A precision gyroscope includes a gyroscope, means for receiving an external clock reference, and circuitry coupled to the means for receiving the external clock reference and adapted for stabilizing a temperature and a frequency of the gyroscope. A rear faceplate is connected to the front faceplate such that the rear faceplate is recessed from the front faceplate and access to the rear faceplate is provided through one of the lateral openings. Additionally, diskette assemblies may be provided within the platens that permit sub-samples to be separated without directly handling the tissue sample. The shoe sole may also include heat moldable materials so that it can be anatomically formed to the foot. The pad has odor and moisture adsorbing properties and the vamp includes at least one aperture proximate to the pad for permitting moisture and odor to diffuse through the at least one aperture and contact the pad. It is proposed that the surface layer reduces the boundary surface friction between the coating agent film and the overflow surface.
