A photovoltaic strip assembly is disclosed comprising a polyimide substrate, a thin film voltaic strip, and a transversely grooved, protection covering of a chlorofloural polymer. The grooves are provided to increase the flexibility of the strip, and may be V-shaped, flat bottomed with splayed sides
A photovoltaic strip assembly is disclosed comprising a polyimide substrate, a thin film voltaic strip, and a transversely grooved, protection covering of a chlorofloural polymer. The grooves are provided to increase the flexibility of the strip, and may be V-shaped, flat bottomed with splayed sides, or rounded to provide dome shapes between them. Similar grooves may be provided in the exposed surface of the substrate to further increase the flexibility of the strip. The grooves of the substrate may be aligned with ridges between the grooves of the protective covering, to receive these ridges when the strip is wound around a rechargeable battery or energy cell. In a different embodiment the grooves are between rows of hump-shaped protuberances. The protuberances of adjacent rows may be staggered.

The keyboard musical instrument as set forth in claim 11, in which said plural plates are concentrically curved so as to form said vertical portion and said connecting portion. 13. The keyboard musical instrument as set forth in claim 11, in which said plural plates are assembled into said pair of laminations by means of adhesive compound. 14. The keyboard musical instrument s set forth in claim 11, in which said plural plates are concentrically curved so as to form half of said vertical portion and half of said connecting portion in said pair of laminations, respectively, and said coupling means fixes said connecting portion to said case. 15. The keyboard musical instrument as set forth in claim 11, in which said pair of laminations provide halves of said vertical portion held in face-to-face contact with each other and halves of said connecting portion merged into said halves of said vertical portion and spaced from each other, wherein said leg further comprises a reinforcing block placed into a space between said halves of said connecting portion and fixed to said laminations for enhancing a mechanical strength of said core. 16. The keyboard musical instrument as set forth in claim 11, in which at least one reinforcing sheet is inserted into said plural plates for enhancing a mechanical strength of said core. 17. The keyboard musical instrument as set forth in claim 16, in which said at least one reinforcing sheet is formed of a material selected from the group consisting of a metallic fiber fabric, a synthetic resin fiber fabric and a carbon fiber fabric. 18. The keyboard musical instrument as set forth in claim 11, further comprising plural decorative panels fixed to certain surfaces of said core where boundaries between said plural plates are exposed. 19. The keyboard musical instrument as set forth in claim 18, further comprising a caster connected to said core for permitting said keyboard musical instrument to slide. 20. The keyboard musical instrument as set forth in claim 11, in which each of said plural plates is formed by a sheet of veneer.
