A congestive placement preventing apparatus, applied in a logic circuit layout having 2K logic circuits, where K is a positive integer, is provided. As a result, the attenuation ratio of the attenuator fluctuates, and it is difficult to process the substrate with the homogeneous irradiation energy. The passage is shaped and sized to control a sealed flow of liquid to the nozzle and has a tapered region connected to the exit port to frictionally engage and retain a tubular inlet of a spray paint nozzle in a sealed relationship. In fusion bonding both the fusion bonding parts, a bonding flash accommodation part is defined on one side of the fusion bonding parts by an associated pair of shoulders and another bonding flash accommodation part is defined on the other side of the fusion bonding parts by another associated pair of shoulders. The data on the chip card are read by a writing and reading unit of the respirator.
