Title: Concentration measuring method of oxygen and dissolved oxygen
Inventor: TAKAHASHI AKIRA
IPC: G01N27/26
Filed: 1983-11-01
Abstract: PURPOSE:To improve the measuring accuracy of oxygen concentration, by performing temperature compensation for the output of diaphragm electrode by the Arrhenius equation since the oxygen diffusing coefficient in the film of the diaphragm electrode changes in accordance with the Arrhenius equation. CONSTITUTION:It is well known by the Arrhenius equation that the oxygen diffusion coefficient in the film of a diaphragm electrode is increased with the increase in temperature. Based on the Arrhenius equation, temperature compensation for the output current of the diaphragm electrode is performed. At first, the electrode is placed in the air at an absolute temperature T1. When the output current becomes a steady state, the current I1 and the temperature T1 are memorized. The electrode is placed in the air at an absolute temperaure T2, and the current I2 and the temperature T2 are memorized by the same way. The measured values are substituted into the equation logI=A-B(1/T), and coefficients A and B are obtained. Then the electrode is put in a gas to be checked. The output current and the absolute temperature are measured, and the measured values are substituted in the equation. Thus the oxygen concentration of the gas to be checked is measured.

Filed: 1986-09-02
Abstract: PURPOSE:To prevent a polycrystalline silicon film from being peeled in a melting process and to enable crystal growth to be performed up to a range distant from a seed part, by selectively forming a silicon oxide film in a part where a silicon substrate is etched to form a groove as deep as the groove. CONSTITUTION:A silicon oxide film 22 and a silicon nitride film 23 are formed on a single-crystal silicon substrate 21 and a pattern is formed by the use of photo-lithography so that the film 22, the film 23, and the substrate 21 are selectively etched. Successively, a resist film 24 is removed and a groove 25 is oxidized and moreover a silicon nitride film 23' is formed and thereafter the film 23' is etched. Thus, the film 23' formed on a side wall of the groove 25 remain on the side wall of the groove 25. Finally, after a silicon oxide film 22' is formed on the groove, the films 23 and 22 existing on the step are removed. When a polycrystalline silicon film or an amorphous silicon film 13 is formed, no step occurs between the seed part 14 and the silicon oxide part 12. Therefore, when the film 13 is melted by laser in radiation, stress is not applied to this part, so that a trouble such as peeling of the film 13 does not occur.

Filed: 1986-09-04
Abstract: PURPOSE:To compute the water content of a dehydrated cake continuously with accurate and continuous detection of moisture, by measuring the thickness of the cake with a sensor mounted on a support base continuously while a gap maintaining device is mounted on the sensor to keep a gap constant. CONSTITUTION:A measuring sensor 5 and arms 6 and 7 are pivotably attached on a fixed support base 4 and a link 8 is pivoted between the arms. A driven plate 9 is provided at the lower end of the arm 6 in contact with the surface of a dehydrated cake 1 while a moisture meter sensor 10 not in contact with the cake 1 at the lower end of the arm 7 in such a manner as to spin freely. As the thickness (t) of the dehydrated cake 1 varies with a parallelogram link mechanism, the plate 9 is driven and the sensor 10 measures moisture of the cake 1 continuously with a fixed gap L1. A clearance L2 between the plate 9 and the sensor 5 varies in inverse proportion to the thickness (t). The measured values are converted into electrical signals and moisture/thickness (t) is computed to calculate a water content. Thus, the water content of the cake can be learned continuously and accurately in a very short time.
