A polyaxial pedicle screw includes a housing, a bone screw member, and an anvil. The bone screw member includes a head and a threaded shaft extending from the head. The head is selectively securable within the housing. The anvil is positionable within the housing adjacent to the head of the bone screw member when the anvil and the head of the bone screw member are positioned within the housing. The anvil may define one or more grooves in an outer surface of the anvil. The groove defines a flap that is flexibly attached to the anvil to enable the anvil to flex an amount sufficient to maintain the head of the bone screw in constant contact with the anvil when the bone screw member is moved relative to the anvil.

A improved liquid crystal display device including two substrates each having transparent electrode thereon disposed in parallel while keeping a predetermined gap by means of pillar-shaped spacers and a liquid crystal held between said first and second substrates is proposed. In the liquid crystal display device, density or volume of the number of the pillar-shaped spacers provided in the off-display area is higher than those of a density of the number of said pillar-shaped spacers provided in the display area. This change is made continuously or stepwise along areas. The spacers are preferably disposed so that a contact area between the spacer and a rubbing cloth during the rubbing process is minimized, or so that an orientation defective area caused starting from the spacer does not extend into the pixel area, or so that a plurality of spacers are disposed along a flow of liquid crystal from filling port into the gap between the first and second substrate.

A gun magazine speed loader that can load an entire magazine simply by pulling the magazines external follower in a downward motion. Rimmed cartridges are aligned nose down and side-by-side in a loading channel and the magazine and speed loader are then tipped up toward a vertical position with the magazine below the loader. By passing the stream of cartridges through an “articulator” that articulates the nose of the cartridge and feeds cartridges ‘rim-first’ and up through feed lips and into the magazine, the cartridges fill the magazine in a continuous stream, essentially at the speed of gravity-falling cartridges under control of the external follower. The articulator has no moving parts and operates with rimmed cartridges and with curved or low-rake angle magazines having an external follower.
