IPC: G01N21/75
Filed: 1986-09-16
Abstract: PURPOSE:To prevent mixing of bubbles in an optical cell, by laying the optical cell beneath a bubbling cell, connecting the lower part of an inner tube and the lower part of an outer tube to both ends of the optical cell, and inserting a bubbling nozzle in the inner tube. CONSTITUTION:A gas, which is jetted from a bubbler part 22 at the lower part of an inner tube 23, climbs through the inner tube 23 in a bubble state and overflows onto the surface of liquid in an outer tube 22. Namely, the liquid in the inner tube 23 is brought up in the outer tube 22 in a bubble state. The liquid whose bubbles naturally disappear flows into an optical cell 33 through the slant lower side at one end of the optical cell 33 by way of a spiral flow path 31 and a communicating pipe 36. The liquid returns into the inner tube 23 from the slant upper side of the other end of the optical cell 33 through a communicating pipe 37. When the axial center of the optical cell 33 is lifted at the side of a photodetector by theta deg. from a light source lamp 38, disturbance of instruction due to the stagnation of the bubbles in the optical cell 33 can be prevented.

Title: Discharge lamp containing metallic sodium
Inventor: SUMITOMO TAKU
IPC: H01J61/22
Filed: 1994-09-14
Abstract: PURPOSE: To protect an electroluminescent tube from the leakage of sodium without using a fuse. CONSTITUTION: Together with mercury and xenon gas, metallic sodium is sealed in an electroluminescent tube 1. The electroluminescent tube l is put in the inside of an external tube 2. A protective element 3 made of silicon dioxide is put in the external tube 2 while being connected with the electroluminescent tube 1 in parallel. Sodium which leaks out of the electroluminescent tube 1 adheres to the surface of the protective element 3, so that current flowing in the electroluminescent tube 1 is lowered and the electroluminescent tube is sometimes extinguished or can not start. Since only a resistor with high resistance as a load is connected with an external circuit of such as a ballast by the protective element 3 in the case the electroluminescent tube 1 is not lighted, the external circuit can be prevented from being burned and damaged.
