DEFINITION

Classification: 315/5.22

(under subclass 5.21) Subject matter, wherein the hollow device has a flexible wall to adjust the shape or a dimension of the device, usually for varying the width of the gap in the device across which the cathode-ray travels.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.48, for plural hollow distributed parameter devices having a ray passing through or in, at least one of the devices having a flexible wall for tuning purposes.

5.54, for a single plural hollow distributed parameter device having a ray passing through or in, and having a flexible wall for tuning purposes.
