摘要： An apparatus for continuously manufacturing a corrugated sheet having a varying fold width and also having fold lines extending either straight or in wavy or zig-zag fashion in a direction widthwise thereof. The apparatus includes upper and lower toothed rolls each made up of a group of toothed discs and having a circumferential groove defined between each neighboring toothed discs. At least one of the upper and lower toothed rolls is supported for adjustment in position relative to and in a direction towards and away from the other of the upper and lower toothed rolls. Upper and lower guide bars while extending in a direction parallel to the upper and lower toothed rolls are accommodated within the circumferential grooves for movement in a direction towards and away from each other over a distance corresponding to the height of each tooth of any one of the upper and lower toothed rolls. During a continuous passage of the web of sheet through a biting region defined between the upper and lower toothed rolls, the web of sheet is alternately folded by the interaction between the upper and lower toothed rolls to provide the corrugated sheet.

摘要： A filter is provided which maintains a low insertion loss characteristic of a filter contained in a casing with a very simple construction that the internal wall of the casing is formed by a superconductor. A coplanar waveguide filter 22 comprises a dielectric substrate 1, a plurality of resonators 5a, 5b, 5c and 5d and input/output terminal sections 4a and 4b, each of which is formed by a center conductor 2 and ground conductors 3a and 3b, both formed on the same surface of the dielectric substrate 1, with the ground conductors 3a to 3d being formed on the opposite sides of and in parallel relationship with the center conductor 2. The filter 22 is contained within a casing 21 having an internal wall, the surface of which is formed with a layer of superconductor 23. By way of example, a high temperature superconductor such as lanthanum-, yttrium-, bismuth- or thallium-superconductor is deposited as a film on a substrate of a metal oxide material such as MgO, SrTiO3, LaGaO3, LaAlO3 to provide a superconductor filmed substrate 25, which is applied to the internal surface of the casing 21. Electromagnetic power which is irradiated from the filter 22 does not produce a power loss when it impinges on the layer of superconductor 23 in its superconducting state, but is reflected therefrom to be absorbed by the filter 22, thus reducing the filter insertion loss.
