A compact, lightweight, laser target designator uses a TIR bounce geometry to place an end-pumped gain element functionally in the center of the resonator path, thereby allowing the resonator path to be terminated by a pair of crossed Porro prisms, so that the designator produces a high quality beam that is insensitive to alignment and temperature, and is low in manufacturing cost. The rotary cutting tool also includes a plurality of light emitting diodes for illuminating a point of cut of the rotary cutting tool. The invention also encompasses novel mahogany gene products, including mahogany proteins, polypeptides and peptides containing amino acid sequences mahogany proteins, fusion proteins of mahogany proteins polypeptides and peptides, and antibodies directed against such mahogany gene products. The telemetry module obtains power from the telemetry signal during transcutaneous telemetry communication. The first silicon nitride film and the second silicon nitride film form a contact hole therein by etching both of the first silicon nitride film and the second silicon nitride film collectively by dry etching. The unit cell is placed in the recessed section, the recessed section is covered with a portion of the jacket, and the cathode and anode lead terminals are each connected to corresponding outer ends of the rolled electrodes, are placed on the side of the rolled electrodes that is exposed from an opening of the recessed section, and extend straight out of the jacket.
