Title: Monitoring device for inside of treating tower
Inventor: KURAMOTO KENJI
IPC: B01J47/14
Filed: 1980-03-10
Abstract: PURPOSE: To monitor the inside of a resin regeneration tower extremely efficiently and safely by  disposing a color difference detector consisting of a light projecting part and a photodetecting part  vertically movably along the monitoring tower on the side wall of said tower, and installing a  reference color detector in a suitable place of said side wall.   
     CONSTITUTION: Irradiation light λ is radiated from the tip of an optical fiber 9, is condensed 10,  and is sent through a transparent body 6 into the ion exchange resin 2 in a regeneration tower.  The reflected light reflected from the resin 2 at the spectral reflectance specific to the color thereof  is passed through the body 6, is condensed 13, and is sent via a visual sensitivity filter 14 to a  photoelectric transducer 15, by which it is converted to an electric signal. This signal is further  sent from a photodetecting signal line 16 to a display part. In this case, a color difference detector  19 consisting of a light projecting part 11 and a photodetecting part 12 is vertically moved along  the monitoring window 6 disposed longitudinally on the side wall 1 of the regeneration tower, and  the photodetecting signal corresponding to the color of the resin in the arbitrary position of the  window 6 is ouputted to the line 16. On the other hand, a reference color detector 27 operates in  the same manner as the detector and the photodetection signal obtained in correspondence to the  separated resin in the earliest stage in the regeneration tower is used as a reference signal for the photodetection signal obtained with the detector 19.

Abstract: PURPOSE:To enable the heating treatment with highly pure hydrogen while preventing deterioration in degree of vacuum within a growth chamber due to introduction of the hydrogen, by providing a hydrogen supply pipe which can directly apply the hydrogen only to a molecular beam source and further providing a shielding plate at the inlet port thereof. CONSTITUTION:A hydrogen valve 3 is opened to a molecular beam source 1 whose temperature has been previously increased, so that hydrogen is introduced via a bellows 14 into the source 1 through a hydrogen supply pipe 10.

All molecules of the beams from the source 1 are adhered on the bottom face 11a of the shielding plate 11 but not on a hydrogen inlet port 12. Thus the cleaning operation of the molecular beam source 1 is not adversely effected in any way. The hydrogen is introduced to such an extent that the degree of vacuum within a growth chamber 2 becomes in the order of 10<-3>torr. This means that the molecular beam source 1 can be cleaned with one-thousandth of hydrogen in comparison with prior arts.
