The D50 is the only entry-level Nikon DSLR to have the autofocus motor ('screw drive') built into the camera body, making the camera backwards-compatible with mechanical-drive autofocus lenses (Nikkor AF/AF-D series) dating back to 1989. This feature has been eliminated on later entry-level models and is currently only available on mid-range ...

In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed-chain movable linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. Spherical and ...
The primary distinction between types of rigid chain actuator is whether the actuating member is formed from a single chain or from a pair of interlocking chains in a back-to-back arrangement, like a zipper. Interlocking chain actuators have the advantages over single-chain actuators of improved resistance to buckling and that the actuating ...
A typical chain tool. With a chain placed on the central sprocket, the screw is turned until a pin is pushed from the linkage. A chain tool is a small mechanical device used to "break" a bicycle chain in such a way that it can be mended with the same tool.
Although the device did not transmit power continuously since the chains "did not transmit power from shaft to shaft, and hence they were not in the direct line of ancestry of the chain-drive proper", [4] the Greek design marks the beginning of the history of the chain drive since "no earlier instance of such a cam is known, and none as complex ...
