The present invention provides transgenic plants which after harvest degrade the lignin and cellulose therein to fermentable sugars which can further be fermented to ethanol or other products. In particular, the transgenic plants comprise ligninase and cellulase genes from microbes operably linked to a DNA encoding a signal peptide which targets the fusion polypeptide produced therefrom to an organelle of the plant, in particular the chloroplasts. When the transgenic plants are harvested, the plants are ground to release the ligninase and cellulase which then degrade the lignin and cellulose of the transgenic plants to produce the fermentable sugars.

In a permanent magnet rotor, a power transmitting shaft is connected to an axial end of a solid cylindrical permanent magnet, and a reinforcement sleeve is fitted on the outer circumferential surface of the permanent magnet. Thus, the shaft is not required to be passed through the permanent magnet as was the case with the conventional permanent magnet rotor for the purpose of transmitting the rotational torque and increasing the overall rigidity, and the increase in the axial dimension of the rotor due to the reduction in the cross sectional area of the permanent magnet can be avoided. Also, because the sleeve surrounds the permanent magnet, the resistance to centrifugal stress resulting from a high speed rotation and repeated bending stress owing to vibrations can be improved.

A penile prosthesis beneficially includes components coated with parylene in order to increase product life and reduce wear. In particular, components of the inflatable cylinder benefits from having been coated with parylene. The parylene-coated cylinder components are resistant to wear generated by pinching of the cylinder when the cylinder is in a flaccid state. The parylene-coated cylinder may be formed by masking a tube of silicone (or other appropriate material) and vapor coating the silicone tube with parylene. Further, where a double walled cylinder is used, each of two tubes making up the double wall cylinder can have their surfaces coated with parylene, thus increasing cylinder life and avoiding wear.
