Abstract: PURPOSE: To provide a method by which a leaking point can be detected quickly and inexpensively from a pipeline by detecting the fluctuation of the acoustic level with the passage of time of sounds produced in pipes and detecting the leaking location from the fluctuation of the acoustic level. CONSTITUTION: The interior of one pipe 5 of a pipeline 1 is emptied so that leakage detecting tests can be given to the pipe 5 and the section to be tested is selected and sealed by opening or closing a valve 6. Then, the pipe 5 in the section to be tested is evacuated with a pump 2.

When the acoustic level does not rise, but stays at the same level, it is judged that pipeline 1 shows no leaks. When the acoustic level rises, it is judged that the pipeline shows leaks, when the test is successively repeated by narrowing the section to be tested, the existing section of the leakage can be specified finally.

Title: Washing method for base of electrophotographic sensitive body
Inventor: YOSHIDA AKIRA
IPC: G03G5/05
Filed: 1991-04-19
Abstract: PURPOSE:To allow washing which does not adversely affects human bodies and local environment without decrease of the electrophotographic characteristic by washing a base with water specified in temp. and dissolved oxygen quantity. CONSTITUTION:A stage for washing the base with the water specified to at least >=40 deg.C and <=1ppm dissolved oxygen quantity is provided. Since the base is washed by mainly using the water in such a manner, the residues of halides by a hydrocarbon halide solvent are not generated and since the base is treated at >=40 deg.C warm water, the removal of the impurities sticking on the surface of the base is easy. Further, since the dissolved oxygen quantity participating in an oxidation reaction is confined to <=1ppm and the oxidation reaction does not nearly generates and the surface characteristic of the base is made uniform, therefore, the formation of the uniform photosensitive body is possible. Further, the adverse influence of the oxide films on electrophotographic characteristics is substantially eliminated. The washing water having <=10mus electrical conductivity is more effective. The surface of the base is thus washed without changing the properties thereof.
