Title: Tracking controlling circuit
Inventor: SHIBUYA TOSHIFUMI
IPC: H04N5/7826
Filed: 1984-02-15
Abstract: PURPOSE:To obtain a tracking controlling circuit which does not make any malfunction at the time of drop-out and to eliminate a blind section, by detecting frequencies of large and small azimuth loss effects and discriminating whether it is a blind section or drop-out by using both detected pulses. CONSTITUTION:When a head traces a track A1, on which the pilot signal of frequencies fP and fB of large and small azimuth loss effects is recorded, one level is added to a terminal 18 and an AND circuit 16 is turned on. Then the crosstalk component of adjacent tracks appears in the output of an LPF4 and BPF10 in addition to the fP and fB of the A1 track. Outputs of the LPF4 which detects the fP and the BPF10 which detects the fB are compared with thresholds at comparators 15 and 12 through envelope detecting circuits 5 and 11 and the voltage of a supply voltage 23 is outputted as an erroneous voltage by selecting the 24B side of a switch by outputs of fall detecting circuit 19 and rise detecting circuit 13 through an RS latch 22. When the pilot signal lacks due to a scratch, etc., the RS latch 22 is not reset and previous data are held.

Title: Shutter controlling circuit incorporating dimming signal circuit of flash
Inventor: NAGAOKA SHINJI
IPC: G03B7/16
Filed: 1981-02-23
Abstract: PURPOSE: To realize daylight synchronization, by emitting flashlight synchronously with the closing action of a shutter and using a photodetecting circuit for shutter control as a dimming signal circuit.  
     CONSTITUTION: A time-constant capacitor 10 is charged with a constant current by the output of a photoelectric element 3. When this charged voltage exceeds the reference voltage of a comparator 12, an electromagnet 13 is cut off to close a shutter and to start its operation. The transistors TR8 and TR7 are turned on with a TR4 turned off by the output of the comparator 12. Thus the charging is discontinued. When a flash trigger switch 27 is closed synchronously with the shutter closing action, the signal is latched at an FF circuit 29 to turn on a TR29. At the same time, the TR8 and TR7 are turned off with the TR4 turned on, respectively. Then the charging of the capacitor 10 is started again by receiving the reflected light of a subject caused by flash. When the charged voltage exceeds the reference voltage of a comparator 14, an SCR24 is turned on to discontinue the emission of light.

Title: Tension and plate thickness conrolling method
Inventor: KONDO KATSUYA
IPC: B21B37/18
Filed: 1985-02-12
Abstract: PURPOSE:To improve product quality by obtaining a necessary tension controlling value based on a thickness of a rolled material, while subtracting an equivalent tension value related to plate thickness change from the tension controlling value to obtain a tension modifying value, and adjusting reel motor currents based on the gained tension modifying value. CONSTITUTION:Thickness meters 6a and 6b are set on the inlet and outlet sides of a reversible 4 stages rolling mill 1, respectively. A feed forward controller 7 and a feed back controller 8 are also set on the mill 1. An output saturation device 11 provides high and low saturation limits for plate thickness control and armature currents of the reel motor are controlled by corresponding high and low limit values when the tension modifying value exceeds the saturation limit. A necessary tension controlling value is obtained by thickness measurements by thickness meters 6a and 6b, while a tension value equivalent to a reduction modifying value is subtracted from the tension controlling value to obtain a tension modifying value. The current of reel motors M2 and M3 is adjusted based on that tension modifying value. In this way, the accuracy of tension control is increased and the product quality is improved.
