IPC: G01N21/23
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To measure concentration of a specific gas in mixed gas at a high speed and with high precision. SOLUTION: An analyzer 2 has an inspection chamber 4 into which sample gas is carried, and the sample gas passes through a first substrate 6 provided with a first coating 8 and a second coating 10. The second coating 10 is formed of a substance which absorbs specific gas selectively, and light beams 16 are radiated by being oriented so as to generate specific polarized lights by the substrate and coating from a light source 14, and the polarized lights of reflected light beams 18 changed owing to reflection in the coating and mutual reaction with the coating. This change is computed by a computation unit 22 by measuring the polarized light of the reflected light beams 18 in a light detector 20. The change of the polarized light generated by the absorption relates only to concentration of specific gas, and accordingly the gas can be identified.

Filed: 1991-12-13
Abstract: PURPOSE:To reduce the storage of the unnecessary operation recording of the start and stoppage of charging operation even when the start and stoppage of charging operation are repeated irregularly during the charging operation of grains. CONSTITUTION:When the passage of grains during the charging of grains is detected by an unhulled-rice flow sensor 6 when the charging operation of grains is conducted and a fixed time passes, a residue sensor 7' detecting the presence of grains is changed over and controlled under an ON state under the state, in which grains are detected, even under the state, in which grains are not detected. When the unhulled-rice flow sensor 6 detects grains and the fixed time passes, the residue sensor 7' is changed over and controlled under the ON state under the state, in which grains are detected, thus treating subsequent charging as additional charging, then reducing unnecessary operation recording.
