Title: Composite electrode for internal liquid automatic supplying type
Inventor: ITO YOSHIHARU
IPC: G01N27/403
Filed: 1988-05-24
Abstract: PURPOSE:To make it possible to build an internal liquid tank in a composite electrode, so that the total structure of said composite electrode is made compact and easy to handle with, by fixing a water absorbing core material to an upper end of a communicating pipe section to extend through said communicating pipe section, a projecting pipe section and an electrode tube approximately to a connecting section of liquid. CONSTITUTION:An internal liquid in an internal liquid tank 3 is taken into a communicating pipe section 19 through either one of communicating holes 6, 7. The internal liquid is then guided along a water absorbing core material 20 into an internal liquid container 12 within an electrode tube 1. On the other hand, the air in the container 12 flows upward from a vent hole 18 of a projecting pipe section 17 in the communicating pipe section 19 to be discharged out of either one of the communicating holes 6, 7 to the tank 3. Two or more vent holes 18 are formed, so that the internal liquid, even if it remains by the surface tension between the core material 20 and the projecting pipe section 17, can escape from one of the vent holes. As a result, even when the communicating holes 6, 7 are formed adjacent to each other, the core material 20 becomes easy and ready to absorb the internal liquid. Further, the internal liquid in the container 12 is easily guided to a connection section 8 along the core material 20. Therefore, the distance between the communicating holes 6, 7 can be made short, and the length of the connecting section 8 can be shortened by the core material 20.
