Abstract
Abstract An electronic circuitry comprising MOS integrated circuits is hermetically encased in a container and it is connected with external electrodes through an electrode lead-out terminal, after which an inert gas is introduced into the hermetically sealed container. This construction enables the electronic circuitry to operate with a high degree of reliability against sudden changes in the ambient conditions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
An electronic circuitry containment device comprising: an electronic circuitry including high impedance integrated circuits; a container having an open side; a closing lid fitted to the open side of said container to cooperate therewith to define therewith a hermetrically closed space encased by walls; said electronic circuitry being disposed in said space and having terminals; a hole provided in at least one of walls encasing said space; a flexible safety valve member normally closing and resiliently sealing said hole; a member on at least one of said walls, through which said terminals of said electronic circuitry extends outwardly from said closed space; said closed space being filled with an inert gas.
Claim 2
Dependent Claim
111 words
An electronic circuitry containment device comprising: an electronic circuitry including high impedance integrated circuits; a container having an open side; a closing lid fitted to the open side of said container to cooperate therewith to define therewith a hermetrically closed space encased by walls; said electronic circuitry being disposed in said space and having terminals; a hole provided in at least one of walls encasing said space; a flexible safety valve member normally closing and resiliently sealing said hole; a member on at least one of said walls, through which said terminals of said electronic circuitry extends outwardly from said closed space; said closed space being filled with an inert gas.
Claim 3
Dependent Claim
43 words
A device according to claim 1, wherein said safety valve member comprises a rubber plug which is inserted into said hole; said safety valve being operative to release the inert gas when an abnormally high pressure is built up in the closed space.
Claim 4
Dependent Claim
23 words
A device according to claim 1, wherein said member through which said terminals of said electronic circuitry extends, comprises a hermetic sealing element.
Claim 5
Dependent Claim
14 words
A device according to claim 1, wherein said integrated circuits comprise MOS integrated circuits.
Claim 6
Dependent Claim
17 words
A device according to claim 1, wherein said electronic circuitry comprises an assembly of various control circuits.
Claim 7
Dependent Claim
127 words
An electronic circuitry containment device comprising: a container having an open side; a closing lid fitted to the open side of the container to cooperate therewith to define a hermetrically closed space; an electronic circuitry disposed in said closed space and having high impedance integrated circuits and terminals; a hole provided in at least one of walls encasing said space; a flexible safety valve member hermetrically closing and resiliently sealing said hole; a member on at least one of said walls, through which said terminals of said electronic circuitry extends outwardly from said closed space; said closed space being filled with an inert gas; said safety valve member being operative to release the inert gas when an abnormally high pressure is built up in the sAid space.
