Title: Manufacture of semiconductor device
Inventor: YAMAUCHI TSUNENORI
IPC: H01L21/76
Filed: 1988-06-22
Abstract: PURPOSE:To secure the film thickness of a non-oxidizing insulating film of the corner part of a U-shaped groove so that it may have the satisfactory thickness and prevent the development of a crystal defect due to the stress of thermal oxidation in a semiconductor substrate by directly nitrifying polycrystal silicon after making its silicon grow in the U-shaped groove. CONSTITUTION:A U-shaped groove 12 is formed in a semiconductor substrate 11 and an oxide film 13 is provided at the inside of the U-shaped groove 12 and then, this device makes polycrystal silicon 14 grow on the surface of the oxide film 13. Polycrystal silicon 14 turns into a nitriding film 15 as a non-oxidizing insulating film by directly nitrifying its silicon 14 and polycrystalline silicon 17 is buried inside the U-shaped groove 12 and an oxide film 18 is formed by oxidizing the surface of polycrystalline silicon 17. Polycrystalline silicon 17 has a property that it can grow to a sufficient thickness even an a corner part 16 of the U-shaped groove and further, it may turn into the nitriding film 15 easily by heating it in an atmosphere of ammonium. As the nitrided film 15 is formed as the non-oxidizing insulating film having the sufficient thickness even in the corner part 16 of the U-shaped groove, this device prevents the development of a crystal defect due to the stress in the process of thermal oxidation on the semiconductor substrate.

Title: Azimuth measuring instrument
Inventor: KAJIOKA HIROSHI
IPC: G01C17/00
Filed: 1995-06-21
Abstract: PURPOSE: To measure azimuth in real time by calibrating the azimuth of OFG-Y with the azimuth measured by OFG-C only when the amount of change of azimuth measured by an optical fiber gyro for compass (OFG-C) and an optical fiber gyro for yaw rate (OFG-Y) matches with a specific accuracy. CONSTITUTION: A sending coil 3 for OFG-Y and a turntable 4 are provided on a level device 2 for maintaining a horizontal surface 1, a sensing coil 5 for OFG-C is erected vertically on the turntable 4, and a signal processor 6 is provided on the side surface. The OFG-C measures an absolute azimuth which becomes a calibration standard from the angular velocity due to the rotation of earth which is detected by the coil 5 and the OFG-Y measures a relative azimuth change from the angular velocity in yaw angle direction which is detected by the coil. Then, it is judged that no oscillation results when the changes in azimuth measured by the OFG-C and OFG-Y match with a specific accuracy, thus calibrating the OFG-Y azimuth and hence measuring azimuth accurately in real time.

IPC: G01R33/54
Filed: 1995-06-21
Abstract: PURPOSE: To restrain generation of an artifact by performing Fourier transform and absolute value operation with respective divided areas on sampling data with respective divided areas when scanning is performed by dividing a spatial frequency area. CONSTITUTION: When echo data of areas Sr to Sg on (k) spaces is obtained by divided scanning, data of the respective areas are juxtaposed on the respective (k) spaces, and the other areas are set in 0, and Fourier transform is performed with respective areas, and complex imacje data Va to Vs composed of a real number part R and an imaginary number part I are obtained. Operation is performed on this absolute value, and afterwards, absolute value image data of the respective areas are added together, and a magnetic resonance image is formed. Since generation of an artifact in an adjacent part of the areas can be prevented by carrying out in this way, even if phases of sampled data collected in the respective areas are different from each other, generation of the artifact such as ringing can be prevented.
