Title: Infrared gas analyzer
Inventor: ENDOU MASASHI
IPC: G01N21/61
Filed: 1983-03-29
Abstract: PURPOSE:To compensate an interference portion automatically and in a short time by a method wherein the interference portion of a component to be measured which overlaps the output of a memorized component to be measured is determined from the rate (K value) of the interference of the component to be measured in another component to be measured which is calculated from the output of the interference portion and the output of the component to be measured. CONSTITUTION:In the first step, the apparatus is set in a test mode. First, the outputs E1-En of detectors D1-Dn are memorized respectively. Then, the rate (K value) of the interference of a test gas in the output of another detector is computed and memorized for each detector. In the second step, the apparatus is set in a measurement mode. First the outputs E1'-En' of the detectors D1-Dn are memorized respectively. Then, the output E/K of an interference portion contained in each of the outputs E1'-En' is determined on the basis of said memorized rate of interference. Subsequently, the output of the interference portion is subtracted from each of the outputs E1'-En' determined before, and thus the outputs EM1-EMn of components to be measured which are free from interference portions are calculated.

Furthermore a special pattern is added on the disk surface for access and set previously in a synchronizing area together with said synchronizing mark. While the position of a meandering pit or a special pit is previously changed for detection of the detailed information on the track position. Thus the tracking signal and the clock information can be detected with high reliability out of the prepit meandering right and left and also to detect the optical spot phase information.

Filed: 1984-03-22
Abstract: PURPOSE:To know whether or not a submarine and a school of fish contacts an antisubmarine net in water or sea by using an optical fiber as a sensor and obtaining variation in the quantity of traveling light from its breaking and deformation. CONSTITUTION:Optical fibers 2 and 3 from the ground passes through the sea or water as an optical submarine cable 8 to reach an optical fiber branching device 9, which sends light to the antisubmarine net 1 like a power distribution board and also sends return light to the optical fibers 2 and 3. For example, a submarine contacts or strikes the antisubmarine net 1 or is caught, the optical fibers 2 and 3 fitted to the submarine net 1 deform or break owing to the deformation or breaking of the antisubmarine net 1. When the optical fibers are broken, the quantity of light decreases almost to zero, which is detected. When the fibers deform, on the other hand, a scatter loss is generated owing to bending including a microbend. Variation in the quantity of light with the loss is detected by the detector 10.
