A measuring apparatus for measuring a counterbore hole chamfer depth of a workpiece, includes a positioning member having a guiding hole aligned with the counterbore hole of the workpiece, a support member having a receiving hole aligned with the guiding hole, and a measuring device supported by the support member. A first cylinder mounting bracket extends in the longitudinal direction and has at least one aperture disposed along the length of the bracket for locating and securing the hydraulic cylinder to a structure. The plurality of first-axis sensing lines are formed by laser etching a first conducting layer, wherein each first-axis sensing line at least has a first output pin. The board lock device comprises a retaining plate retained in the cavity and substantially parallel to the PCB mounting face of the base portion and a lock plate perpendicularly extending from the retaining plate beyond the PCB mounting face of the base portion for locking with the PCB. An active-matrix liquid crystal display device including the liquid crystal composition is also described. In a preferred embodiment, this disruption is created by administration of LHRH agonists, LHRH antagonists, anti-LHRH receptor antibodies, anti-LHRH vaccines or combinations thereof.
