PURPOSE:To entirely eliminate causing flaws and cracks to the glass and make the processing of bulbs in a high temperature possible by transmitting the vibration of a vibration transmitter to the body to be removed with dust through a macromolecular film. CONSTITUTION:A macromolecular film 15 is interposedly arranged between a sealed bulb 11 and a vibration transmitter 14. By this arrangement the ultrasonic vibration from the vibration transmitter 14 is transmitted to the sealed bulb 11 through the macromolecular film 15 without directly contacting the surface of the sealed bulb 11, so that the possibility of causing flaws and cracks to the glass is entirely eliminated and even if the sealed bulb 11 is in a high temperature, the interposition of the macromolecular film relaxes the thermal shock in the process, also eliminating causing cracks to the glass due to the thermal shock. |
