An enhanced door lock is capable of being locked from an inner side of a doorplate. At the outer lock portion, a ring seat and a C ring clamp two sides of the outer plate of the doorplate so as to enhance the structure of the doorplate to prevent the door lock from being pulled out. The inner cover is installed with a positioning hole. One side of a top of the control knob is drilled with a stud receiving groove. A positioning pin is placed in a stud receiving groove. The outer sleeve and the stud of the positioning pin are coupled with the stud receiving groove; then the bead resisting against the spring exactly pushes the positioning groove of the stud to resist against a positioning groove. By this structure, the lock is locked from the inner side of the doorplate.

An oscillator package includes a header substrate with a number of through holes formed therein, a copper post passed through each through hole, a ceramic substrate securely mounted to and supported by the copper posts for mounting a die and a crystal thereon, a substantially L-shaped lead securely attached to an underside as well as a lateral side of the header substrate and contacting each copper post, and a ceramic cover housing the die and crystal. A metal film is applied to an inner periphery of the hole, and the copper posts are mounted in the holes after the metal-film is sintered. An outer periphery of the copper post is plated by nickel then gold. The lead is mountable to a circuit board by soldering, and the solder covers an overall area of the lead. The ceramic cover has at least a 90% weight of aluminum oxide.
