Title: Earth work
Inventor: OKUNO NOBORU
IPC: E02D17/18
Filed: 1979-06-27
Abstract: PURPOSE: To make a wider land in a short period of time as well as economically by a method wherein a pile is driven into the land to be developed or formed, thereafter a part of the pile is expanded to open to destroy the ground.  
     CONSTITUTION: An expanding member 3 is pivotaly arranged via a pin at the leading end of the pile main body 1. The pile A is driven into the land to be developed or formed, and then the top end of the expanding member 3 is expanded around the pin under an action of the hydraulic cylinder 5 installed between the expanding member 3 and the pile main body 1. As a result, the ground pushed by the expanding member 3 is destroyed and the land facing to a valley is buried. After the ground is destroyed, the pile A is pulled up, moved to another place and driven into the ground again and at the same time said operation is repeated to enable an efficient development of a wide range of the land in a short period of time.

IPC: G02B1/115
Filed: 1988-03-31
Abstract: PURPOSE:To obtain the title filter with excellent electrostatic field preventing function and easy to manufacture by including a dielectric film layer having the resisting value of 10<5>-10<13>OMEGA/sq. in a multi-layer antireflection film. CONSTITUTION:The resisting value >=10<5>OMEGA/sq. of the dielectric film layer is sufficient for attaining only the electrostatic field preventing function, and when the value exceeds 10<13>OMEGA/sq., the function is not recognized. The substance of the dielectric film layer with the electrostatic field preventing function as mentioned above and the excellent film thickness controlling property and uniform distribution etc. at the time of forming the film is exemplified by TiO2, Ta2O5 or Al2O3, etc. The preferable film formation of the filter is constituted of a middle refractive index layer as 1st layers 1a, 1b and a high refractive index layer composed of TiO2, etc. as 2nd layers 2a, 2b and a low refractive index layer as 3rd layers 3a, 3b, in case of the antireflection film being constituted of 3 layers. When the filter is mounted on a CRT, etc., an electron is led to the dielectric film layer through a grounding, whereby a negative potential generates, and a positive potential at the front of the CRT, etc. disappears. As the result that the potential is zero, the electrostatic field prevention can be attained.

Title: Film forming method
Inventor: KYODA MASAYUKI
IPC: C23C16/40
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain an uniform film thickness by the following method: quick heat nitriding treatment is given to the surface of a substrate, then a reactant gas, the main component of which is pentaethoxy tantalum, is let flow on the surface while changing the flow direction a predetermined number of times. SOLUTION: Quick nitriding treatment (RTN) is given to the surface of a wafer, which is a polysilicon substrate, then film deposition treatment using tantalum oxide (Ta2O5) is given. When charging a tantalum-based gas used for film deposition, the diagonal flow of a reactant gas is changed at least twice. For example, the gas flows from a charging line 17 to an exhaust line 20 for a preset time period, then the direction of gas flow is reversed so that the gas flows from a gas charging line 18 to an exhaust line 19. By this method, an almost uniform film deposition can be obtained over the entire surface of the substrate.
