Abstract: In a preferred embodiment of the invention, a mirror antiscratch protector case mountable on a dental mirror, having a spaced-away recess portion of an interior concave wall surface with spaced-apart points on the interior concave wall surface on each of opposite sides of the recess portion supportable of mirror bezel structure of mirror mounting structure, and having a biasing spring positioned to press a mounted dental mirror's mirror bezel structure against the spaced-apart points, and having a barrier structure pressing against a leading edge of the mirror bezel structure when the mirror is mounted within the protector case such that the reflective surface of the mounted mirror is retained opposite the recess portion, with opposite edges of the protector case in alignment with the spaced-apart points converging from a wide to narrow width of the protector case such that varying sizes of dental mirrors are received and such that narrower portions of the concave wall surface serve as the barrier structure.

Abstract: In a preferred embodiment, there is provided an earring having a squared-cross-section post for extending through a pierced earlobe, and having a drainage channel formed in an upper surface thereof extending axially longitudinally of the elongated length of the post, and there being an anchoring structure and mechanism thereof for clamping with a slight twisting pressure onto the fastening-end of the post thereby providing enhanced clamping against accidental disengagement.

Abstract: High-precision, fine-detail forgings are formed from a workpiece material having superplastic forming characteristics by utilizing high strain rate forming to impart the bulk of the total deformation required and superplastic relatively low strain rate forming to impart detail and approach final tolerances in the product.
