Title: Disaster preventing method and disaster preventing structure for underground structure
Inventor: MORI NOBUO
IPC: E02D31/08
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To float an underground structure upward by providing underground walls to surround a fixed region below the underground structure, and displacing the underground walls inward via the water pressure of the outside ground when the ground is liquefied. SOLUTION: When the liquefaction of the slant ground occurs by an earthquake, cutoff walls 5 and partition walls 7 integrally resist the flow pressure of the ground. An underground multi-purpose duct 1 is hollow, the water pressure on the inside of the cutoff walls 5 is smaller than that on the outside, the cutoff walls 5 are pressed and displaced in the direction shown by an arrow (q) by the pressure difference. The space S2 surrounded by the cutoff walls 5 and partition walls 7 has no creephole of underground water, the water pressure is increased, and the increased water pressure acts to the base plate 1a of the underground multi-purpose duct 1 as uplift pressure, therefore the underground multi-purpose duct 1 applied with no pile support is floated upward. The upper end sections 5b of the cutoff walls 5 function as guides when the underground multi-purpose duct 1 is floated.

Filed: 1990-05-22
Abstract: PURPOSE: To compensate for misalignment between an apparatus and a workpiece by supporting a tool carrier by means of an elongate elastic member, and enabling the transverse adjustment of a tool parallel to the axis of the tool carrier. CONSTITUTION: A housing 12 is connected to the wall 15 of a chamber 5 by a plurality of rods 14 made of spring steel. An extension shaft 22 is axially displaced to slide a column 1 from a collar 25 along an annular member 4 to displace the tool 2 beyond the end of an extension 8, while the rotation of a housing 23 imparts rotational movement to the tool 2. If slight misalignment exists between the tool 2 and an object to be engaged by the tool 2, slight displacement of an apparatus which occurs during engagement is absorbed by the movement of a housing 21 along mutually meshing splines 19, 20, whereby any slight misalignment between the tool 2 and the object to be engaged with the tool, such as a screw, can be corrected by the rods 14 made of spring steel.

Abstract: PURPOSE: To improve an integrating degree, by beforehand shooting ions for forming element separated regions to a substrate, and by utilizing a mask for that, in a biporay IC that a collector buried layer is previously made up.  
     CONSTITUTION: A p - -type Si substrate SiO 2  film 2 and a Si 3 N 4  film 3 are successively laminated, the Si 3 N 4  film 3 of portions functioning as separated regions 9 is removed and p +  diffusion layers 5 are built up by shooting acceptor ions. The SiO 2  film 2 on the p +  diffusion layers 5 is once removed, and a thick SiO 2  film 6 is formed on the p +  diffusion layers 5 by oxidation treatment. The Si 3 N 4  film 3 and the SiO 2  film on the whole surface are removed only by the first thickness, and a collector buried layer 7 is made up by diffusing a donor. When the SiO 2  film 6 is perfectly removed and an n-type impurity dope Si layer 8 is grown, the p +  diffusion layers 5 are upward grown, and P +  element separated regions 9 are built up. Thus, accuracy and in its turn an integrating degree can be improved because a process of manufacture of photo-resist is completed only at a time.
