Title: Measuring instrument for depth of underwater moving object
Inventor: NAKAI HIROSHI
IPC: G01S7/52
Filed: 1989-03-07
Abstract: PURPOSE:To eliminate the compensation of sound speed influenced by a water temperature and to accurately measure the depth by emitting an ultrasonic signal at the same elevation angle and depression angle from an underwater moving object, receiving a return wave from the water surface and the water bottom, and executing an operation, based on each distance thereof. CONSTITUTION:Transmitters 2a, 2b emit an ultrasonic wave at an elevation angle theta2 and a depression angle theta1 (=theta2), respectively, and a reflected signal which is reflected by the water surface and the water bottom and returned is received by receivers 3a, 3b, respectively. When distances at the time of its return are denoted as S2, S2, respectively, its ratio becomes a ratio of the water depth D and the depth H1. Subsequently, when a ratio of the distances S2, S1 is determined, the depth H1 and H (=D+H1) can be calculated when the water depth D by a pressure sensitive type water depth meter 6 is known. In this state, a time counting means 4 and a Doppler displacement frequency measuring means 5 derive necessary time t2, t1 and Doppler displacement frequencies fd2, fd1 with regard to the same ultrasonic signal. A first arithmetic means offsets a factor of a sound speed and shows a ratio of the distances S2, S1 as a function of the time t2, t1 and the frequencies fd2, fd1. Next, the depth H1, H is calculated by a second arithmetic means 10.

Title: Drop-out compensating circuit
Inventor: SENSOU HITOSHI
IPC: G11B20/06
Filed: 1987-03-10
Abstract: PURPOSE:To improve the capability of drop-out detection by generating a drop- out detection signal at the time of detecting that the time of crossing of high frequency signal to a prescribed reference level is longer than a prescribed time. CONSTITUTION:When an RF signal is inputted, the rise or fall point of time of the output pulse train signal of a limiter amplifier 8 is a zero-crossing point of time of the RF signal. A zero-crossing detecting circuit of a drop-out detecting part 2 generates a zero-crossing pulse signal in accordance with this point of time. If drop-out occurs and the time between generation of one zero- crossing pulse and that of the next zero-crossing pulse exceeds a prescribed time, a frequency detecting circuit 10 inverts the output level. Thus, drop-out is surely detected. A changeover switch 6 normally outputs a video signal but outputs the video signal of one horizontal period 1H before by a 1H delay circuit 7 at the time of detecting drop-out.
