Abstract
An electron tube includes at least one metal film formed on a base, at least one linear member provided above the base, and at least one additional member for connecting said at least one linear member to said at least one metal film. The at least one linear member is connected to the at least one metal film by welding the at least one additional member to the at least one metal film.
Claims19
An electron tube comprising:
- at least one metal film formed on a base;
- at least one linear member provided above the base, wherein at least a part of said at least one linear member is a tension force applying portion for exerting a tension force;
- at least one spacer for defining a distance between said at least one linear member and the base;
- and
- at least one additional member for connecting one end of said at least one linear member to said at least one metal film,
- wherein said at least one additional member is welded to a portion of said at least one metal film, said one end of said at least one linear member being disposed between said at least one additional member and said at least one metal film, and the entire portion of said at least one metal film being in direct contact with the base.

An electron tube comprising:
- at least one metal film formed on a base;
- at least one linear member provided above the base and divided into a body portion and a fixture portion for fixedly attaching the body portion to said at least one metal film, wherein at least a part of said at least one linear member is a tension force applying portion for exerting a tension force;
- at least one spacer for defining a distance between said at least one linear member and the base;
- and
- at least one additional member, for fixedly connecting the fixture portion to said at least one metal film,
- wherein said at least one additional member is welded to said at least one metal film, the distance between the fixture portion of said at least one linear member and the base or the distance between said at least one additional member and the base being not greater than the thickness of said at least one metal film.

- at least one spacer for defining a distance between said at least one linear member and the base;
- and
- at least one additional member for connecting one end of said at least one linear member to said at least one metal film,
- wherein said at least one metal film includes a generally flat part, the entire flat part of said at least one metal film having two opposite surfaces, said at least one additional member being welded to one of the opposite surfaces wherein said one end of said at least one linear member is connected to said at least one metal film at the same position where said at least one additional member is welded to said one of the opposite surfaces, and the other opposite surface being substantially parallel with and in direct contact with the base.
