摘要： Magnetic nanocomposite materials including iron, rare earth elements, boron, refractory metal and, optionally, cobalt are disclosed. Neodymium and lanthanum are preferred rare earth elements. The amounts of Nd, La, B and refractory metal are controlled in order to produce both hard and soft magnetic phases, as well as a refractory metal boride precipitated phase. The refractory metal boride precipitates serve as grain refiners and substantially improve the magnetic properties of the nanocomposite materials. The materials are particularly suitable for making bonded magnets.

摘要： A ratchet buckle has a body and a trigger. One end of the body has two opposite pivotal holes, two opposite positioning notches, and a pivotal shaft penetrating the pivotal holes. Two ends of the pivotal shaft each have a ratchet wheel synchronously rotating with the pivotal shaft. One end of the trigger has two opposite shaft holes engaged to the pivotal shaft of the body and has a positioning rod transversally mounted on the trigger to engage the two positioning notches of the body. By operating the trigger to set the pivotal shaft free, the pivotal shaft is easily rotated to reel a strap.

摘要： A patterned silicon nitride layer formed over a semiconductor integrated circuit wafer having a layer of pad oxide is often used as a mask for subsequent processing steps. Etching of the silicon nitride layer is difficult to control and can create defects in the pad oxide layer which are difficult to detect before the manufacture of the semiconductor integrated circuit wafer is completed. A method is described using potassium hydroxide treatment and scanning electron microscope evaluation of a test wafer for detection of defects at the silicon nitride etching step. Continued processing of defective wafers can be terminated and the silicon nitride etching step can be controlled using this method.
