[Optimal shape of the nerve ending of the tissue encapsulated mechanoreceptor (Pacinian corpuscle)].

<p>A new method for cutting optical fibers is presented. A smooth scratch, without anyvisible cracks and chipping, is circumferentially made around the complete periphery beforethe fiber is fractured by simple axial tension. Break angles of 0.50 are easily obtained. Coated-glass fibers and plastic-clad fibers arecut properly for the first time owing to the novel scratching procedure. A compact tool is used to perform the required sequence of operations automatically.</p>
