Title: Compression jointing pipe for wire with projection
Inventor: TOMARI KATSUYA
IPC: H01R4/18
Filed: 1995-03-13
Abstract: PURPOSE: To make simple and good compression joint possible without using a special dice. CONSTITUTION: This compression jointing pipe has an inside 14d formed into a circle whose bore is approximately equal to the outside diameter of a protruded wire, and has an outside 14e formed into an ellipse. The cross section A of the wall thickness between the inside and the outside is approximately equal to the cross section of the wall thickness of the inside and outside of another compression jointing pipe used in compressing a wire from which a protrusion has been removed. Therefore when the pipe is compressed using a standard compression dice in such a way that its thick wall part 14f is crushed first, the wall of the thick part 14f flows to a thin- wall part 14g, and the pipe is compressed into a hexagonal shape as a whole.  In this case, in the compression jointing pipe for protruded wire, the cross section A of the wall thickness between the inside and the outside is about equal to the cross section of the wall thickness between the inside and the outside of the latter compression jointing pipe used in compressing wire from which a protrusion has been removed, so even when the pipe is compressed with a standard compression dice, no burr forms at the junction of upper and lower dices, and the compressive force does not become insufficient.

Thereafter, O2 gas is exhausted to the outside of a system without taking out a sample into atmosphere. Then, a single crystal silicon film 7 is grown. The formation of a high resistance layer at the surface of the layer 6 can be prevented by the fact that the layer 6 is the single crystal and by the single crystal silicon cap of the layer 7. Therefore, the resistance of an emitter can be made sufficiently small.
