guarantees the most efficient nesting of the new pieces.

Title: Optical disk record reproducer
Inventor: KOJIMA TADASHI
IPC: G11B7/09
Filed: 1983-02-21
Abstract: PURPOSE:To perform the tracking servo easily and satisfactorily by detecting a position where no pit exists as a signal corresponding to the total reflection level and shifting equivalently a photodetector to set the detector at the center of a reflected beam. CONSTITUTION:Two output signals P1 and P2 are delivered from split regions which are combined variably and receive the peak wave detection through the 1st and 2nd peak wave detecting circuits 13 and 14 respectively. Then the position of a reflected beam spot is decided from the output of the 2nd comparator 16 to produce the switch signal needed for a switching control circuit 18. A synthetic switch circuit 12 is changed over to give an equivalent shift to a photodetector as a whole so that the spot of the reflected beam is aparently set at the center of the photodetector. The output of the 1st comparator 15 is supplied to the 3rd comparator 17 to be compensated by the output of the comparator 16, i.e., the detection signal for no-pit position. Thus the tracking error signal free from offset is supplied to the driving part of an optical system. Then the satisfactory tracking servo is possible.

Abstract: PURPOSE:To obtain a good control system by performing oversampling and raising a sampling frequency. CONSTITUTION:An FG pulse having a frequency proportionate to a rotary frequency of a motor 9 is generated from an FG 1, and this period is converted into a digital value by a sampling circuit 2 and an FV converter 3, and then a difference from a target value is subtracted by a subtractor 4 to be as a speed error signal. This is added with a phase error signal by an adder 22 to be as a capstan error signal. This digital signal is converted into a pulse width modulation (PWM) signal, which is then turned into an analog signal through a low pass filter (LPF) 7, so as to be impressed upon a motor driver 8 to drive the motor 9. The sampling frequency is raised by an oversampling circuit 20 to a sampling frequency of a speed system, and a base band component and a frequency component of the sampling frequency after oversampling are only extracted by a filter 21, and are added with the speed error signal by the adder 22. By this method, a high speed, stable and good control system can be obtained.
