Title: Ultrasonic measuring device
IPC: G01N29/44
Filed: 1992-03-19
Abstract: PURPOSE:To provide an ultrasonic measuring device which can measure a reflection function in one direction on a sample surface and can obtain the sound velocities of transverse wave, longitudinal wave, and surface waves in that direction. CONSTITUTION:A burst wave which is generated by a transmission part 1 is converted to an ultrasonic wave by a transducer 4 and then an ultrasonic beam which is focused linearly at a sample 9 is transmitted. The ultrasonic wave which is reflected by the sample 4 is converted electroacoustically and then complex information of the received signal is taken out by multiplying parts 10 and 11, a phase-shifting part 12, and LPF's 13 and 14 and is stored in a memory 17. Fourier transformation is performed by a computer 18 and a control part 20 based on the complex information for calculating spectrum, thus obtaining the reflection function in one-direction and elastic properties such as Poisson ratio and modulus of elasticity for each direction.

Title: Measuring chamber for sulfurous acid detector
Inventor: SATO TAKESHI
IPC: G01N27/416
Filed: 1991-03-28
Abstract: PURPOSE:To enable accurate and quick measurement of the concentration of sulfurous acid in a liquid to be measured by setting a measuring chamber with a flat roughly truncated cone-shaped container erected while a inflow port is provided below a conical surface and an outflow port thereabove. CONSTITUTION:A detecting section, a transfer pump 101, a three-way valve 102 and various controllers 103 containing control circuits are mounted in a case 100 of a sulfurous acid detector. A measuring chamber 300 is supplied selectively with a liquid to be measured in a sample bottle 104 and a buffer liquid in a buffer liquid bottle 105 through the three-way valve 102 from an inflow port 33 and the liquids are drained to a drain bottle 106 at an outflow port 34. When the liquid to be measured is supplied to the measuring chamber 300 and a proper temperature is kept, bacteria B oxidizes sulfurous acid in the liquid to be measured to consume oxygen in the liquid. Thus, the oxygen in the liquid is lowered to decrease the amount of the oxygen reaching an oxygen electrode as oxygen detecting section of an oxygen battery. This lowers the output of the oxygen battery thereby enabling the conversion of the concentration of the sulfurous acid from the drop ratio of the output.
