Abstract: A lancet device used as a puncturing tool for creating a hole in a person's skin to obtain blood for testing. The device comprises a hammer which propels needle points into skin to release a droplet of blood. The device comprises a method for adjusting the needle's penetration. The device comprises a renewable wheel to carry the needles, and it is exchanged for a new needle wheel when no unused needles remain. The device comprises a method for rotating the needle wheel. The device shields the needle points from human touch. The device comprises a numbering system to indicate the needles remaining unused. The device is designed to minimize pain and bruising. Its simplicity means even children, the aged, and the handicapped can safely and economically use this device.

Abstract: Amorphous and polycrystalline III-V semiconductor including (Ga,As), (Al,As), (In,As), (Ga,N), and (Ga,P) materials were grown at low temperatures on semiconductor substrates. After growth, different substrates containing the low temperature grown material were pressed together in a pressure jig before being annealed. The annealing temperatures ranged from about 300° C. to 800° C. for annealing times between 30 minutes and 10 hours, depending on the bonding materials. The structures remained pressed together throughout the course of the annealing. Strong bonds were obtained for bonding layers between different substrates that were as thin as 3 nm and as thick as 600 nm. The bonds were ohmic with a relatively small resistance, optically transparent, and independent of the orientation of the underlying structures.

Abstract: The present invention is a Hackle Grabber which is a fly tying tool used to assist in the clasping and wrapping of materials, such as hackle feathers, peacock herl, tinsel strips, lead wire, and other materials, on the shanks of hooks used for constructing fishing flies. The design of the tool will allow the materials to be wrapped about the shanks of hooks without imparting a twist in the materials each time a wrap is made. The tool is comprised generally of a set of tubes, a spring restrained projectable metal ball, and a rotating handle, all combined so that the metal ball can be made to clasp feathers or small strings of material against one end of a tube, and the tool can itself rotate and wrap the material around a shank without imparting a twist in the material.
