Title: Locked group detector
Inventor: TSURUOKA KEIICHIROU
IPC: H04N5/76
Filed: 1978-02-15
Abstract: PURPOSE: To detect a locked group by delaying a portion of the reproduced signals, which are reproduced from a disc-shaped recording medium, for a time reguired by the one turn of the recording medium and by comparing the resultant delayed signals with the reproduced signals left undelayed.  
     CONSTITUTION: In a device for reproducing a disc-shaped recording medium 1 which has its surface helically recorded, the reproduced signals from a pickup 2 are demodulated through a signal processing circuit 4. These signals are added as timely delayed signals through a delay circuit 5 to a comparison detecting circuit 6, where they are compared with the signals left undelayed. When the condition of locked group is reached, the pickup means 2 repeatedly traces an identical signal groove. The signals to be taken out of the pickup means 2 are repeated each time reguired by one turn of the recordig carrier 1 so that the undelayed signals become similar to the delayed signals. As a result, the output of a differential amplifier 7 is reduced to zero voltage.

Abstract: PURPOSE: To make it possible to enlarge and reduce a recording picture by making it possible to vary the generation period of pulses sampling picture data and then by forming a recording picture of the size in inverse proportion to the generation period.  
     CONSTITUTION: With switch 6 closed, selector circuit 5 selects clock pulses of period T2 from terminal (b) to halve the period of sampling pulses.

Similarly, data  are sampled, n by n columns, to form a recording picture composed of picture elements of M rows by N columns. Therefore, the recording picture is enlarged twice  laterally and lateral resolution increased twice. Thus, a recording picture of any size  can be obtained by varying sampling pulses.

Abstract: PURPOSE:To automatically diagnose the area of a fault caused by the secular change of a logical element, etc., by accelerating or decelerating the applying cycle of the action timing signal to execute again a diagnosing program in the case the diagnosing program is over normally to a suspected device. CONSTITUTION:The action timing signal generating means 121-12n are prepared to the devices 111-11n respectively. A diagnosing control means 20 gives an instruction to a clock control means 40 to change the output cycle of the action timing signal within an allowable range when a diagnosing program is over normally to a suspected device. The means 40 controls selectively the means 121-12n for the suspected device based on the received instruction. Then the action timing signal generating means of the suspected device accelerates or decelerates the output cycle of the action timing signal under the control of the means 40. Thus it is possible to automatically diagnose the area of a fault which is accidentally caused by the secular change of a logical element, etc., in a normal operation state.
