Abstract
Abstract A method of forming a hermetic seal with high hermeticity includes the steps of subjecting metal components or stock to hot isostatic pressing, forming a pin or body from the stock, and bonding the pin to a surface defining an opening in a hermetic body. A terminal with high hermeticity is provided by a metal component subjected to hot isostatic pressing and a seal bonded to the pin and body. The seal can be a glass to metal seal or ceramic to metal.

Claim 2
Independent Claim
47 words
The method of forming a hermetic seal with high hermeticity by subjecting components and/or raw stock and/or ingot to hot isostatic pressing, forming a body and/or pin from said stock, assembling said seal from said components and bonding said hermetic seal into an opening in a body.
Claim 3
Dependent Claim
23 words
A terminal with high hermeticity comprising one or more metal components subjected to hot isostatic pressing and a seal bonded to said components.
Claim 4
Dependent Claim
23 words
A terminal with high hermeticity comprising one or more metal components subjected to hot isostatic pressing and a seal bonded to said components.
Claim 5
Dependent Claim
12 words

Claim 6
Dependent Claim
14 words
The terminal of claim 2 wherein the seal is a ceramic to metal seal.
Claim 7
Independent Claim
62 words
The method of forming a hermetic terminal of the type having a body and at least one pin passing through and sealed to said body, to form a seal with high hermeticity comprising subjecting metal pin stock to hot isostatic pressing, forming a pin from said pin stock, and thereafter bonding said pin to a surface defining an opening in said body.
Claim 8
Independent Claim
62 words
The method of forming a hermetic terminal of the type having a body and at least one pin passing through and sealed to said body, to form a seal with high hermeticity comprising subjecting metal pin stock to hot isostatic pressing, forming a pin from said pin stock, and thereafter bonding said pin to a surface defining an opening in said body.
Claim 9
Dependent Claim
21 words
