Hangers are provided for mounting a variety of items, such as, for example, paper items, objects, decorative lights, and seasonal d\xe9cor items, on target surfaces, namely surfaces to which electrostatic materials are adherent, including surfaces such as smooth and non-porous surfaces, windows, mirrors, metal surfaces, glossy surfaces, and the like. A right-to-left change-over linkage connects the shift rod emanating from the driver’s gear selector lever to the shift lever on the left side of the replacement transmission. Thus-configured semiconductor laser is allowed to successfully suppress the area of the p-n junction plane to a small level, and to obtain a high level of reliability, because there is no need of processing the center portion of the quantum dot active layer, contributive to laser oscillation. The complexes may include targeting molecules.
