Method of making a vapor device

Claim 1

METHOD OF OUTGASSING AND EVACUATING A VAPOR DEVICE HAVING AN ENVELOPE, SAID ENVELOPE INCLUDING A HEAT INPUT REGION AND A HEAT DISSIPATION REGION AND CONTAINING A VAPORIZABLE HEAT TRANSFER MEDIUM, SAID EVELOPE AT SAID HEAT DISSIPATION REGION INCLUDING WALLS DEFINING AN ORIFICE FOR VENTING GASES FROM SAID ENVELOPE, SAID METHOD COMPRISING: (A) EVACUATING SAID ENVELOPE, (B) HEATING SAID INPUT REGION TO A FIRST TEMPERATURE THAT IS AT LEAST AS HIGH AS THAT REQUIRED FOR VAPORIZING SAID HEAT TRANSFER MEDIUM, WHEREBY SAID HEAT TRANSFER MEDIUM URGES SAID GASES THROUGH SAID ORIFICE, (C) HEATING SAID HEAT DISSIPATION REGION TO A SECOND TEMPERATURE HIGHER THAN SAID FIRST TEMPERATURE BUT BELOW A THIRD TEMPERATURE AT WHICH A WALL OF SAID ORIFICE SOFTENS, WHEREBY THAT PORTION OF SAID HEAT TRANSFER MEDIUM PASSING THROUGH SAID ORIFICE IS PRESERVED IN THE VAPOR STATE FOR PREVENTING EXCESS LOSS OF SAID MEDIUM THROUGH SAID ORIFICE, AND (D) HEATING SAID HEAT DISSIPATION REGION TO SAID THIRD TEMPERATURE, WHEREBY SAID WALL OF SAID ORIFICE SOFTENS AND CLOSES SAID ORIFICE.
