Title: Damage detecting method for roll of rolling mill
Inventor: KURAHASHI MOTOFUMI
IPC: G01M99/00
Filed: 1988-09-28
Abstract: PURPOSE:To make it possible to measure the form and the progressing state of the damage of a roll by detecting AE (acoustic emission) waves which are caused by the breakdown of the surface of the roll of a rolling mill, and integrating the amounts of generation of the AE waves based on the magnitudes of amplitudes. CONSTITUTION:Water 10 whose flow rate is constant is jetted toward the end surface of a roll shaft from a nozzle 3 to which an AE transducer 4 is attached. Then, the AE waves are transmitted through the roll 2, the water 10 and the nozzle 3 and received with the transducer 4. The AE signal is transduced into a minute voltage signal in the transducer 4. The signal is amplified 5. Noises are removed in a filter 6. The signal is processed in main amplifiers 7a and 7b. The amplifier 7a has a small amplification factor and recognizes only the AE waves having large amplitudes. The amplifier 7b has a large amplification factor and recognizes the AE waves having the small amplitude. The signals are counted in judging devices 8a and 8b by an event counting method and an oscillation counting method, respectively. The counted numbers are integrated from the start of the rolling of the roll 2 in counting devices 9a and 9b. When the accumulated counted number exceeds the limit value of rough surface, warning is issued.

Abstract: PURPOSE:To decrease the light losses of a liquid crystal panel so as to assure the brightness of a display body and to eliminate crosstalk so as to improve quality by providing a thin-film layer varying in coefft. of thermal expansion from reflection electrodes between a plane substrate and the reflection electrodes. CONSTITUTION:The diffusion reflection plate provided with the reflection electrodes on the plane substrate has the thin-film layer 2 varying in the coefft. of thermal expansion from the reflection electrodes 3 between the plane substrate 1 and the reflection electrodes 3. The reflection electrodes 3 are metallic thin films and are formed to have ruggedness for the purpose of diffusion reflection. The thin-film layer 2 consists preferably of org. matter and the reflection electrodes 3 may serve also as the electrodes for the display body. The production of the diffusion reflection plate is executed by depositing the reflection layer while heating the thin-film layer 2 formed on the plane substrate 1 and etching this reflection layer to form the reflection electrodes 3. The org. thin-film layer is wrinkled by a difference in the coefft. of thermal expansion between the org. thin-film layer and the reflection thin-film layer and the fine ruggedness necessary for diffusion reflection is simultaneously formed when the plane substrate 1 including the org. thin-film layer 2 is heated at this time.
