Abstract: A lock device for a box includes a locking shaft, a lock shell, a lock core, a limiting unit, and a key. The lock shell has a surrounding shell wall that confines a core-receiving space, and that is formed with an insert hole in spatial communication with the core-receiving space to permit removable extension of the locking shaft into the core-receiving space. The lock core is disposed movably in the core-receiving space, and has a surrounding core wall that confines a key compartment and that is formed with a shaft engaging unit. The lock core is rotatable in the lock shell between locking position and unlocking positions. The limiting unit limits rotation of the lock core in the lock shell. The key is inserted removably into the key compartment and is operable so as to drive rotation of the lock core between the locking and unlocking positions.

The engaging protrusion includes a head body that has opposite top and bottom ends and that gradually reduces in cross-section from the top end to the bottom end. The bottom end of the head body is formed with a curved nose that protrudes downwardly therefrom and that is blocked by the stopping protrusion when the second rail is moved frontwardly to a front position relative to the first rail. The head body is elastically deformable so as to be compressed by the stopping protrusion to an extent that the nose is able to slide over the stopping protrusion when the second rail is further moved frontwardly from the front position by a pulling force.

Abstract: A mechanism for confining a flat flexible cable of an image scanner in position is provided. The flat flexible cable is electrically connected between a circuit board and a carriage and bends differentially with the movement of the carriage relative to the circuit board under a scanning platform. The mechanism includes a confining member disposed between a first portion of the flat flexible cable and the scanning platform for isolating the flat flexible cable from the scanning platform. The confining member changes states and bends differentially with the movement of the carriage relative to the circuit board under the scanning platform, and has a bending resistance greater than that of the flat flexible cable. Accordingly, the confining member is kept at least a certain clearance from the scanning platform while confining the first portion of the flat flexible cable thereunder.

Abstract: The present invention provides an electrical discharge machine (EDM) with double-axis double-speed linear motor mechanism for fast machining operation. In this EDM the tool fixture assembly is driven by a linear motor, whiles the work piece platform assembly is driven by another linear motor in the opposite direction. Applying no contact direct drive, such as linear motors, eliminates wear problem in ballscrews in conventional embodiments and enhances availability of the machine. Opposite and double motors drive configuration not only increases relative speed between the tool electrode and the work piece, but also stabilize the speedy jump operation by canceling reaction force of tool electrode movement.
