Title: Method and apparatus for production of magnetic recording medium substrate
Inventor: KANEKO HIDEO
IPC: B23K26/38
Filed: 1992-08-28
Abstract: PURPOSE:To produce the magnetic recording medium substrate, such as substrate for a magnetic disk, which maintains high flatness and concentricity with high efficiency without variations. CONSTITUTION:A wafer 2 is formed by slicing a single crystal silicon rod 1 of a large diameter (diameter d2) at a high speed of a slicing speed V2>V1. Plural sheets of doughnut-shaped disks 3 each having a central hole 4 and a small diameter (diameter d1) are cut out of this wafer and are finished, by which finished products are produced. The cutting out is executed by irradiating the central hole 4 of the cut out disk 3 and edge parts 27, 28 of the outer periphery thereof with a laser beam and rotating the wafer 2 around the central hole 4 at it center. The positioning of the cutting out position of the disk 3 to be cut out is executed by turning the wafer 2 to a prescribed indexing angle position. Where, V1 denotes the sliding speed necessary for generating the warpage of a prescribed value or below from the single crystal silicon rod of the diameter (diameter d1).

Abstract: PURPOSE:To largely delete the damage of intermediate insulating film due to stepwise difference of polysilicon periphery and disconnection of aluminum wirings by forming polysilicon, then implanting <31>P<+> in high density shallow in the surface to generate density difference between the surface and the interior of the polysilicon to cover it with positive resist, and dry etching it. CONSTITUTION:A polysilicon 3 is formed through a gate oxide film 2 on an Si substrate 1. Then, <31>P<+> is implanted in high density shallow in the surface of a polysilicon 3. Then, a photolithography is executed, a positive resist 6 is patterned, and dry etched. Thus, density difference occurs between the vicinity of the surface and the interior of the polysilicon 3, and a taper 7 is formed on the side of the polysilicon 3 due to the difference of the etching rate due to the density difference. Then, an intermediate insulating film 4 and aluminum 5 are formed. Even if the film 4 and the aluminum 5 are formed, the stepwise difference of certain degree due to the taper 7 can be alleviated.

Title: Video camera
Inventor: FUKUDA KYOKO
IPC: H04N19/51
Filed: 1992-08-31
Abstract: PURPOSE:To provide the video camera which is miniaturized and has the weight reduced and has less degradation of the picture quality and avoids erroneous detection of a motion vector and accurately performs the camera-shake. CONSTITUTION:A CCD image pickup element 3 in the PAL system is used to output a video signal to be outputted in the NTSC system. The motion in the vertical direction is detected by a vertical-direction angular speed sensor 5, and the read position of the CCD image pickup element 3 is controlled in accordance with this detection output to correct the camera-shake in the vertical direction. The motion vector is detected by a motion vector detecting circuit 11, and the read position of a line memory 13 is controlled in accordance with the motion vector to correct the camera-shake in the horizontal direction. When the motion vector is detected and the read position of a line memory 13 is shifted to correct the camera-shake in the horizontal direction, the motion vector in the vertical direction cannot exist because the camera-shake in the vertical direction is already corrected. Consequently, the motion vector in an area having a component in the vertical direction is made unreliable.
