Title: Method for quantitative analysis of component in capillary tube type uniform velocity electrophoretic analysis
Inventor: HINE TAKASHI
IPC: G01N27/26
Filed: 1985-06-12
Abstract: PURPOSE:To enable the quantitative analysis of a component in fine tube type uniform velocity electrophoretic analysis reduced in an error, by detecting the length of a separation zone on the basis of the timewise analytical value of a zone detection signal. CONSTITUTION:When a specimen is injected from a specimen injection port 2 to operate an apparatus, the specimen is separated at every component, that is, corresponding to the magnitude of ion mobility in a capillary tube and migrated to a potential gradient detector 4. The detector 4 outputs the potential signal corresponding to the mobility of a component to an integrating circuit 7 which, in turn, inputs the signal from the detector 4 to outputs the timewise integrated value of a potential gradient signal. Because this integrated value is the product of the mobility of the ion forming a separation zone and the length of said separation zone and the electric conductivity of each component is known, the length of the separation zone, that is, the amount of the component in the separation zone is calculated. As mentioned above, because the length of the separation zone is detected on the basis of the timewise analytical value of a zone detection signal, the length of the separation zone can be accurately measured regardless of the change mode of the zone detection signal and the enhancement of separation accuracy is enabled.

Abstract: PURPOSE: To detect anomaly rapidly and certainly by directly detecting the variation of operation cycle when operation anomaly is generated in a fluid pressure equipment.  
     CONSTITUTION: In a sensor 13, the air pressure as the signal which is output from an air passage 28 on the output side is reduced by the exhaust pulsation from the air discharge port 24 of a plunger pump 11. Accordingly, an air system operating valve 38 is opened at each exhaust time by the air pressure described above, and outputs the air from a purified air source 35 to a pressure switch 39. As a result of this, the conversion circuit 14 whole outputs electric pulse at each exhaust time. This pulse is, after counted in a counter 47, compared with the standard signal from a standard signal generator 48 in a comparison circuit 49. When the pump 11 runs idle and the exhaust and the exhaust cycle is shortened, the count of the counter 47 in a same time increases, exceeding the standard signal. Thus, signal is outputted to an output circuit 52 from the comparison circuit 49, and relay 51 is operated, and an alarm 50 is operated.
