Title: Agc circuit
Inventor: SAKURAI HIROSHI
IPC: H04B1/10
Filed: 1990-02-21
Abstract: PURPOSE:To obtain a stabilized video AGC circuit protected from the influence of noise by detecting a synchronizing signal part from a video signal, digitizing the detected signal part and then outputting an AGC voltage. CONSTITUTION:The AGC circuit is provided with a synchronizing separator circuit 12 for separating a synchronizing signal from a video signal and a PLL circuit 11 for generating a clock pulse signal whose phase coincides with that of the synchronizing signal and the 1st clock pulse signal is applied from the circuit 11 to an A/D converter 2 to sample the synchronizing signal and convert the signal into a digital signal. The 2nd clock pulse signal is applied from the circuit 11 to a D-FF 3 to detect the maximum value data of the synchronizing signal level, the 3rd clock pulse signal is applied to a 2D-FF 4 to detect the minimum value data of the synchronizing signal level and the 4th clock pulse signal is applied to an up/down counter 9 to drive the counter 9. Since the output of the D/A converter 2 is not changed, the input voltage of the gain control terminal of a video amplifier 1 is not changed and the output of the amplifier 1 is not changed until the output of the counter 9 is changed, the AGC circuit is driven.

Title: Magnetic recording/reproducing device
Inventor: SUDA SEIJI
IPC: G11B5/027
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To record digital data of large scale and various kinds of information by converting digital data into an information signal constituted of a signal area, synthesizing the information signal and a sound signal and recording a synthesized signal in a recording medium. SOLUTION: At the time of recording digital data, a modulator 20 converts digital data into the information signal constituted of the signal area of a prescribed frequency. The information signal is synthesized with the sound signal by a mixing circuit 22 and is converted into the synthesized signal. A recording amplifier 13 records the synthesized signal in the recording medium. At the time of reproduction, a high fidelity head 7 reads the synthesized signal from the recording medium and the synthesized signal which is read is separated into the sound signal and the information signal. The separated information signal is demodulated and digital data is reproduced. Much information data is written and recorded in a magnetic tape without interfering the sound signal and the video signal.

Abstract: PURPOSE: To surely operate an escalator automatically only when there is someone actually using it by providing a user detection means on a handrail belt and a motor actuation means for actuating a driving motor in response to a user detection signal which the user detection means outputs. CONSTITUTION: A certain microvoltage is constantly applied to a handrail belt 3 made of a transparent conductive sheet, and changes in the microvoltage due to human touch are detected by a detecting circuit 4. When a user standing on the landing of the escalator 1 touches the handrail belt 3, time detecting circuit 4 detects the voltage change and outputs a detection signal to a motor control circuit 6, which in turn actuates a driving motor 2 to start the operation of the escalator 1. After the user takes his hands off the handrail belt 3 on arriving the lower story, the detecting circuit 4 detects no voltage change and outputs no detection signal. Then a timer 5 operates, and after the elapse of a predetermined time outputs a time-up signal to the motor control circuit 6 to stop the driving motor 2.
