Implantable defibrillators are implanted into the chests of patients prone to suffering ventricular fibrillation, a potentially fatal heart condition. A critical component in these devices is an aluminum electrolytic capacitors, which stores and delivers one or more life-saving bursts of electric charge to a fibrillating heart. To reduce the size of these devices, capacitor manufacturers have developed special aluminum foils, for example core-etched and tunnel-etched aluminum foils. Unfortunately, core-etched foils don't work well in multiple-anode capacitors, and tunnel-etched foils are quite brittle and tend to break when making some common types of capacitors. Accordingly, the inventors devised a new foil structure having one or more perforations and one or more cavities with a depth less than the foil thickness. In an exemplary embodiment, each perforation and cavity has a cross-sectional area, with the perforations having a larger, for example, 2 to 100 times larger, average cross-sectional area than the cavities. Other embodiments of the invention include foil assemblies, capacitors, and implantable defibrillators that benefit from properties of the new foil structure.

The method in claim 8, wherein the state is a superconductivity state. 10. The method in claim 8, further comprising lowering the inductance, by changing the state to a superconductive state and raising the inductance by changing the state to a non-superconductive state. 11. The method in claim 10, wherein the change is accomplished by varying a temperature associated with the superconductive regions. 12. The method in claim 10, wherein the change is accomplished by varying a magnetic field associated with the superconductive regions. 13. The method in claim 10, wherein the change is accomplished by varying an electrical current associated with the microstrip line. ositioned at opposite sides of a portion of the synthetic resin whose width is smaller than the maximum width and having substantially a same height as said synthetic resin sheet and second lugs positioned at a downstream side in the direction of sheet conveyance and having a greater height than the surface of said synthetic resin sheet, and at least one of said first lugs and second lugs is covered with a high friction member having a greater coefficient of friction than the surface of said holding member or is implemented by said high friction member. 21. An apparatus for forming an image on a synthetic resin sheet, comprising: conveying means including a holding member for conveying the synthetic resin sheet while holding said synthetic resin sheet; transferring means for transferring a toner image formed on an image carrier, which has an endless, movable surface, to a surface of the synthetic resin sheet being conveyed by said conveying means by exerting a pressure; fixing means including a fixing member, which has an endless, movable surface, for fixing the toner image on the synthetic resin sheet being conveyed by said conveying means by exerting a pressure; and biasing means for biasing said holding member toward at least one of said image carrier and said fixing member; wherein at a downstream side in the direction of sheet conveyance a surface of said holding member is formed with lugs each including an upward slant, which rises from the downstream side toward an upstream side and is higher in level than said surface, said slant
