Title: Method for diagnosis of deterioration of discharge electrode rod
Inventor: HAMADA SHINKO
IPC: G02B6/255
Filed: 1990-11-29
Abstract: PURPOSE:To properly decide the time for exchanging an electrode rod by taking the image of the side profile of a discharge electrode rod with using an optical fiber observation system for side profile, processing the transmission image of the rod to calculate the deposition amt. of SiO2 on the rod, and then judging the deterioration of the rod from this calculation. CONSTITUTION:The transmission image of the side profile of a discharge electrode rod 2 is observed with an optical fiber 1 and a microscope 4 which enlarges the image. This image is picked up by a camera 5 and the signals from the camera are converted by an A/D converter and then fetched into a memory IPU 8. Since the electrode rod 2 is made of metal and SiO2 depositing thereon is not transparent, the light incident to the side of the rod does not transmit the rod nor the deposite. The area S21 of the image of a new electrode rod 2 is preliminarily stored in the memory when the rod is exchanged. After repeating discharge, the area S22 of the rod 2 on which SiO2 deposits is measured and compared with S21. When S22 - S21 becomes a specified value or larger, the rod is regarded as deteriorated, and the system informs an operator with an alarm or monitor to exchange the rod 2.
