A method to reduce the width of slots or openings in a pipe. The method involve determining the position of the slots relative to the surface of the pipe and determining the width of the slots. A signal is generated corresponding to the determined width and relative position of the slots and the signal is directed to a controller. The controller compares the determined width of the slots with a pre-determined value and identifies slots having widths greater than the pre-determined value. The exterior surface of the pipe adjacent to the slots having determined widths greater than the pre-determined value is treated through causing one or more compression tools to be moved to selectively contact the exterior surface of the pipe adjacent to the identified slots so as to selectively reduce the width of the slots.

An electrical connection system includes an electrical connector electrically connected to a chip module, and an adapter disposed on one side of the electrical connector. The chip module laterally extends to form a conducting portion. Two rows of terminals are disposed in the adapter, and form a slot therebetween for the conducting portion to be inserted therein. When the conducting portion is not inserted in the slot, the width of the slot is greater than the thickness of the conducting portion, so that a zero insertion force is required for insertion of the chip module. After the chip module is inserted in the slot, under the effect of an external force, the width of the slot is reduced to an extent that the terminals urge against the conducting portion, which ensures close electrical connection between the terminals and the chip module.

The invention relates to a self-focusing laser processing device. A container for containing a non-linear medium is fixed between a lens and a workbench by the aid of a clamping mechanism. A laser beam is focused on the surface of the non-linear medium, the laser beam focused by the lens enters the non-linear medium to be transferred to produce self-focusing, and through two times of focusing by the lens and the non-linear medium, the laser beam leaving the container has the extremely small diameter and is linearly spread to the surface of a workpiece. The depth of the non-linear medium in the container, that is, the self-focusing distance L is related to energy of the laser beam and the refractive index of the adopted non-linear medium. A water jet auxiliary device is also provided, and the laser focus point on the surface of the workpiece coincides with the jet injection point center. Impact of water jet on the surface of the workpiece carries away residues and heat removed by laser.
