Methods are disclosed for manufacturing multi-layer film reflection mirrors, in which a desirable shape accuracy of a reflected wavefront can be obtained after locally scraping the multi-layer film. A connector plate is adapted to connect to a drive shaft of the vehicle and a clutch pack is mounted within the differential housing that interconnects the differential gear assembly and the connector plate. The conveying guide structure includes a first conveying guide extending in the second direction, and a second conveying guide connected from the first conveying guide at an end on the other side of the second direction and extends toward the other side of the second direction so as to curve in the first direction with respect to the first conveying guide. Examples of compounds of the invention include the compounds according to Formula Ia, or a pharmaceutically acceptable salt thereof, and the compounds of the examples. The compounds are useful in the treatment of an affective disorder, including depression, anxiety disorders including general anxiety disorder and panic disorder and obsessive compulsive disorder. In a specific embodiment, monochromatic blue or UV light output from a light-emitting diode is down-converted to white light by packaging the diode with fluorescent organic andor inorganic fluorescers and phosphors in a polymeric matrix.
