Abstract: A connector for a coaxial cable includes a fastening sleeve received in a tubular end piece and the cable extends through the fastening sleeve. The fastening sleeve includes a tapered inner periphery. A threaded piece is threadedly connected to the end piece and includes a tapered inner periphery which presses a thinner portion at the tapered inner periphery of the fastening sleeve so as to apply an inward force to the fastening sleeve to secure the cable without using any special tool. A tube securely extends through the threaded piece and the core of the cable extends through the tube. A connection collar is rotatably mounted to the tube and has a connection threaded portion which is used to connect with a jack of an electric appliance.

Abstract: A method and system for predicting gate reliability. The method comprises the steps of stressing a gate dielectric test site to obtain gate dielectric test site data and using the test site data to predict gate reliability. Preferably, the test structure and the product structure are integrated in such a manner that a test site occupies some of the product area and the product itself occupies the remainder of the product area.
