Claims27
An envelope comprising a face plate, a rear plate arranged so as to be opposite to said face plate, an outer frame arranged between said face and rear plates and surrounding a circumference, a face plate joining portion for joining said outer frame and said face plate, and a rear plate joining portion for joining said outer frame and said rear plate to each other, with one or both of said face plate joining portion and said rear plate joining portion including a sealant having a seal function and an adhesive having an adhesive function.
An image-forming apparatus, comprising:
- an envelope comprising a face plate, a rear plate arranged so as to be opposite to said face plate, an outer frame arranged between said face and rear plates and surrounding a circumference, a face plate joining portion for joining said outer frame and said face plate, and a rear plate joining portion for joining said outer frame and said rear plate to each other, with one or both of said face plate joining portion and said rear plate joining portion including a sealant having a seal function and an adhesive having an adhesive function;
- an image-forming member and an electron accelerating electrode formed in said face plate;
- and
- an electron source formed in said rear plate.
An envelope constructed by combining plural members and airtightly maintaining an internal space with respect to the exterior, characterized in that the envelope has a joining portion airtightly joining said members to each other by a sealant having a seal function, and said airtight joining is reinforced by an adhesive having an adhesive function.
An image-forming apparatus, comprising:
- an envelope constructed by combining plural members and airtightly maintaining an internal space with respect to the exterior, characterized in that the envelope has a joining portion airtightly joining said members to each other by a sealant having a seal function, and said airtight joining is reinforced by an adhesive having an adhesive function;
- and
- an image-forming member arranged within the envelope.
A manufacturing method of an envelope constructed by combining plural members and airtightly maintaining an internal space with respect to the exterior, said method characterized by comprising a first process for airtightly joining said members to each other by a sealant having a seal function and a second process for reinforcing said airtight joining by an adhesive having an adhesive function.
An image-forming apparatus comprising:
- a face plate;
- a rear plate arranged so as to be opposite to said face plate;
- an outer frame arranged between said face and rear plates and surrounding a circumstance;
- a face plate joining portion for joining said outer frame and said face plate;
- a rear plate joining portion for joining said outer frame and said rear plate to each other, with one or both of said face plate joining portion and said rear plate joining portion including a sealant having a seal function and an adhesive having an adhesive function;
- and
- a member for emitting light by electroluminescence arranged in an envelope formed within said face plate, said rear plate and said outer frame.
An envelope comprising:
- plural members combined and airtightly maintaining an envelope having an internal space with respect to an exterior;
- and
- a sealant having a metal or an alloy, wherein the internal space between said members is airtightly sealed by said sealant;
- and
- a reinforcing portion reinforcing said envelope outside of the internal space sealed by said sealant.
An image-forming apparatus comprising:
- an envelope constructed by combining plural members and airtightly maintaining an internal space with respect to an exterior, and including a sealant having a metal or an alloy, with the internal space between said members being airtightly sealed by said sealant;
- a reinforcing portion reinforcing said envelope outside of the internal space sealed by said sealant;
- and
- an image-forming member arranged within said envelope.
