| titleOfInvention | Apparatus for measuring optical refractive index of liquid |
| abstract | PURPOSE:To make it possible to detect only the change in optical refractive index, which is yielded by the change in the component of liquid itself, highly accurately, by controlling the amount of light from a light emitting with a temperature sensitive element, which is attached to a structure. CONSTITUTION:A space, in which an optical fiber 1, a light emitting element 2, a photodetector 3 and a temperature sensitive element 4 are attached in an ink tank structure 8 is provided. Then the curved part of the optical fiber 1 is inserted into a tank 7. The elements 2-4 are inputted into the space and fixed to the structure 8 with a bonding agent and the like. The inserted part of the optical fiber 1 in the tank 7 is tightly sealed. Thereafter, the terminal of each element is connected to a pattern on a PCB 5. The PCB 5 is fixed to the structure 5. As a result, the temperature of the structure 8 becomes the approximately same temperature of ink liquid 9 since the structure 8 and the tank 7 form a unitary body. Therefore, the temperatures of the elements 2-4, which are attached in the structure 8, also become the approximately same temperature as the temperature of the liquid. Thus the characteristic of the temperature of a measuring system accompanied by the change in the temperature of the liquid can be compensated. Therefore, only the changing amount in optical refractive index caused by the evaporation of water content can be measured highly accurately. |
