A sliding hitch with a self-arming latch is described. A seal face treatment process has been developed using seal ring machining equipment which has a laser unit that forms micro-topography depth features in the seal face and then performs a material surface treatment process to selectively alter the conductivity of the seal face so as to virtually eliminate electro-corrosion in the seal rings. This one-to-one correspondence between the defect image and the live display enables precise marking of the physical sample since the user looks at the distorted live image of the sample, not the physical sample itself, during the marking process. In one embodiment, the gradient interface area is formed of lateral spatial gradient structures for narrowing the cross section of a value from the micron to the nanometer length scale. The mounting system has a laser carrier, a top clamping bracket and two lower clamping brackets which fixedly capture the bow stabilizing bar therebetween. The MOSFET device has a very high channel carrier mobility, while maintaining a very low leakage junction.
