Title: Device for measuring partial pressure of oxygen
Inventor: HENRII EDOWAADO KARURAA
IPC: G01N29/032
Filed: 1985-08-21
Abstract: PURPOSE:To measure highly accurately the concentration of oxygen by applying ripple magnetic field to normally-magnetized gas such as oxygen to generate an acoustic wave from the gas and detecting amplitude proportional to the intensity of the acoustic wave. CONSTITUTION:Mixed gas containing oxygen is charged from an inlet port 1 to a test room 2 and discharged from an outlet port 3. At that time, a connection wave or a pulse signal is applied to a solenoid coil 7 to form a ripple magnetic field. Consequently, the oxygen is pulled to a magnetic field area 9 because the oxygen is normally-magnetized gas. But, non-magnetic gas is not influenced. The oxygen absorbed to the area 9 creates disturbance of partial pressure and generates an acoustic wave 11. The acoustic wave 11 is detected by a detector 13 and the concentration of the oxygen is measured from the amplitude proportional to the intensity of the acoustic wave. Since the ripple magnetic field is applied to the normally-magnetized oxygen to detect the oxygen, the partial pressure of the oxygen can be measured highly accurately and this method can be effectively used for the measurements of contents of respiratory oxygen.

Abstract: PROBLEM TO BE SOLVED: To obtain an optical connector which is inexpensively producible and with which necessary high accuracy is obtainable by bisecting an internal housing part to a plate having ultra-high precision holes and a post housing part which does not require the high accuracy. SOLUTION: The plate 4 having the first holes 2 and second holes 3 subjected to an ultra-high precision treatment is assembled to the internal housing part 5 for the optical connector. The plate 4 forms the end on the plug-in surface side of the internal housing part 5. This end on the plug-in surface side is enclosed by a plastic material to form the rear housing part 6. Then, the rear housing part 6 acts to guide optical fibers but is not for precision positioning and this function is executed by the plate 4. The internal housing part 5 is built into the optical connector. The exact alignment of two pieces of the optical connectors by using precisely treated positioning pins is made possible by the precisely produced holes 2, 3.
