Title: Formation of insulating film
Inventor: NAKANISHI SHIRO
IPC: H01L21/316
Filed: 1986-03-10
Abstract: PURPOSE:To obtain a semiconductor device with excellent characteristics in which high dielectric strength insulating films are formed by a method wherein an SiO2 film, an MgO film and MgO.Al2O3 film are successively formed and made to grow by epitaxial growth on a substrate through specific processes. CONSTITUTION:A process for forming a thin SiO2 film 31 on a substrate 3, a process inducing reaction between the SiO2 film 31 and magnesium compound and make a magnesia (MgO) film 32 grow by epitaxial growth, a process for oxidizing the substrate 3 through the MgO film 32 to form an SiO2 film 33 at the boundary between the substrate 3 and the MgO film 32 and a process making a single crystal MgO.Al2O3 film 34 grow by epitaxial growth constitute the whole insulating film forming process. The reason why the SiO2 film 33 is formed by the oxidization after the MgO film 32 is made to grow is that, if the thick SiO2 film were formed beforehand, the single crystal MgO film 32 could not be formed and, as a result, the single crystal MgO.Al2O3 film 34 could not be obtained. With this constitution, a semiconductor device with excellent characteristics can be obtained and high dielectric strength insulating films can be formed.

Filed: 1993-03-12
Abstract: PURPOSE:To improve the accuracy of position measurement by selecting the combination of satellites having the smallest value of accuracy deteriorating coefficient with respect to each axial direction of a coordinate system. CONSTITUTION:The radio wave, which is received with an antenna part 10, is converted into the electric signal in a high-frequency processing part 20 and a demodulating part 30 and further converted in an A/D converter part 40. An operating part 60 computes the accuracy deteriorating coefficient and the coordinates of position measurement by using the program, which is read out of a memory device 50, based on the signal from the converter part 40. The result is outputted into a display part 70. The combination of four satellites is sequentially selected among the observed satellites. Each accuracy deterioration coefficient is computed for the axes of X, Y and Z. Whether each computed accuracy deterioration coefficient is the best (smallest) value or not among the other combinations of four satellites, which have been computed beforehand in the observed satelliete, is judged. When the value is best, the best value of each accuracy deterioration coefficient and the combination of the satellites are rewritten and recorded. The process is repeated until the a combination of all observed satellites is finished. Thus, the best combination is selected.

Title: Retaining wall
Inventor: TERADA TOMOTERU
IPC: E03F5/04
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent inclination by soil pressure by fixing a concrete plate-made counterfort at a position downward of the U-shaped groove of a retaining wall one side so as to be at a substantially right angle to a retaining wall and substantially parallel with the expansion length direction of the U-shaped groove and protruding the edge from the part of the U-shaped groove. SOLUTION: A concrete plate-made counterfort 3 is fixed so as to be at a substantially right angle to a retaining wall 1a and substantially parallel with the expansion length direction of a U-shaped groove 2. Thereby since the load of back-filling soil is applied on the counterfort 3 during execution, soil pressure applied on the counterfort 3 is enlarged. The edge of the counterfort 3 is protruded from the part of the U-shaped groove 2. Thereby since the part of a road whose edge part is positioned is a part treaded on by passage of an automobile or the like, large soil pressure is applied on the edge of the counterfort 3. The soil pressure applied on the counterfort 3 is further enlarged, and the retaining wall 1a is difficult to incline. Thus, inclination by soil pressure can be prevented.
