Title: Chroma level control circuit
Inventor: TADAMI MITSUSHIGE
IPC: H04N9/793
Filed: 1979-07-25
Abstract: PURPOSE: To ensure the control for the reproduction property of the chroma signal with the outputs of the capacitors, by providing the circuit which compares the reproduced chroa level with the reference level plus plural numbers of capacitors which give a time division to the comparison result and then hold the result.  
     CONSTITUTION: The change pattern of the standing wave type and having a comparatively low speed in the field direction is stored in memory circuit 17 comprising capacitors C 1 ∼C 16 . The output of circuit 17 is supplied to the plus input of operational amplifier 34 through switch circuit 16, buffer circuit 29 and LPF40 each to be added to the output of comparator 8 which compares the reproducd chroma level and the reference level. The output of amplifier 34 is supplied to the RF equalizer through switch 19 in the form of control voltage VC. As a result, the amplitude frequency property of the RF equalizer is controlled to the comparatively high-speed fluctuation of the chroma level in the line direction as well as to the standing wave type fluctuation in the field direction each. Thus the chroma level becomes steady to obtain a high-quality reproduced picture screen.

IPC: G01N29/11
Filed: 1983-05-27
Abstract: PURPOSE:To detect a non-metallic inclusion in small steel securely on-line by adopting an attenuation method transmitting an ultrasonic focusing beam vertically from a probe to a steel sheet and fetching the bottom surface echo succeeding to the 2nd bottom surface echo received from the sheet. CONSTITUTION:A liquid tank 20 is filled with a liquid 22 and the probe 24 and the steel sheet W are dipped into the liquid 22. The sheet W is arranged vertically to a beam axis. An ultrasonic focusing beam 24a projected from the probe 24 to be used for both transmission and reception is propagated in the liquid 22 and partially reflected on the surface of the sheet W to obtain a surface echo S. On the other hand, the transmitted beam is reflected by the inclusion 16 or the bottom to obtain defective echos F1-Fn and the bottom surface echos B1- Bn. When said method is to be applied to the sheet W having especially thin thickness, the bottom surface echo attenuating method setting up a gate range 28 to the echo succeeding to the 2nd bottom echo B2-Bn is devised. Consequently, a small non-metallic inclusion in the steel can be securely detected on-line.

Abstract: PURPOSE:To perform desired detecting operation accurately by providing plural sensor units and a common bus between an interface and a clock circuit. CONSTITUTION:Detection signals from the sensor units 1A are applied to the interface (IF) 2 through the common signal bus 5 and an address signal based upon the clock signal from the clock circuit 4 is applied to address circuits of the units 1A through a common clock bus 6. Then when the set value in a circuit 10 matches with the address signal, only the corresponding unit 1A is connected to the IF 2. Further, the sampling signal from the circuit 4 and the address signal are applied to the IF 2 and a combination of the address signal corresponding to the selected unit 1A and the address signal corresponding to the unit 1A is applied to a CPU 3 through the IF 2. The interference among sensors is therefore eliminated by transmitting various signals by a bus system while assigning the time for operation to the plural units 1A individually.
