Abstract: PURPOSE:To make it possible to perform the micro-analysis for underwater total nitrogen with high sensitivity with the decreased influence of co-existing salts and suspended matter by using an autoclave, reduction reaction vessel provided with heating means, electronic cooler and chemiluminescence type nitrogen oxide analyzer to make prescribed analysis. CONSTITUTION:A sample is taken into a measuring pipe 5 from a sample vessel 1 by an air pump 2 and after 100ml is measured, the sample is sent through a mixing pipe 6 to the autoclave 7 where a soln. mixture composed of peroxodisulfuric acid K and NaOH is added to the sample and the sample is subjected to a heating treatment. The treated soln. is measured to 50ml in a cooling and measuring tank 18 and 20ml is drawn in a remeasuring pipe 16. The drawn soln. is sent to the heated reduction reaction vessel 19 where sulfuric acid, ferrous ammonium sulfate and ammonium molybdate are added to the soln. The formed NO is sent through the electronic cooler 20 to the nitrogen oxide analyzer 21 by which the emission intensity is measured. The measured intensity is compared with the chemiluminescence intensity of a reference soln. and is converted to the concn. of total nitrogen which is then recorded.

Title: Osteoporosis diagnostic system
Inventor: ISHII TETSUYA
IPC: A61B8/00
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To accurately estimate the state of bone density and to easily perform a highly reliable diagnosis. SOLUTION: Ultrasonic impulses are repeatedly radiated towards the cortical bone of a patient and echoes from the cortical bone are received. Reception signals are converted to digital echo signals by an A/D converter 8 and an echo level is detected by a CPU 11. The CPU 11 extracts a maximum echo level from the echo levels detected during a measurement period and calculates the acoustic impedance of the bone based on the extracted maximum echo level. Then, the bone density of the patient is calculated from the, calculated acoustic impedance of the bone. Since the acoustic impedance of the bone is expressed by the square root of [elastic modulus × density] of the bone, when the bone density is reduced and the elastic modulus is lowered, the acoustic impedance of the bone receives the synergistic effect, sensitively responds and is substantially reduced.  Thus, the acoustic impedance of the cortical bone becomes an excellent index in terms of judging the bone density.
