A radiation induced light wavelength shifter and an apparatus for detecting radiation and transmitting detected signal through an optical fiber are disclosed. A radiation induced light wavelength shifter used in such apparatus comprises a cylindrical scintillator, a fluorescent optical fiber an end of which is inserted into the scintillator, the fluorescent optical fiber extending out of the scintillator, a light shielding member covering the scintillator and the fluorescent optical fiber, and a light reflecting material covering the scintillator.

A fuzzy controller is provided which enables even an unskilled operator to easily adjust various conditions in a glass pipe sealing process. The fuzzy controller has a fuzzy control processor including an image processing unit for processing and calculating image information as a softened state change value of the glass pipe and a combustion state value of burner flame, and a fuzzy control processing unit for calculating and outputting, by receiving a result of this calculation, a suitable control value for controlling parameters relating to the burner flame by fuzzy inference. The fuzzy controller may further has a fuzzy diagnosis support processor which, if there is an abnormality in the sealed portion of the glass pipe and if the state of the glass pipe after sealing is input to the manipulation instruction data input support processor by the operator, automatically ascertains the cause of the abnormality by using fuzzy inference and displays it on a CRT. A fuzzy control system and a fuzzy control process are also provided which enable automatization of a lamp glass pipe sealing process by using this fuzzy controller.
