A process of fabricating a molecular electronic device that preserves the integrity of the active molecular layer of the electronic device during processing is described. The device has two retractor blades facing each other and held in a common frame, the retractor blades are insertable into a surgical incision in a patient and moveable away from each other along a main axis so as to widen the surgical incision; and a connecting pin attached at a distal end of each retractor blade. The present invention is also directed to methods of forming a golf ball containing an IPN in one or more of the layers. Additional embodiments include improved heat dissipation within single transistors. The drive wheel assembly is to be in continuous contact with the inner surface of the ball. The movable rack is driven to perform advance-and-retreat motions between a clamping position where the movable rack fits together with the stationary rack and an unclamping position where the clamping state is released.
