DEFINITION

Classification: 315/5.54

(under subclass 5.53) 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:

5.22+, for a hollow distributed parameter device having a ray passing through or in, which ray returns to the device, the device having a flexible wall to adjust the tuning.

5.48, for a plurality of tunable hollow distributed parameter devices and a single ray passing through each, and at least one of the devices having a flexible wall for tuning.
