Disclosed are compounds having non-steroidal anti-inflammatory drugs covalently linked to a phospholipid moiety via a bridging group. The aperture further comprises a second waveguide comprising a third protrusion and a fourth protrusion, each protrusion extending longitudinally along one side of the second waveguide. The high amplitude resonant vibration of the fan blade causes formation of a high velocity unidirectional flow stream. In a terminal connecting step, the unified core wire portion is press-contacted or press-fitted to the terminal.
