摘要： A Periodic Table Group 13 metal nitride crystal is grown by causing a reaction of a Periodic Table Group 13 metal phase with a nitride-containing molten salt phase to proceed while removing a by-product containing a metal element except for Periodic Table Group 13 metals, from the reaction field. According to this process, a high-quality Periodic Table Group 13 metal nitride bulk crystal can be produced under low pressure or atmospheric pressure.

摘要： A texturing apparatus for applying a texturing to a magnetic recording medium, such as a magnetic disk including a hard drive. A substrate such as a magnetic disk is held by a substrate rotating system, which is capable of rotating the substrate. A movable laser beam source including an electro-optic modulation circuit directs a laser beam through a focusing element onto the surface of the substrate. The modulation circuit allows the laser beam to pulse at a frequency from 0.1 to 100 MHz. The focusing element allows a laser beam spot diameter of 0.2 to 4 .mu.m on the surface of the substrate. This texturing includes texturing the magnetic head contact start and stop (CSS) area of hard disks.

摘要： In an aluminum electrolytic cell in which alumina is electrolyzed by electric current flowing between an anode electrode and a cathode electrode, ferromagnetic rods are disposed on the anode electrode in parallel with a shorter end wall of the cell. The ferromagnetic rod is magnetized by a horizontal component of a magnetic field created in the cell by the current to produce a magnetic field containing a vertical component that decreases a gradient of a vertical component of the magnetic field created by the current. The magnetic member may be disposed above or below an aluminum metal layer or above the anode electrode. In the last mentioned case, a ferromagnetic bar may be wound about an anode supporting rod to form a coil having opposite terminals extending in the horizontal direction.

摘要： A magnetron sputtering apparatus has a target disposed above an inner magnetic pole surrounded by an outer magnetic pole of opposite polarity and a gradient adjusting means mounted underneath the target and interposed between the inner and outer magnetic poles. The gradient adjusting means operates such that the gradient of the component of the leakage magnetic field vertical to the target is reduced over the middle portion of the target, between the inner and outer magnetic poles, and is increased at portions closer to the magnetic poles. The gradient adjusting means may be made of a soft magnetic material or a permanent magnet material, and the soft magnetic material may be used alone or in combination with the permanent magnet material. A second permanent magnet may be used in conjunction with the use of a permanent magnet as the gradient adjusting means. The magnetron sputtering apparatus prevents localized erosion of the target, thus making the area of erosion on the target more uniform, prolonging the life of the target, and providing for more even sputtered films.
摘要翻译：磁控管溅射装置具有设置在由相反极性的外磁极围绕的内磁极上方的靶和安装在靶下方并插入在内磁极与外磁极之间的梯度调节装置。梯度调整装置的操作使得垂直于目标的泄漏磁场的分量的梯度在目标的中间部分之间在内部和外部磁极之间减小，并且在更靠近磁极的部分处增加。梯度调节装置可以由软磁材料或永磁材料制成，并且软磁材料可以单独使用或与永久磁铁材料组合使用。结合使用永磁体作为梯度调节装置，可以使用第二永久磁铁。磁控溅射装置防止靶材的局部侵蚀，从而使目标上的侵蚀面积更均匀，延长靶材的寿命，并提供更均匀的溅射膜。
