A projector is provided to ensure the enhancement of contrasts while reducing the needs for alignment accuracy. The imaging systems disclosed herein may include a reflective layer disposed proximate to and beneath a laser imageable layer on an optical disc. It is possible to realize a multi-layer capacitor which can satisfy both of the X7R characteristic and B characteristic of the temperature characteristic of the electrostatic capacity, has little voltage dependency of the electrostatic capacity and the insulation resistance, is superior in insulation breakdown resistance, and can use Ni or a Ni alloy as the internal electrode layer. The clutch jaw moves between the output drives and engages only one output drive at a time. The ground engaging tip may have a substantially keystone-shaped contour providing additional wear material at the top surface for use in top-wearing earth moving applications.
