Abstract: A novel raised polycide fusible link structure is described. This structure enables a highly reliable laser-cutting process to be used in which the fuse can be easily and totally severed over a wide range of laser energy levels. The primary feature of the structure is that the fusible link is located on a pedestal that raises it above the surface of the main body of the integrated circuit, thereby providing a measure of thermal isolation for the fuse when it is irradiated by the laser. An efficient process for manufacturing the structure is also described.

Abstract: A screw-joint type pneumatic tool connector, which comprises an air inlet coupling having received therein a conical spring and a valve, a lock nut connected to the front end of said air inlet coupling by means of screw joint, a stepped control bush having a C-shaped retainer ring externally mounted thereon and being connected to the rear end of the air inlet coupling with a seal ring set therebetween, a socket sleeved on the control bush with an air outlet coupling secured thereto at its rear end by means of screw joint. By means of moving the air outlet coupling inward inside the socket, the valve is moved away from the seal ring to form an air passage for the passing therethrough of compressed air to drive a tool to operate.
