IPC: G01N29/00
Filed: 1991-12-18
Abstract: PURPOSE:To accurately obtain such a sound characteristic value as sound velocity in a measured object by accurately measuring the distance over which an ultrasonic wave propagates in the measured object. CONSTITUTION:Sound sensors 2a, 2b are arranged face to face at a known distance so that the center axes of them coinside. Then ultrasonic waves are transmitted and received in a water tank between the two sensors 2a, 2b and the distances between the two sensors and the measured object surface are measured with a measured object size meter 1. From this result and the distance of the two sensors, the size of the measured object is obtained, which is stored in a memory 11. After storing, ultrasonic wave is transmitted from the sensor 2a to the measured object and a reflected wave from the measured object bottom surface is received. Then, the time difference between the first and the second reflection waves from the bottom surface is measured and finally, by using this time difference and the size of the measured object store in the memory 11, the sound velocity C in the measured object is obtained with a sound characteristic meter 12. The result is output to an indicator 13.

Title: Block structure for fish breeding ground
Inventor: OISHI YOSHITETSU
IPC: E02B3/14
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To improve a function by storing a spacer which can be implanted in a cavity in the vertical direction to pass through a block main body and filling a plural number of filling clods on it. SOLUTION: A block for a fish breeding ground is constituted of a block main body 1 passing through a cavity 1a in the vertical direction on its center and provided with a channel port 1d to open to the outside by being communicated to it, a spacer 2 stored in the cavity 1a and free to implant on a river bed and a plural number of filling clods 3 to fill an upper end opening part of the cavity 1a by covering the spacer 2. At the time of the rise of water, flowing pressure of a water current to the inside of the cavity 1a is damped by the filling clods 3, and as inflow water from the channel port 1d is also large in channel resistance, the flowing pressure is buffed. Additionally, as flow of high flow velocity or turbulence is not generated in the inside of the cavity 1a, attached algae, etc., are also hard to peel off.  Consequently, it is possible to prevent sediment corrosion of a cavity bottom part, to prevent positional slippage and inclination of the block main body and to make an excellent fish breeding ground as the algae, etc., are not peeled off.
