Title: Head slider and magnetic disk device
Inventor: YOTSUYA MICHIO
IPC: G11B5/60
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To suppress the fluctuation of static floating amt. over the whole surface of a magnetic disk and also to reduce a static roll by generating a negative pressure enough to offset the increase of positive pressure due to the increase of linear velocity. SOLUTION: In this head slider 16, a positive pressure generating part 161 is formed on its surface opposite to the magnetic disk, and in the generating part 161, a 1st negative pressure generating part 163 and a 2nd negative pressure generating part 164 are formed to narrow the area of the generating part 161 from the vicinity of the middle of the generating part 163 toward an air outflow end of the generating part 163. When the slider 16 approaches the rotating magnetic disk, the positive pressure is generated on the generating part 161, and the negative pressure the generating parts 163 and 164 respectively. The slider 16 is given floating force by a difference between these positive and negative pressures.  Then, even when the linear velocity of the slider 16 is changed by varying the position of the slider 16 in the radial direction of the magnetic disk, the positive pressure and the negative pressure are both varied in the same direction in response to a variation in this linear velocity, so that the rise of the floating force due to the increase of the linear velocity is suppressed.

Title: Manufacture of semiconductor device
Inventor: YAMAMOTO NORITOSHI
IPC: H01L21/306
Filed: 1992-02-12
Abstract: PURPOSE:To relieve electric field concentration to a curved part, by a method wherein, after an aperture for diffusing impurities opposite to a semiconductor substrate is formed, anisotropic etching is performed, and then the impurities are diffused and introduced. CONSTITUTION:By photolithography and photoetching, an oxide film 2 is eliminated, and resist 5 is eliminated. By using etching solution whose etching rate is different with regard to the face orientation, the surface of silicon 1 is etched. Since the etching rate of (111) orientation is different from that of (100) orientation, constant angles are formed at edge parts. After that, by a thermal diffusion method, second conductivity type impurities are introduced, a P-type impurity diffusion layer 7 is arranged, and a PN junction is formed. Since an angle slope of anisotropic etching is formed at the edge part of the PN junction, the edge is smoothed, and electric field concentration at this part is relieved. Thereby the withstand voltage can be improved.
