Title: Measurement of total nitrogen
Inventor: ARIMOTO HIROZOU
IPC: G01N30/08
Filed: 1980-03-17
Abstract: PURPOSE:To measure a total amount of nitrogen continuously and quickly by a process which comprises reductive decomposition of a sample in contact to turn N compound to NH3, absorption of NH3 into a strong acid solution, and a high chromatography of a certain amount of the absorption solution in which the fluorescence strength is measured with addition of a fluorescence emitting reagent to the eluting liquid thereof. CONSTITUTION:A sample is introduced into a sample boat 10 from a sample introduction part 9 of a contact reductive decomposer 1, and H2 fed thereinto from a hydrogen cylinder 2. The boat 10 is sent to a decomposition part 11 with a control bar 8 to decompose the mixture with a heater 17. The mixture thus decomposed is reduced with a catalyst 12 on a support to turn N compound to NH3. Acid gases as by-product (H2S, HCl and the like) are absorbed with an acid gas absorbent 13 while NH3 is absorbed into a strong acid solution in an ammonia trapping section 15. A certain amount of the absorption liquid is introduced into a column 21 of a high speed chromatograph from a sample introduction part 20. The moving phase 18 is sent to the column 21 while an elution liquid is reacted with a fluorescence emitting liquid 22 in a chemical reaction tank 24 to measure the fluorescence strength with a fluorescent photometer.

Filed: 1984-02-24
Abstract: PURPOSE:To avoid the disturbance of the head height relation due to a drop-out by comparing the data on the writing start of an optional truck with the set value by a comparison means to decide the data as the omission value data when the data is smaller than the set value and replacing said data with the second data. CONSTITUTION:The writing start data D1i of an optional track obtained by the scan of a head 11A, for example, is supplied to a data comparison means 73 from an input terminal 71 and compared with the prescribed value K. When the D1i is smaller than the value K, the omission value due to a drop-out is decided. Then the D1i is replaced with the second data D2i of the same track by a data replacing circuit 75. The data D2i is delayed by a prescribed time tau compared with the data D1i. When the D1i is larger than the value K, no drop-out is decided with no replacement carried out for the data. A subtraction means 76 obtains the difference between the data D1i and the data D1,i-1 preceding by a field. This error data is converted into analog signals by a D/A converter 65 and extracted through an output terminal 58 as a position control signal of a BM head. In such a way, the head height relation is never disturbed.

Abstract: PURPOSE:To enable the position of a laser beam to be detected even during laser working, by providing a plurality of optical sensors on the side of an aperture opposite to the laser beam emitting side thereof and outside of the periphery of the aperture. CONSTITUTION:An outer diameter of a laser beam is limited by an aperture 11. Generally, a Gaussian beam whose radial distribution of intensity is normal distribution is selected. The laser beam trimmed by the aperture 11 enters into a plurality of optical sensors 100. When output of each optical sensor found when the laser beam has been initially set so as to pass the center of the aperture 11 is compared with output of the optical sensor found when the laser beam is deviated to upside in the aperture 11, for example, the output of the latter case is higher than the former. By detecting such increase in output in the optical sensors, any movement of the laser beam can be detected. In this manner, the position of the laser beam within the optical resonator can be always detected properly, so that the intensity of laser beams can be prevented from being distributed unsymmetrically to cause defects in works.

Abstract: PURPOSE: To discriminate only the data required to be read and stored by setting each standard mark in both the X and Y directions of an image sensor and comparing the size of the standard marks with that of a mark got a reading position.
